My Hong Kong cousin gave me the MiPow Power Tube 6600 (online store) which is retailing for S$125. It boosts a battery capacity of 6,600mAh and is made from aluminum case with durable anodized colors.

The package includes charging tips for iPad/iPhone/iPod, Blackberry, HTC, Motorola, LG, Sony Ericsson, Samsung, Samsung Galaxy, PSP, Nintendo DSL/DSi/3DS and Female USB.
