How To Charge Car Vacuum Cleaner At Home

To power a car vacuum cleaner at home—especially the model with a 12V cigarette lighter plug—you have to use one of those “heavy-duty” AC to DC power converters (110V to 12V).

Here is a hard indicator: be sure to look at the ampere. The ordinary low-ampere adapter on the market does not move at all. Most car vacuum cleaners require a high current at the moment of startup, usually between 8 and 10 amps (about 100W to 120W).

Therefore, in order to run the vacuum cleaner smoothly indoors, the power adapter you buy must be rated at least 10 amps, or 120 watts of power.

First Understand The Voltage Difference: 110V AC vs 12V DC

To solve the problem of “how to charge the car vacuum cleaner at home”, the first is to understand the difference in power supply.

The socket on your wall provides 110V alternating current, and your car vacuum cleaner is designed to be used by the 12V direct current system in the car. Because the plug is that special cigarette lighter shape, you can’t physically put it directly into the wall socket.

At this time, the AC to DC converter mentioned just now comes in handy. It is like a “bridge”, responsible for the household high-voltage pressure into your vacuum cleaner motor can eat low-voltage electricity. However, not all converters can do this job.

The Key Role Of Amperes Of Current

Many people buy the cheapest converter directly by price in order to save trouble or money. These small, lightweight adapters are typically only 500mA or 2 amps (about 24 watts).

To tell the truth, these things are prepared for the driving recorder or the small air pump that inflates the tires, and they cannot serve high-power motors at all. The motor of the car vacuum cleaner is very fierce, and it requires a huge starting current.

Starting Surge:

The moment you press the switch, the instantaneous power required by the motor to overcome the static inertia is enormous. This inrush current usually spikes to 8 to 10 amperes.

Consequences Of Low Amperes:

If you just use a 2 amp converter, the electrical adapter required by the vacuum cleaner cannot be supplied, and the safety circuit inside the adapter will trip and power off. After a second it resets, tries to power again, and then trips again. This is why you will hear the vacuum cleaner make that “pulse” start and stop, or simply strike.

Select The Right Equipment

If you want to use the car vacuum cleaner safely at home, this money cannot be saved and you must buy a heavy-duty converter. When purchasing, regardless of whether it looks big or not, look directly at the technical parameter label on the back.

Make a list of “perfect adapters” for you and buy them:

• Input: 100V-240V AC (standard wall plug).
• Output voltage: 12V DC (cigarette lighter socket).
• Output current: at least 10 amps (if you can buy 15 amps more stable, more sufficient margin).
• Output power: at least 120 watts.

Ensuring that the converter has a current rating of at least 10 amps is equivalent to leaving enough “breathing room” for the start-up surge of the vacuum cleaner. Not only does the vacuum cleaner run smoothly, it won’t overheat the adapter or burn out your motor.

How To Do It Correctly

When you have the big guy in your hand—the correct heavy-duty AC to DC converter (110V to 12V, 10A), follow these steps to keep you safe:

1. Check the switch: Before powering on, make sure that your car vacuum cleaner switch is off.
2. Plug in the converter: Plug the plug of that heavy-duty converter (whether it is two-pin or three-pin) into the wall socket in your home.
3. Look at the indicator light: This high-quality 10A converter usually has an LED light on the power “brick.” Make sure it is always bright green or blue, which means the electricity has been turned on.
4. Connect the vacuum cleaner: insert the cigarette lighter plug of the vacuum cleaner into the female seat of the converter, and be sure to insert it tightly.
5. Power on: open the vacuum cleaner switch. Because you are now using a power supply of more than 10 amps, you will find that it roars immediately, without any Caton.
