Has anyone seen a NEMA 14-30 male to NEMA 14-50 female combination extension cord / adapter all in one piece? I know I can buy the adapters and use a separate extension cord, but if possible, I'd rather have one 25 or 30 foot cord, all in one, more reliable. Yes, I also know I can just buy the ends, or buy one end and make the cord, but I'd rather have something manufactured that may be more weatherproof. Thanks.
 
And going from NEMA 14-30 (30 amp socket in the wall) to NEMA 14-50 (50 amp plug) generally isn't a good idea. Even if in your particular situation it is safe (your 14-50 plug is connected to a 16-amp EVSE). bad things happen when mismatches are possible. Going from a 50-amp socket to a 30-amp plug is just fine, the other way around is asking for trouble. Never pull more than 80% of the rated max (24 amps on a 30 amp circuit, for example).
