About the Unitree G1 Charger
The Unitree G1 battery charger is the official charging adapter for the G1 humanoid's quick-release 9000mAh (421.2Wh) battery: a 54V ⎓ 5A smart charger, sold under Unitree part number G1-BCHARGER, that brings a flat G1 battery back to full in about 1.5 hours. It is the same charger every G1 and G1 EDU ships with, and there is only one G1 charger version — no standard or fast split to cross-check.
The charger runs on any mains supply from 100 to 240V at 50/60Hz, so it travels between labs, demo venues and deployment sites without a voltage converter. The battery charges outside the robot — slide the quick-release pack out of the G1, connect it to the charger, and the battery's own BMS manages the charge curve end to end.
At roughly 1.5 hours per full charge, one charger keeps a two-battery rotation moving indefinitely: one pack works in the robot while the other charges, and the swap is a bench-side job that takes seconds.
Full G1 Battery Charge in About 1.5 Hours
The Unitree G1 battery charger delivers 54V at 5A, bringing the robot's 9000mAh (421.2Wh) quick-release pack from flat to full in about 1.5 hours. The battery's self-developed BMS manages the charge curve — balanced charging with overcharge, over-discharge and short-circuit protection — so the pack is looked after automatically while it charges on the bench.
In practice that speed defines the G1's daily rhythm: with a second G1 battery on the charger, one pack works in the robot while the other refills, and the tool-free quick-release design turns the swap into a seconds-long bench-side job.
Built for the G1 and G1 EDU Battery Bay
Every G1 variant — the standard G1 and the G1 EDU — shares the same battery bay, connector and 9000mAh pack, so this one charger covers the whole G1 line. There is no version split to worry about: the G1-BCHARGER is the only charger the G1 uses.
It is not a cross-model Unitree charger, though. Go2, H1 and other Unitree robots run different batteries at different voltages with different connectors, so their chargers are not interchangeable with this one. Running a mixed fleet? Tell us which robots you have and we will confirm the right charger for each.
