USB Charger for Nema 6-20R

[jwagner010]

I have a Nema 6-20R, is there such a think as a USB charger that plugs into a Nema 6-20R?

Never seen a USB charger mated to a NEMA-6-20P, 20A/250V seems like overkill for charging your phone?

You could use something like this and make an adapter cord.

I'm assuming that it's 240V so you DON'T want to make an adapter cord to a regular 110V outlet.  Using a European plug will avoid that.

Nema 6-20 is 240V and ground.  No neutral.  

Most Chargers are good for input volatge 100-240, so if you find that on the label that part is not a problem. The pin configuration of a 6-20 is such that someone can't accidentally plug in a 125v only device.  So an adapter for 6-20 to 5-15 if it exists would be dangerous to use, someone might use it to plug something else in.

You could perhaps get a corded charger which has a wide range of input voltage: and then either find the correct cord with a molded on NEMA 6-20P plug, or optionally cut the 5-15P male off the cord that comes with the charger and replace it with a 6-20P plug.  (those chargers actually come, or at least they used to, with 2 cords American and European which makes them great for travel usage.)

Good point -- they do make compact adapters which go from NEMA-6-20P to Euro-style  sockets, then you could plug in a "Schuko" 240VAC rated charger

I truly doubt you will find a purpose built device.  6-20R is very rarely used (I actually have one for my home for my central vac) and when used, it would virtually always be installed for a specific device that would always be plugged into it (like my central vac).  So, who would make the plug you want . .. no one.  In short, you would have to cobble something together yourself.  @KeviNH seems to have the most streamlined option.  If it were me, and I needed to charge a phone where I didn't have the right plug, I would just use the external battery packs.  They don't cost that much, charge your phone at warp speed, and have the added advantage of traveling with you when desired.  A fully charged external battery like the one I have can fully charge my phone a bunch of times and charges much faster than even the fastest wall adapter.  This is the one I have.  https://www.anker.com/products/a1271?variant=37436932554902&currency=USD&msclkid=5fd88992aaaf16b8de51eac5a43da32a

Thanks guys, sorry for slow response, work and family commitments have been crazy.  Lots of good suggestions. I actually want to use it to power a sensor behind a HVAC unit.  I ended up going a different route, powering the sensor off the hvac unit with a 24VAC to DC converter.

I had a similar situation where I opened it up and hard wired the usb adapter to 240vac.  It was for a temp monitor in a walk in freezer that was powered by 240.
