iBattz Mojo Battstation Tough Dual Pro
Available in either 7200mAh or 8400mAh configurations, iBattz' Mojo Battstation Tough Dual Pro ($30-$40) batteries are universal charging solutions at unusually low prices. Each plastic battery is the same physical size, and comes paired with a ruggedized rubber skin, designed to withstand impacts. Included in a package are a Micro-USB cable for charging Battstation's battery, as well as two Dock Connector tips for use with legacy Apple devices; those with newer iPads, iPhones, or iPods will have to provide their own Lightning cables. The batteries' two charging outputs only support 1A and 500mA charging, respectively, so it'll take quite a while to recharge an iPad; still, these are amongst the least expensive battery packs we've seen in recent times.
