How Many Watts Does a Toaster Use? Toaster and Toaster Oven Watts
A 2-slice toaster uses about 900 watts and a 4-slice toaster about 1,600 watts. Breville rates its 2-slice BTA820XL at 900 watts and its 4-slice BTA830XL at 1,600 watts, and its Smart Oven toaster oven at 1,800 watts. Because a batch of toast takes only a few minutes, each one uses very little energy.

How much electricity does a toaster use?
Watts x minutes / 60 = watt-hours. A 900 W toaster running for 3 minutes uses about 45 Wh, less than 1 cent at 17 cents per kWh. A 1,800 W toaster oven running for 20 minutes uses about 600 Wh, about 10 cents.
Can a power station run a toaster?
Yes, if its continuous output is higher than the toaster's watts. A toaster draws its full rating the whole time it is toasting.
| Power station | Capacity / output | Runs | 3 minute batches (900 W) | Price |
|---|---|---|---|---|
| Jackery Explorer 1000 v2 | 1,070 Wh / 1,500 W | 2-slice toasters | About 21 | From $499 |
| Jackery Explorer 2000 v2 | 2,042 Wh / 2,200 W | 2-slice, 4-slice, and toaster ovens | About 41 | From $899 |
| Jackery HomePower 3000 | 3,072 Wh / 3,600 W | All three, plus a coffee maker at the same time | About 61 | From $1,349 |
Batches = capacity x 0.9 / 45 Wh. Capacity and output are from each product page. Browse all portable power stations.
Can a generator run a toaster?
Yes. A toaster is a heating element with no motor, so there is no starting surge. A generator like the DuroMax XP5500HX (4,500 running watts, CO alert, $629) runs a toaster, coffee maker, and refrigerator together.
More kitchen wattage: coffee maker, air fryer, microwave, and electric stove.
