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)

Love this power bank! It is massive and I love that it is massive. I took this on a 4 day camping trip and it kept my bluetooth speaker, phone, tent fan, tent lights, and vape all charged all weekend and I still only used about 30% of it!

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.

tested most of the claims of the reviews and at first even chatgpt was confused but the input c2 port is regular 22.5w max port and usbc c1 pd in/out goes up to 30w while charging the powerbank. On the powerbank it is written 12v 1.5amp in input but it goes 20v 1.5amp total. The capacity is phenomenal for a powerbank... tested at over 296wh which is almost 3x 27500mah powerbanks (99wh)

Working just as advertised.

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
