ExpertPower LED Display 20000mAh Power Bank with Type C & Micro USB Input, Dual 3A High-Speed Output for Smartphone & Tablets

Very useful when driving all day. Keeps my phone charge was draining. Also great for camping and wherever electricity is not available. Really sturdy and attractive.

Did not work straight out of the box. It showed that it was charged but would not charge any devices. Must have been the USB. Looked used as well. I was under the impression it was new. Had a lot of scratches. Did not bother getting a replacement. When I tried to return it they didnt want it so I got stuck having to figure out how to dispose of it since it needs to be disposed of properly.

When I first received this power bank it was amazing. I could get 3 full phone charges out of one charge. However after 3 months it stopped working. I charge it will wait till it says 100% then go to plug in my phone and nothing. I have had a different power bank for 4 years and it is still working great. For this one to stop so soon after purchase is disheartening.

Not sure if the unit would even charge or hold a charge. Once i looked at it, it showed 48%, then a little later showed 98%, then 15 minutes later it showed 88%. However, it WOULD NOT charge my phone, therefore it's useless. What a waste of time and energy. Don't believe all the positive reviews like I did. Piece of crap. Made in China of course. I returned it.

Would have gotten 5 star but. I purchased this thinking both outputs were 2.1a as the photo in the description shows. Unfortunately 1 port is 2.1a other is 1.0a. At least it came with 60% charge.

returned this, it was much larger and very heavy, not something i would want to carry around in my purse for a portable charger.

works so great had to buy another.... does take very long to charge but charge also last a few days

I just took it out of the box from shipping and plugged in the cord to charge it and it pushed the screen down and won't turn on. 30 minutes and it's already broke.
