For 9 quid the Portable Power backup battery represents extremely good value, and Powermat belongs to a world-leading technology group Duracell - a reputable battery producer! Put it this way: a decent battery charger for your iPhone or HTC smart phone can easily cost you the same, but this Portable Power not only charges your smartphone at home or office, it is also an emergency backup battery which can power and charge your smartphone when the phone battery exhausted! The fully charged capacity of 1850mAh is around 30% more than the standard battery for iPhone 4S battery (or 20% more for HTC Desire, or 40% more for Blackberry Torch)
In addition, the Portable Power also function as a Receiver of a Powermat wireless charger. If you are not familiar with Powermat wireless charger system, you only need to know that a Powermat Wireless Charger contains two parts: one Mat/transmitter (not included) and one Receiver, and the Receiver attaches to your smartphone (or other gadget) to charge its battery. A 3-position Mat costs around 10 quid which can support 3 Receivers (charges up to 3 devices simultaneously), if you have multiple portable gadgets then it is clearly wise to buy one Mat than to buy multiple chargers. However if you don't want to spend more money on a mat now, you can also charge this Portable Power external battery pack by plugging into a computer USB port.
