How Many Amps Does a Chest Freezer Use?
Chest Freezer draws about 0.8 amps at 120 volts (100 watts running) and briefly spikes to around 5 amps at startup. At 0.8 A, a chest freezer fits comfortably on a standard 15 A or 20 A household circuit (kitchen countertop receptacles are on 20 A small-appliance circuits per NEC 210.11(C)).
Amps = watts ÷ volts. Enter the wattage from your appliance's nameplate or label for an exact figure.

Breaker figure is guidance for a simple resistive load, sized at 125% for continuous running — confirm against the nameplate and a licensed electrician.
Chest Freezer amperage at 120 V and 240 V
Same 100 W load — the current halves when the voltage doubles. Chest Freezer is typically a 120 V appliance in US homes.
| Draw | Watts | Amps at 120 V | Amps at 240 V |
|---|---|---|---|
| Running | 100 W | 0.8 A | 0.4 A |
| Starting (surge) | 600 W | 5 A | 2.5 A |
The startup surge lasts a fraction of a second — it matters for generator sizing and breaker trip curves, not for your electric bill.
Breaker and circuit for a chest freezer
At 0.8 A, a chest freezer fits comfortably on a standard 15 A or 20 A household circuit (kitchen countertop receptacles are on 20 A small-appliance circuits per NEC 210.11(C)). For a dedicated circuit, guidance is a 15 A breaker with 14 AWG copper (75°C terminations) — sized at 125% of the running current because it runs 3+ hours at a time (NEC 210.20).
Guidance only — actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.
