10000mAh Triple USB Outputs Slim Power Bank Ultra Thin, Mini Portable Charger External Phone Battery Pack Small Dual USB Outlet, Emergency Phone Power Backup

I was pretty amazed that after charging this battery and using it two months later and still held a wonderful charge. Plus it quickly charged my phone. And seemed to charge my phone 4 times without me having to recharge it. I like its slim profile also. Good price. Using it often as my phone loses battery power. It's so convenient with my old iphone which loses battery power faster than you can blink an eye.

Perfect size. Easy access to the ports. Lots of charge. The only drawback is that it's slightly heavier than I would have wanted. Otherwise, an excellent travel item at a good price.

Pros:The plastic shell appears to be a high quality, thick, and rigid material.The device does not creek or flex, and feels very solid.When charging, the battery does not become hot (in-fact, I haven't noticed any change in temperature.)There are 4 ports in total, on the front there are two USB-A ports (output only), and one USB-C port (output / input).To the side you'll find a Micro USB-B port (input only).The inlet and outlet ports have tight connections, so you won't need to worry about disconnections if you'll be carrying the charger in your pocket whilst charging your devices.Cons:The ATTOM TECH logo on the front-side is slightly crooked.Completely quit working after 28 days of use. Returned.Update: In order to apologize for the inconvenience, the seller has decided to send a replacement battery free of charge. Thank you!

Bought 4 of them they are not as thin as advertised but they can charge my phone 0 to 100 3 times but when charging my phone I have to click the button about every 10 min to keep it charging or else it stops the charging process or if I just want to use it to power something for a set amount of time i still have to click the button every 10 min to turn it back on which get very annoying

I like the battery capacity and it’s sleek slim compact design. Very comfortable.

I didn't look at this product close enough. It doesn't have a digital display so it hard to gauge times usage and charging power for various devices. Will be returning to Amazon

We purchased this for our teenage daughter. She has had it about 2 weeks. She likes the way it fits in her jeans pocket and the convenience of being able to take it with her. She appreciates it's long battery life and that she can two whole phone charges out of it. Her only problem with it is that it charges her phone more slowly than she would like for it to.

This is a good option if your looking for something cheap and durable. But the battery doesn’t last too long so you can only rely on it too boost your battery alittle bit. I would find something better if I need to use a power bank often.
