How Many Watts Does a Crockpot Use?
ZacharyWilliamUpdated December 23, 2025 · Practical energy guide for U.S. home cooking
“Crockpot” is often used to mean any slow cooker, and wattage varies by size, model, and heat setting. The good news: slow cookers are usually modest loads, so it’s easy to estimate electricity cost and whether a portable power station can run one during an outage or while camping.

Quick answer: a crockpot typically uses about 45–210 watts
Those ranges come from a Crock-Pot brand support answer about slow cooker power consumption. Your specific unit can be higher (especially larger 6–8 quart cookers), so use the tables below and check your model’s label for the most accurate number.

Typical crockpot watts by size (real model examples)
Below are common wattage numbers you’ll see in specs. Treat these as reference points, then verify your exact model.
| Capacity / type | Typical watt range | Example wattage shown in listings | Source | What it means for planning |
|---|---|---|---|---|
| 2-quart (small) | ~70–120W | 100W power rating (example unit) | Crock-Pot / Home Depot | Great for dips/sides; easier to run on smaller batteries. |
| 6-quart (most common family size) | ~180–280W | 240W listed for a 6-qt Cook & Carry model | Home Depot | Plan capacity around the nameplate wattage, but expect cycling once hot. |
| 7-quart (large) | ~150–210W (brand guidance) | Many large models land around ~200W on spec sheets | Crock-Pot support guidance | Often still a manageable load for mid-size power stations. |
| 8-quart (extra large / parties) | ~250–350W | 320W listed for an 8-qt digital slow cooker model | Kohl’s listing | Higher draw can shorten battery runtime significantly. |
Tip: The listed wattage is usually the maximum draw while heating. Once the food and ceramic pot are hot, most slow cookers cycle on and off, so the “average watts” over several hours can be lower than the nameplate.
Why your crockpot wattage changes while cooking

- Warm-up vs. steady state: heating from cold draws more power than maintaining temperature.
- Setting (LOW/HIGH/WARM): higher settings generally cycle more aggressively or target higher heat.
- Food mass & starting temp: a full pot from the fridge takes longer to heat than a half pot at room temp.
- Ambient conditions: cold kitchens, garages, and RVs increase heat loss.
If you want a real-world number for your specific recipe and setting, a plug-in power meter (like a “watt meter”) can show both instant watts and kWh over time.
How to find your crockpot’s exact wattage
-
Check the label: look for a sticker on the bottom or back showing
W(watts) orA(amps). - Search by model number: the model is often printed near the label (for example: “SCCP…”).
- Use the manual: electrical ratings are often listed near safety instructions.
- Measure it: a watt meter is the fastest way to confirm real usage during a cook cycle.

If your label lists amps instead of watts, use: Watts = Volts × Amps. In the U.S., most slow cookers are 120V. Example: 120V × 2A ≈ 240W.
Watts → kWh → cost (with quick tables)

Your electric bill is based on energy (kWh), not watts:
kWh = (Watts ÷ 1000) × HoursCost = kWh × Your electricity rate
| Load (W) | Cook time (h) | Energy (kWh) | Cost @ $0.12/kWh | Cost @ $0.16/kWh | Cost @ $0.24/kWh |
|---|---|---|---|---|---|
| 100 | 4 | 0.40 | $0.05 | $0.06 | $0.10 |
| 100 | 8 | 0.80 | $0.10 | $0.13 | $0.19 |
| 150 | 4 | 0.60 | $0.07 | $0.10 | $0.14 |
| 150 | 8 | 1.20 | $0.14 | $0.19 | $0.29 |
| 200 | 4 | 0.80 | $0.10 | $0.13 | $0.19 |
| 200 | 8 | 1.60 | $0.19 | $0.26 | $0.38 |
| 240 | 4 | 0.96 | $0.12 | $0.15 | $0.23 |
| 240 | 8 | 1.92 | $0.23 | $0.31 | $0.46 |
Real-world costs can be a bit lower than the “Load (W)” math if your cooker cycles (on/off) after it reaches temperature. If you want the true cost for your recipe, measure total kWh with a watt meter.
Can a portable power station run a crockpot?

