I have access to a free 208V 30 amp circuit at work, but it's a nema 6-20. Two hots and a ground. The OEM charger comes with a nema 5-15 (hot, line, and ground) and a 14-50 (two hots, line, and ground). The OEM charger is rated for 120 to 240V.

I found the sketchiest 6-20 to 5-20 converter (lol) or I could use a 6-20 to 14-50. The 6-20 to 5-20 would be the most convenient, but I'm wondering it would throw an error using 208 without a line.

Any insights? I'm thinking it wouldn't care, but I just wanted to check.
