SKU CH-Q3TJ-8THXF

18.5 V AC adapter with 100–240 V input and over-voltage, short-circuit and over-current protection for HP TouchSmart TM2 series laptops

  • Compatible with HP TouchSmart TM2-1000 and TM2-1070 models
  • Worldwide 100-240VAC input works across regions
  • Fixed 18.5V output matches laptop power requirements
  • Built-in over-voltage, short-circuit and over-current protection
  • Includes power cord cable for immediate use

Compatible HP TouchSmart Models

This AC adapter replaces the original charger for HP TouchSmart TM2-1000, TM2t-1000 CTO, TM2-1070, TM2-1071, TM2-1070US, TM2-1070CA, WA808UA and WA811UA laptops. It includes the power cord cable for immediate use. The unit is brand new and intended as a direct replacement for a lost or faulty power supply.

Output Voltage 18.5V

The adapter delivers a fixed 18.5V output, which must match the laptop's original requirement exactly. It accepts a wide 100-240VAC input at 50/60Hz for worldwide travel use. Built-in safety circuits provide over-voltage, over-current and short-circuit protection. Using a charger with a different voltage risks permanent damage to the notebook.

Installation and Common Issues

Connection is straightforward: plug the AC cord into the adapter, insert the barrel tip into the laptop, then connect to mains power. The most frequent problem is a loose or worn DC jack on the laptop itself, which causes intermittent charging. Verify the tip fits securely before assuming the adapter is defective. This unit is not suitable for laptops requiring a different voltage or connector type.

Questions about this item

What does the 18.5V output mean when the adapter is plugged into my HP TouchSmart TM2?

The adapter delivers a steady 18.5 volts to the laptop, matching the voltage the TM2 series expects so the system can charge and run without triggering a voltage mismatch warning.

The input range is 100-240VAC at 50/60Hz — what does that cap in practice?

It accepts mains power from 100 V up to 240 V at either 50 Hz or 60 Hz, so the same unit works on North American, European and most other household supplies without a separate voltage switch.

Will the barrel plug fit the charging port on a TM2-1070 or TM2-1071?

Yes, the connector is built to the HP specification used on the TouchSmart TM2-1000, TM2t-1000 CTO, TM2-1070 and TM2-1071 models, so it seats securely in those ports.
