Yes, it is better to use a diode (does not need to be a schottky one unless you need this extra voltage drop cause by the normal diode). The diode will ensure that when one adaptor is on, there is no current flow to the others that may cause any problems.
Re: draw double amount of current from multiple ac-dc-adapte
