Perhaps I'm being dense, but seeing as the "charger" isn't hardwired why use it at all? Just build a 14-50R to 3x whatever the American mains plug is called and swap to that whenever you want to charge the bike. Or you could streamline it even further and go 14-50R to 3x IEC C14 to go straight into the bike and quick chargers.
Thanks for that idea! I agree that a cable would need to be built.
I have one of these though the voltage for the four 5-15R receptacles is 120 and not 240. https://www.amazon.com/MECMO-Distribution-Adapter-Household-Generator/dp/B0BQVR5CML?ref_=ast_sto_dp
Merlin, what I did is, the basic charger, the J-1772 has a 14-50? is it, the 4 prong 50 amp basically dryer plug. From there, if you are handy with a screwdriver and essentially wire strippers, get yourself some 10 Ga wire and make pig tails to change the plugs. Just a female of the main charger on one end, and then on the other end, all the different male sizes. The overall pigtails you make is maybe a foot long if that, very small. I have 4 of them which I keep with my charger on the bike. That way, no matter where I am at, if they got a plug, any plug, I just pigtail to match THEIR outlet, and plug my charger into it. if you are at a friends house, restaurant, wherever, hey, can I borrow your dryer outlet for a few? can I borrow your AC outlet?, Let me borrow your tig / welder outlet?, water heater outlet? ANYwhere there is a plug, you just grab that one foot long (but twistable into a loop cause it IS wire, and easier to store), adapter, match your charger's plug and away you go!
I used 10 ga because while 12 ga can handle it, the 10 gives a bit more leeway, especially if people may walk on it, it's setting in the hot sun etc, and it's not THAT much more thicker. I ended up actually making about a 40 ft extension cord. My one friend lives in an apartment and I run it around the corner, into the window and into the laundry room to grab an outlet to charge
If you goto someone's house, yes you can probably find 115 volt (usa) right at the front door or right in the driveway, but if you want a decent charge rate at 240, the ext cord helps get to where THAT plug is at.
It all fits nicely into one bag, and leaves room in the bag still for other stuff. If you are going on trips, yes one should plan their stops to accommodate fuel needs but it's also fun to be able to grab a juice up 'anywhere along the way' too! If you are wanting to do multi chargers, whatever your situation is, you can easily adapt and make it very portable as needed.
