Sony just introduced its new line of external battery packs aimed at smartphones and tablet computers. The capacities being introduced range from 3,500 to 7,000 mAh which should be enough for even the power users. The boxes which weight about 189gms and measure 130.6mm by 12.9mm ensure that the smartphone sized batteries can fit in your pocket.
The folks atHyperMac sent us the HyperMac Micro for review. The device serves as a portable charger for the iPhone and iPad. This is one of the most attractive devices we have seen and it does not look like a battery at all unless you get really close. On the inside it packs a 3600mAh battery which promises to recharge your iPhone 4 upto 3 times. It also works with the iPad but only extends the life by about 5 hours. That’s fine because the iPad packs a monstrous battery which won’t event charge via normal USB port. We are more interested about how this device works with the iPhone and it worked pretty well.
