In short
Yes. Almost every pellet grill needs electricity to run its igniter, auger motor, combustion fan and digital controller, even though the heat comes from burning wood pellets. Most plug into a standard UK mains socket. The power draw is highest for a few minutes while the igniter lights the pellets, then drops to a modest level. Without power, the fire goes out.

Pellet grills burn wood, so it surprises some buyers that they come with a plug. The electricity does not cook the food; it runs the parts that feed and control the fire. That has practical consequences: you need a socket near the grill, a power cut stops the cook, and taking one camping takes planning. This article explains what uses power, roughly how much, and how to run a pellet grill safely outdoors in the UK.
What the electricity powers
Each part plays a role in turning pellets into steady heat. Remove any one and the grill stops working properly.
| Part | What it does | When it runs |
|---|---|---|
| Igniter (hot rod) | Heats up to light pellets in the firepot | A few minutes at start-up |
| Auger motor | Turns the screw that feeds pellets | In bursts throughout the cook |
| Combustion fan | Blows air into the firepot and circulates heat | Throughout the cook and shut-down |
| Controller | Reads the probe and sets the feed rate | Throughout |
| Wi-Fi or Bluetooth module | App monitoring on connected models | Throughout |
How much power a pellet grill uses
The igniter is the biggest draw, typically a few hundred watts for the first few minutes. Once the fire is going, the fan, auger and controller together use much less. Check the rating plate or manual for your model's figures, as they vary between brands and sizes.
Over a long cook, the total energy use is modest compared with an electric oven, because most of the heat comes from the pellets. The wood pellets are the main running cost.
Wi-Fi models add a small, steady draw for the connectivity module, and some keep the controller in standby when switched off at the grill but still plugged in. Switching off at the socket after the shut-down cycle has finished avoids that and is the safer habit outdoors anyway.
Plugging in safely outdoors
Plug the grill into an outdoor socket with RCD protection, or into a socket protected by an RCD in your consumer unit. If you must use an extension lead, use one rated for outdoor use, fully unwound, with the connection kept off wet ground and out of puddles. Avoid running leads across paths where people might trip.
If you do not have an outdoor socket, it is worth having one fitted by a qualified electrician. Many people end up using one for other garden kit too.
Note:Electricity and water do not mix. Use RCD-protected outdoor sockets, keep plugs and leads dry, and have any new outdoor socket installed by a registered electrician in line with UK wiring regulations.
What happens in a power cut
If power fails, the auger and fan stop and the fire dies down. Some grills restart automatically when power returns, but many go into an error state or need relighting, and a firepot full of unburnt pellets can flare when it relights. Follow your manual: usually you empty the firepot before restarting.
On long cooks, a power cut can leave food sitting at a low temperature for a long time. If you cannot be sure how long the food was below a safe cooking temperature, it is safest to finish cooking it fully on another heat source and check with a probe.

Running a pellet grill away from the mains
Tabletop pellet grills such as the Traeger Ranger and Pit Boss tabletop models are popular for camping and caravanning. On a site with an electric hook-up, they plug in like any other appliance within the pitch's limit. Away from hook-up, some owners use a portable power station or an inverter from a leisure battery; check the grill's start-up wattage and the power source's rating first.
If running without mains power is essential, a kamado or charcoal smoker may suit you better; see kamado vs pellet grill. Our best pellet grills guide includes tabletop models, and are pellet grills worth it covers the wider trade-offs.
Frequently asked questions
Can a pellet grill run without electricity? Standard pellet grills cannot. The auger, fan and igniter all need power.
Are pellet grills electric grills? No. They burn wood pellets for heat and use electricity only to feed and control the fire.
Can I run a pellet grill from a power station? Often yes, if the power station can handle the igniter's start-up draw. Check both ratings.
Can I leave a pellet grill plugged in? Switch it off and unplug it when not in use, and keep the plug dry.
