The Safest Battery Case for Your iPhone Our grade-A lithium-polymer battery is certified by MFi, CE, FCC, and RoHs; comes with smart circuit protection; and has no possibility of exploding (unlike Li-ion batteries, which may explode under extreme circumstances). All of this is to ensure that the battery case can be used safely.

Innovative Design The clever design solves four major issues: difficulty in application, hard-to-reach controls, a recessed headphone jack, and reduced sound quality. 3-in-1 Battery Case (Charging, Data Transfers, and Protection) The industrial-grade plastic used protects your iPhone from bumps and scratches, while the micro USB cable included allows you to transfer data while charging your iPhone as well as to charge both your iPhone and the battery case at the same time.
