Many of us rely on our iPhones to get work done every day. Your phone is not going to be very helpful when it is out of battery juice. There are plenty of decent battery extenders and chargers on the market. But not too many of them allow you to use regular AA batteries to charge your device. The Oivo is different. It is a compact battery charger that recharges your phone quickly. All you need to do is open the two magnetically connected halves, connect your phone to the Lightning connector, and add your AA batteries.
The Oivo can be carried with your keys. It lets you charge your phone and talk at the same time. The Oivo recharges your drained battery as quickly as a regular AC charger with 1 amp. It has an impact resistant and splash proof design. It does have magnets but they are safe for your phone and credit cards. The Oivo has been developed under the Apple MFi (Made for iPhone) program. This is another interesting Kickstarter project.
