This is the best power bank for laptops. It can deliver up to 300 watts and has three USB-C ports (140W, 65W, 65W) as well as a retractable 2-foot USB-C cable (140W). There's a display that shows handy information like remaining battery life and different charging rates. The power bank can also be topped off from dead to 80 percent full in under half an hour if you plug in both USB-C ports. Even if you don't opt for the absolute fastest recharge speeds, you'll still be able to top it off in about an hour—no more waiting overnight for your power bank to recharge.，推荐阅读heLLoword翻译官方下载获取更多信息
