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.
The MiPow Power Tube design is similar to that of Sanyo Eneloop Stick Booster KBC-D1BS which my mom’s business friend got it for me from Japan.
According to iPad 2 Wi-Fi Teardown, iPad 2 battery has a capacity of 6,930mAh which means the MiPow Power Tube 6600 can almost fully charge the iPad 2 on a single charge.
On the other hand, based on iPhone 4 Teardown, iPhone 4 has a battery capacity of 1,420mAh and hence the MiPow Power Tube 6600 can charge an iPhone 4 a total of 4.5 times on a single charge.
