Dave,

I own the 4245, and the 4125 supplies, and like them both 
just fine, although the fan in the 4125 is a bit noisy.

The main differences between my 4125 and the 4225 are that 
the 4225 has meters and a cigarette lighter socket on the 
front, just like the 4245. The 4125 has neither. I don't 
care about it not having meters, but do miss the cigarette 
lighter socket. Also, the plastic thumb knobs that hold the 
wires on the output bolts of the 4125 will screw completely 
off, thus allowing for the use of closed ring terminals on 
the end of the cable you connect to it. I am pretty sure 
that the 4225 is like the larger 4245, in that its terminal 
knobs do not come off.

If there are any other differences, they are internal, and I 
don't know what they are.

The 4125 costs approximately $90, and I believe the 4225 is 
around $120.

I have had my 4125 for just about a year, and the 45 amp 
4245 for 3 years.

I wouldn't hesitate to buy those same units again if either 
had to be replaced.
