Unfortunately, no. Chargers vary in power consumption/output.

But you could generalize: it's likely that the max power used by a 110v charger is 20A * 110v = 2200 Watts. (Assuming 20A is the max common breaker size on 110v circuits).

The time spent waiting is only determined by how fast your batteries charge.
That's about it. Should say however, that at least with lead-acid batteries, you can get an 80% charge much faster than you get 100% charge. Meaning: much more time is spent going from 80-100% than getting to 80%.

I'm waiting for Paul to chime in again. He's talking about a 6kW genset. So obviously he has other plans than my example. His & todayican's examples are examples where the genset can theoretically provide all the juice the electric motor needs to propel the car. So they could drive indefinitely (or until the gas runs out) :P

But I think my example is close to what I think you were asking: "could I theoretically go to the hardware store right now, buy a portable generator and connect it to my existing battery charger, effectively making the car a plug-in hybrid in 5 minutes?" Answer: yes, with the limitations that you get.
