Belkin’s new Pocket Power banks pack 5,000 or 10,000 mAh into elegant black, rose gold and silver-coloured packs that are lighter and thinner than their predecessors.

They feature new polymer battery cell technology, fashion colours, and built in safety features.

“With the smartphone becoming even more essential in people’s lives, not just as a means of communication, but as a camera, music player, navigation system, and Internet-access device, preventing low battery on-the-go is even more important for consumers than ever before,” said Marco Peters, vice president of product management.

A typical smartphone will use about 3,000 mAh so the 10,000 mAh pack will provide up to three charges. To put this in perspective that’s 19 hours of extra talk time or 25 hours web browsing.

The Belkin Pocket Power 5,000mAh costs $39.95 and 10,000mAh costs $59.95 and are available from Belkin  as well as leading retailers, including JB Hi Fi, Harvey Norman, Myer, Big W and more.
