2023.05.31 10:39 AES202209 Advantages of portable outdoor energy storage
![]() | Energy storage is perfect if you need to charge personal electronics and small appliances while away from your household AC outlet for extended periods of time, or if you want to have backup power ready in case of an emergency. submitted by AES202209 to u/AES202209 [link] [comments] These devices are basically large batteries in a protective case with built-in AC outlets and other ports. They're much larger, heavier, more powerful, and generally sturdier than the gas-powered portable generators and portable laptop chargers we recommend. This makes them more versatile, such as camping with a lot of electronic gear, working in a remote corner of the home, screening movies in the backyard, or doing landscape photography. In an emergency, although not very powerful, they have some major advantages over gas-powered portable generators. Portable outdoor power banks are silent and have no emissions, which means you can safely use them inside the house during a power outage. And, since there's no motor, you don't have to keep gasoline on hand, or perform the oil changes or other minor maintenance an internal combustion engine requires. outdoor power bank One is about the size of a standard plastic milk crate and weighs 50 pounds, which you probably wouldn't carry around in a backpack or briefcase. But you can charge your outdoor power banks overnight at a wall outlet (recharging most of them from empty to full takes 12 to 24 hours), or leave them in the sun with a solar pack, Pack it in the trunk with the rest of your gear, then power your phone, laptop, camera, projector, GPS unit, drone, or other electronic device for hours at a time while on the go. Outdoor power banks also typically offer more output options than just AC and USB, such as 6mm DC ports and car power outlets to support a wider range of devices. Another best partner of the portable outdoor mobile power supply is the solar folding bag. During a long journey, the energy storage is easy to run out of power. The solar folding bag can solve this problem very well. Just display it in the sun, It can charge portable outdoor power banks, and can also charge small electronic products such as mobile phones and Ipads. AES PV Technology Co., Ltd. is one of the earliest manufacturers for small solar panels and has been devoted to the production of solar panels and mounting structures from 2008.

2023.05.31 10:31 JoshAsdvgi THE ENCHANTED HORSE
![]() | submitted by JoshAsdvgi to Native_Stories [link] [comments] THE ENCHANTED HORSE ( MALECITE ) There was once an old man that had a son named Louis who used to go hunting to support his parents, for they were very poor. One day while he was hunting, a gentleman came to visit his parents. This gentleman offered the old man a beaver hat full of gold for his son, and promised to take good care of the boy, whose only duties should be to tend the gentleman's horses. "In about twenty years you will get your son back," said he. The old man communicated the offer of the gentleman to his wife. She, however, was not anxious to accept it. Then the old man, goaded by the thoughts of their poverty, tried to persuade her, and he finally accepted the offer against his wife's inclinations. The gentleman waited for Louis to arrive, and then he took him away. When he arrived at his home, he showed the boy over his house, and gave him permission to eat and drink whatever he cared to. He also showed him two pots,--one full of gold and the other full of silver,--which he told Louis not to touch. Later he took him to the stable where he kept the horses, and showed him a black horse in the farthest stall, telling him to be very particular about caring for that horse. Among other things, he gave him orders to wash him three times, and to take him to water three times every day. Then he pointed out to him a gray horse, and ordered him to beat him three times a day, to give him very little to eat, and to water him only once in twenty-four hours. Further, he told him never to take the bridle off that gray horse. After this, he told Louis that he was going on a journey, and would not return for a few weeks. Louis carried out the gentleman's instructions, and, when two weeks had passed, the gentleman returned. The first thing he did was to go into the stable and examine his horses. He was well pleased with the looks of his black horse, and was also pleased to note that the gray one was looking very poorly. While they were returning to the house together, the gentleman began to play with Louis, who noted that he had a knife in his hand, and was not surprised when his finger was soon cut by it. The gentleman, however, apologized, and, taking a bottle out of his pocket, rubbed a little of the liquid on Louis' finger. Louis was greatly surprised to find that his finger was at once entirely healed. Later in the day, he told Louis that he was going away again (for a week, this time), and told him to be careful to treat the horses as