CONXWANSolar Charger Power Bank – 27000mAh USB C Solar Phone Charger with 3 USB Outputs with 4 Foldable Solar Panels Battery Pack Charger Compatible with Most Smart Phone

I’ve bought solar chargers that stop working after a month.Bought this back in January of 2024.It is now April 2025. I used mine at least four days a week for about two hours a day, and after a year and change of constant use, the solar panel finally stopped working at max efficiency. Still works as a charger block, but definitely high quality for the price.

We use this all the time. Great for backpacking or camping.

So far so good.. It completely charged my Samsung A13 5G (5000mah battery) 4 times and my PS5 Edge controller completely once before it was flashing low battery. Fast Charged with my Samsung Charger block, ~14w took about 8 hours to charge back up. Will update once I get the solar charging data. Seems the fast charge function when my phone is charging only lasts a couple minutes (on the usb-C plugin) then reverts to normal 2A charge rate. Using the regular usb cord seemed to be better at charging my phone, didn't say fast charging but it charged it relatively quickly.

Great device, a little heavy but carries a lot of charging power. Splashproof and solar charging. Very very easy to use for its size.

After being without power for five days during the May derecho, I wanted to add to my power bank collection. Having an option that could recharge outside seemed to make sense. When Hurricane Beryl made landfall just a few weeks later I was prepared and able to put the CONXWAN Solar Charger 27000mAh power bank to the test. Before the storm I charged it by plugging in to bring it up to full charge. After our power went out, it charged my Samsung S22 a couple of times, plus a full charge to my Kindle Fire and was only at about 50%. I put it outside in the sun for about 8 hours and it was back up to full charge. I'm not sure exactly how long it took, but it was ready to go when I brought it inside. I'm hoping it's a long time before I need to put it to work again.

The solar charging feature works wellThis a great little device for recharging phones and ipads.When I was doing extensive cross country flying I kept one in my flight bag in the cockpit. Why - The cell phone is a great aid in finding people in the wilderness. It is not just the call feature . In situations like the New Orleans hurricane where power was out, cell towers were down the message service will work in the tinyest bit of space on the cell network. But the cell phone is useless without a source of power .A more casual use is to simply know that I could keep the phone and ipad fully charged working on remote sites.Mine stays in the trunk of the car.

nowhere even close to advertised capacity. 8 hours in direct sunlight was enough to charge my phone from 0-4%4% folks. so, as long as you have 25 sunny days in a row, you could charge your phone one time!Amazon seriously needs to clamp down on 3rd party sellers peddling garbage like this. To top it off, Amazon gave me a huge hassle to return it, despite advertising "free returns"paying for return shipping on deceptively advertised, non working garbage is not free. it took an hour of being stonewalled before Amazon finally did the right thing and fully refund me.I am not sure what else Jeff wants besides the worlds biggest sailing yacht and his own space program.

Helena & mostly Milton knocked out power here in Florida for few days and my 25000 Mah power brick only lasted so long decided I needed another one. Testing video on YouTube showed devices like this with multiple solar panels charger more than single ones like my 25000 Mah with one panel charged only 10%. Nothing fancy about this with only 3 ports in/out and no great flashlight but has a 27000 Mah capacity. Well see how well it works out but solar panels aren't very efficient in first place but if like my other one if it works to 10% x 4 that will be enough power for me.
