Stock charger amperage?

[Tron]

Just curious if someone from the US can confirm: I currently use the stock charger on a 120V outlet, and it seems that is capped at 10A, resulting in a 1.2kW charge.
I mean, that's enough to get it back to full overnight, I was just wondering since most aftermarket single-phase 120V chargers supply 12 or 15A.
I have one of those incoming, I found out that my garage outlet has a 20A breaker and nothing else except some small lights are on that circuit, so that should be safe to do.
The stock charger will then go into the underseat storage for emergencies.

Thx!

I don't think it's the power cable which limits, it's the vehicle itself. The thing we colloquially call the charger is not in fact the charger at all. It's just a fancy extension cord with some safety logic. The actual charger itself is inside the scooter, and this is factory set to 10A unless you have the quick charger.

So if understood correctly, unless you have the quick charger your only option to charge faster is with 240V instead of 110V.

I have the quick charger and I have set the bike to charge at 12A. Still charges with only 10A from the BMW charger.
I'll see what the aftermarket one I have incoming does (or try a public Level 2, which should be able to go up to 240V/30A).

Ah, that changes things! I have the stock charger (not stock charger cable) so even when I'm on a public Level 2 station charging doesn't go past 10A.

That is not surprising. I suppose you can't even set the amperage on the bike higher than 10A (not sure if the software is smart enough for that, though)?

Exactly right, I'm limited to 10A inside the scooter's software.

I can go up to AFAIK 30A, but again, the BMW charger will only deliver 10 max. I'll see if the 12A charger I have incoming will do the advertised 12.
But it's clear that the CE04 was made for use in Europe, with 240V mains the 10A charge twice as fast as over here with 120V.
Meaning the 4:something hours for a full charge is twice as long here. Assuming the battery is completely empty, you'd need to charge 8.5kWh. 10A@120V makes 1.2kW, or a bit over 7h, losses not included.
Sure, for overnight charging that's still fine, but for a quick top-up on someone's outlet, that's noticeable.

For instance, I envision using it to go to the range to shoot clays with friends. That's 90mi there and back. So not done on one charge. We usually spend around 3h, so that gives me roughly 3.6kWh, or approximately 30-35mi range. Nowhere near a 80% charge which 10A@240V would give me.

If you can find a L2 charger somewhere along your ride, it would get you the quick top-up you need!

I'm new to this whole electric vehicle stuff, I admit, but I'm trying hard not to do an extra stop and having to kill time just for charging ;-)
But L2 chargers are not that plentiful around here, mostly at hotels and some car dealerships. But yes, half an hour @240V/30A would get me half a battery charge.
