Powerknots keeps an arsenal of backup batteries ready for your powerless friends

20140819083204-imageSmartphones have dramatically increased in versatility over the past 10 years, but that tends to keep battery life a constant struggle. Many people have long cursed the their weak capacities, leading TechSquare to create PowerKnots. Their design holds massive power: each bite-sized block has a capacity of 5200mAh and each station can charge up to eight, allowing a user to have up to 41,600mAh of power at their disposal. A smartphone user (or anyone else wanting to charge something) with PowerKnots is guaranteed to not stare at a dead phone for a very long time. While it’s probably overkill for most folks, it might make sense for those signing up for the smartphone family plan. You can get started in December 2014 with a four-pack and charging station for $70 among other more expansive options.
