Very useful for power hungry S4s,
Verified Purchase(What is this?)
This review is from: Samsung Galaxy S4 Extra Battery Kit - White (Wireless Phone Accessory)
This is a very useful addition to your power hungry Samsung S4.
It takes the standard micro USB charger (NOT SUPPLIED)
It comes with a spare larger S4 battery so no need to buy a battery separate to this.
It is small enough to pop into a pocket or purse as it is not much larger than the battery itself.
