We’ve introduced two iPhone 4 cases with battery packs. Now we found out the third one: Energizer AP1201 PowerSkin iPhone 4 case with external battery.
Similar with other iPhone 4 cases integrated rechargeable batteries, Energizer AP1201 PowerSkin also has a built-in rechargeable battery, yet it features “smart” battery technology. Through LED indicator on the back of the case, you can clearly know the power status. Two charging options allow you to make a choice between high speed and pass-through charge modes.
According to Energizer, the built-in rechargeable battery can provide up to 200 hours of standby time, 27 hours of music time, 7 hours of video time, or 5 hours of talk time or Internet time.
Apart from that, the case is made from recycled silicone rubber. Apparently this kind of material can effectively prevent the iPhone 4 from some shocks and scratches. And an integrated bumper can help you address the reception problem of iPhone 4.
Energizer AP1201 PowerSkin iPhone 4 case is priced at $79.99 USD. If you’re interested, jump to its official site for more details. Additionally, don’t forget to check other two similar cases including Mophie juice pack air case and the unknown iPhone 4 juice pack.
