| Bottom line | The iPhoneck Backup Battery is easy to use and it works as promised. We just wish it had a sturdier construction. | The Backup Battery is a well-designed and functional solution for delivering emergency power to your iPhone. | The MyCharge Peak 6000 is sort of the Swiss Army Knife of portable battery chargers, with built-in connectors for iOS products,
Android devices, and a host of other products. | The Richard Solo 1800 Backup Battery is on the expensive side, but you get a lot of bang for your buck. | Lightweight, quick, and easy to use, the i.Sound Portable Power Max battery is a great way to keep your USB gadgets going when a wall charger isn't accessible. |
