135W 19V AC Adapter for Acer VN7 Series

This 135W AC adapter delivers 19V at 7.1A to power and charge compatible Acer V15 Nitro and V17 Nitro laptops. It fits models including the VN7-591G and VN7-791G with a 5.5mm barrel connector that has no center pin. The unit is new and built for daily mobile use.

Replaces 120W and 90W Original Chargers

This adapter replaces the original Acer PA-1131-05 and lower-wattage 120W or 90W chargers supplied with the listed Nitro notebooks. It does not replace 180W or 230W adapters required by higher-power configurations. The right-angle DC plug reduces strain on the laptop power jack compared to straight-tip designs.

Consistent Output During Extended Sessions

High power efficiency provides continuous power whether the laptop is on or off, charging the battery while the system runs. Internal safety circuitry filters input voltage spikes and limits output voltage or current to protect the notebook from electrical hazards. The ruggedized case is sealed against moisture and high humidity for reliable operation in harsh mobile environments.

Questions about this item

What size DC plug does the iTekiro 135W adapter use for the Acer VN7-591G?

It uses a 5.5 mm diameter plug tip without a centre pin inside, matching the Acer VN7-591G and VN7-791G charging ports.

How do I install the iTekiro 135W adapter and what step is often missed?

Connect the 6 ft 3-prong AC cord to the wall outlet, attach the DC cord to the adapter brick, then insert the right-angle 5.5 mm tip firmly until seated; the step often missed is fully seating the right-angle connector to avoid intermittent charging.

When will the iTekiro 135W adapter need replacement and what should I watch for?

Replace the adapter if the 19 V 7.1 A output becomes unstable, the right-angle DC connector feels loose, the 6 ft cables show fraying, or the ruggedised case cracks from moisture exposure.
