That''s an interesting one and would need a study to be confident it is a non-issue. Depends on what ''long'' means. As batteries get bigger and if daily mileage remains on average about 24-28 miles a day then an outage of up to a few hours is not likely to trigger a huge demand due to a backlog of charging demand.

Is using the wrong mA on a power supply dangerous?

The short answer is yes, it could be dangerous - but probably only to the power supply, not your equipment. Lets say you have a 500mA load and you attempt to use the 250mA adapter, then you will either overheat the 250mA adapter, or in the worst case, the transformer core in the adapter will saturate, cause large pulses of current to be drawn during the peaks of
