Easy to use. It recharges quickly, no more than 10 hours for a full charge. After that, you can charge your phone 3 to 4 times. I've used it for my computer a couple of times, and yes, it works perfectly. It also shows you a percentage of the remaining battery life.

PROS: Comes with a type c to c cord to charge up most android and iphone phones/tablets. Holds a charge pretty good so you shouldn't have to recharge it for a couple days at a time. charge up time is about 2 1/2 hours. CONS: No wireless feature and it's pretty big so can't fit in your pocket. at least not this one. They do make one that's smaller though.

Very good product with less cost. Easy to use and quick charging and compact to carry in pocket

[Employee of bestbuy] Quite a heavy battery but the longevity is so worth it, I've had this thing die on me maybe twice in the past few months that I've had it, and I've used it a multitude of times. It's size does occasionally get in the way but it's honestly negligible considering the battery life it provides. I'll never go back to the old power banks that don't show battery life on a screen with an actual number. No more 3-5 dots indicating battery life.

This thing is a lifesaver. The high 20,000mAh capacity means I can charge my phone multiple times before it needs a refill. The USB-C and 3 ports make it really convenient, and the LCD screen is a nice touch—no more guessing how much battery is left which is to me a big feature. It’s fast, reliable, and perfect for travel or everyday use. Highly recommended from me!
