Review on Nintendo Switch Charger: Fast PD Charging, 5FT USB C Cable, TV Dock Compatible by Lori Harper

Nintendo own brand charger is very expensive but it is always sold out, so I advise you to buy this charger. I was a bit hesitant to buy it at first after hearing about the issues with third party chargers and switches, but it looks like all those issues have been resolved. This charger will do exactly what you need. Charge the switch.
