Compatible Power Supply for Poly Rove 30/40/B2/B4/R8

This original Poly 5V DC adapter delivers a steady 2A output for the Rove 30, 40, B2, B4 and R8 handsets. It replaces a lost or damaged charger with the exact voltage and current the devices expect. The unit is built to HP specifications for consistent daily charging.

Steady Output Under Continuous Use

The adapter maintains a regulated 5V DC supply at 2A during extended charging sessions. This stable output prevents voltage sag that can slow charging or stress the handset battery over time. It is designed for reliable operation whenever the handset is docked.

Check Connector and Region Before Ordering

Verify that your handset uses the same barrel connector as the original supply. This model is the US version with a North American plug, so it requires a compatible socket or travel adapter for other regions. Confirm the 5V/2A rating matches the label on your device.
