Modern day life has brought with it some amazing technological advances (that’s kinda what this site is all about), but also a few headaches. Maybe the biggest of them all? Battery life. The Bolt portable charger ($60) aims to ease your going-juiceless concerns with what they say is the world’s smallest combination wall charger/battery backup. Even though it’s tiny, the makers say it will still fully power-up most smartphones two times before needing a breather, and the lithium-ion battery inside Bolt promises to withstand a minimum of 500 full cycles.
