I took a chance to buy this battery instead of Anker oo Jackery because of the design.After checking its website, it make my decision easier. Received today and tried on my ipad and iphones 5s.Bingo, no problem. After 2 full chargers,still has a lot of juice for my ipod. It has cute cover to protect the USB from dirt.Comes with Micro USBcable & iphone 4s tip.Will recommend my friend to buy it. Thanks Charzon.

Works like a charm. I Phones are notorious for their batteries dying quick. The back up battery pack is great to carry around in my pocket.

Enjoying using this powerbank. Seems to work exactly as described. I have had zero issues to date.

It is the second I buy.

I own the excellent Charzon Amadeus bluetooth speaker, so I thought I would give their power bank a try. Another outstanding product by an up and coming company. I have owned many power banks rated at 5600mAh and 8800mAh, yet none of them charged my iPhone 5S more than 1-1 1/2 charge. The Charzon Fast charges my phone twice and then some on is 5200mAh rating. WOW!!! Now I know that a quality battery DOES make a difference. Give these guys a try, I don't think you will be disappointed. And the fit and finish is just high quality compared to the other offerings on Amazon.

Just received this as a gift. It charges all my devices and the battery is really 5200mah. It lasts much longer than my old charger. I am getting some for the kids.
