BASEUS

BASEUS C20 AC to DC Converter 20A 240W 11.61FT 110V-240V to 12V ac adapter

SKU CH-XMQB-NRN8A

Converts 100-240 V AC mains to 12 V DC at up to 20 A and 240 W with an 11.61 ft lead for car accessories

  • TypeAC Adapters
  • Powers 12 V car devices from 110 V–240 V mains
  • 61 ft cable gives flexible placement indoors or out
  • 240 W / 20 A output runs inflators, fridges, vacuums
  • CE FCC RoHS certified with six protection circuits
  • Fan-less design keeps operation quiet and efficient

Power input range

This BASEUS C20 converter changes household AC power at 100 to 240 volts and 60 hertz into a steady 12 volt DC supply. It is built for owners of car-powered gear who want to run that equipment from a wall socket.

Continuous load behaviour

The unit delivers up to 20 amps and 240 watts without time limits, so an inflator, refrigerator or vacuum can run for extended periods. Internal circuitry guards against over-current, over-voltage, short circuits and over-temperature, while the high-efficiency layout keeps heat and fan noise low during long sessions.

Upgrade path and limits

It replaces shorter or lower-rated adapters that cannot sustain 240 watts or that lack the 11.61 foot reach for convenient placement. The converter is not designed to charge batteries, and any device drawing more than the rated power will cause shutdown or damage.

Questions about this item

How much heat and noise does the C20 converter produce when running continuously at high load?

The unit uses a high-efficiency circuit and advanced heat-dissipation design to reduce energy loss and noise; the supplier notes it is normal for the converter to warm up during extended or high-power use and advises stopping immediately if any deformation or melting occurs.

What must I already have to use this converter with my car accessories?

You need a standard household AC outlet supplying 100–240 V at 60 Hz and a device fitted with a 12 V cigarette-lighter plug that draws no more than 240 W or 20 A.

Will the C20 work reliably with older 12 V car appliances I already own?

Yes, it supports most universal 12 V car-powered devices such as inflators, refrigerators, vacuum cleaners, air purifiers and fans as long as each device stays under the 240 W / 20 A limit.
