Any one know what approximate tolerances are on these things please?

I have a laptop without an adapter which takes a 19 volt 3.2 amp
adapter. I have a 20v 6.5 amp one and wonder how much damage it will
do to the laptop if I try to use it?

The unit does not have a battery to charge so this adapter will likely
be plugged in a lot of the time.

A tolerance of at least 10% would be reasonable, so 19.0 + 1.9 = 19.9

That was 20.9, when I went to school ... *;-)

which is almost 20V. * 20V - 2.0 V = 18V for the minimum on the 20V
supply, so you should be just fine.

New math.

Actually I see the maths differently, though given the responses which
say that it is OK and has been shown to be OK over a few-year period,
the result is the same: If a laptop takes 19 volts, can I use a
converter over a prolonged period which could put out a continuous 22
volts?
