Knox Gear 12 V DC adapter for portable use

This Knox Gear adapter converts 100 V to 120 V household AC into 12 V DC at up to 150 W peak. The 10.0 inch unit is designed for easy transport and storage. It powers devices such as car cleaners, portable TVs and amplifiers that normally run from a vehicle cigar lighter socket. The package includes a cable with 18 AWG copper conductors for reliable current delivery.

Suits mobile equipment needing 12 V away

Users who need to run 12 V accessories from a wall outlet in a home, office or workshop will find this adapter convenient. The flame-retardant housing and built-in safeguards against overheating, overload, over-charging and short-circuiting add a layer of protection. Buyers who require a different output voltage or a higher continuous power rating should look at other options.

Sustained load stability through smart rectification

An internal synchronous rectifier smart chip and EMI filter convert fluctuating input into a steady 12 V output while suppressing electromagnetic interference. The 0.75 mm² copper cable with individual insulation and a flexible PVC jacket maintains conductivity during extended sessions. Continuous operation at the 120 W rated level is supported by the thermal and overload protection circuits.

Questions about this item

What input voltage range does the Knox Gear adapter accept from a wall outlet?

The adapter accepts 100V to 120V AC household current and converts it to 12V DC for your devices.

Can I use the 18AWG cable on equipment that draws the full 150W peak rating?

The 3×0.75 mm² copper conductors are sized for the adapter's 120W continuous and 150W maximum output limits.

How do I confirm the unit is delivering stable 12V DC after I plug it in?

The built-in synchronous rectifier chip and EMI filter maintain steady voltage; measure the output with a multimeter to verify 12V DC under load.
