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

Love this product. It worked great during our power outage and self charged in the daylight

Lasted a good minute through DisneyWorld in Florida you feel me parents!! Highly recommend.

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

Great power source and as a flashlight. Doesn't charge well on solar though. A whole day or two still won't do it. I'm always using it for something. Several years now and still working great.

I knew from reading the specs that the solar charger would be completely inadequate to charge this bank, but I didn't think they would blatantly lie about the capacity of the storage. There is no way that this is 38800mAh, as it could literally only charge from full capacity to empty my Samsung Fold6, which only has less than 5000mAh capacity, and it couldn't even do that. I have a 20000mAh power bank that seems accurate, as it can charge my phone fully around 5 times, and this bank is smaller than that. Buy if it's a great discounted price, but be aware it won't solar charge to any useful amount, and the storage capacity is nowhere near 38Ah.

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 my sister who loves camping. I worry that she will get stranded with a dead phone so I bought this to take with her. It gives me some peace of mind to know that she can charge it in the sun if needed. You can also charge it indoors like a traditional power bank since this method is faster. It seems well made and durable. She has already dropped it a couple of times and it works fine. It has a pretty big capacity so it can charge her phone and laptop multiple times before it needs to be recharged. I really appreciate that it can be used as a flashlight as well. Now she has one less thing to carrying around in her bag.

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.
