Power Bank,Solar Charger,36800mAh 5V3.1A QC 3.0 Dual 2 USB Port Built-in Powerful Flashlight IPX7(Black)

Great to charge your phone when hunting where poor cell signal drains your battery. Continuous recharge in the sun. Sure I should pay attention to to the hunt but we all know the game shows up when you’re NOT looking.

These solar power banks are very handy to have, especially for camping, hiking, or during storms when power could be out. They hold a good charge, and what's especially nice is they have two 3.0 USB ports. They can also be charged by outlet. They have a built-in flashlight and compass. These are good power banks for the money, and should be in everyone's home emergency arsenal.

Has pretty good charging ability, the size is pretty big so not all that portable but still pretty easy to carry around. very durable and easy to use. Not too sure the solar charging work though.

I wanted a low price battery pack with decent capacity.Capacity: The advertised capacity of this pack is 36,800mAh and supporting QC3.0 with a max charge rate of 18W. Since there was some contention about it's actual capacity I decided to run my own tests using my USB C/A multi-meter (see in pictures). I don't need the full capacity of 36K mAh but I needed at least 15K mAh, never got close! The maximum mAh's I could push into the completely dead pack (wouldn't even register on my multi-meter) was 7,475.Charging from battery pack to device: This worked OK but I never got higher than 1.4A charging my Google Pixel 6 and my Fire HD 10. I don't have other devices to test with but these are new devices so they should be able to push the max charge into them and they didn't go higher. That said I don't know that they can accept more from this type of energy source.Charging from wall to battery pack: I used my solid USB A charger that puts out 2.1A @ 5v and it would never push more than 1.4A into the pack. Not sure if as good as it gets or if I used a "better" charger would I see faster charging. If I can find a better charger or a USB-C charger I'll give it a shot.Testing methodology: I charged the battery to full capacity. How did I know it was at full capacity? Using my multi-meter the throughput from the charger to the battery went to 0 and stayed at 0 for 10 minutes. I would then wait for about 20 min and connect the battery to a device (Fire HD 10) and set it to play youtube videos to consume juice until the battery pack was dead. How did I know the battery pack was dead? The multi-meter wouldn't even light up. Then I would charge it to full capacity, take a picture of total mAh pushed into the pack (7,476mAh max) 4 separate times and the capacity was very consistent - 7476, 7349, 7446, and 7438.Conclusion: Charges a device just fine at 1.4A but is 100% not as advertised. I'm SHOCKED that it has as high a rating as it does considering it's SO SO SO SO far from what it's advertised as. Given it has a battery capacity of 7.5K Ah you can spend you money elsewhere and get more for your money and have a much smaller footprint and weight. Also since it clearly seems like a total fraud, is it water proof or IP67 as they state, I highly doubt it.I'm returning this item now and trying a different pack/brand.

Liked the power bank and used it over weekend for a trip. The best part is it can charge without connecting to power source under the sun. Due to higher capacity, we can charge multiple phones multiple times. The USB and USBC provides couple options to charge a phone with available cables. The flash light is added feature that can be used as needed. I think this unit is great to have for any outdoor trip.

Does charge by sunlight but very slowly but still charges. It charges fast by USB, and lasts a very long time, charges devices fully, and has a very very bright flashlight. Worth the investment.

This battery pack offers a lot of features for some of them to be useless.Solar power works but takes about 3-5 days to full charge. Good feature but useless.It claims to have a lot of mAh's but honestly I got like 1 and half full charged of only my phone. Google pixel 4a.I guess the dust proof, water proof, and shock proof works but I never tested that out. But it's good peace of mind to have.The flash light is nice and bright. And the compass is a cool addition and decently accurate.It feels rugged, and it's good for the price. But honestly you're better off looking for something else.

Phone was charged on the power banks factory charge which i believe is normally around 65-70% which is 3/4 lights on the battery indicator, after 1 hour of charging it dropped to 2/4 lights which is somewhere in between 25% and 50% charge.It charged my phone about 35% during the hour charging with little to no use, phone was locked and screen off. (rounding up because I was streaming music and had a few apps open in the background for like 40 minutes).Estimated full charge: 2h 40mSolar charging immediately starts as soon as sunlight hits the panel. It's slow at charging, but i expected that from a small, cheap power bank. If you're like me and carry a backpack every day, you could clip it onto your bag and have passive charging while you're out and about.
