  • Accepts worldwide AC 100-240V input for versatile use

Purpose-built 45 W replacement

This myVolts AC adapter delivers 19.5 V at 2.31 A through a 4.5 mm by 3 mm barrel connector. It is designed for HP Stream, Pavilion, EliteBook Folio, Spectre, ProBook, ZBook and Chromebook models that require a 45 W supply with this exact tip size.

Upgrade from worn or lost originals

The unit replaces any 45 W HP charger that uses the 4.5 mm by 3 mm plug, covering EliteBook 820 G3 through G4, 830 G5, 840 G3 through G5, 850 G3 through G5, ProBook 450 G3, 455 G3 through G4, 640 G2 through G5, 650 G2 through G3 and Stream 11 Pro G3 through G4 EE. The jump is worth it when the original brick fails, the cable frays or the connector loosens.

Steady output under continuous load

Rated for 100 to 240 V input at 50 to 60 Hz, the adapter maintains its 45 W output during extended charging sessions without throttling. The 1.5 A input rating keeps mains draw modest while the fixed 19.5 V rail powers the laptop and charges the battery simultaneously.

Questions about this item

What connector dimensions does this 45W adapter use?

How do I connect this charger to my laptop correctly?

Align the 4.5mm x 3mm barrel tip with the laptop's DC-in jack and push straight in until fully seated; forcing it at an angle can bend the centre pin.
