Yes, as long as it is a shared power bank of the same brand. Roughly speaking, there are four steps to renting a shared power bank.
The first is the code scan. This requires the phone to keep a little charge. Complete registration by scanning the QR code on the rental cabinet. This screen will direct the user to the payment screen. After payment, you can borrow it. In general, this kind of rental is the most free. After taking out a loan here, the user can move freely. Even if they go somewhere else, as long as there is a corresponding rental counter, they can return it, which is similar to sharing a bike.
The other is a fixed location. Users can not move, can not be used with charge, flushing can not be returned on the spot.
Some businesses also offer free emergency fees, but for a slightly shorter time.
You can't. Every power bank you borrow has to be returned, because it's all numbered.
