Has anyone purchased the $800 bundle of UMC charge adapters? Also is this the most cost effective way to have a versatile connection, meaning would I really use all the 9 adapters that's in the bundle or would only 3 or 4 adapters really be ideal and necessary like the NEMA 14-30 and NEMA 6-20, etc...
