A smartphone's battery at 10 percent or less can send anybody into panic. However, Jackery Air is a great, portable and extremely thin solution for smartphone and tablet users when they are on the go. This strong external battery features up to five days of additional operational time, in which it can charge a smartphone two to four times. It is also made up of an ultra-light aluminum case, the same aluminum molding process utilized by Apple.

The slim, light design means it's ideal to carry, making it the perfect solution in any battery-drained emergency.
