Run Car Accessories at Home – thanks to 110–240V AC to 12V DC conversion
Conversion takes household mains between 110 and 240 volts and steps it down to a stable 12V DC output at up to 10 amps, with a maximum usable load of 120W. The car-socket output accepts any standard cigarette-lighter plug.
Power cool boxes, portable TVs and tyre inflators from a wall socket without improvising ad-hoc cabling. Portable leisure and garage tasks become straightforward and plug-and-play.
Broad Compatibility – with standard cigarette lighter plugs
Output matches the voltage and plug form used by vehicle chargers, allowing direct connection of devices that normally plug into a car’s 12V socket. No specialised adapters are required for standard car-plugged equipment.
Phone chargers, coolers, inflators and other 12V accessories can be used at home as long as the device draws 120W or less. Saves having to extract batteries or run a vehicle to operate kit.
Quiet, Reliable Operation – with conservative power rating and simple design
A modest 10A rating and 120W cap reduce continuous stress on internal components, which lowers heat generation during typical use. User feedback highlights steady delivery without excessive noise or overheating during normal operation.
Suitable for longer sessions such as keeping a cool box running while socialising or inflating tyres in the garage without distracting fan noise or worrying about quick shutdowns.
