Will this work if plugged into 220 electric or will it burn it up

The unit is powered by an AC to DC adapter. It's rated for 100-240VAC input with a 12VDC 1.0A output, so I assume it will work fine on 220VAC.

Can it connect to TV as an input via Bluetooth?

In theory you can buy a Bluetooth transmitter and receiver with the proper input & output cables. Lotsa wires though, defeating the purpose of wireless =:-)

When connecting to phone via Bluetooth can you still hear sound via phone? Needing to use while on zoom calls. But use mic to not have to phone in han

The Bluetooth of the microphoneIt can only played Music and audio files. Telecom calls and third-party app calls can not be used with microphone.
