Boost Bank 2 IN 1 PRODUCT: 12 V Car Charger AND Power Bank in Black - Has 2 USB ports for charging smartphones and tablets - Also is a portable back-up battery pack with 2200mAh capacity battery for charging all smartphones (Apple, Samsung, HTC, Nokia, LG, Sony, etc)

Great, and almost as advertised, but it should be noted that the one I received differed from the advertised specifications in the following:No micro USB cable was includedBoth outputs are described in the literature as being 1A. Neither is 2.1AI like the charge remaining indicators on by the USB sockets - useful to know how much is left in the built-in battery. It happily charged my iPhone and another device simultaneously. It would have been 5* had it actually been as advertised.

Great idea to have a car charger and power bank in one product. High quality and works well. When used as a power bank it can fully recharge my iPhone 4S. Highly recommended.

I've had problems in the past with car chargers that interfere with the radio in my car and causes distortion. Not this one though as it seems really well shielded.

It is good.
