Keep your USB-powered devices charged while on the go with this myCharge RazorPlus RZ30G-A power bank, which offers up to 13 hours of additional talk time on most smartphones. The 3000 mAh capacity lithium-polymer battery comes precharged for simple use.
I needed a portable charger for my Samsung Galaxy s6 phone and had purchased a less expensive one. It did not charge my phone so I returned it and got the Razor Plus on the recommendation of a Best Buy employee. It works great and is small enough to carry in my purse. And even better, it was on sale when the cashier rang it up! I would recommend it if you are looking for a medium priced power bank.
