Questions about this item

Does the package include both the AC adapter and the power cord, or do I need to buy the cord separately?

The box contains the 135W AC adapter with a 5.5×1.7mm connector and one power cord, so nothing extra is required to start charging.

My laptop needs a 19V 7.1A supply — is this the correct version or is there another capacity I should pick?

This unit delivers exactly 19V at 7.1A for 135W total, matching the A18-135P1A, ADP-135KB T and PA-1131-26 part numbers listed for compatible Acer models.

Will the 135W rating actually power my Predator Helios 300 PH315-51 under load, or does it drop below that in practice?

The adapter is rated for a continuous 135W output at 19V 7.1A and includes short-circuit, over-voltage, over-current and over-temperature protection, so it sustains that power for the listed Predator and Nitro models.
