Vszerda E561 Excavator USB Cable

This USB cable is built as a reverse-charging adapter for the E561 excavator electric toy car. It accepts a 7.4 V supply or two 3.7 V lithium-ion cells in an SM4P arrangement. The cable connects the power source to the vehicle's charging port for convenient replenishment.

Sustained load behaviour

The adapter passes current continuously while the battery pack charges, maintaining the 7.4 V or dual 3.7 V input without active cooling. It is not designed for high-current discharge or data transfer, so users needing faster charge rates or communication functions should use the original manufacturer charger.

Questions about this item

How much power does the Vszerda USB cable draw when charging the E561 excavator all day?

The cable delivers 7.4 V from two 3.7 V cells in series, so power draw depends on the excavator's battery capacity and charge state rather than the cable itself.

What battery connector must the E561 excavator already have for this cable to work?

The excavator needs a SM4P connector that matches the cable's 3.7 V x2 lithium-ion pack interface.
