Portable Charger, Vinsic 20000mAh Ultra Slim Portable Charger, 10 Times for iPhone 5/5S, Dual USB Port 2.1a & 1a Portable External Battery Charger for iPhone, iPad, Samsung Galaxy, Cell Phones.

Carry power bank with us when traveling. Lots of power and lasts for many recharges of our cell phones. Like ease-of-use. When necessary, unit recharges over night and ready to go next morning. Nice thin design. Digital readout of remaining power in unit...100% to 0%

I use this power bank quite often, especially when I am on the road and it is an excellent power backup for me. I highly recommend it to everyone.

Awesome power bank. Charges my iPhone 6 Plus several times. However, it does take a long time to charge. Recommend to charge over night.

Vinsic support is very responsive and very kind. Vinsic is quality oriented and they give more importance to the customer satisfaction.

I use it all the time for my iPhone6 and Tablets. Charges units very fast and gives you the assurance of regulated voltage and knowledge that it will not overcharge your units.

Does the job well. Heavy. Not for carrying about.

Bought for girlfriend, and although bigger than expected, very good device. Seems to be very close to the claim of 20000 mAh. She is happy, so I am as well. Directions would have been a nice addition though.

A bit too heavy but works great. I take this with me on the road so I wish it was smaller, but it works great and is pretty.
