Lenovo PB500 Power Bank, 10000 mAh, Slim Design, Polymer core, Dual-output USB interfaces, Black, GXV0J50547

I’ve been using this powerbank for more than a few weeks now and I have to say that I am continually impressed by Lenovo’s quality and stamina. I have used this to charge my iPad and iPhone, it has enough juice per charge to power both without difficulty. Most of my laptops are made by Lenovo, so I was not let down. I did think about buying one a few years back, the Bizer model, and should have. I wasn’t going to miss another opportunity especially for the price point. Thanks Lenovo for another quality product.

Power bank fails to recharge when plugged into the power socket. It has become useless.

Amazing charger it will last for 2days charging best i ever tried

Picked one up used and I'm really happy there's a little bit of wear, but it charges, the ports arnt loose and it charges well, happy with it!

Didn’t charge after use

It was to replace one that I’d lostIt works great

Pros:* Simple single-button interface to check charge status.* Provides 2.1A as advertised. Full charge rate with with Samsung Note 5, LG G3.* 10000mAh lasts a long time.Cons:* 4-point LED indicator is a little unclear. After fully charging 3 phones, still shows 3 or 4 segments lit (which I guess means anywhere from 50-100% charge remaining). That seems unbelievably high. If each phone 2000mAh, that leaves 4000mAh out of 10000mAh left in the powerbank or 40%. Should see 2 LEDs lit at that point.

I pulled it out of the box today and attached it to my laptop but the laptop never charged. Instead, the laptop eventually died on me. I am contacting the seller for a refund or replacement.
