my celestron is powered with a transformer from dick smith. it has variable settings to 12 V and those pos to pos and pos to neg adapters. it is connected to an outdoor socket on my deck and i do not find cord wrap a problem. and it has in-built house electric safety features when you do something 'dumb'...

The risk of accidently shorting out battery terminals is very remote, since they are so far apart. I have used battery power for 30 years and have never had it happen. And you will not get a shock if your hands touch the terminals.
Most people seem to prefer batteries because there is no danger of overloading the mount electronics-no power spikes, etc.
