UK kettles draw 2,000-3,000W. Running one from a battery requires careful planning.
Kettle Power Draw
- Standard UK kettle: 2,200-3,000W
- Low-wattage kettle (e.g., Breville HotCup): 800W
- Travel kettle (12v): 120-180W (takes 10-15 min to boil)
Inverter Size
A standard kettle needs a minimum 2,500W (continuous) inverter. Recommend: 3,000W to be safe. Pure sine wave (some kettles hum on modified sine wave).
Battery Impact
A 3,000W kettle draws 250A from a 12v battery. Running it for 3 minutes consumes 12.5Ah. A 100Ah battery can boil a kettle about 6-7 times before reaching 50% discharge.
Reality Check
Running a standard kettle from an inverter is hard on batteries. Most van lifers use:
- A gas hob kettle (no electric, £10)
- A 12v travel kettle (£20-30, slow but works)
- A Jetboil (gas, fast, £60)
Recommended Inverters
| Inverter | Power | Type | Price |
|---|---|---|---|
| Victron Phoenix 1200VA | 1,200W | Pure sine | £200 |
| Renogy 2000W | 2,000W | Pure sine | £180 |
| NDS 3000W | 3,000W | Pure sine | £150 |
Verdict
For occasional kettle use, a 1,200W inverter with a low-wattage kettle works. For everyday use, use gas.