he had done before. When he had gone, Louis' curiosity got the better of him. He took the cover off the pots, and dipped his finger into the golden liquid. When he pulled it out, lo, and behold! his finger was changed to gold. At once he saw that his master would know what he had done, and, to hide his finger, he wrapped it up in a piece of rag. In addition, Louis' pity overcame him, and he did not beat the gray horse. At the end of the week, the gentleman returned and asked Louis how the horses were. He was well satisfied after his inspection of the stable. Again he began to play with Louis, his knife in his hand. While he was playing with him, he noticed that Louis' finger was wrapped up, and he inquired of Louis what was the matter with his finger. Louis replied that he had cut it. The gentleman pulled the rag off, and seeing that Louis' finger had turned to gold, he knew that Louis had been meddling with the pots. He became very angry, and grasped Louis' finger, twisted it, pulled it off, and threw it back into the pot, warning Louis not to touch the pots again. He played with him as before, and again cut him on the hand. A second time he applied the liquid, and again the boy's hand was healed immediately. He again told Louis that he was going away, and would be gone for three weeks, and ordered him to beat the gray horse on this occasion five times each day. That day Louis watered the horses, and, noticing that the gray horse could hardly drink any water with the bit in his mouth, he took pity on him, removed the bridle, and gave the horse a good drink. When the horse lifted his head from the brook and looked at Louis, he had a man's face on him and he spoke to Louis as follows:"You have saved me. If you do as I tell you, we both shall be saved. The master is not a man, but the Devil. He came to my parents as he did to yours, and bought me with a beaver hat full of money. Every time he comes and cuts you, he is trying you to see if you are fat enough to be killed. When he returns this time, he will again try you, and, if he finds that you are not fat enough, he will turn you into a horse. If you are fat enough, he will kill you. If you do as I tell you, Louis, we both shall be saved. Now feed me as well as you can for two weeks; put my bridle on the black horse, and beat him five times a day. In short, give him the treatment which was destined for me." Louis did as the Gray Horse requested, and the animal began to recover his lost weight. The black horse lost weight rapidly. After the two weeks were up, the gray horse was in good condition; the black horse was very poorly. "Now," said the Gray Horse," the Devil suspects that things have not gone properly, and he is returning. Now we must prepare speedily to leave. Since his black horse is very swift, you must go and cut his legs off: cut the left foreleg off below the knee; cut the right fore-leg off away above the knee; cut the right hind-leg off below the knee; and the left hind-leg, away above the knee. He will not then be able to travel so fast, for his legs will be short and of different lengths." When Louis had completed his task, the Gray Horse told him to go to the house and get the pots of silver and gold; and, on Louis' return with them, the Horse told Louis to dip his tail in the silver pot, and to dip his mane and ears in the gold one. "And you dip your hair into the gold pot," said the Horse, "and stick your little fingers into the metal. Take the saddle and put it on me, but, before we start, go into the house and get three grains of black corn which he has upon his shelf, and take his flint, steel, and punk. Take, also, an awl, that round pebble which comes from the seashore, and then take that wisp of hay which is pointed." Louis did as the Horse bade him, and then mounted on his back and rode away. The Devil returned two days after they had started, and, when he saw that the gray horse had gone and the black horse was mutilated, he knew what had taken place. This enraged him very much, and he at once began to think how he could outwit the fugitives. Finally he set out in pursuit. After Louis and the Gray Horse had been gone several days, the Gray Horse spoke to the boy, and said, "The Devil and the black horse are pretty close. You did not cut his legs short enough. Give me one of those grains of black corn, and I'll go a little faster." Louis gave him one of the grains of black corn, and the Gray Horse traveled much faster. After a few days had passed, the Horse again said, "Louis, he is getting very close. You will have to give me another grain." So Louis gave him a second grain, and the Gray Horse increased his speed. Three days later, the Gray Horse said to Louis, "Give me the last grain. He is getting very close." After three more days, the Gray Horse again spoke, and said, "Louis, he is very close. Throw the awl behind you." Louis did as he was told, and the Horse said, "Now, that awl has made a great field of thorn-bushes grow, many miles in extent." When the Devil rode up, he was going so