Review on Premium 180W AC Adapter Power Charger for Acer Predator Helios 300 Gaming Laptops PH315-52-78VL, PH315-52-710B & Triton 500 PT515-51-75BH | Aspire V Nitro Series Compatible AK.180AP.010, AK.180AP.020, KP.18001.002 by Issac Smart

I'm a little picky about adapters as bad adapters can damage your device, get very hot or pose a safety hazard. It's an expensive replacement but I bought a UL certification which most others don't have. I use it alongside the original and there is no difference for my predator. It doesn't get hot, runs fast and fits great. What else is there to ask.
