FWIW I've charged my Model 3 on my parent's EO Mini Pro and it worked absolutely fine, charged at the speed I'd expect etc.Just a heads up that there has been issues with EO and the Model 3. My charger didn't work with the car, nor did the brand new replacement, so ended up with the Tesla unit.
I believe EO have now stated they've fixed the issue, but might be worth clarifying that before handing over any money.
