I wanted to ask if the standard equipment of "T21P E2" includes the power adapter, as I find some suppliers which say that power adapter is not included and I wanted to understand if that's always the case or not.

Also, since I have many unused power adapters from old "T20P" and "T22P" phones... are they compatible with "T21P E2"?

Dear customer,

​This is Aishion from Yealink technical team, nice to know you. My pleasure to work for you!

The Power Adapter standard equipment of "T21P E2" is optional since this model support POE feature, you can order PSU or not.

The unused power adapters from old "T20P" and "T22P" phones are can't work with "T21P E2" since it's different output standard(larger output may damage the phone itself), you can kindly see below:

T20P or T22P: AC 100~240V input and DC 5V/1.2A output

T21P E2: AC 100~240V input and DC 5V/600mA output

For more information about T21P E2, please kindly refer to below datasheet:

​Any question, please feel free to contact us.

Best Regards

Aishion
