Method 1: Use a Portable Car Jumper

To charge a razor scooter without a charger, a portable car jumper is a lifesaver. The device can jump-start a car battery when it is dead. It can also be used to charge other devices that use 12V or 24V batteries, such as a razor scooter. To use this method, you will need:

  • A portable car jumper with a 12V or 24V output
  • A pair of alligator clips
  • A multimeter

Steps to follow:

1. Check the voltage of your razor scooter battery using the multimeter. It should be between 12V and 24V, depending on the model.

2. Connect the positive terminal of the car jumper to the positive terminal of the scooter battery using an alligator clip. Do the same for the negative terminals.

3. Turn on the car jumper and set the output voltage to match the scooter battery voltage.

4. Monitor the charging process using the multimeter. The scooter battery should reach full charge when it reaches about 13.5V for a 12V battery or 27V for a 24V battery.

5. Disconnect the car jumper and the alligator clips when the scooter battery is fully charged.

Method 2: Use a Variable Power Supply

A variable power supply is a device that can provide different voltages and currents to power various electronic devices. It can also be used to charge a razor scooter without a charger. To use this method, you will need:

  • A pair of alligator clips
  • A variable power supply with a 12V or 24V output
  • A multimeter

Steps to follow:

1. Connect the positive terminal of the power supply to the positive terminal of the scooter battery using an alligator clip. Do the same for the negative terminals.

2. Turn on the power supply and set the output voltage to match the scooter battery voltage.

A USB cable is a common accessory that can transfer data and power between devices. If you do not have a charger, you can also use it to charge a razor scooter. To use this method, you will need the following:

  • A USB cable with a type A connector on one end and a type B connector on the other end
  • A USB power adapter or a computer with a USB port
  • A razor scooter battery connector

Steps to follow:

1. Cut off the type B connector of the USB cable and strip the wires. You should see four wires: red, black, green, and white. 

The red wire is the positive, and the black wire is the negative. The green and white wires are for data and can be ignored.

2. Connect the red wire of the USB cable to the positive terminal of the scooter battery connector using electrical tape or solder. Do the same for the black wire and the negative terminal.

3. Plug the type A connector of the USB cable into the USB power adapter or the computer USB port.