fast that he rode right in among the thorns, and got his horse out only after a great deal of trouble. By the time he had extricated his. horse and had ridden around the field, Louis had gained a great distance over him. "Louis, he is getting very close," said the Horse some days later. "Throw back the flint." Louis obeyed him, with the result that, when the Devil came up, he was confronted by a high wall of bare rock, which extended for miles. He was forced to go around this, and, when he once more took up the trail, Louis had gained many more miles on him. After a couple of days, the Gray Horse said, "Louis, we have only two things left, and I am afraid that we are going to have a hard time." "I think," said Louis, "we had better throw the punk behind." With that he threw the punk behind him. When it struck the ground, it immediately burst into flame, starting a forest fire which extended many miles. When the Devil arrived, he was going too fast to avoid riding into the fire, and this caused him great trouble. He had to go many miles out of his way to avoid the fire, and this delay enabled the fugitives to make a material gain in distance. In two or three days the Devil had regained the distance that he had lost. The Gray Horse now said to Louis, "I am afraid that he is going to overtake us before we can reach the sea. He is gaining rapidly upon us, and is now very close. You had better throw the pebble behind you; it is the only chance left us." Louis threw the pebble behind them; and the result was that a great lake appeared, which extended over many square miles. The Devil rode up to the lake, and, knowing whither they had gone, he travelled around it. This manœuvre cost the Devil the loss of many valuable miles, for Louis and the Gray Horse were by this time quite close to the sea. "He is still gaining on us." said the Gray Horse. "I'm getting very tired." Looking ahead, Louis could see the ocean, and turning around, he could see the Devil coming, gaining on them all the time. "Louis, I am afraid he is going to overtake us," said the Horse. Now, Louis did not understand what advantage it would be for them to arrive at the sea; but this was soon apparent. They did manage to reach the seashore ahead of the Devil, however, when the Gray Horse said, "Louis, throw out that wisp of hay." Louis pushed it out, and, behold! as he thrust it, the wisp of hay was converted into a bridge. They immediately rode out upon this, and as they passed over it, the bridge folded up behind them! The Devil did not reach the sea until they were a safe distance from the shore. "It was very lucky," the Devil said, "that you took my bridge with you, or I would have eaten you two for my dinner! " Now, Louis and his horse continued to cross the bridge until they came to the land on the other side. While travelling along through this new country, they discovered a cave. "Now," the Gray Horse said to Louis, "you stable me in here, and go up to the king's house and see if you cannot get work. Wrap up your head in order that your hair may not be seen, and do the same to your little fingers. When you arrive there, go and lie with your face down behind the kitchen, and wait until they throw out the dish-water. They will ask you what you want. Tell them that you desire work, and that you are a good gardener. Do not forget to comb your hair once a day in the garden, where they cannot see you." The young man did all the Gray Horse suggested, and, when one of the maids threw out some dish-water behind the kitchen, she noticed him, and straightway notified the king. His Majesty ordered the youth to be brought before him, and, when Louis had come, the king inquired into his identity and his desires. Louis told the king that he wanted work, and the king employed him as a gardener, because Louis claimed greater ability than the other gardeners. Every noon he would seclude himself to comb his hair, and then he would tie up his head again in the cloth. Although he was quite handsome, he did not look well with his head tied up in this manner. His work, moreover, was so excellent that the king soon noticed an improvement in the garden. One day, while he was combing his hair, the princess looked out of her window, and saw Louis' hair. She noticed that the hair was all of gold; and the light from it shone into her room as it would if reflected from a mirror. Louis did not notice her, and, when he had completed his toilet, he wrapped up his head again and went away, leaving the princess enchanted by his looks. During the same afternoon, while he was working near the palace, the princess dropped a note down to him. Louis did not see it, and therefore did not pay any attention to it. She then dropped several more, one after another; but he paid no attention to them. The next day, he thought he would go down and see his horse. When he arrived at the cave, the Gray Horse inquired what had happened. Louis related the few events to him; but the Gray Horse told him that that was not all, for he had not noticed the