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

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.

There are a lot of reviews saying solar panel doesn't work, can only charge phone a couple of times ect...It's all about reading the specks and math.Solar charging:This device is small. It's length and width is smaller than my galaxy s22 and only slightly thicker. I can easily carry it in my pocket. Putting an led in line between the Solar panel and the battery to indicate current flow is a very basic circuit. If the led that indicates the Solar panel is charging is on, there is current flowing to the battery and it is charging. There are excellent explanations in the question section which do a great job of explaining the math and why it would take probably over a week to fully charge this device. One review I read said the device would not fully charge with Solar. I "capped off" my phone from about 50% battery to 85% which used about one "bar" or one of the indicator let's. I then put it outside in the South Florida sun, in direct sunlight to see if I could fully charge it with the Solar panel. It took 3 days. It finally got back to a full charge. Am I disappointed, NO, that's about what I would expect. If you wanted to fully charge your phone, then recharge using Solar, the Solar panel would have to produce the same watage over a few hours that you used to charge your phone. You can do this with one of the folding Solar panels Amazon sells. These panels are huge in comparison to the tiny panel on this unit. It's all math and physics. Hurricane Andrew back in the day, we were without power for a little over a week. Thus device would have charged my phone once or twice, then it would probably take a week to recharge. Not what this device was designed for."I can only charge my phone a couple of times before recharging"Thus battery is small and easy to carry. If you are comparing power banks using the same technology, same type of battery, more capacity equals larger battery. Again math and physics. If the battery bank is about the same size as your phone, you are only going to get around 2 or 3 full charges with it. A power bank is basically all battery, so if the device is about the size of your phone the battery size inside is probably 2 or 3 times larger than the one in your phone. Thus expect 2 or 3 charges. Again math and physics. In an emergency situation, I would use this as a Solar flashlight. I have a larger power bank that is about the size of a lunchbox with a large folding Solar panel to charge it. Under perfect conditions I can recharge that device in about a day to day and a half. I recommend this device as long as you understand it's limitations. Remember it can fit in your pocket, It has wireless charging, and is inexpensive.BTW, the compass is just a novelty. If you are putting yourself in a situation where you need a compass for navigation, carry a real compass.

Leave on the dashboard to charge in the sun. Designed Great!

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.

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.
