I used these to power pet water fountains out on the deck. I left them out in numerous rain storms so much so that I could pour water out of them. I let them dry out and they still charge and power my fountains.The flashlight is fabulous. The packs themselves are kind of big and bulky they aren't something I would want to walk around with and will not be comfortable in your pocket. The solar charging like others have stated will allow the battery pack to last a bit longer but don't rely on it to charge the pack quickly. On my pet fountain out in the northeast summer sun they lasted a week, so they performed very well on that front.To sum all this up in bullet form1. They performed well and the charge lasted a good amount of time.2. The flashlight works well3. When charging the pack from a wall receptacle they charge well.4. I literally poured water out of them on more than one occasion and they still take a charge and power my accessories6. Solar doesn't really charge them, more like if you leave them in the sun they will discharge a bit slower.Over all I would buy these again to use as emergency lighting and power for blackouts and to power things around the house. They would also make excellent power banks for road trips and to keep on hand in the car for emergencies. To carry them on a day hike I probably wouldn't do.I considered taking a star off for the solar charging not really being good. But they have excelled in every other area that for me it's not a big deal. If solar charging is for you then this isn't the product for you. I would purchase these again in the future. Read more

I have used this product for about a year now, on a few separate occasions.Pros:A good amount of capacity- can charge my Galaxy S25 at least twice.Works as advertised- solar recharging is a nice feature and makes it an ideal camping companion.Rubber cover for ports keeps it protected from rain and moisture.Doesn't seem to be fragile. Took it camping and used it off and on here and there and it didn't suffer any damage, though I wasn't particularly rough or careful with it either way.Flashlight feature is nice. It's not like the greatest flashlight or anything but it will do in a pinch and better than not having one. It's decent enough to be serviceable to help you find your way outside your tent at night for a bathroom break or something.Cons: Is a bit on the large side, but I imagine if it were smaller, there would be less area for the solar panels, and result in charging being even slower.Charging the unit via solar can take a while. I suppose it's the nature of the device and the fact it holds a lot of juice, so I'm not really upset about this, but it's something to be aware of.I would have liked to have seen integrated cables on this unit, that would have been super convenient but not having them is simply a missed opportunity, not a fault of the product itself.I was originally going to give this product 4 stars because there are some nitpicks, but as I wrote this I realized that ultimately, none of these nitpicks detract from what this product is supposed to do which is be a power bank that can be charged by battery. The flashlight is just a bonus feature, it's ok it's not the greatest- it's functional and that's all that matters. The fact it's a little on the large side and solar charging takes a while is just part of it. You're not gonna rapid charge a battery with sunlight, especially not with a smaller sized unit. So given that this product still works fine a year later, and does exactly what it says it would do- yeah, I'm pretty pleased with it. I got what I paid for and it works well. Read more

When plugged into a wall outlet, it charges fully in a short amount of time, and the battery holds its charge for extended periods. With its dual USB ports, I can charge two devices simultaneously, which is a game-changer for family trips or group outings. Overall, the [Brand] Solar Power Bank is an excellent investment for anyone seeking a reliable, eco-friendly charging solution that delivers when you need it most. Read more

I purchased this solar battery bank to power my GPS, phone and flashlights while hiking for multiple days. I strapped it to the outside of my pack and it maintained a full charge in the sun and provided more than enough power for all my electronic devices. The light is adequate if needed, and the bank is sturdy. A little heavy but the peace of mind of plenty of power is worth it. It sits in the sun on the window sill when not in use and I’ve never seen it low on power. Read more
