Canon Canoscan Lide 30 and Laptop

I'm about to purchase the Canoscan Lide 30 for use on a laptop. However,
since this scanner gets its power from the USB port, I'm worried about

a) not enough power for the scanner through the laptop's USB port
b) the scanner draining the laptop battery

Should I get a scanner with an AC power supply, or should I not worry about
power consumption?

TIA.

 

I have the Canoscan N600U (or something like that). It also draws power
from the USB port. I have never had any problems using it with my laptop.

In terms of power drainage, I don't know how fast it will deplete your
battery.

The only issue I have heard of with the Lide 30 is that it is relatively
slow and noisy.

 

It's bound to take some of the laptops battery. There's no free ride, but
I'll bet your scanning will be in the house where you'll have the laptop
plugged in. If thats the case,, as is mine,, no problem. I just bought the
Lide50 and am impressed. I got it as a 2nd scanner for traveling in by bag
with the laptop. I was really surprised with the scans. My primary scanner
is an Epson Perfection 2450 photo and the Canon puts out more natural
looking skin tones. You might want to consider the Lide50 'stead of the 30
because of speed. That is if you have USB2.
