FEELLE25000mAh Solar Power Bank, Solar Charger with 4 Solar Panels Waterproof Portable Battery Charger Dual USB 2.1A Output Compatible for Smartphone, Tablet, GPS

Bought this to take camping. Love it.

To start with this product seemed great when there was sun it would charge and hold its power after a couple of months it would not charge as quick and the device would not hold its charge to the point now it does very little.

Although slightly heavy, the capacity (25000mAh version) is fantastic and lasts me more than a month as I only occasionally use it to charge my phone and at times non stop with some other peripherals when I have no access to a USB power source.Be aware that this pack does take quite a while to charge and it is not advisable to charge it using just solar power (it'll take forever, and the manual also states that it is only meant to be used as a last resort)One last note is the rubber USB covers (to make it water resistant), they have tiny little lips to get the cover out of the port, and I can see these breaking off over time, which would make it incredibly difficult to remove the rubber cover and access the port, but if you're careful with them, you should be fine :)

OK in full sun it really has to take the sun's heat. Not a clue if that's damaging? But they are solar panels so here's hoping.It feels quality. Well constructed and protected panels held firmly together. I hung this up at the beach hut and was able to have a phone all through the day at 100% - so very happy.I would state that there are fixing points needed, if used for walking or hanging I can't see how it's possible to use this on the road without fixing points?I guess if they came up with some velcro or eyelets this would be perfect for all? Not a clue if it's waterproof - not tested but it charges in little sun. Good gear.

It is okay as a battery bank, though very overpriced for what it is.Solar charging does NOT work! I have had it in direct sunlight on several occasions and all it does is drain whatever charge is left in the battery. Almost a year of having it, I can say it is a TERRIBLE outdoors product, I regret spending money on it.

Fantastic power bank, I am really surprised how good this is. I thought the solar charging would only work when the sun is out , but to my surprise it charges itself even in just daylight ! There is no need for sun although it takes a little longer to charge in daylight. The solar charger charged my phone very fast. I used it for 2 days while on a road trip and I had no problems at all. Much quicker to charge the solar bank with its own charger.

Love it! Fully charged our phones 4 times while we were camping and still have 3 bars left. I might get a couple more and use them instead of installing a battery into the van!

Bought this as a present for my wife so it hasn't been used yet but I already have one of these and they are fantastic.Perfect for hiking, camping etc. - very highly recommended.
