I have a Acer predator (g5-793-72au) laptop and like the title implies I forgot my charger at home. I bought a universal 90w charger That didn't work and one off of Amazon that said it worked with my laptop and surprise it didn't work either. I feel like I'm out of options here, I have found one more charger from a chinese website but Im skeptical and don't want to wait 20 days for shipping.
I wouldn't settle for cheap Amazon/Chinese chargers - you will run the risk of damaging the charging system and the computer itself. The risk is not worth ruining something I'm sure you paid quite a pretty penny for.
It is a time for a battery management. Use your battery efficiently, sync your all passwords with your accounts that you can use on phone. Take a backup of all your meeting and important dates from the calender.
Then find for local computer vendor, or you can take a help of Google assistant to find a right store near you.
