I'm looking to replace a damaged 12V 1A DC power adapter for a piece of

12V
1.5A DC (came from another piece of equipment). Is this safe to use as
a
replacement - i.e the current output of new one is higher than old one,
does this matter?

The 1.5A is the maximum it can provide, the equipment will only draw
what
it actually needs, is the polarity of the connector correct? was the
original regulated or unregulated? ditto the replacement?


thank you both for your help.

How do I check the polarity of the connector and whether its regulated or
unregulated.
Both are black power-brick type adapters. Original was from a Belkin
switch
and my proposed replacement is from a network camera, so they are for
similar products.



Have a look on the power supply it should show the input and output ie 240v
in 12v out and a little sign indicating a line and another line with a semi
circle&line informing you of its polarity +&-

Most power supplys are regulated nowadays so dont worry too much because if
its not stated on the outside of the supply you will need a meter or opening
the PS to detect what it is.
