HP-Compatible 30W USB Power Adapter

This 19V 1.58A USB AC adapter replaces HP part numbers HSTNN-DA21, 594906-002 and 594913-001. It suits owners of compatible HP laptops who need a replacement or spare charger. The unit includes a detachable power cord and accepts 100-240V 50-60Hz mains input. Buyers whose laptops require a barrel-style connector cannot use this adapter.

Output Specification Decides Compatibility

The adapter delivers exactly 19V at 1.58A for 30W total output through a USB plug. Your laptop must list 19V and 1.58A (or higher current at 19V) on its original charger label. A lower voltage or insufficient current will prevent charging or cause instability.

Simple Plug-In Installation

Connect the supplied power cord to the adapter, plug into a wall socket and insert the USB connector into the laptop. The only common issue is selecting a cord with the wrong regional plug type; the package supports EU, US, UK and AU standards. Verify the USB plug fits your device port before purchase.
