Works with mobile phones, Bluetooth headsets, PDAs etc.
You can charge the charger and the device from the same USB socket
Provides around two recharges or a mobile phone or up to 10 recharges of a Bluetooth headset
Much smaller and lighter than a mains charger
No indication of how much charge the portable charger has left
It isnt a second battery for your device but rather a charger for your battery
