BDL-0052U (2x BAT-0052 + CHR-0085)
Our Samsung Galaxy S4 Replacement Battery charging kit comes with two standard S4 batteries for the S4 as well as a FREE universal battery wall charger that charges one battery externally while you charge the second phone via USB.
That way you can double your Galaxy S4's battery life without the added bulk of an extended battery.
Having a backup spare battery for the S4 means you can stay charged all day without having to be tethered to a phone wall charger.
