Compatible Acer models

This 135 W AC adapter replaces original chargers for Acer VN7-592G-788W, VN7-792G, VN7-792G-51K9 and VN7-792G-77WR notebooks. It also covers Acer part numbers NH.G6TAA.003, NH.GTVEK.001, NH.GXBAA.003 and NH.GXCAA.001. The unit is not suitable for 180 W or 230 W systems.

Thermals noise and power draw

The adapter delivers 19 V at 7.1 A for a continuous 135 W output. Built-in overload, short-circuit, over-voltage, over-current and over-temperature protections maintain stable operation. A durable sealed case resists water and humidity while supporting high power efficiency.

Deciding specification

The connector uses a 5.5 mm diameter plug tip without a centre pin. Buyers must verify this exact tip geometry against their laptop before purchasing. The package includes a UL-listed 6 ft AC cord and a 6 ft DC cord for extended reach.

Questions about this item

How do I install the iTekiro 135W AC adapter, and what connector detail should I check first?

Match the 5.5 mm diameter plug tip without a center pin to the laptop's charging port before connecting the 6 ft DC cord to the adapter and the 6 ft UL-listed AC cord to the wall outlet.

What maintenance or replacement will this 19V 7.1A adapter need over time?

The 6 ft AC and DC cords can wear at strain points; inspect them periodically and replace the whole unit if insulation frays or the plug tip loosens.

What power limit appears first if I run this 135W adapter continuously on a compatible Acer model?

The 135W output ceiling is reached before higher-rated 180W or 230W units would be needed, so sustained loads above 135W will trip overload protection.
