ALITOVE AC to DC Converter 110V to 12V 20.8A 250W(Pro Max) Car Plug to Wall Plug Adapter 120V AC to DC 12 Volt 20A 15A 10A Power Supply Adapter for Car Refrigerator Tire Inflator Vacuum Cleaner

This converter is designed to let you use 12 V car accessories (which normally plug into a vehicle’s cigarette-lighter socket) directly from standard household AC power (100–240 V). Essentially, it transforms AC mains power from your home or workshop into 12 V DC output, up to 20.8 A and 250 W max.

Key Features

【 Specifications 】 Input: 100~240V 50/60Hz; output: 12V DC, 20.8A 250W max; Works well with car devices that draws less than 20.8A, such as 5A, 8A, 10A, 12A, 13A, 15A, 16A, 18A, 20A, 20.8A. Please don’t overload this power adapter over 250W for a long time. Otherwise, the lifespan will be greatly shortened. 11.5ft power cord to reach a wide range.
【 Multiple Safety Protections 】 Built in automatic over voltage protection, over current protection, over temperature protection and short circuit protection. When the load is above 300W, it will stop working and beep. When load is lower than 250W, it will work again. When load is above 660W, the built-in fuse will blow and the power converter will be permanently damaged.
【 Wide Compatibility 】Works with almost all 12V under 250W automotive electronics with cigarette lighter plug, such as air compressor, car tire inflator, coffee maker, car oxygen bar, refrigerator, car TV, car cleaner, car dash cam, car DVR video recorder, car MP3 player, car Bluetooth FM transmitter, car massage cushion, car air fan, etc.
【 Work Quietly, Low-heat Running 】 Built-in a smart silent cooling fan. When the current reaches 8A or higher, the fan will rotate to dissipate heat. This will effectively guarantee continuous working in silence, avoid running overheat and greatly extend its service life.
【 What you will get 】1x 12V 20.8A 250W power supply. 100% quality guarantee, worry-free shopping. 24-month warranty and friendly customer service. We are always stand behind our product. If there is any issue, please contact us, we will reply in 12 hour

Key Considerations

1

Power requirements of your device — ensure your device’s wattage and current draw stay under 250 W / 20.8 A.

2

Duty cycle / continuous vs starting load — some devices (especially with motors like vacuum cleaners, compressors) draw significantly higher current at start-up.

3

Safety protections & build quality — over-voltage, over-current, over-temperature, and short-circuit protections matter for safety and device longevity.

4

Compatibility of device plug — your 12 V device must have a standard cigarette-lighter plug.

5

Intended usage environment — using at home, workshop, or stationary setting vs inside a vehicle; ensure proper ventilation and stable electrical supply.

1

The converter outputs 12 V DC, up to 20.8 A (250 W max). That means devices drawing up to ~20A / 240–250W should work — e.g. small to medium car refrigerators, air compressors, tire inflators, small vacuum cleaners, etc. However, if you exceed 250 W continuously, the lifespan may decline. The manufacturer recommends not overloading it for long durations. The adapter includes built-in protections: over-voltage, over-current, over-temperature, and short-circuit protection.

These factors represent the most critical aspects that will impact your satisfaction with this product.

Frequently Asked Questions

Final Verdict

The ALITOVE AC to DC Converter 110V to 12V 20.8A 250W is a versatile and useful adapter if you want to run car accessories and 12 V devices at home — no need for a car battery or vehicle. It's especially handy for devices like car refrigerators, inflators, vacuum cleaners, compressors, fans, and other moderately powered automotive electronics. Its relatively high wattage limit (250 W), combined with built-in safety protections and cooling, make it a more robust choice than basic cigarette-lighter adapters.
