Power Bank Solar Charger 46800mAh Built in 4 Cables 3 Foldable Solar Panels, PD20W Fast Charging Portable Charger, LED Display Powerbank USB C in/Output, External Battery Pack with SOS Camping Light

I needed a battery pack I could use off grid . I need to charge phones, fans, lights etc when I am out in my farm utility vehicle. I wanted a battery pack that is flexible USB C and Micro usb too. The battery pack can be charged in the house via USB C cable or charges slower outdoors using its 3 solar panes. The battery pack also has built in cables for USB C, Micro usb, Apple lightning plug, and USB-A plug. The solar panels fold in to form a smaller rectangular package that fits easily in glove or console. From a full battery I charged my Fan light (from 60%to full) and my smart phone. The pack was at 76% when all was charged. While charging the or in use the pack has a window that shows percentage left /or charged in a window.

We've been using this 3 panel folding power bank for 10 months now, and it's THE BEST! HANDS DOWN! Solar charging power bank we've ever used. It has a very good capacity battery (it's got some weight to it), the specs seem to be accurate, which is nice, compared to the other brands out there. It also supports fast charging.We've tried the ones with 4 solar panels, 5 solar panels, etc. (many different styles and brands) and none of the ones we tried charge fast (Some of them barely charge at all), except for this one.It fully charges in less than 2 days, if you keep it in a fairly cool place with good sunlight. (Don't let it get too hot when it's charging, that's the secret to this solar power bank charging faster and lasting longer, it actually charges best if it has some shade).The seller HQF-US is great! to.

I've only been messing with it a few days, but so far so good. Out of the box it had a 92% charge. First thing I did was charge my Samsung a51 phone that was at 49% it took just under 30 minutes to full charge. Then I charged my Kindle Fire 10" tablet that had a 55% charge. It took about 40 minutes to full charge. The Jinepin was at 45% when I was done charging those devices. Next I needed to go to the store so I put this charger in the back window of the car. I was gone for an hour and a half. When I got home it had 74% charge. This is my first device like this so not sure how to compare, but I like it. Gonna finish charging it through the wall outlet, but don't expect any surprises. Just comes down to longevity. If I get a few years out of it it'll be great.

I purchased the Power Bank Solar Charger (46800mAh with 4 built-in cables, 3 foldable solar panels, PD20W fast charging, and LED display). After charging it overnight using a wall outlet, it reached full capacity by the next morning. I tested it by charging my phone, and it delivered an 18% charge in 10 minutes while using 10% of its own battery.The charging speed is solid and matches what I’d expect from a 20W fast charger. The battery usage during this test seems consistent with what’s typical for a large-capacity power bank, especially when accounting for power loss due to conversion and cable resistance.The only reason for not giving a full 5 stars is I haven’t yet tested the solar panels or used it extensively in different conditions. But based on initial performance, it works as described and seems reliable.

Why did you pick this product vs others?:Love it. Helps keep me communicating when not close to home or car. My grandson’s phone was dying and I said I have something to help charge it. He was amazed. Grandma you have all kinds of crazy things in your purse but this one is cool! I highly recommend it and being cool!

Came in handy during a thunderstorm with lightning and did not have my electronics fully charged during electrical outage

I will update this review with the final results (See bottom for updates), but I am currently running this unit from a fully charged state to zero on an electronic load tester using a 5V/3A load (equivelant to a USB Fast Charge). So far, I am only at the 50 minute mark (around 2600mAh) and the display is already showing only 70% charge remaining.I will post a picture of the final test when complete. Other than that, I love the unit's features - love being able to trickle some extra power from the solar panels, like the built-in cables as well as the traditional USB ports.Compared to several other power banks I have, it is physically quite large. If the battery capacity tests out to be anywhere close to the rated capacity, the size is fine.... but... if it tests much lower, then it's excessively large. Can't wait for the results of the test.UPDATE #1: Test is complete, results are not good. This unit managed a 3 amp (average) load for 3:18:23 with a final result of 9,918 mAh of capacity which is less than 1/4 of what is advertised. This means it would charge a modern cell phone fully only twice (assuming 3,500 mAh average for most phones nowdays).I will run another test with a 1 amp draw, which will likely produce higher results because of inefficiencies in the voltage boosters used in devices like this - but it won't dramatically change the result. Too bad, I really liked the features on this device but not enough to keep it despite the false advertising - it will be returned.UPDATE #2: Ran 1.5 amp test, expected slightly different (higher) results - but, as expected - not THAT much different. On the second run, the device managed 11,340 mAh with a 1.5 amp load. Still - less than 1/4 of what is advertised.

Charges faster than my other one usually within 3-4 days. Will endlessly charge a galaxy watch or a Motorola g stylus 2-3 times