princess looking at him when he was combing his hair. "To-morrow," said the Horse, "the king will ask you if you are descended of royal blood. You tell him that you are the child of poor parents. There is a prince who wants to marry the princess; but she does not love him. When you go back to work in the garden, the princess will drop notes to you again, but don't touch them. Louis, in time you shall marry her, but don't forget me." Louis returned, and the princess again dropped him notes; but he ignored them. In the meantime the prince had come to see the princess, and he made arrangements with the king to marry his daughter. The princess, however, would not look at the prince. The king demanded of his daughter why she did not want to see the prince, and she told him that she desired to marry the gardener. The king became very angry; he declared that she could not marry the poor beggar. "Did you not always say that you would give me anything I wanted?" she asked of the king. "Yes," answered he; "but you must marry a prince." She again refused to marry the prince. At this, the king became very angry, and went out to tell his wife what the princess had said. "I think the gardener is a prince in disguise," the queen said to the king. The king summoned Louis into his presence; and the young man, obeying, came into the midst of the royalty and nobility of the palace, with his head still covered. The king asked him if he was of royal blood. "No," he replied. "I am the son of poor parents." The king then dismissed him. The princess, however, contrived a means to marry Louis, and, when the ceremony was over, they went back to the king. She told her father what she had done, and asked for her dowry. He told her that her dowry should be the pig-pen in which he fattened his hogs; and he drove them from the palace with nothing more. The queen was in tears at the way the king treated their daughter; but he was obdurate. The princess and Louis had to subsist on what little the queen could send them. Soon the princess said to Louis, "We had better go to the place where your parents live." "No," said Louis, "we must go where the king sends us, for his will is my pleasure." So they went to the pig-pen and fixed up a place to sleep. Every day the princess went to the palace, and the servants there would give her what was left from the table. This continued for several weeks, until, one day, Louis thought of his Horse. He went over to the cave to find out how he was doing. "Well, Louis, I see that you are married, and that your father-in-law is treating you pretty badly," the Horse said to him. "Now you look in my left ear, and you will see a cloth folded up." Louis did as directed; and the Gray Horse continued, "Take the cloth. At meal-time unfold it, and you will find inside all sorts of food of the finest kind. Come back and see me tomorrow." Louis returned to his hog-pen, where his wife had the leavings from the palace table arranged for supper. "Take this cloth and unfold it," said he. And when she unfolded it, she was amazed to see delicious food and fine wines all ready to eat and drink. This was the first decent meal that they had eaten since they were married. The next day he again went back to see the Horse, who asked Louis if he had heard any news. Louis said that he had not. "Well," said the Gray Horse, "I did. Your father-in-law is going to war to-morrow, because his daughter did not marry the prince to whom she was betrothed. Louis, you had better go too. Send your wife up to borrow a horse and arms, and you go with him." On returning to his hog-pen, Louis told his wife what he had heard and what he wished her to do. So she went up to the castle to borrow a horse and armor. The king at first refused to give it; but the queen finally persuaded him to loan his son-in-law a horse. Thus Louis was equipped with a gray mare and an old sword. Louis accepted this; and the next morning, when the king started with his followers, Louis went forth mounted on the gray mare. He found, however, that she was too old to carry him: so he rode her down to the cave. There the Gray Horse told him to look in his right ear for a little box. Louis did so, and found the article. On opening this box, he found a ring inside it. The Horse told him that he could now get anything he wished for, and directed him to wish for arms and armor better than the king's own. Louis did so, and the armor immediately appeared. When Louis had donned it, the Gray Horse told him to comb his mane and tail; and after this was done, they started, quite resplendent. While they were passing the pig-pen, Louis' wife, mistaking him for a foreign king, begged him not to kill her father, and Louis promised not to hurt the old gentleman. The fight was already raging when Louis arrived, and the enemy was pressing the king hard; but he came at just the right time, and turned the tide of the battle. Not recognizing him, the king thanked him (a strange prince, as he thought) for his assistance; and the two rode back together. On the