ALITOVE AC-to-DC Converter 110/120V to 12V 30A (360W) Pro Max — 11ft Cord, Safety-Protected Cigarette Lighter Socket

ALITOVE's AC-to-DC converter turns standard 110/120V mains into a stable 12V, 30A (360W max) cigarette-lighter power source for car appliances.

This compact, ventilated power supply lets you run or test 12V automotive devices at home or in the garage without starting a vehicle. With an 11-foot cord and multiple built-in protections, it supplies up to 30 amps continuously for devices such as air pumps, portable refrigerators, vacuums, and small heaters—provided the load stays under 360W. It’s designed for semi-permanent bench or household use and includes audible alerts and a replaceable fuse to guard against extreme overloads.

How does the ALITOVE converter protect my devices and home circuits?

The unit includes automatic safety features that stop operation before dangerous conditions develop. Over-voltage, over-current, over-temperature, and short-circuit protections monitor outputs and either shut down or sound an alarm if thresholds are exceeded. A built-in fuse provides a last-resort failure point to prevent catastrophic damage when voltage or current spikes are extreme.

• Automatic cut-off for loads above 400W and audible beep alerts
• Normal restart when the load falls below the safe threshold
• Fuse protection for extreme overloads (above ~660W)
• Over-temperature and short-circuit detection to save connected devices

What kinds of 12V appliances can I run with this power supply?

Any 12V device that draws under 30A (360W) can be powered, using its standard cigarette-lighter plug. Typical uses include inflators, small refrigerators, dash electronics, and portable fans. Avoid continuously running loads that hover at or above the rated maximum to preserve lifespan.

• Air compressors and tire inflators up to rated current
• 12V fridges, beverage warmers, and small heaters within 360W
• Car vacuum cleaners, dash cams, MP3 players, and Bluetooth transmitters
• Automotive accessories for bench testing or home convenience

How quiet and reliable is the cooling system during continuous use?

ALITOVE built a smart silent cooling fan that only spins when needed to keep noise and wear low. The fan engages when current exceeds about 8A to dissipate heat and maintain stable output during extended operation. This helps prevent thermal shutdowns and extends the unit’s working life under moderate to heavy loads.

• Thermostatically controlled fan activation at ~8A
• Low-noise fan design for indoor or garage use
• Reduced heat buildup for longer continuous runtimes
• Designed to balance cooling needs with quiet operation

What should I know about installation, cable length, and compatibility?

The converter plugs into a standard 110–120V AC outlet and outputs via a cigarette-lighter socket on an 11-foot cord for flexible placement. The long cable lets you position the power supply away from the work area, reducing clutter and allowing easier access to the powered device. Check your appliance’s current draw to confirm it stays below 30A and avoid sustained operation near the maximum rating.

• Input: 110V 50/60Hz; Output: 12V DC, 30A (360W max)
• 11ft power cord for bench or garage reach
• Works with most cigarette-plug 12V automotive electronics
• Avoid sustained loads above 360W to protect lifespan

Who is this for? The ALITOVE 110V to 12V 30A converter is aimed at DIYers, mechanics, hobbyists, and homeowners who need a reliable bench power source for automotive accessories. It’s a practical solution for anyone testing 12V devices without a vehicle, running portable car appliances in the home, or needing a stable 12V supply for light workshop tasks—so long as the device’s current draw stays within the unit’s safe operating range.
