Choiix Power Fort 5.5W Rechargeable Power Backup Battery Pack

The top of the device is black with a clear gloss plastic cover. There is a single button to activate charging and a tri-colour status indicator LED (green for fully charged, amber for discharging, red for almost empty).

The bottom of the Power Fort is covered in a rubberised, ribbed, grey material. It gives the device a certain amount of anti-slip but at 60g there’s not a great deal of friction created. The diagonal sticker has the necessary compliance logos and warnings, information about the input and output voltages and current and a barcode.

At the base of the device are two USB ports. The full size USB port is marked “OUT” and is used to connect your phone (or MP3 player etc.) to the Power Fort for charging. The other is a MiniUSB port and marked “IN”. As you might have already guessed it is this port that is used to recharge the Power Fort’s internal battery. This can be done via computer/laptop USB or by mains adapter USB (as used by most mobile manufacturers).

From the side you can clearly see the curvey top of the Power Fort and how it glossy finish catches the light. It certainly got a few admiring glances when I took it to the office.
