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

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.

Konfulon offers excellent capacity for a durable power bank. It was optimally charged to 78% capacity from the factory when it arrived, which follows the 3/4ths rule for charging power sources for later use. This power bank offers the option to use two USB-C 30W PD cables for super fast charging times. It has multiple functions such as a 4-LED bulb light, LED power level readout, 4 USB-A outputs, 1 USB-C 30W PD Output for quick charging, and 2 USB-C Inputs for 3X supercharging the power bank (60W Max using two 30W PD QC 3.0 chargers). I bought this mostly for powering a 9V 18watt USB electric blanket during 1-3 day power outages and emergencies during the winter to take the edge off at nights. My plan is to buy two more of these power banks to extend my range out to a week of nightly warmth running the blanket at 7 hours on high each night. If you need big charging capacity for any of your devices, you will be very satisfied with this power bank for all its specs, price, and features.

Working just as advertised.

Phenomenal portable power. Thank you for this, has, is and will continue to serve me well.

Good product but be mindful that this charger does not qualify for TSA air travel. You may have to abandon during checkin at airport.

The Light is only for showing, not really bright. The item is heavy, large capacity.

I took it camping and was able to charge my phone all weekend and used it on my heated sleeping bag. Used 25% of the battery life worked perfectly
