ROMOSS 30000mAh Power Bank, Portable Charger Sense8ps pro, 2-Way Fast Charging PD30W Type C, External Battery Pack Compatible with iPhone, Ipad, Galaxy, Android and More

this power bank is the bomb. it holds power for at least 3 days charging various items - especially my phone. i never travel without it. My family loved it so much i have ordered more

I have an application that uses many power banks. So far, I have brought dozens of power banks from many different manufacturers.Most power banks advertise Ah capacity base on the Li battery, which is 3.7V. I convert Ah to Wh to have a uniform comparision.This unit advertise as 30000mAh, which work out to be 111Wh. After repeated tests, I was able to get 86 to 91 Wh, which is about 77 to 82% of advertised capacity. To put this into perspective, 90% of the power banks I have only deliver 40% to 75% of advertised capacity. So 77-82% is very good.What I like most is its ability to regulate charging current base on how full the battery is and temperature. When the battery is empty and at room temperature, it can charge at a high rate of 20V 1.4A for quick charge. As the battery getting warm and charge up, charging current is automatically deduced to protect the power bank.The only negative about this power bank is the price, which is more expensive than other power banks I have.

I bought it to charge my stuff while at work. Good quality, holds a charge fairly well (i get bout two days worth). The function is good, can charge two items at once. And the size is decent, not super bulky, fits in my hand and im small in stature. Value was good, well worth the investment, i might buy another in the future.

This is an awesome power bank. It’s got a wonderful display to show your battery percentage and it’s of high quality. It charges fast and I love the white color. It’s beautifully designed. Because it’s such a powerful, large capacity power bank, of course it’s going to be a little bigger in size. This would be great to use around the house or if the power goes out but if you’re planning to travel with it, you would probably be better off getting a lighter one. I think this brand sells smaller capacity, power banks, which would make it lighter, so check this brand first because it is a great quality product. I highly recommend.

Display went bonkers and would not respond to other devices. I tried to charge it but I finally had luck with a thunderbolt and another quick charging cable from outlet to power bank. Seemed to have jumped it out of a coma and has been working since.Id like to know if putting a standard 220v house type outlet onto this, is possible.

Charges iPhone 13 fast, supports fast charging, from like 100% to 97-96% for a 30% chargeNow charging the Power bank itself, small thing I don't mind but I can it get it from 80% - 99%, but I don't know if it can get to 100% or some kind of visual glitch or something.

30000 mah. Can fast charge using the C port. The shell has a nice textured finish and it comes with a short cord, as they all do.It's about as long as a galaxy 22+ and twice as thick. It does have some weight which should be expected. I can see this coming in handy while camping, on vacation, powerful enough to supply a charge many times

PD30W Type C External Portable Battery Pack Charger With 2 Way Super Charge Compatible with iphone 13 Pro Max/13/12/11, Galaxy 22 iPad Pro Android & more. It holds charge for very long time, even when charging 2 phones at once. I recommend this product.
