With all these ‘smart’ devices out there, one glaring component has been sorely overlooked in the electronics-with-a-brain category: the charger. Yes, the little thing that delivers your phone’s precious juice has been an afterthought… until now. The Powerslayer is billed as a smart USB charger that intelligently powers up your devices while eliminating energy waste and improving long-term battery performance. Thanks to the embedded software, Powerslayer powers off and on automatically, delivering energy only as needed to protect against over-charging. It’s made in California and they have some pretty smart people there if you subtract the Clippers management.
