This is a power bank, you see my phone is dying, and I don’t have a phone charger with me now, so I have to go scan a portable power bank, this is really convenient .
    You san the QR code, and the power bank will automatically come out, now I can get my phone charged.

    这是充电宝，你看我的手机快没电了，而且我现在没有手机充电器，所以我必须去扫描移动电源，这真的很方便。
    你扫了二维码，充电宝会自动弹出来，现在我可以给手机充电了。