Usually yes—if you match output and energy capacity.
- AC output (watts): your power station’s continuous AC output should be higher than your crockpot’s draw.
- Battery capacity (watt-hours / Wh): determines how long it can run.
- Inverter efficiency: some battery energy is lost converting DC battery power to AC household power.
Rule of thumb for runtime on AC: Runtime (hours) ≈ (Battery Wh × 0.85) ÷ Load W
(Using 0.85 as a reasonable planning efficiency. Actual results vary with temperature, inverter load, and device cycling.)
UDPOWER sizing guide + crockpot runtime estimates
If you’re planning for outages, RV travel, or off-grid cooking, here are practical pairings using UDPOWER portable power stations. The specs below are from UDPOWER product pages.

| UDPOWER model | Picture | Battery capacity | AC output | Solar input (max) | Est. runtime @ 100W | Est. runtime @ 150W | Est. runtime @ 210W | Est. runtime @ 240W |
|---|---|---|---|---|---|---|---|---|
| C200 | ![]() |
192Wh | 200W rated (400W surge) | Up to ~100–120W | ~1.6h | ~1.1h | Not recommended | Not recommended |
| C400 | ![]() |
256Wh | 400W rated (up to 800W peak in UD-TURBO) | Up to 150W | ~2.2h | ~1.5h | ~1.0h | ~0.9h |
| C600 | ![]() |
596Wh | 600W rated (1200W surge) | 240W max (12–60V, 8A) | ~5.1h | ~3.4h | ~2.4h | ~2.1h |
| S1200 | ![]() |
1190Wh | 1200W rated (1800W max) | 400W max (12–75V, 12A) | ~10.1h | ~6.7h | ~4.8h | ~4.2h |
How to use this table: 1) find your crockpot’s watts (label/spec), 2) pick the nearest column, 3) treat results as a conservative estimate—many slow cookers cycle after heating, which can extend real runtime. For long cooks, pairing a larger station with solar recharging can help maintain power over the day.
Practical pairing suggestions (light-touch)
- Small dip/side dishes (2–3 qt): C200 can work if your cooker stays within ~200W.
- Typical family meals (6 qt, ~240W listed on many models): C600 is a comfortable starting point for a few hours of AC cooking.
- Longer outage planning / larger cookers: S1200 provides more buffer and supports higher solar input for daytime replenishment.
Food safety notes (worth knowing for long cooks)

A slow cooker is great for low-and-slow cooking, but food safety still matters—especially if you’re powering it during an outage and want to avoid temperature dips.
- Hot holding: keep hot food at 140°F or warmer.
- Leftovers: refrigerate within two hours after cooking is finished.
- Reheating: USDA guidance recommends reheating leftovers to 165°F using stove/microwave/oven, then using the slow cooker to keep food hot (not to reheat from cold).

FAQ
Is “crockpot wattage” the same as “slow cooker wattage”?
In everyday searches, yes. “Crock-Pot” is a brand, but people often use “crockpot” to mean any slow cooker. The wattage rules of thumb apply to most slow cookers.
Does a crockpot use more watts on HIGH than LOW?
Typically yes. Crock-Pot brand guidance puts LOW around ~45–150W and HIGH around ~150–210W, depending on the unit. Larger models may exceed those ranges.
Why does my slow cooker wattage “jump around” on a watt meter?
That’s normal. The heating element cycles to maintain temperature—higher draw while heating, then lower/near-zero between cycles.
How much electricity does a crockpot use for 8 hours?
Use kWh = (W ÷ 1000) × hours. Example: at 200W for 8 hours, that’s 1.6 kWh. Your real number can be lower if your unit cycles after warming up.
Is a crockpot cheaper to run than an oven?
Often, yes—slow cookers are typically a few hundred watts, while ovens can be much higher. The exact comparison depends on your oven and cook time.
Can I run a 6-quart crockpot on a small power station?
Maybe for a short time. Many 6-quart models are listed around ~240W. You’ll want a power station whose AC output exceeds that and enough Wh capacity for the hours you need.
Do I need “pure sine wave” AC for a crockpot?
A crockpot is primarily a resistive heating load, so it’s generally tolerant. That said, pure sine wave AC is a good default for household appliances and reduces the chance of compatibility issues.
How do I estimate runtime more realistically?
If you can, measure total kWh used over a full cook with a watt meter. Then you can compare that kWh to your power station’s usable energy.
Can I reheat leftovers in a crockpot?
USDA/FSIS guidance recommends reheating leftovers to 165°F on stove/microwave/oven, then using the slow cooker to keep food hot (rather than reheating from cold in the slow cooker).
What’s the safest way to avoid temperature drops during an outage?
Start with a fully charged power station, avoid running extra loads on the same inverter, and keep the cooker lid closed. If you’re unsure, check food temperature with a thermometer.
What if my crockpot has no watt label?
Use the model number to locate the manual/spec sheet or measure with a watt meter. If it lists amps, convert using Watts = Volts × Amps.
