The switch should let you know if a charger is incompatible or not. I tried plugging it into my Dash Charger because it was the only type c charger near me and the Switch wouldn't charge from it. (Thankfully.) It had a notification that said the charger was incompatible and it wouldn't charge.
All standard chargers should work just fine though.
You only need a good USB cable, the charge be slow but work, i have a Aukey QC 3 18w and works but a little more slow than the original charger from Nintendo.
