Nest - AC adapter wire question

QUESTION — I have three Nest thermostats - two work great - they only control heat. My third Nest controls heat for the second floor and the whole home AC. This Nest is constantly losing battery during the summer. The heat and AC are separate units and the wiring to the troubled Nest is the following;

Heat white wire — W1

Heat red wire — RH

Air red wire — RC

Air green wire — G

Air white wire — Y1.

I’m hoping an AC adapter will fix my constant low battery problem in the summer.  What wiring changes do I need to make to hookup the AC adapter??  Thanks.

You can use the official power connector (https://store.google.com/product/nest_power_connector?hl=en-US) , wiring it in is a snap!

Thanks for the suggestion - I already have the AC adapter, and I don’t think my heat source- Navien combi boiler is compatible with the Nest power connector.
