Unitree B1 Contact Charger Assembly: A Complete, Genuine Charging Kit

This is a genuine Unitree charging assembly built specifically for the B1, supplied as a complete kit: the contact charging pad, a matching 58.8V charging adapter, and the robot abdomen charging electrode kit needed to complete the installation. That 58.8V figure isn’t arbitrary — it matches the B1’s own official 58.8V nominal battery voltage exactly, so this charger is properly matched to the robot’s actual power system rather than a generic universal unit. The low-profile 507 x 290 x 19.5mm pad is designed to sit flush in an industrial facility or lab rather than taking up awkward floor space.

As with Unitree’s other contact-charging kits, it’s worth being clear about what’s in the box: this is a hardware-only kit. It gives the B1 a reliable way to physically connect and charge through direct contact, but automatic docking and autonomous charging behavior — the robot finding and aligning itself to the pad on its own — is not included here and would need separate navigation software. That makes this assembly best suited to OEM replacement of worn charging hardware, or as the physical foundation for a custom charging station you’re building the docking logic for yourself.
