Campervan Induction Hob Inverter Battery Uk

Direct answer: A portable induction hob is not a 12 V appliance. For off-grid campervan use you need a pure sine inverter rated above the hob’s maximum draw with headroom, plus leisure-battery capacity that matches how long you cook. On campsite or driveway shore power, a plug-in portable can behave much like a flat kitchen appliance — the electrical planning problem is mainly an off-grid problem.

Shore power versus off-grid

On a hook-up, many converters simply plug a portable hob into the van’s AC outlet once the site supply and onboard protection are adequate. Off-grid, the inverter and battery bank become the bottleneck. UK-focused conversion writing notes there is no true 12 V induction hob: you invert to mains AC first — see Nohma’s campervan induction electrics overview.

Inverter and battery sizing (planning level)

Practical guides stress a pure sine inverter that exceeds the hob’s rated maximum; modified sine units are unreliable with induction electronics. Dual portable setups around the common ~2800 W class are often discussed alongside roughly 3000 W inverter headroom and substantial lithium capacity for off-grid days — patterns described by Roam Wired’s induction inverter notes and The Van Conversion’s dual-ring example.

Those figures are planning benchmarks, not a promise for your exact bank. Runtime still depends on battery usable capacity, state of charge, other DC loads, and how hard you run each zone.

Meal schedule that avoids inverter trips

• Boil water first on one zone, then drop power before starting a second pan.
• Favour one rolling boil plus one low simmer instead of two high sears.
• Batch-cook denser meals at lunch on shore power when possible.
• Keep kettle and hob from competing on the same inverter surge window.

Who should wait

Pause if you only have a small AGM bank, a modified-sine inverter, or no clear understanding of continuous versus surge ratings. Fix the electrical foundation with a qualified vehicle electrician before shopping for a double portable hob as your primary cooker.

When a portable double makes sense

If shore-hookup cooking is your main pattern, or your lithium-plus-inverter package already clears a dual portable draw with headroom, a compact double zone can replace gas for many UK trips. Review the current VBGK double induction hob only after the electrical basics are settled. For household socket rules outside the van, see plug-in induction on a UK 13A socket.
