If you own an electric scooter you will also need an electric scooter charger. Plus, you should also have a spare electric scooter charger in case your old one is lost or stops working. And if you should ever lose track of that electric scooter charger, what can you do? The obvious choice is to buy a new one, but would you know which type of electric scooter charger is the right one for your scooter? Would you know which replacement battery charger would be compatible with your electric scooter?
Obviously, the easiest way to solve this problem would be to buy your scooter manufacturer’s recommendation. Unfortunately, this is not always an easy thing to determine if you have lost your electric scooter charger manual or bought your scooter used and never got a manual. If you ever find yourself in this predicament you may have to do a little homework to figure out which type of electric scooter charger you should purchase.
When choosing a battery charger there are three main factors that must be considered if you expect to buy one that’s compatible with your scooter. These three elements are the connector type, output voltage, and output amperage.
The connector can be one of several types depending on the manufacturer. The most common type of battery chargers use 2-port and 3-port inline connectors. They are typically found on most Chinese scooters including Razor, Rad-2-Go, Boreem, E-Scooter, Scoot-N-Go, Scoobug, X-Treme, Viper, and many others.
3-Pin XLR connectors are often seen on 12 volt, 24 volt, and 36 volt electric scooters. Some manufacturers using these connectors are Schwinn, Mongoose, Tiger, Bladez, E-Boarder, Currie, GT, and many others.
Coaxial connectors are usually seen on a smaller child’s electric scooter with 12 and 24 volts. 2-Prong connectors are found on scooters manufactured by Classic, E-Boarder, Zap, and others. They are typically seen on 12 volt models. 3-Port House connectors are usually found on 24 volt and 36 volt electric scooters.
The output voltage is the next factor and must match the voltage of the scooter. The voltage on the motor, controller, and battery will all match identically. Almost all electric scooters are either 24 volts or 36 volts. If you are unsure you can find out by counting your batteries and adding the voltages together. For example, if you have two 12-volt batteries you have a total of 24 volts. If you have three 12-volt batteries you have a total of 36 volts. You can also take the easy way out and simply read the label on your controller or motor.
The final factor concerns the output amperage of the electric scooter charger, or the current. The battery output should be matched with the size of the battery. If you try using an electric scooter charger with a small output of power it can take a long time to charge a large battery. On the other hand, if you use an electric scooter charger with a high output of power for a small battery, the battery can overheat, causing damage and risking explosion.
The following table contains approximate output amperage (current) for an electric scooter charger:
| Battery Size (Ah) | Output Amperage (Current) |
| 3.5 – 6 7 9-10 12 18 31-35 (U1) 50 – 55 (22NF) 75 110 |
0.4 – 1.0 1.0 – 2.0 1.5 – 2.0 1.5 – 4.0 1.5 – 5.0 3.0 – 8.0 5.0 – 8.0 8.0 8.0 |
