There is a somewhat portable DC quick charger that charges at around 10kW. Weighs about 40 lbs and can fit in the trunk of the Spark EV. You can't keep it in the trunk when in use though as it needs ventilation. It's basically an AC to DC converter with smart features.
You can get it with a CHAdeMO or CCS Combo plug or a higher model with interchangeable plugs to use both.
The input is J1772 female connector so you can connect to regular Level 2 charging stations. Or can get a NEMA 14-50 adapter and charge at RV parks.

This is a US reseller but I have been in contact with the manufacturer which I will remain nameless.
Some Spark EV users have already been using it in the USA. I've never seen one here in Canada.
But the only problem I see at the moment is it's only CE certified (like many aftermarket EVSE) - which is a self-certification mark.
It does not have UL, ETL, or TUV electrical certifications which are usually required for North America.
Level 1 and 2 EVSE with CE mark only might not be too much of an issue as most of the communication and limitations is done by the car's BMU but I'm a little bit skeptical Level 3 charger without recognized electrical certifications.
