The Mobius features:
- A lithium-ion battery
- Monocrystal solar panel
- Battery charge indicator and solar charge indicator
- Wide holes to keep all the buttons, ports, and camera unobstructed
Eton claims the battery is large enough to double your iPhone’s runtime. And at 4 oz., it won’t weigh you down. The snap fit design makes it easy to take the Mobius case on and get it off without damaging the glass.
