OTII-ARC-PRO does not come with a power supply. Though here is the response we got back previously on this question:
“Connect your Otii Arc/Ace to your computer using the bundled USB-cable. Use a PC USB port with a Charge marking if possible. This indicates high power, and the port may provide up to 1.5A to your device. USB ports without this sign can normally provide up to 500mA."
Note: The current provided by the USB port is used to power both the Otii Arc/Ace and your device.
