Review on KK Limited 20V 7.5A 150W AC Adapter Charger - Compatible Replacement for Asus ADP-150CH B A18-150P1A 0A001-00081500 0A001-00081600 - Suitable for ROG Strix Scar III G531GD G531GT & ROG Strix G731GT - Ideal for ROG Strix G GL531GT by Nick Beck

I had a VERY hard time finding a second adapter for my new laptop that matched the exact specs of the OEM adapter (ADP-150CH B) from a reputable seller (on Revain or elsewhere) and should be shipped from the US (I know it's made elsewhere). ASUS didn't sell it. I was put off reading the fine print or researching the reliability of sites that sell adapters and batteries online. I took a chance with this as there were very few reviews on the seller and they were mixed due to the Revain guarantee. It paid off. This adapter looks a bit different so I don't think it's OEM (it doesn't claim it) but it works exactly the same with no issues and is really cheaper than adapters that claim to be OEM. I am very happy with this purchase and would buy again. If it helps, I have an ASUS FA506I aka TUF A15.
