The 54.6V 2A Xiaomi charger is designed for Xiaomi electric scooters that use 48V batteries. The charger’s output voltage is 54.6 V, and its charging current is 2 A. It is compatible with the Xiaomi Mi 4 Pro Max, Mi 4 Pro Plus, and the newer Xiaomi Mi 5 Max model.

This is a good choice when replacing a broken charger or when you want to have an extra charger at home, at work, or in another frequently visited location. The 2 A charging current is designed for charging the batteries of these scooters, and the appropriate 54.6 V final voltage allows for a full charge of a 48 V nominal voltage battery.

Specifications for the 54.6V 2A Xiaomi Charger

The charger plugs directly into the scooter’s charging port. The power supply supports a wide input voltage range of 100–240 V AC, making it suitable for the standard 230 V electrical grid in Lithuania and other European countries.

Basic parameters:

• nominal battery voltage: 48 V;
• charger output voltage: 54.6 V DC;
• charging current: 2 A;
• Input voltage: 100–240 V AC;
• frequency: 50/60 Hz;
• weight: about 0.363 kg;
• overload protection;
• overheating protection;
• short-circuit protection.

Compatibility of the Xiaomi Electric Scooter Charger

The 54.6V 2A Xiaomi charger is compatible with the following models:

• Xiaomi Mi 4 Pro Max
• Xiaomi Mi 4 Pro Plus
• Xiaomi Mi 5 Max
• Ninebot Segway ZT3 Pro

It is important to pay attention not only to the charger’s voltage but also to the connector. Different models of Xiaomi electric scooters may use different charging connectors, so you shouldn’t choose this charger based solely on the 48 V battery voltage.

Why is a 54.6V charger used for a 48V battery?

48 V is the rated voltage of the scooter’s battery, while the voltage of a fully charged battery is higher. Therefore, a charger with an output voltage of 54.6 V is used for these models.

This is important when choosing a replacement charger—the “48 V” label on the scooter or battery does not mean that the charger’s output must also be 48 V.

Using the 54.6V Scooter Charger

Before charging, it is recommended that you check that the charger connector and its contacts are not damaged. During charging, the power supply unit must be kept in a dry, well-ventilated area and should not be covered.

If the charger is intended to replace an old one, it’s a good idea to compare the old charger’s output voltage, current, and connector type before purchasing.
