I think that we can all agree that an external battery pack is really expected to do one thing – charge stuff. I can say with the utmost certainty that the iBattz Battstation Tough Dual Pro 12000 mAh does that with aplomb. With 12,000 mAh of portable power, this spare will charge your devices far longer than many other portable batteries on the market. With that out of the way, I feel that it’s probably more beneficial to discuss some of the things that set the iBattz apart from it’s competitors.
