Not sure, the same time I got this set up stark changed the scale from 10 amps to 3.3 kw max looked up a conversion chart and looks like rocket science ! Someone said it could be there way of hiding they have had to reduce the charging rate because of overheating.... who knows.
I don't know how much a generator weighs but I strongly believe that the day of the trackday physical efforts, especially before the riding is over, should be avoided, so I like the idea.
There is a document named Stark VARG - Specification sheet in the Stark's support section of their site, according to which the output voltage of the charger is 210V-430V and its maximum output current is 10 amps, so the 10 amps stated previously in the Varg app apparently were the ones going to the battery and not the ones taken from the electricity supply; after all, otherwise someone charging at 110 V at a certain amperage would have actually charged way slower than someone charging at 220 V at that same amperage. 10 amps • 330 V, which is included in that aforementioned range, = 3.3 kw. I personally live in Italy, where, in our houses, we can get a maximum voltage of 230 V and the sockets are rated to withstand a maximum of 16 amps, which yields 3.7 kw. The Shucko, or type F, plug of the Varg charger is rated for something similar, so we would not be able to get more than that from the socket anyways and probably that's already what we get, because 3.3 kw going into the battery is probably something more, like 3.7, after some losses have reduced the value. Another thought that validates this is that Stark has always stated, as far as I remember, that the Varg can be charged in two hours and in order to charge a 6.5 kwh battery in 2 hours you need roughly 3.3 kw.

If you have any electric car chargers in the area get an adapter then just plug into the car charger. I was looking at generators for a while then realized there are car chargers everywhere and charge from 20% to 100% in two hours. Cost me $2.14 to charge. The adapter on Amazon was $49. Best purchase ever!
Please post the link and/or pictures of this adapter.

Anyone?!
Search Amazon for J1772 to nema adapter.
Thanks I'll get one, do you know if with such an adapter it would charge quicker at a fast charging point?
NO, the "fast chargers" are DC, you don't want to try that, but it wont work anyway.
I posted this voltage converter, and did not dive deep enough into it at first. If you go to Amazon and search 120VAC to 240VAC Voltage converters, you will find a real variety. Price for 5000W for $96 to $189. They all seem to be the same basic unit. (You can determine by the weight the amount of copper wire in them. ) That is all these are is a step-up or Step down transformers. They rate them at 5000w or 120V about 40A, but only come with a 120V15A plug and cord. They say to buy 50% higher than needed, for startup surge. which makes sense, especially with our chargers, which act the same as a modern mosfet welder (They mention these in some of their information). These devices have a large bank of capacitors that take a huge surge to fill instantaneously at plug in, and then run at there rating. You have all seen the sparks when you plug these guys in. But still if you are running a Stark charger at 240V 14-15A, that is about 3300W running, with a 120VAC input to the converter, that is 30A. The power input cord is not made for that current, nor is the plug, they melt. I have a 3500W 120V generator, and it has an RV 120V 30A plug, and they get hot on my RV. So if you look at all the specs, they put fuses on the converters, and fuses will be blowing with these loads, or more importantly these surges. Maybe a slow blow fuse might last, but a circuit breaker might be the best, and some do have that. You can get variable time constant Slow blow breakers, but none of these come with that.VEVOR Voltage Converter Transformer, 5000W, Heavy Duty Step Up/Down Transformer, Convert from 110 Volt to 220 Volt and from 220 Volt to 110 Volt, with US Outlet EU Outlet 5V USB Port, CE Certified | VEVOR US
