Power your smart home with confidence

The Xwartre UL Certified 24V Thermostat C-Wire Transformer converts a standard 120V outlet into a stable 24V AC supply for thermostats and doorbells. Its 26ft (8m) cable offers flexible placement, helping you reduce clutter while keeping the adapter within reach of your device.

Why this transformer stands out

  • UL certification supports safety and durability in daily use.
  • Overload latch-off, over-current protection, voltage protection, and short-circuit protection guard your equipment.
  • Long 26ft (8m) cable enables you to position the adapter away from the device and toward a convenient outlet.
  • High-quality copper conductors with PVC-coated insulation ensure reliable power delivery with minimal signal loss.

What you power with this transformer is broad and practical. It is designed to work with popular thermostat models such as Nest Thermostat, Nest Thermostat E, Nest Learning Thermostat (3rd gen), ecobee Lite and other ecobee models, Honeywell Home Thermostat, Emerson Sensi, WYZE Smart Thermostat, and many doorbells and related devices that require 24V AC power.

  • Thermostats: helps maintain consistent power to avoid unexpected resets or reboot prompts in typical setups.
  • Doorbells: supports continuous operation for reliable doorbell performance without frequent battery changes.

How to install

  • Power off the system before wiring.
  • Connect one wire to C and the other to R on the thermostat or doorbell side (no polarity required).
  • Plug the adapter into a nearby outlet and power the device back on to verify operation.
