45W 19.5V Blue Tip Adapter

This 45W AC adapter delivers 19.5V at 2.31A through a 4.5mm x 3.0mm blue tip connector. It is built for HP Stream 11, 13 and 14 series notebooks that require this specific tip size and polarity. The unit accepts 100-240V input at 50-60Hz for worldwide use.

Connector Verification Required

Installation is straightforward: plug the barrel into the laptop and the IEC cable into a wall socket. The critical step is confirming the 4.5mm x 3.0mm blue tip matches the port on the device, as other HP models use similar but incompatible connectors. Mismatched tips will prevent charging or damage the socket.

Continuous 45W Output Stability

Under sustained load the adapter maintains its rated 45W output within the specified 19.5V 2.31A limits. The 100-240V input range handles voltage fluctuations without shutting down, so the charger remains reliable during extended work sessions or while the battery recharges under heavy system use.
