| Specification | Details |
|---|---|
| Compatible Platform | Unitree Go2 — xBoom’s listing specifies the Go2; confirm separately with xBoom if you need this for a Go2-W unit |
| Compatible Batteries | Both the Go2 Standard Battery (BT2-05) and the Go2 Long Life Battery (BT2-06) |
| Vs. Standard Charger | Roughly 2.5× the output power (302W vs. 119W) cuts both batteries’ charge times to well under half — 48 minutes vs. 2 hours for the Standard battery, 1.5 hours vs. 4 hours for the Long Life battery |
| Typical Use Case | Primary charger for teams prioritizing minimum downtime, or a fast-charging spare for fleet operations |
More Power, Smaller Footprint
Unitree Go2 Fast Charger: Built to Minimize Downtime
The Unitree Go2 Fast Charger swaps the Standard Charger’s 119W output for a substantially higher 302.4W (33.6V at 9A), cutting the Go2 Standard Battery’s charge time from around 2 hours down to roughly 48 minutes, and the Long Life Battery’s from 4 hours down to about 1.5 hours. It still accepts 100-240V AC, so it works anywhere in the world without a separate converter.
Despite the higher output, the Fast Charger’s own housing is actually smaller than the Standard Charger’s — 154×60×36mm versus 210×108×48.2mm. If minimizing downtime between charging sessions matters more than anything else, this is the charger built for that.
302.4W Output
Roughly 2.5x the Standard Charger’s power, for meaningfully faster turnaround.
~48min Standard Charge
The Standard Battery goes from empty to full in well under an hour.
~1.5h Long Life Charge
Even the higher-capacity battery charges in a fraction of the usual time.
Smaller Than the Standard Charger
More output power in a more compact, more portable housing.
Built for Teams That Can’t Afford Downtime
The Unitree Go2 Fast Charger is engineered to get a battery back in service as quickly as safely possible.
⚡
302.4W High-Speed Output
Roughly 2.5x the Standard Charger’s power for a meaningfully faster turnaround.
🔋
Charges Both Battery Types
Works with the Standard and Long Life battery alike, no second charger needed.
⏱️
~48min / ~1.5h Charge Times
Both batteries return to full charge in a fraction of the usual wait.
🔌
Universal 100-240V Input
Works on power grids across almost every country, no converter required.
📏
Compact 154×60×36mm Build
Smaller than the Standard Charger, despite delivering more power.
