Running an Induction Cooktop in a Van: What Inverter and Battery Do You Need?
Induction cooking in a van is absolutely doable — and once you've used an induction cooktop, going back to propane feels like a step backward. But induction pulls serious wattage, and getting the electrical system right is non-negotiable.

The wattage reality
Single-burner induction cooktops (Duxtop, NuWave, IKEA TILLREDA) typically offer settings from 200W to 1,800W. Boiling water or searing? You're at 1,200–1,800W. Simmering? Maybe 400–600W.
Real cooking scenarios:
| Task | Wattage | Time | Wh used |
|---|---|---|---|
| Boil 4 cups water | 1,500W | 8 min | 200Wh |
| Cook pasta (boil + simmer) | 1,500W → 600W | 20 min | 350Wh |
| Fry eggs | 800W | 5 min | 67Wh |
| Full dinner (stir fry + rice) | 1,500W | 25 min | 625Wh |
An average meal takes roughly 300–600Wh if you're not going crazy on the burner. Cooking twice a day sits around 700–1,200Wh/day from the inverter.
Minimum inverter size
1,500W minimum, 2,000W recommended.
Most induction cooktops draw up to 1,800W at the highest setting. A 1,500W inverter handles this if you keep the cooktop at 80% power — common and practical. A 2,000W inverter lets you run full power without stress.
Pure sine wave only. Induction cooktops have sensitive internal electronics and control boards that require clean AC power. Modified sine wave inverters can cause them to malfunction, trip their protection circuits, or fail prematurely.
Good picks for induction cooking:
- Renogy 2000W Pure Sine Inverter (~$200) — solid, affordable, widely used in van builds
- Victron Phoenix 12/2000 (~$500) — premium quality, Victron ecosystem integration
- Victron MultiPlus 12/2000 (~$650) — if you also want built-in shore charging
Minimum battery size
Induction cooking is the most demanding load most van builders add. Here's how different battery sizes hold up:
| Battery bank | Usable Wh | After cooking dinner (600Wh) | Reality check |
|---|---|---|---|
| 100Ah LiFePO4 | ~1,024Wh | ~424Wh left | Marginal — very little left for fridge, lights, overnight |
| 200Ah LiFePO4 | ~2,048Wh | ~1,448Wh left | Comfortable — enough for evening and overnight loads |
| 300Ah LiFePO4 | ~3,072Wh | ~2,472Wh left | Very comfortable — cook freely without anxiety |
The honest minimum for daily induction cooking: 200Ah LiFePO4 with good solar.

Solar and charging requirements
If you cook on induction daily, your solar needs to account for that load. Add 700–1,200Wh/day for cooking to your other loads, and you'll need 400W+ of solar in most US locations to keep up.
The golden rule for induction cooking in a van: cook at peak solar time (10am–3pm) when your battery is full from overnight and morning charging. You draw down for cooking and immediately start refilling with midday sun. Avoid cooking from a depleted battery at night.

Best induction cooktops for van use
Duxtop 9600LS (~$80) — the most popular choice in the van community. 1,800W max, 20 power settings, compact footprint. Reliable and widely reviewed.
NuWave Flex (~$70) — slightly smaller than the Duxtop, 1,500W max. A good choice if you always cook at 80% power anyway (and you probably will).
IKEA TILLREDA (~$50) — remarkably capable for the price. 1,800W, simple controls, very compact. The secret weapon of budget van builds.
Practical tips
Keep meals under 30 minutes of cooktop time. Longer cooking sessions drain the battery faster than solar can keep up with midday.
Use a lid. Water boils faster, less heat loss, less cooking time, less Wh used.
Use residual heat. Turn off the cooktop 2–3 minutes before food is done — the pan retains enough heat to finish cooking.
Have a backup. A small single-burner propane stove ($30) is worth carrying for days when the battery is low or it's been cloudy for two days. Propane is a practical safety net, not a failure.
Monitor your battery. A battery monitor (Victron SmartShunt) lets you see exactly how much you're drawing while cooking and how much is left. Worth every penny when induction is in the mix.
