HP HSTNN-DA12 230W power adapter

This 230 watt AC adapter delivers 19.5 volts at 11.8 amps for compatible HP devices. It accepts a 100 to 240 volt input at 3.5 amps across 50 to 60 hertz. The barrel connector measures 7.4 by 5.0 millimetres. A power cord is included in the package.

Replaces lower wattage chargers for Thunderbolt

The adapter is manufactured for the HP USB-C Universal Thunderbolt G2 HSN-IX01 Docking Station among other hardware. Upgrading from a lower rated supply is worth it when the dock or laptop draws more power than the original brick can provide. It prevents throttling or shutdown under heavy peripheral loads.

Limited to barrel connector devices needing 19.5V

The fixed 19.5 volt output and 7.4 by 5.0 millimetre tip restrict use to hardware designed for that exact voltage and connector. It cannot power USB-C only laptops or devices requiring a different voltage. The 230 watt ceiling also caps the total load for high power docking scenarios.

Questions about this item

Does the 7.4 x 5.0 mm connector fit my HP USB-C Universal Thunderbolt G2 HSN-IX01 Docking Station?

Yes, this adapter is manufactured for that docking station and the 7.4 x 5.0 mm tip matches its power input.

What is the correct order to connect the 230W adapter so the 19.5V output starts cleanly?

Plug the power cord into the adapter first, then into the 100-240V 50-60Hz wall outlet, and finally attach the 7.4 x 5.0 mm tip to the docking station.

When should I replace the power cord that comes with this 230W adapter?

Replace the cord if the insulation is cracked, the plug pins are bent, or the connection at the adapter inlet becomes intermittent.
