18.5 V AC Adapter for HP TouchSmart

This 18.5 V AC adapter powers compatible HP TouchSmart notebooks including the TM2-2057 and TM2-2151 models. It accepts a worldwide input range of 100-240 VAC at 50 or 60 Hz for international use. The unit is brand new and includes over-voltage, short-circuit and over-current protection. It serves as a direct replacement for the original power supply.

Included Power Cord and Safety Features

The package supplies a detachable power cord so the adapter is ready to use out of the box. Built-in safeguards protect the laptop from voltage spikes, short circuits and excessive current draw. These protections operate automatically without any software installation or user configuration required. The adapter is tested before shipping to confirm correct output.

Barrel Connector Polarity and Voltage Limits

The adapter delivers a fixed 18.5 V output through a barrel connector that must match the laptop's polarity and diameter. It cannot charge devices that require a different voltage or a USB-C Power Delivery profile. The 100-240 VAC input covers most mains supplies worldwide but does not support DC sources such as vehicle or aircraft sockets.

Questions about this item

How often will the power cord need replacing?

The cord is a standard IEC C7 figure-8 type; replace it only if the insulation cracks or the plug loosens.

What limits continuous output at 18.5 V?

The adapter is rated for 18.5 V output with over-voltage, over-current and short-circuit protection that will trip before components overheat.

How hot or loud does it get when left on all day?

It runs silently with no fan; the enclosure warms to a safe touch temperature under normal 100-240 VAC input.
