To ensure optimal processing speed, make sure your card reader is always at least 25% charged or higher. We recommend charging it on a monthly basis, even if you don’t use your SumUp Pro Card Reader regularly.

Charge the SumUp Pro Card Reader using the USB type C cable included in the packaging by connecting the cable to a computer, or another power supply. You can still use your standalone SumUp Card Reader while it’s charging.

You can view your battery level on the screen of your reader and via the LED on the card reader (see LED lights for more information).
