WAWEIS

WAWEIS 120V 12V 4A 48W 12VDC AC/DC Adapter Cigarette Lighter Plug Socket 10Ft Cord

SKU CH-3R35-353QZ

Converts 100-240 VAC to 12 VDC at 4 A with a 10 ft cord and cigarette-lighter socket, plus overload, over-voltage and short-circuit protection

  • World-wide 100-240 VAC input works on any mains supply
  • 10 ft power cord gives flexible placement in RV or home
  • 48 W output with 4 A current runs 12 V devices reliably
  • FCC, CE and RoHS certified for verified safety compliance
  • Over-voltage, over-current, short-circuit and total-power protection built in

What this adapter does

This WAWEIS unit converts 100-240VAC mains power into a regulated 12VDC output at 4A, delivering up to 48W. It terminates in a cigarette-lighter style socket so devices wired for a vehicle 12V port can be run from a wall outlet. A 10ft cord gives placement flexibility for RV, camper or workshop use.

Who it suits and who it does not

It suits anyone powering 12V accessories such as portable fridges, lights or chargers from household or campsite AC. It is not for buyers who need a higher current rating than 4A, a different output voltage, or a hard-wired installation without the socket. Laptop owners looking for a barrel-tip charger should look elsewhere.

Behaviour under sustained load

The adapter includes over-current, over-voltage, short-circuit and total-power protection circuits that trigger before components overheat. A smart chip monitors temperature and shuts the output down if thermal limits are reached, then restarts automatically when conditions normalise. This allows continuous operation at the rated 48W without the voltage sag seen in unprotected units.

Questions about this item

What AC mains socket and voltage range does this 120V 12V 4A 48W adapter require to operate?

The adapter accepts a worldwide input of 100-240VAC at 50/60Hz, so any standard wall outlet within that range will power it.

Can I keep using my existing 12VDC devices that draw up to 4A with this 48W converter?

Yes, the cigarette lighter socket delivers 12VDC at up to 4A and 48W total, matching the rating of most standard 12V accessories.

How do I confirm the 12VDC output is live after plugging the 10ft cord into the wall?

The socket centre pin will show 12VDC when the adapter is powered; a multimeter or a 12V accessory lighting up verifies correct operation.
