Simple 12V/24V booster charger for E-Scooter, E-Bikes or for something else.
Charger MAX INPUT voltage is 30V as monitor power supply range is 4-30V.

I use charger to charge my e-scooter from 12V Solar system and in the car.
Remember to first check/calibrate charger display, use mutlimeter to measure the booster output and adjust charger meter to show same voltage, current might need also calibration.
Adjust output Voltage before you connect the charger plug to Scooter/Bike.
My scooter have 36V battery and max charge voltage is 42V so i set output to 42V.
Booster output power:
12V 5A = 60W / 42V = 1.4A, i tweak my charger for 1.2A max.
24V 5A = 120W / 42V = 2.8A, i would use max 2.5-2.4A ish.
Of course you build this charger at your own risk, i am not responsible for any damage.
