Van, RV & Cabin
Off-Grid & Mobile Power
Portable power stations for vans, RVs, cabins, boats and cars.
The short version
Whether you're converting a van, kitting out a cabin with no mains connection, or just want peace of mind on long road trips, portable power stations and leisure batteries have made off-grid living genuinely comfortable. Run a fridge, laptop, lights, and charge everything else, all without a generator.
The right size depends on your daily energy use and how you'll recharge: solar panels for long stays off-grid, or the vehicle's alternator/DC-DC charger for shorter trips.
What to look for
Daily energy budget
Work out watt-hours per day first. Capacity then equals daily use × days between recharges.
Alternator charging
A DC-DC charger refills the battery while you drive — often more reliable than solar in a UK winter.
Enough solar input
Roof or portable panels in the 200–600W range keep most van builds topped up from spring to autumn.
Cold-weather charging
Lithium batteries must not charge below 0°C unless they have built-in heating or low-temp protection.
