Just got a new home and have a 14-30 dryer plug installed in the garage, but I can’t seem to find a level 2 charger using that plug. Is it safe to just get the $200 chargers on Amazon and get an adapter, or should I keep looking for 14-30 chargers (if so, where?)?
Don't change the outlet to a plug that could draw more amperage than the wiring is rated for; safety and liability reasons. An adapter is fine as long as your are using an EVSE not rated above the outlet. You could also buy a hard wired EVSE, and make your own cord and plug for it. Or get a Tesla, they have an adapter for nearly every outlet out there. Model S/X/3 Gen 2 NEMA Adapters
Just to clarify, the charger is built inside the car. The box on the wall or pedestal, along with the cord and connector, is a charging station or electric vehicle supply equipment EVSE. Is it worth the money to you to increase the rate of charging to 2 hours for a full charge? Will that be a money saver for you or reduce gasoline usage even farther for its own reason? If not, there's no point in buying the charging station.
You can buy adapters for that, or make your own. I've been messing around with bunch of different things, and finally settled on three components: * a 10' dryer cord with a 3-pin 10-30P plug on one end and crimped wire connectors on the other; ($16) * an L6-30R receptacle that I put on the other end of the dryer cord; ($16) * a SIMBR Generator Cord Adapter that has an L6-30P plug on one end and three normal 120V type receptacles molded into the other end of a 1 ft wire. ($16) Total cost: < $50. I went with the L6-30 connectors because they're rated for 240V 30A although we only need 12A for this (so an L5-20 or L5-30 would probably work fine as well). These style connectors seem to be popular for welding equipment, and generators used with RVs. I also picked up a large electrical box at a recycle store for about $40 and mounted it on my driveway wall, and put the EVSE and plugs inside of it. It locks. The Prime's EVSE plugs into it and it works perfectly.
