No more dead batteries or mid-day outages when someone rings, giving peace of mind for busy households. Is an 8-metre plug-in supply the right long-term power solution for your Ring or Nest camera?
⚡ At a Glance
- • Power Output: 24V AC at 500mA for continuous charging of compatible doorbells and thermostats
- • Best for: Owners of Ring, Nest, Ecobee and similar smart doorbells and thermostats needing constant power
- • Not ideal for: Homes that require in-wall hardwiring or lack a nearby mains socket
Compact plug-in transformer supplies a steady 24V/500mA AC output through an 8-metre cable. Compatible with Ring, Nest, Skybell, Ecobee, Honeywell and many thermostats for continuous operation.
Reliable continuous power - with 24V/500mA AC output
A rated 24-volt AC output at 500 milliamps supplies a steady current suitable for many video doorbells and smart thermostats. Constant AC power avoids repeated battery charging cycles.
Continuous supply prevents 'low battery' interruptions and keeps cameras and thermostats operational without battery swaps.
Flexible placement and neat routing - with an 8-metre cable
An 8-metre (315-inch) cable reaches distant sockets, allowing the plug-in supply to sit well away from the doorframe. Cable terminates in two copper wire tips for direct screw-terminal attachment.
Long cable means indoor or outdoor sockets can be used, avoiding the need for new wiring or bulky extension leads.
Safer long-term use - with short-circuit and overload protections
Circuit safeguards and material choices reduce the risk of short circuit, overvoltage, overcurrent and overheating during continuous operation. Conductive materials aim to maintain stable transmission and prevent faults.
Built-in protections help protect connected doorbells and thermostats and reduce the chance of damage during prolonged use.
