Nest Cam Wired 2nd Gen. Can I power my Nest Cam from a 12v to 5 V DC Cigarette style converter

Community Member

I have a boat that I wish to put my camera on, it has a 12 V DC plug in power socket like a cigarette type.

I have a 12 to 5 V USB plug in converter rated at 2.4A

Does anyone know if this is safe to power the USB plug on the Nest Cam and also the load that the camera needs to work ?

Thank You

Hi there, 

Sorry to hear you're experiencing this, as I can imagine it has been an inconvenience. I would love to look into this further for you. The Nest Doorbell (wired, 2nd gen) must be connected to a transformer rated to 16 to 24V AC and at least 10 VA to receive enough power. 30 VA is recommended for homes that have high-impedance doorbell wiring due to long wire runs or thin doorbell wiring. You may need to upgrade or replace your current transformer. You also need to replace your current Nest chime connector with the new one that comes with the Nest Doorbell (wired, 2nd gen). For more information, check this article.
