jwagner010 Posted October 23, 2022 Posted October 23, 2022 I have a Nema 6-20R, is there such a think as a USB charger that plugs into a Nema 6-20R?
KeviNH Posted October 24, 2022 Posted October 24, 2022 Never seen a USB charger mated to a NEMA-6-20P, 20A/250V seems like overkill for charging your phone?
tmorse305 Posted October 24, 2022 Posted October 24, 2022 You could use something like this and make an adapter cord. https://www.amazon.com/Anigaduo-European-Adapter-AirPods-Charging/dp/B09WMK1RP4/ref=pd_day0fbt_img_sccl_1/145-0335246-2514639?pd_rd_w=IEofB&content-id=amzn1.sym.9b14949a-3979-4b7d-b182-b07adcc4c0e7&pf_rd_p=9b14949a-3979-4b7d-b182-b07adcc4c0e7&pf_rd_r=RRYM6ME73554ZYHSXJY9&pd_rd_wg=6L4bS&pd_rd_r=79141ca7-e071-41b7-888a-57eb0c385fbb&pd_rd_i=B09WMK1RP4&psc=1 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.
MrBill Posted October 24, 2022 Posted October 24, 2022 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 1
apostolakisl Posted October 24, 2022 Posted October 24, 2022 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¤cy=USD&msclkid=5fd88992aaaf16b8de51eac5a43da32a
jwagner010 Posted October 29, 2022 Author Posted October 29, 2022 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. 1
apostolakisl Posted October 29, 2022 Posted October 29, 2022 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.
