Adjustable Charger for Horwin EK1 and EK3 Electric Scooter 72V-84V 10A

Adjustable Charger Horwin EK1 and Horwin EK3 – 72V (84V) – 3A to 10A with OLED Screen

The adjustable 72V – 3A to 10A charger for Horwin EK1 and Horwin EK3 electric scooters is specially designed for the 72V lithium-ion batteries used on Horwin electric scooters.

Compatible with both 72V 36Ah versions and 72V 72Ah dual battery models, this charger provides stable, secure, and perfectly adapted charging to the electrical architecture of Horwin scooters.

When charging overnight and you are not in a hurry, you can select a gentler charge at 3A or 5A. When you need to quickly regain battery life, you can increase the power up to 10A, allowing for much faster charging than a standard charger.

The ability to adjust the charging intensity also helps to better manage charging temperature and preserve battery life in the long term.

Thanks to its ventilated aluminum casing and active cooling, the charger maintains excellent thermal stability even during fast charges at 10A.

Its integrated OLED screen displays in real time:

• battery voltage
• selected current
• charged capacity

The current setting is easily adjusted via a rotary knob.
