myVolts 16ft 18V 500mA Doorbell Transformer Cord

SKU CH-VXD4-KMFSR

A 16.4 ft power cord delivering 18 V 500 mA AC to keep compatible video doorbells continuously charged without battery removal

  • Keeps doorbell charged without battery removal via 18V 500mA continuous power
  • 4 ft cable reaches distant outlets for flexible installation
  • Wire-ring terminal secures connection without complex wiring or tools
  • Compatible with Ring, Nest, Arlo, Eufy and SimpliSafe video doorbells
  • No resistor required for simple plug-and-play setup

Purpose and fit

The myVolts 16ft 18V 500mA Doorbell Transformer Cord supplies continuous AC power to compatible video doorbells so the internal battery never needs removal for charging. It suits homeowners who want uninterrupted recording without the routine of swapping or recharging a battery pack.

Installation notes

The cord terminates in a wire-ring connector that screws directly to the doorbell terminals, allowing a tool-free connection in minutes. The 16.4 foot length reaches most interior outlets, though routing the cable through tight door frames or across exterior siding may require additional clips or careful planning to avoid pinch points.

Power constraints

The adapter accepts 120V 60Hz mains input and delivers a fixed 18V 500mA AC output, so it cannot power devices that require a different voltage, a higher current rating, or DC input. The 500mA limit also means it will not support doorbells or accessories that draw more current than the rated output.

Questions about this item

How can I confirm the adapter is delivering the correct 18V 500mA output after connecting it to my Ring Video Doorbell Pro?

The doorbell should power on immediately and show a steady charging indicator in its app without any low-voltage warnings.

What comes in the package and do I need to buy a resistor or any extra wiring for a Nest Hello installation?

The box contains the 16.4 ft 18V 500mA transformer cord with integrated wire rings; no resistor or additional wiring is required for the listed doorbells.

Should I choose the 16 ft version or is there a shorter cable option for a SimpliSafe Video Doorbell mounted near an outlet?

Only the 16.4 ft / 5 m length is offered, so that is the version to select regardless of mounting distance.
