we recommend using a good quality 5W power adapter with all of our devices that charge over usb. to charge OP-1 use the included usb-mini cable and connect it to a computer, or usb charger. please also ensure to use a high quality charging cable such as the one included with your device.
your unit will charge when:
- it is turned off and connected to a usb power source. (computer / charger)
- it is turned on and connected to a usb power source, unless usb charging has been turned off in the OPT menu. (shift + COM, T4)
- it is in TE-Boot menu and connected to a usb power source.
a spare usb-mini cable can be ordered here.
