80000mAh High Capacity PD 30W Power Bank Fast Charging 22.5W Portable USB C Battery Packs with 5 Outputs & LCD Display Battery Bank for iPhone, Samsung, iPad ,Macbook & Outdoors Camping (GREY)

Works well. Capacity was just what they claim using a known load over 48 hours. Two helpful things to know. If you plug in more than 1 device, they all charge at 5V, even if one is plugged into the type C port. This is because there is only 1 power regulator inside. Second is it only recharges at high speed through the USB C1 port. Not sure why. The weight is impressive... It weighs 3 lbs but I think you could still carry it all day. Lastly, my built in light doesn't work. No big deal.

Charged 3 phones and a blue tooth speaker for 4 days while camping. Was still 60% charged. After 2 weeks of running my phone and speaker off it im finally down to 25%. It does take a day or so to charge back up but defiantly worth it. It even has a super fast charge port will charge my Galaxy in about 25 minutes from 10% to 100%. Definitely best power bank I have used

Slow, but very high capacity. You aren't going to charge or discharge it quickly, but it's rated for 296Wh and it actually is. I discharged it from full through a meter at a constant 5v/2a and got 269.4Wh out. Charged it at whatever the input port will take (I don't remember what it defaulted to) and it took in 352.58Wh. In other words, it might actually be over 80,000mAh, but I won't know for sure until it's been cycled a few times as many cells have a higher capacity their first few cycles. As with the vast majority of power banks, the converters could be more efficient. But for the price, you'd be a fool to complain. The light works. Don't really have much to say about it though. Would I buy this again? Yes. If you value raw capacity and are ok with 30w at most, you should get one too.

So far so good funny thing about this. It came on a day that my house had no power due to retrieve hitting the line. It charged all my devices when it came including My Son’s switch, but it will not charge my ROG ally but that’s my fault as the wattage is too low but for everything else it works great

I was sent a defective one, pressing the lights and power button doesnt work. The only charge port is the top usbc and the others wont power on to charge. Very unhappy with my purchase and sending it back after I already fully charge it.
