Holds a decent charge and is certainly worth the money.

Worked first time, charged ok, and used once

Never works and loses the charge in an hour

My main problem is, this thing loses charge within a day or two, so you can't carry it in your wallet as backup.

like viral lab said it work for me in the first day use but after that no charge to i phone (battery full charge)

But my galaxy s9 shows slow charging

It's held a charge for weeks, and works when I need it.

I wish they would offer a usb c adapter as well

Just as slim and compact as it looks in the pictures

One of them stopped working about three weeks ago, and the other has stopped working as of two days ago
