The unit includes a 10 ft power cord for flexible placement. It is built with new components and carries FCC, CE and RoHS certifications.

29V Output and Protection Headroom

The adapter delivers a fixed 29VDC output suitable for the specified laptop models. Integrated safety circuits provide over current protection, over voltage protection, short circuit protection and total power protection. A smart chip adds overheating protection while high-quality wires and isolation materials support overload and anti-interference performance. The charger is tested to meet OEM specifications for the listed devices.

Barrel Tip Connector Constraints

Connection is made through a barrel round tip that must match the laptop's charging port exactly. The 10 ft cord length sets the maximum reach from the mains outlet to the device. Compatibility is limited to the models identified in the product data, specifically Zb-a290020-a, Zb-a290020-b and 500407. Laptops requiring a different voltage, connector shape or proprietary communication protocol cannot use this adapter.
