I want to connect several power adapters in parallel to increase the capacity.
This is the power adapter;

This one connects to a small lamp and one adapter has sufficient current just for a single lamp. I want to connect several of them in parallel so I can run two wires and tap each lamp into that instead of running separate wires for each lamp.

Can these adapters be connected in parallel the same way the batteries are connected in parallel? Are there any issues? Not even sure if the output is AC or DC here. I guess it is AC because of the symbol after 12V. I've seen some amazing electrical projects from some of you guys so I know some people here have an in depth knowledge in these stuff. So please help me out.

Mods, This is a non-S2k issue so if it does not belong here please move it to the right place. I couldn't think of a better place on S2ki for this question

Thanks
