If that happens, the charger can face extreme damage along with the battery. It can also burn the entire battery.


Even if the battery survives overcharging somehow, it faces the danger of getting extremely heated due to the high-intensity charge from the car charger.

Overheating may cause enough damage that cannot be controlled or repaired. Worst-case scenarios tell that you might have to replace the charger completely, which is costly after all.

Again, repairing or replacing a battery can be costly.


Since technologies are evolving, electric scooter chargers are getting more modern. Not many, but a few companies manufacturing electric scooters have enabled solar panel charging which is quite sustainable in the long run.

The above-discussed methods are quite safe and pretty much tested and checked. Hence, trying them at home should not be a very big problem if you do not have a proper electric scooter charger with you.

If you still are not confident with these processes you might ask a professional mechanic, or buy a charger to take the safer and stable way.
