5.0 out of 5 stars
Impressive for power users, 17 Dec 2013
Just received my Anker battery case for iPhone 5/5S. Having a good experience with the Anker battery backup I purchased earlier, i decided this would be great as soon as I saw it announced.
Right out of the box, it started to impress. There are two outer bumpers supplied, smoke or clear, plus the battery back and micro USB charging/sync cable. The first thing I noticed was how lightweight it is; I even checked inside the box to see if there was a separate battery. The profile is so slim it is surprising they built a lithium battery into it. There was no problem with installation, I didn't bother with instructions. You just slide your iPhone into the battery back and onto the Apple Lightning connector, then snap on the outer ring shell. The precision fit is perfectly integrated into the design of the phone. It adds about a quarter inch in length at the bottom and is barely thicker than the regular case I had on previously. There are two speaker ports at the bottom allowing sound to come through, slightly changing the tone, but not in a bad way. Activating the power to add charge to the phone is accomplished by pressing the button on the back for three seconds. Tiny LEDs show how much charge remains. The familiar iPhone beep sounds and the charging icon appears in the top corner of your screen, just as if you plugged into an outlet. I can go from 33% to a full charge while the LED charge indicator on the battery case remains nearly full. This is perfect for travel or long work days when I don't have time to think about plugging into a wall, car charger or external backup battery. It's also one less accessory to carry or hunt for when needed, exactly what I wanted. This is suited for heavy power users of apps, maps, videos or games, to keep us going without interruption all day long.
The supplied micro USB cable syncs and charges the phone. This means you no longer need to use a Lightning cable, just the generic micro USB cord also used by other smartphones phones and devices. Replacement or spares cost only a couple of pounds compared to buying another expensive Lightning cable.
