What Size Portable Power Station Runs Your Appliance?
Select any household, medical, or camping appliance below to see its typical hourly watt draw, motor startup surge, and estimated runtime hours across Jackery, EcoFlow, Anker SOLIX, and BLUETTI battery backups.
Full-Size Kitchen Refrigerator (Energy Star)
Modern full-size kitchen fridge/freezer combo. Compressor cycles on ~38% of the time (~61W average hourly draw, 160W active compressor draw, 650W startup surge).
Chest Freezer / Deep Freezer (7–15 cu. ft.)
Garage or basement chest freezer. Thick insulation means the compressor only runs ~32% of the time (~38W effective hourly draw).
CPAP / BiPAP Machine (Standard Mode)
ResMed AirSense 10/11 or Philips CPAP running overnight. Uses ~45W with humidifier/heated tubing on, or just 15W–20W with humidifier off on 12V DC.
Basement Sump Pump (1/3 HP Submersible)
Standard 1/3 HP residential sump pump. High 1,800W motor startup surge, but only runs intermittently when the float switch triggers (~15% duty cycle during storms).
Wood Pellet Stove (Auger, Blower & Igniter)
Harman, Quadra-Fire, or ComfortBilt pellet stove. Pulls ~400W–450W for 10 minutes during startup ignition, then settles to ~135W continuous for the convection fan and auger.
Gas / Propane Home Furnace Blower Motor
Central natural gas or propane forced-air furnace. Even though gas creates the heat, the 120V blower fan & igniter need ~550W (cycling ~40% of the time) to heat your house!
Starlink Satellite Dish & Wi-Fi Router
Standard Starlink Gen 2 / Gen 3 terminal & router (snow melt off). Averages 55W–75W continuous draw while working remotely or streaming.
12V Portable Camping Fridge / Cooler (45L)
12V compressor cooler (ICECO, BougeRV, Dometic). Runs directly off the 12V car socket port at ~16W average hourly draw.
Home Fiber/Cable Modem + Wi-Fi 6 Router
Standard ISP gateway or cable modem + mesh Wi-Fi router. Keeps fiber/cable internet live when your neighborhood loses electrical power.
Countertop Microwave Oven (1,000W Cooking)
A '1,000W cooking power' microwave actually pulls ~1,500W from the wall outlet! Used for 15–25 minutes total per day to heat meals.
Drip Coffee Maker / Keurig Single-Serve
Heating element pulls 1,000W–1,450W while brewing for 5–10 minutes each morning (~250Wh–350Wh per pot).
Heated Electric Blanket / Mattress Pad
Queen/Twin heated throw or electric mattress pad on Medium setting. Pulls just ~45W average—using 25x LESS battery than a space heater!
Residential Well Water Pump (1/2 HP 120V Jet Pump)
1/2 HP shallow/convertible 120V jet well pump filling a pressure tank. High 2,200W startup surge, but only runs a few minutes per hour when water is used.
Portable Electric Space Heater (Low Setting 750W)
Ceramic space heater on Low (750W) setting with thermostat cycling. Note: Resistive heating uses massive battery capacity—electric blankets (65W) are 15x more efficient!
Window / Portable Air Conditioner (5,000–8,000 BTU)
Small bedroom window AC or inverter AC unit. Pulls ~550W when cooling and cycles ~60% of the time once the room cools down.
Home Medical Oxygen Concentrator (5L Continuous)
Stationary 5L home oxygen concentrator (e.g., Invacare / Philips Respironics). Continuous 300W–350W medical load.
Countertop Air Fryer / Toaster Oven (1,500W)
Ninja, Cosori, or Breville air fryer / convection toaster oven. High 1,500W draw while cooking, but cooks meals in just 15–20 minutes (~425Wh per meal).
Portable Induction Cooktop Burner (Medium-High)
Single-burner Duxtop or NuWave induction hot plate. 90% energy transfer directly into the pan makes it far more battery-friendly than electric coil burners.
Aquarium / Reef Tank Heater, Canister Filter & Air Pump
50–100 gallon freshwater or saltwater reef tank (150W submersible heater cycling ~40% + 30W continuous filter/wavemaker/air pump).
Residential Garage Door Opener (1/2 to 3/4 HP)
