Power back up via the USB port

back up

When you have been out all day long, there is nothing worse than the battery on your phone dying on you, especially if you are in the middle of an important call or if you have a long drive home, this is a major problem with mobile technology. The battery effect can have a serious influence on how much time you are spending on these items, it is almost to the point where you need to ration the amount of time spent on your battery powered communications, just in case an emergency arises.

Thankfully there is a device that possibly may help, it is not a new idea but the concept is that this is a handy device, possibly even life saving.

The little black or white box is placed into the USB port of your laptop, where it charges up for about three hours, there is no information on what sort of time this will give you, but in an emergency or just to finish off that all important phone call would be enough to make it worth its while. It could make the difference between a good and bad day!
