We took this solar panel with us on a 4 day backpacking trip. This kept the charge on my phone and my wife's phone. In the sun it would charge to 100% in about 1.5 hours. It worked even in light cloud cover, but charging was slower. Excellent product!

Good solar panel for charging power banks while camping. No full sunlight for the panels to work

I was looking for a charger for camping. Easy, convenient and quick to charge, this solar panel surprised me. Advise

Well it's a pretty good product, I was surprised by the quality. I have to say that my cell phone, a Samsung S10e, does not charge it at high speed, but I will modify it since I use it with my cell phone cable, and I don't think it would be compatible with my cell phone, but I charge My girlfriend's devices connect to her cell phone very quickly and are not in contact with the outside world

To my surprise, it charges my tablet quickly in full sun. In partial sunlight, charging occurs at a lower cost but is still very acceptable. Great purchase.

The 20W solar panel I tested is a high quality product that offers an efficient solution for producing clean, renewable energy. The solar panel is compact and lightweight, making it easy to install on any flat surface, such as a roof, RV or boat. I found the performance of the solar panel to be quite impressive, especially in direct sunlight. Even in cloudy or shady weather, the solar panel is capable of producing a significant amount of energy, making it a good choice for anyone looking for a reliable and constant source of energy. The solar panel is also durable and sturdy enough to withstand the elements and weather, making it ideal for outdoor use. In addition, its elegant and modern design fits perfectly into any environment. The only thing that could be improved is its ability to store energy, which means the solar panel may not be able to power powerful devices for long periods of time. However, when used with a suitable battery system, the solar panel can provide reliable and sustainable energy for everyday tasks. Ultimately, the 20W solar panel is a great choice for anyone looking for a clean, renewable energy source. With its reliable power generation and weather resistance, this solar panel offers a great solution for any situation that requires an autonomous and sustainable energy source.

This charger is very durable and is made from high quality monocrystalline cells, meaning the cells are more efficient and perform better in extreme temperatures. I really like the design of this charger. It is stiff enough to maintain its shape when pitched or leaned and flexible enough to hang over curved tents, cars, etc. The charge controller seems very smart when turning off and on when there is enough light, and I also appreciate the LED that shows when the battery is charging. The charger is lightweight and folds down to a convenient size for storage in a backpack or briefcase. I used the charger to charge my backup battery or charge my phone directly. The sun is the biggest challenge with solar chargers - you often have to be creative to place the panels to get the most light, and this charger has eyelets on the corners for attachment with carabiners, cords, etc., so I can always find it can be a good position to maximize the load. I used the charger during a motorcycle camping trip and was able to use the charger in the tent or on the bike and strap it over my tail bag to charge while riding. I also appreciate that there is no battery - I prefer storing the battery separately as I can then choose which battery I want to take with me or just charge my devices directly. Additionally, these panels should last much longer than the battery cells.

The panel is very well made. I haven't tested it outdoors yet, but it looks sturdy enough. The information in the product description is correct. I've already charged a few batteries with it and can't find anything negative. Of course patience is required! The panel also delivers a maximum of 20 watts. But if you put it in the sun, it will definitely generate electricity. This works even if there are some clouds in the sky. Then of course not at full power.

I've had the solar panel for a year now and I'm still thrilled. But I have to say that I only have the 15 watt panel. For example, I'm currently charging my iPad with it and it works without any problems. In my opinion, the workmanship is high quality for this price and you have to act roughly so that something breaks. But it really only works in direct sunlight. But I don't know it any differently from other panels. At festivals everyone is always excited and wants the same thing because they think it's so great. It's a bit rigid and you can only fold it and not bend it! I just don't go hiking with it. Maybe it's too rigid for that! For my standards the thing is great and I also think the price is great. Clear purchase recommendation!!!

I was able to test the part extensively over the weekend. Power bank with 20k was charged in just over 5 hours. Cell phone with 5k battery in about 1.5 hours. Clear recommendation
