Which smart plug for kitchen appliances like a coffee maker or kettle?
Updated
Check the plug’s 15 A / 1,800 W rating, the appliance’s watts and whether its switch stays on. Many kitchen appliances should not be started or left running unattended.

Step 1: Read the label and do the math
Kitchen appliances draw far more power than lamps or chargers. The Department of Energy’s example for an electric kettle is 1,500 W, taken from the label. Divide watts by 120 volts to get amps: 1,500 W is 12.5 A. A standard 120 V outlet circuit is 15 A or 20 A, and a plug rated 15 A covers 1,800 W on paper. That leaves very little headroom for a kettle, which is why many smart plugs list lower ratings for heating loads or motors.
Read the plug’s rating plate or listing for both amps and watts, and whether the rating is for resistive loads (heaters), which are easier on the relay, or for general loads. If the listing gives no amps at all, it is not a plug for a kettle. Look for UL or ETL listing on the plug.
Step 2: Does the appliance work with a plug that cuts and restores power?
A smart plug turns the wall power on or off. The appliance has to start by itself when power returns.
| Appliance | Works with a smart plug? | What to check |
|---|---|---|
| Drip coffee maker with a rocker switch that stays on | Often yes | Switch must remain on when power is cut; auto shutoff; keep to the label wattage |
| Coffee maker with a touch panel or clock | Often no | The panel resets when power is cut and waits for a button press |
| Electric kettle | Usually no | The lever clicks off after boiling; the plug cannot restart it, and kettles are near the plug limit |
| Slow cooker with a mechanical dial | Yes, with limits | Use it only for the shutoff or timer; follow the maker’s unattended-use guidance |
| Toaster oven, air fryer, rice cooker | Not for starting | High draw and heat; use the appliance’s own timer and stay home |
| Stove, range, microwave, dishwasher | No | Major appliances plug directly into a wall outlet or are hard-wired |
Step 3: Be careful with anything that heats
The U.S. Fire Administration reports that cooking is by far the leading cause of home fires and injuries, and that unattended equipment (37%) was the leading factor contributing to ignition in nonconfined home cooking fires. That statistic is about cooking equipment in general, but it explains the rule of thumb: do not use a plug to start something that heats when no one is home to see it. A smart plug is a convenience for a coffee maker you set up the night before and fill with water, not for a skillet or a toaster oven.
The USFA also advises plugging major appliances directly into a wall outlet, never using an extension cord with them, not overloading outlets or power strips and unplugging small appliances when they are not in use. A smart plug counts as an adapter, so keep it in the wall outlet itself, not at the end of a cord or in a power strip, and stop if the plug body feels hot. If an outlet is loose or discolored, have it checked by a licensed electrician before you add a high-draw plug.
Step 4: Useful features for the kitchen
- Energy monitoring. It shows the actual watts drawn, so you can confirm the load before you rely on the plug. Our guide to energy-monitoring smart plugs explains what the numbers mean.
- Physical button. A button on the plug lets you turn it off without the app.
- Spacing. A bulky plug can block the second outlet. Look for a compact or offset design.
- Local control. Matter or Zigbee plugs on a hub keep working when the internet is down.
- Power-loss behavior. Choose a plug that stays off after an outage rather than switching an appliance on by itself.
Where a smart plug does make sense in a kitchen
Lamps, small fans, a countertop radio, a warming tray with a built-in thermostat that you attend and a coffee maker prepared the night before are the usual fits. Also consider whether a plug is the right tool: a stove shutoff device is a different category entirely, and our smart kitchen kit lists the sensors and alerts that add more safety than a plug does.

Can I plug a coffee maker into a smart plug?
Often yes if the plug is rated for the load and the coffee maker has a physical switch that stays on after power is cut. Models with touch panels or clocks usually need a button press.
Can a smart plug turn on an electric kettle?
Usually not. Most kettles switch off at boil and need a lever press, and they draw about 1,500 W, close to a 15 A plug’s limit. Use the kettle’s own features.
Is it safe to use a smart plug with a slow cooker?
Only if the plug is rated for the load and you follow the cooker’s instructions. Don’t start anything that heats when no one is home to see it.
Should I use a smart plug with an extension cord for a kitchen appliance?
No. The U.S. Fire Administration advises not using an extension cord with major appliances and not overloading outlets or power strips. Plug directly into a wall outlet.
