For example, you can connect a 300mA pedal to a 200mA output, without causing any problems. The important thing is to not exceed the total of all the labels. With a CS7, the output labels add up to 1900mA total.
Excellent isolated switch mode power supply. With a total capacity of 1900mA you will be able to run a good number of pedals off this reasonably small device. It just does the job well. Recommended!
