Most people use their car's 12V socket for one thing: charging a phone. But with a small pure sine wave inverter plugged in, your car becomes a rolling power bank capable of running a surprising amount of everyday equipment. Here are twelve genuinely useful ideas — all within reach of a compact 200W inverter.
- Your laptop — work from anywhere; most laptops need just 45–90W.
- Camera and drone batteries — recharge on the move between shots.
- A Wi-Fi router or dongle — a mobile office or a movie night parked up.
- A small desk or clip fan — relief on a hot day.
- LED lights — for camping, roadside repairs or a late arrival.
- A phone-charging hub — charge several phones at once on a family trip.
- A power bank — top up your big battery pack so it is ready when you are.
- A handheld game console — keeps kids happy on long drives.
- A portable speaker — for a beach or campsite.
- Electric shaver or grooming trimmer — handy before a meeting or event.
- A small breast-pump or baby monitor charger — for parents on the road.
- Tablet and e-reader charging — entertainment for the whole car.
The one rule to remember
Add up the wattage of what you plug in and keep the total comfortably under the inverter's rating. A 200W inverter is perfect for electronics — but it will not run high-power appliances like a fridge or kettle, which need far more (see can you run a fridge on a car inverter).
Why pure sine wave
Sensitive electronics — laptops, cameras, medical devices — want clean power. A pure sine wave inverter delivers exactly that, just like a wall socket, while cheaper modified sine wave units can cause buzzing and heat.
