KONFULON 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

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

I have two of these 30W high capacity power banks, and I use them for keeping my 5th gen Ipad Pro 12.9 powered up. I use my Ipad every day for at least 4 hours, and can generally get about 3-4 days out of one of these fully charged power banks. Because it is such a powerful power bank, it takes longer to fully charge them…up to a couple of days depending on whether I use the USB-a or USB-c connection. It is otherwise very functional and portable…and with all of the devices I have in my home, I’ll never be without a backup power source! I would say it’s not a backup source you would want to carry around in a handbag or backpack because it’s as heavy as a brick! It comes in handy for me because when I am working, I am hardly ever sitting near an outlet that I can plug a power cable directly into.

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.

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.

Love this thing, I do a lot of 3-4 day camping trips and this thing charges my phone, my lights, weed vaps, and fans for an entire trip. It’s big but it encourages you to keep it on a table while charging which is a good thing because smaller ones get damaged frequently when carried or after falling while charging with cords plugged in.

Working just as advertised.

Lasts forever. Works great and charges with USBC. Takes a while to charge but it does last forever. Looks great. Only issue is I can't pronounce the company's name.

Heavy but worth it. We got four kids so that means in our house we have four cell phones two tablets and other devices I can go on the road for 2 days with these guys and all their stuff and charge everything and keep everything running

Came 75% charged Took me a little bit to figure out how to get it to come on and off push the power button twice to get it to come on push the power button twice to turn it off The light is the same push it twice to get it to come on and push it twice to turn it off. Haven’t figured out how you get one light two lights or three etc. to come on instead of all of them. I waited at the post review because I wanted to see how long it was gonna charge. It’s been plugged in for two days and it’s at 93% so it is really really slow charging the battery and I’m assuming it’s gonna take longer to wear it down.

Quality! Took a long time to charge the first time. But since, its relitively quick. Lasts a long time.

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

This power pack can charge my phone MANY times before I need to recharge this beastly bank!
