A 1,000W pure sine wave inverter covers the loads most van builders have day-to-day, with one notable exception: anything that cooks or heats on 120V. Here's what fits and what doesn't.
What a 1,000W inverter runs easily
| Appliance | Watts | Notes |
|---|---|---|
| Laptop | 45–90W | No issue |
| Phone charging | 5–25W | Negligible |
| Tablet | 10–30W | No issue |
| LED TV (24–32") | 30–80W | Fine |
| CPAP (no heated humidifier) | 30–60W | Fine; pure sine required |
| Electric blanket | 100–200W | Fine |
| Small fan | 20–50W | No issue |
| LED desk lamp | 5–15W | No issue |
| Bluetooth speaker (via USB or AC adapter) | 5–20W | Fine |
| Camera battery charger | 20–60W | Fine |
| Small blender (NutriBullet-style) | 600–900W | Works at the limit |
| Toaster (small/short cycle) | 800W | Works at the limit |
What's at or over the limit
| Appliance | Watts | Reality |
|---|---|---|
| Drip coffee maker | 600–1,200W | Works at 600W; 1,200W is too close to the limit |
| Keurig/Nespresso | 1,200–1,500W | Exceeds a 1,000W continuous rating |
| Induction cooktop | 1,200–1,800W | Exceeds — need 2,000W inverter |
| Microwave | 900–1,600W (wall draw) | Likely exceeds depending on model |
| Hair dryer (high) | 1,500–1,800W | Exceeds |
| Electric kettle | 1,000–1,500W | At or over the limit |
When 1,000W is enough
A 1,000W inverter is the right size if your van life doesn't involve 120V cooking. Many van lifers use a propane or butane stove for cooking and rely on 120V only for laptop, phone, CPAP, and entertainment. For this use case, 1,000W is plenty and costs less.
When to upgrade to 2,000W
Choose a 2,000W inverter if you:
- Cook on an induction cooktop
- Make coffee from a drip maker or pod machine
- Use a hair dryer or electric kettle
- Want flexibility to run appliances you don't own yet
The price difference between a 1,000W and 2,000W Renogy pure sine inverter is about $80 — usually worth the upgrade for the flexibility.
Recommendations
- Renogy 1000W Pure Sine (~$120) — solid for light loads
- Renogy 2000W Pure Sine (~$200) — the upgrade that covers almost everything
