Product Overview

Reliable Power, Anywhere You Deploy

The Unitree B2 Battery Charger, Built for Worldwide Use

The Unitree B2 Battery Charger takes the B2’s battery from empty to fully charged using nothing more than a standard AC wall outlet. It accepts 100 to 240 volts AC, so it works on power grids worldwide without a separate voltage converter. It then outputs a regulated 58.8V DC to match the battery’s charging limit exactly.

That regulated output matters. Charging at the correct voltage protects the battery’s long-term health, rather than stressing it with an overshoot or an inconsistent supply. So for teams running a B2 across multiple sites or countries, one charger genuinely does travel anywhere the robot does.

🔌

Worldwide AC Input

100-240V compatibility means one charger works across almost any country’s power grid.

⚡

Matched 58.8V Output

🛡️

Protects Battery Health

Regulated charging avoids the overshoot that shortens a battery’s usable lifespan over time.

🔧

Plug-and-Play Setup

Connect it to the battery and an outlet — there’s no configuration step in between.
