It is a real shame that all coaxial power plugs couldn't be standard on polarity. The V2 doesn't even show voltage or polarity on
the unit.
IMHO the coaxial connectors should all be for low voltage DC, ground center, and even better would have been color coding for
Who is to blame for this wall-wart mess?

My non-archos charger wasn't clearly coded for polarity. In any case, it
still wouldn't help if the tip and the cable separated, without clear +/-
labelling. I was able to get it right, but with a removable tip, the risk is
I'll muck it up some day when the tip comes off (as it does, frequently)

So I used tip-ex to make a white stripe when the tip was on the correct polarity
which lines up with its sister-mark on the cable. Now if the tip and cable
separate, I can guarantee its gone back correctly.

I also wrote the polarity onto the archos case. Less effective, but useful in
