Yes - your device can draw that much but if it approaches that figure or 
the max of the power supply  you will get voltage drops and heating so 
it may deliver 400 ma but the voltage will drop significantly and the 
transformer will start to do a smoke test.  It's best to get a larger 
power supply.  That's assuming that the supply is unregulated (cheap) as 
most of the power cubes are.  A regulated supply (expensive) will 
deliver a constant voltage at some current rating or another.  If you 
exceed the specs of the regulated supply, typically the circuit breaker 
will trip.

Feel the power cube.  Un loaded they may feel slightly warm but should 
never be uncomfortable to the touch.

FYI - If the rating is in watts then at 110 volts 1000 watts equals 
approximately one amp so you can figure out the total load of your amps 
and devices by adding up the loads (in watts) and divide by 1000.  
That's not entirely accurate but it's close enough usually.  The formula 
is volts x amps = watts  and volts (110) divided by watts (1000) = (1.1)amps

Might keep you from blowing a fuse some day.

Since we are into electrical.  Watch your mikes and water.  A minister 
day before yesterday in St. Louis was about to baptize  someone and 
reached for the  mike.  He was electrocuted in  front of  everyone at 
the service.

I've had them bite me a time or two on wet ground.  Get an extension 
cord with a good ground and a ground circuit interrupter built in.  I've 
been looking for one but have been unsuccessful so far.  I guess I'll 
buy one and build it into a box to plug in.
