A freezer’s current depends on the model, supply voltage and operating conditions. Read its rating plate and manufacturer information rather than assuming every medium freezer uses 0.8 to 1.5 amps. Startup demand may differ from running demand.
Where Do You Find the Correct Current?
Use the model’s rating plate or electrical specifications. If the label is missing or difficult to reach safely, ask the manufacturer using the model number instead of moving or dismantling the freezer to guess its rating.
GE advises using the individual freezer’s rating-plate information when planning a generator or other auxiliary supply. The circuit requirement and current draw are separate figures, so check both.
How Are Amps Different from Watts?
Amps measure current, volts describe the supply and watts measure power. For an AC motor, multiplying volts by amps gives apparent power in volt-amperes; real watts can differ because of power factor. Use specified input power or suitable measured energy data when you need actual consumption.
Do not copy the same current figure from a 120-volt freezer to a 240-volt version. For example, 240 volts multiplied by 0.8 to 1.5 amps equals 192 to 360 volt-amperes. This hypothetical range is not a freezer rating.

What Matters for Backup Power?
A compressor can require more current while starting than while running, but there is no universal two- or three-times multiplier or ten-second duration for every freezer. Obtain the model’s starting requirements and check the backup supply’s continuous and surge capability.
Include other loads and the manufacturer’s requirements when selecting an inverter or generator. Have a qualified person assess the setup; a running-watt figure alone is not enough.
How Much Energy Will It Use?
Energy in kilowatt-hours depends on operation over time. The compressor may cycle, and features such as automatic defrost also use energy. Room conditions, door openings, loading and installation affect consumption.
Compare energy labels for the actual models and storage capacity you need. Separate refrigerator and freezer appliances are not automatically more efficient than a combined unit. Keep the required ventilation clearances and use the appliance only within its specified ambient-temperature range.

What About Small or Commercial Freezers?
A small freezer, domestic upright and commercial walk-in system are different products. Do not size their circuits from one general range. Use each system’s electrical documentation, including any separate fans, heaters or other loads.
