This turned out to be quite a handy device to have this winter. During the numerous power cuts we had due to the 94mph winds I was able to keep my HTC Sensation XE phone charged long enough to last until i got to civilisation. The Portable charger actually charged my phone to 100% ( I turned the phone off while it was charging) doesn’t seem to take as long! So this portable charger basically doubles the phones battery life when your out and about away from mains power.
It works by plugging the unit into the mains power to charge up, there are LEDs on the front that let you know when its full. You can remove the 3pin mains plug and just carry the battery unit when your away to save space, but just dont forget the usb charging cable for your phone. Just plug your phone into the unit and it will start charging. Quite handy if your on a long day out and have been using your phone a lot, for example when I travel i tend to listen to music all the time and use the phone’s features so that drains the internal battery a lot. But with this unit I can extend the useage time plenty to get me to where I am going without going flat. Just remember to charge the portable charger first before venturing out! 🙂
