Description
Temperature Controlled Extension Cord for 120V Heaters
This MAXKOSKO extension cord with thermostat automatically turns compatible 120V heating devices on near freezing and switches them off after the temperature rises. The preset extension cord thermostat requires no programming, app, or permanent wiring.
Choose a 1-to-1, 1-to-2, 1-to-3, or 1-to-4 outlet configuration. All outlets on a multi-outlet model operate together under the same thermostat control.
Automatic Freeze Control
Typically turns connected heaters on near 37°F (3°C) and off near 50°F (10°C).
Multiple Outlet Options
Select 1-to-1, 1-to-2, 1-to-3, or 1-to-4 based on how many compatible heating devices you need to control.
Clear Status Indicators
The 1-to-1 model has one indicator light. The 1-to-2, 1-to-3, and 1-to-4 models feature dual indicator lights.
Slim, Plug-and-Play Design
The flexible 20-inch cord helps reduce plug crowding and requires no wiring or temperature setup.
Important Before Ordering
Preset Temperature: This mechanical thermostat is not adjustable and may show small normal variations in switching temperature.
120V Heating Devices Only: Use only with compatible heating equipment that can safely restart when power is restored. Do not use with cooling appliances, compressors, whole-home HVAC systems, or 240V devices.
Check the Total Load: On multi-outlet models, the combined load of all connected devices must remain within the ratings of the controller, wall outlet, and electrical circuit.
Protect Every Connection: Keep the plug, outlets, and all electrical connections dry and protected from rain, snow, and standing water.

Setup & Placement View Steps Hide Steps
1. Check Compatibility
Confirm the heating device is 120V, within the safe load, and suitable for automatic restart.
2. Connect the Controller
Plug the temperature controlled extension cord into a suitable 120V outlet.
3. Connect the Heater
Connect the heating device or devices. All outlets on a multi-outlet model switch together.
4. Position and Protect
Place the thermostat where it senses the actual cold area, and keep every electrical connection dry.
Placement Matters: Keep the thermostat away from direct sunlight, insulation, standing water, warm pipes, heating cables, and other heat sources that could cause an inaccurate temperature reading.
Frequently Asked Questions
At what temperature does the extension cord thermostat turn on and off?
It typically turns connected heating devices on near 37°F (3°C) and off near 50°F (10°C). Small differences are normal with a mechanical thermostat.
Can I adjust the activation temperature?
No. The on and off temperatures are preset. Choose an adjustable digital thermostat with a remote sensor when your application requires a specific setting.
What is the difference between the 1-to-1, 1-to-2, 1-to-3, and 1-to-4 models?
The first number represents one power plug, and the second shows the number of thermostat-controlled outlets on each unit. All outlets on a multi-outlet model switch on and off together.
Do all models have dual indicator lights?
No. The original 1-to-1 model has one indicator light. The 1-to-2, 1-to-3, and 1-to-4 models have dual indicator lights for easier status checks.
Is this a heated extension cord?
No. The cord itself does not generate heat. It is a temperature controlled extension cord that automatically supplies or stops power to a compatible heating device.
Can it be used outdoors?
It can be used in protected outdoor applications with a suitable outdoor outlet and weatherproof in-use cover. All electrical connections must remain dry.
