40 W AC adapter for select Eee PC models

This 40 W AC adapter supplies 19 V at 2.1 A through a 2.5 mm × 0.7 mm barrel connector. It replaces a long list of ASUS part numbers including EXA0901HX, AD6630 and ADP-40PH. The unit accepts 100–240 V input at 50–60 Hz for worldwide mains compatibility.

Replaces multiple OEM part numbers for direct

The adapter matches the electrical ratings and connector dimensions of the original chargers supplied with the Eee PC 1005HA, 1008HA, 1101HA and 1201HA. Buyers can swap the old brick without modifying cables or sourcing a separate tip. No additional software or configuration is required.

Fixed 19 V output limits use to compatible 40 W

The single-voltage 19 V rail cannot charge laptops that require 20 V or higher-wattage inputs. The proprietary 2.5 mm × 0.7 mm barrel prevents connection to USB-C or other barrel sizes without an adapter. Buyers needing adjustable voltage or higher current must choose a different power supply.

Questions about this item

Will the 2.5mm×0.7mm barrel connector wear out and need replacement?

The 2.5mm×0.7mm connector is a standard passive barrel jack; it has no moving parts and does not require scheduled replacement.

What limits continuous output when the adapter runs at 40W for hours?

The adapter is rated for 19V at 2.1A, so 40W is its maximum continuous output; sustained loads above that will trigger protection.

How hot or noisy does the 19V 2.1A brick get during all-day use?

The unit is a sealed switching supply with no fan; it runs silently and warm to the touch, which is normal for a 40W adapter.