way they began to race; for the king was proud of his steed, and was fond of showing him off. Louis, however, far out-distanced him, and rode on to the cave, where he unsaddled his horse, resumed his old clothes, and tied up his head. Before he departed, the Gray Horse told him that the king would go to war again on the morrow, and that he, Louis, should once more borrow the horse and sword. He took the old gray mare and the sword back to the pig-pen. His wife inquired eagerly how her father had fared. Louis answered that the king had been successful, and told her to take the horse and the sword back to the palace. When she arrived, she told her father that her husband wished her to thank him for the horse and the sword. Whereupon the king inquired if Louis had been present at the battle, for, he said, he had not seen him. The princess replied that he had indeed been there; and truly, if it had not been for Louis, the king would not have won the battle. The king replied that he was sure that Louis was not there, or else he would have seen him; and he persisted in this view. The princess, being unable to convince her father, returned to the pig-pen. When the princess had left, the queen said that Louis must have been in the fight, for, if he had not been there, he would not have known about it. "Was there no stranger there?" she asked. "Yes," returned the king. " There was a strange prince there, who helped me." "Well," said the queen, "that must have been your son-in-law." Back in the pig-pen, the princess told her husband that the king was saying that he had not been at the battle. "If it had not been for me," Louis replied, "the king would not have won the battle." And so the matter was dropped. The next morning he sent his wife up to borrow the horse and equipment again. The king gave his daughter the same outfit. Again Louis went to the cave, where he again changed horses and armor. Once more, when he passed his hovel, his wife did not recognize him. When Louis arrived, the battle was going against the king, as on the former occasion; but the young man a second time turned the tide in favor of his father-in-law. After the battle was over, Louis and the king rode back together. The king wished to find out who this prince might be, and he determined to put a mark on him, so that he would recognize him again. He took out his sword to show how he had overcome one of his adversaries in battle, and stabbed his son-in-law in the leg. A piece of the king's sword had broken off, and was left in the wound. The king pretended to be very sorry, and tied up the wound. When they started off again, Louis put spurs to his horse, and when he reached the cave he again changed horses. Then he returned to the pig-pen with the old gray mare. He was cut so badly, that he could walk only with difficulty. When his wife inquired if he had been wounded, be explained how her father had done it. Thereupon his wife took the handkerchief off, took out the piece of sword, and rebound the wound. Then she took the horse and sword, together with the broken piece of the king's sword and his handkerchief, to her father. She told her father that her husband sent back the handkerchief and the piece of sword, and also his thanks for stabbing him after he had won the battle. The king was so much surprised that he almost fainted. The queen began to scold the king, saying, "Did I not tell you that he was a prince?" The king sent his daughter to the pig-pen to get her husband, so that he could ask his forgiveness. Louis refused to go, saying that the king's word was law, and was not to be altered. He was confined to his bed on account of the wound which he had received. The princess returned, and told her father what her husband had said. He then sent down his chief men to coax Louis, but they were refused every time. Finally, the king and the queen themselves went down and asked Louis' forgiveness; but Louis repeated his refusal. The king rushed up, but he was mired in the mud which surrounded the pig-pen. The queen, however, was able to cross on top of the mud, leaving the king, who returned alone to his palace. The same night, Louis took his ring and wished that he and his wife should wake in the morning in a beautiful castle and when the day came, lo, and behold! it was as he desired. In surprise, the king saw the castle, and sent Louis a note, saying that he desired to wage war with him. The young man sent a reply, that, by the time he fired his second shot, there would not be even a cat left in the king's city. This note he sent by his wife, and requested her to bring her mother back with her. The king's daughter obeyed, and brought her mother back. That afternoon, the king fired on his son-in-law's castle, but did no damage. Louis then warned the king that he was going to begin his cannonade, and straightway fired. His first shot carried away half of the city, and the second swept away all that was left of it. |

2023.05.31 10:28 AES202209 What should be considered when choosing a solar folding bag?
