YELOMIN Solar Charger, 38800mAh Solar Power Bank, Outdoor Portable Charger, External Waterproof Battery Pack 5V/3.1A Fast Charger Type C Ports with LED Flashlights, Perfect for Travel Camping

I likes this solar power bank its so useful. the Solar Power Bank proved to be a trustworthy travel companion. My electronics were always fully charged thanks to its big capacity, and the solar panel offered a hassle-free, environmentally friendly way to top off the battery. Even though solar charging does not happen quickly, it was adequate to keep basic functionality. I thought the design was sturdy and portable.

The product arrived on time and functions according to the listing description. The charge lasts quite a while, depending on the type of device that you are charging. The flashlight works well and also functions as a strobe & S.O.S. signal. It does take a few hours to charge up with the included charging wire and is described to take around three days to fully charge using only power from solar charging. The size is perfect for travel, and the weight is also low, therefore making a great addition to any camping or hiking trip. I like that the appearance is sleek and the power from the device is sufficient for my needs. The only negative that I have regarding this product is that it does not support "super fast charging" on my phone, only fast charging. Although, I'm sure it will charge my other devices in a timely manner. I look forward to using this product at the beach and seeing how well the solar charging function works.

I bought this for a 4 day camping trip and with the advertised capacity expected to get 8-10x phone charges with it across our group. Before the trip I fully charged the power bank overnight with the wall charger. On the first night of the trip I charged my phone and it was fast and great. Then I tried to charge another phone but it wouldn’t work. It kept showing flashing lights as if it was plugged into the wall or solar charging but I was no longer able to charge any more phones. It just completely stopped working which messed up the plan to charge the group’s phones for the trip, so my phone died before the end of the trip. The solar power feature is useless when it won’t even charge more than one phone after a full charge. I am returning and buying a reliable non-solar power bank.

Very handy high powered charger. Multiple charges for fellow travelers on my cross country plane ride and on numerous road trips. Nice flash light, compact, easy to take along. Easy to recharge. Would purchase again and recommend to family and friends.

I have several of these power packs of different makes and models. I bought this one Knowing damn good and well that little solar panel really doesn't work it will keep a maintenance charge on the unit but if you think it's going to charge the entire unit up automatically you're thinking about 9 days in good sun without any use. I knew this when I bought it. In my backpack there are two folding solar panel units that will easily charge this up in a few hours of sunlight. About as fast as you can do it with a decent wall charger. This being said I'm completely satisfied with this particular unit it will charge up my cell phone maybe four and a half five times on a full charge. It will charge up my Chromebook at least once almost all the way charged. And it has absolutely no keeping my little micro rechargeable flashlights charged and running my qrp radio on low power. That way I can save my actual transmission packs for actually transmitting. If you pair it is with a decent little 15 watt or better folding solar panel set you will have a decent little outfit for disasters camping Etc

The Solar Power Bank proved to be a reliable companion on my recent trip. Its large capacity kept my devices charged throughout the journey, and the solar panel provided a sustainable way to top up the battery without issues. While the charging speed via solar is not rapid, it was sufficient for maintaining basic functionality. I found the design to be portable and rugged, making it ideal for outdoor adventures and not worrying about running out of battery power.

So if I just rate this as an actual battery pack it works fine just like every other battery pack I have for the most part. I fully charged it at home before going on my camping trip and it was fine using it as a battery pack from that charge. Unfortunately, despite the fact that I was camping in an open field with full sunlight and leaving it out all day, it really never gained additional charge from the sun and was pretty much useless after the initial charge. As far as the flashlight goes, it came with no instructions whatsoever as to how to use the flashlight and frankly I never figured it out or cared enough to try any harder so that I can't speak to (or mine is broken?) It does seem a little extra sturdy and having the little carabiner clip on the side makes it convenient to attach while you're walking around or for hanging it someplace so you don't lose it in your tent when it gets dark . Overall decent battery pack but I wouldn't spend the extra money for the solar or the flashlight. I'd just get a regular battery pack next time.

Solar charger. It is great for in the car. At home it stays by the window So it is always ready to go, and plug my phone into it while I’m working. It is compact and reliable. I recommend.
