Two Notes Revolt Power Supply Question

[Augustwest0218]

I am looking to use the Revolt portably, and was wondering if the Revolt can be plugged into an ungrounded outlet safely, as I know that it's a bad idea with amps, but unsure if the ground is there to reduce noise or safety with this device. Thanks!
