Solar Power Bank Portable Charger 50000mah Battery Pack QC3.0 Fast Charging 20W 2 USB Waterproof Camping Travel External Backup Phone for iPhone, for Samsung, Android (Black + White)

This product never blinked as it should to be used… finally now having time to follow up on this…. It never worked but I thought I needed to read the the manual.. now that I have read it.. I understand this product doesnt blink at all.

This product takes a very long time to charge completely. I left it in direct sunlight for over 4 hours and it was not charged very much. There are really no directions on how long it takes to charge or anything else. I have yet to charge it completely charge it. You can connect it in to a wall charger as well. Even that takes a very long time. I plugged it in over night for a total of 12 hours and it still wasnt completely charged. I guess it just takes longer than I anticipated to charge it.

I concur with the other posters- this delivers nowhere near the advertised power. By my calculations, it only has 13,400 MAh. I do not have a smartphone, and purchased this to run USB appliances. At full charge (immediately after charging, because it rapidly loses charge) it ran my lights for 2.5 hours instead of the 10 hours it would have if it were truly 50,000 MAh. The reason I chose this model because of the (fraudulent) high amp-hour rating. The best thing I can say, is that it seems to be rugged and built well. If this were a dead parrot, I'd be saying "brilliant plumage" or that it is pining for the fjords. ~~~~~~ 11/15/19: After successfully charging my iPod last week, I attempted to recharge again today. Not only did neither work, it seems to have made my iPod unable to recharge by 110. And initially it did not recharge even by computer, but I have gotten in to work eventually. I will not be using this on any device in the future. This solar power bank (of which I bought two) is now an incredibly expensive paperweight. I will try to remove a star. ~~~~ 1/21/2024. I bought this, not realizing it was the same thing I bought 5 years previous. I still am not a cell phone user; but bought this to power USB appliances. No other solar power bank that I know of lacks the ability to charge it via USB port. Guess it will be a flashlight AND an expensive paperweight.

It fulfills the functions and has good charging duration

I like this battery! I leave it in my shop so it gets a few hours of sun and is always charged up. Then it goes biking, yakking or hiking with me, just in case something runs out of power. Good value!

Great for an overnight backpacking trip but wouldn’t trust it for more than 2. It takes roughly 6-8 hrs to fully charge on a wall outlet and once it’s charge is depleted the solar portion seems useless. The compass doesn’t work so don’t trust it. Haven’t really used the flashlight option other than when I received it to turn it on and that part was hard to turn off (the button didn’t seem to want to work). I do like that it is pretty rugged, has a clip so you can attach it easily to your pack and two ports to charge your electronics.

Charged right up and was able to charge my cell phone very easily. I will use these to power up a heated vest at a bowl game this year. We will see how well they work...

Untested. So far so good

This lasted on a week long camping trip. Best part that it had solar panels to recharge itself and it does not need to be in direct sunlight.

definitely is not 50,000 mah and after being in the sun for a full day did not recharge even a little bit. used on a 5 day kayak trip where only source to recharge navigation equipment was depilated after the first recharge. very disappointed. waste of money and non returnable

Works

Mauvais backup, quand il est rempli, il ne tient pas pour beaucoup de temps

Stopped working after a month. Have now way of returning it for a refund.
