至于安卓手机,充电宝是最佳选择。带有小型USB线缆的AmazonBasics Portable Power Bank充电宝提供2000毫安电量,是Wirecutter测试的最佳充电宝,可以和手机一起放入口袋,价格还不到10美元。最适合iPhone的充电宝是29美元的TravelCard,它几乎可以放进钱包里,带有内置式Lightning接口线缆,可以给手机充电。
For Android phones, an external battery pack is a good option. The AmazonBasics Portable Power Bank with Micro USB Cable 2,000 mAh is the best pack the Wirecutter tested that will fit in your pocket with your phone, and it’s less than $10. A great battery pack for the iPhone is the $29 TravelCard, which is almost thin enough to fit in a wallet — with a built-in Lightning-connector cable to charge your phone.
如果要用好几天,如果你需要重复给手机充电,或者有一个大的平板电脑和一个手机出差,Wirecutter推荐Anker PowerCore 15600。它能存储足够电量,为一部普通智能手机充电5次,为iPad Air之类大型平板充电两次,价钱低于40美元。
For days of smartphone power, the Anker PowerCore 15600 is the Wirecutter’s pick if you need to charge a phone repeatedly or keep a full-size tablet and phone topped up through a busy week. It has enough available power to charge a typical smartphone five times or to fill a large tablet such as an iPad Air almost twice — for under $40.