![]() | Portable solar panels are also growing in popularity as people look for an easy, sustainable way to charge their devices. Whether you're a hardcore backpacker heading into the wilderness, or a sunbather looking to get some work done at your local park, there's a solar pack for you. submitted by AES202209 to u/AES202209 [link] [comments] Why Buy Portable Solar Panels?When you think of solar panels, you probably picture a large black slab leaning toward the sun. Portable versions of these fixed arrays use the exact same technology as solar panels, just bundled in a lightweight design. This makes them ideal for a variety of uses, from powering your recreational vehicle to charging your electronics.Portable solar panels are also a great way to get renewable energy. While you may not be ready to install a solar roof on your house just yet, charging your phone or laptop with small panels can help you gauge the light levels in your area to see how solar might be able to meet your needs. solar folding bag Factors to considerWhile most portable solar panels are easy to install and use, there is always a lot to consider when investing in a new technology. We've rounded up what we think are the most important factors to consider before you start powering up the great outdoors.PowerStart by figuring out how much power you need. Some individual panels come in many different wattages, which is a measure of pure electricity. For example, the AES Solar Folding Bag, a panel that can be folded into a compact rectangle with a handle for easy portability, is available in 100W, 120W, 200W, and 300W. Higher wattage designs are larger and more expensive, so the best panel for you will depend on which electronics you want to power.Low-wattage panels won't prove useless in your quest to move away from traditional energy sources, but they may charge your devices more slowly than you're used to. For best results, look at your device's specs and figure out how much power their charging cables will allow. This can help prevent you from buying a panel that watts more than your equipment limits Portable outdoor mobile power supply (energy storage) selectionMany portable panels come with the necessary cables and a portable outdoor power bank (energy storage) that you need to store power for later. A portable outdoor power bank (energy storage) is especially helpful if you want to use solar power when the sun isn't shining: lighting up a campsite at night, charging your phone during a thunderstorm, or keeping your batteries on a cloudy afternoon. Laptops running, are good examples. If you want to stock up on solar, consider buying a kit that includes the necessary portable outdoor power banks (energy storage), converters, and cables.It is also possible to use your solar power immediately without these additional accessories. Many portable battery boards have USB ports that allow you to charge your electronics directly. A small and lightweight option might be all you need to keep your phone or laptop running on sunny days. Forgoing portable outdoor power banks (energy storage) and wires can also help keep the cost of your solar setup low. PortabilityThe size, weight and design of your portable solar pack will determine its portability. If you plan to drive to a sunny location to get some work done, a more powerful and relatively heavy solar panel might be fine. You can keep it in your car until you reach your destination, so its size and weight won't be an issue. Backpackers and hikers, on the other hand, should opt for panels that are small and light enough not to be a burden on long outdoor hikes. Before you buy, make sure you check the weight and dimensions of a panel, as well as the weight and dimensions of all its accessories.Weather resistanceWhile most solar panels are at least somewhat weather resistant, not all are truly waterproof. The last thing you want is to ruin your brand new gadget and leave it without power just because it wasn't designed to withstand the outside world. Depending on the intensity of your outdoor activities and the weather in your area, determine the tolerance of your panels before you make a purchase.PriceThe final factor to consider is how much you are willing to spend on your new portable solar panels. There's no way a panel this small will pay for itself through the electricity it generates, but the freedom and access to the outdoors it can afford you is an intrinsic value. Prices will vary based on your panel's power output, energy storage components, and overall volume. This is related to the factors considered in the price of solar panels.AES PV Technology Co., Ltd. is one of the earliest manufacturers for small solar panels and has been devoted to the production of solar panels and mounting structures from 2008. We are one of the pioneers for small solar panels and its solar applications. We mainly focus on Portable Modules and have been developing higher efficient 545W to 700W solar panels with HJT, Top con and Shingled technologies.

![]() | submitted by emqtt to MQTT [link] [comments] https://preview.redd.it/jgtq2913x53b1.png?width=1520&format=png&auto=webp&s=db3f7937bef5b3aca39d93a77fb86108cb6976ed IntroductionWith the rapid development of the Internet of Things (IoT), the MQTT protocol is being widely used by many companies and developers. In the journey of learning and using MQTT, MQTT client tools are used to connect to MQTT brokers for publishing, subscribing, and messages sending and receiving.A handy client tool can greatly facilitate developers to explore MQTT features and debug IoT applications, shortening the development cycle.
