완충이 - 보조배터리 공유 서비스

A secondary battery rental service that can be easily borrowed and returned with a QR code.

'Buffer' is a battery that you can rent quickly anytime, anywhere, if you want, and simply return it without using the APP after charging.

You can also check the rental return information in advance on the map.

From now on, when you need charging, look for 'Buggy' around me.
