现在市面上有很多智能手机的外置电池，一般用户在选择外置电池时，会从两方面的因素进行考虑：容量和设计。新推出的名叫Jackery Air的外置电池正好能满足这两方面的需求。

 

    这款电池的厚度只比iPhone 5稍厚一点，设计美观、线条流畅，其与iPhone同样大小的尺寸意味着这款电池也能像手机一样随身携带。5600mAh的电池容量，虽然不是最大的，但鉴于如此轻薄的外观设计，这么大的容量已经足够了。

 

    从零电量到充满，Jackery Air需要花费6个小时，但它号称能将iPhone以及其他智能手机的电池寿命提高200%，而且还适用于大一点的如iPad这样的平板电脑。目前这款外置电池处于短期促销阶段，只需80美元，就能拿到一款持久耐用的外置电池，摆脱经常低电量的阴影。

 

    An iPhone-Thin Battery Perfect For Charging Your iPhone's Thin Battery

 

    There are almost as many external battery pack options for your smartphone as there are cases, and given the multitude of options there are probably two important factors to seriously consider: capacity and design. And a leading contender for both these considerations is the new Jackery Air.

 

    The battery measures in at just slightly thicker than the iPhone 5, but its contoured housing and similary-sized dimensions means it can slip in your pocket as easily as your phone. And while the Jackery Air's 5600mAh isn't the largest you can buy, it's certainly capacious enough given the back battery's slim form factor.

 

    Charging it from dead takes about six hours, but it promises to then boost the battery life of your iPhone or smartphone up to 200 percent and it can be used with larger devices like iPads and other tablets. It's on sale now for $80 for a limited time, making it a pretty reasonable way to never have to deal with a low battery warning ever again.
