Milli-Amps, How Close is Close Enough?

What does it say on the unit itself?

As a rule of thumb, you want your power supply to have a higher mA rating than your unit. If the unit says it draws 300 mA, then a 500 mA power supply will be fine.

 

It will not hurt to have more so get as much as you can.

 

The unit will only draw as much as milliamps as it needs. You can always have too much but not too little available.

 

The link you cited says that the power adapter puts out 500mA, but that doesn't necessarily mean that the unit draws that much (and probably doesn't). As others pointed out, delivering more current than the effect needs is not a problem, so if you've seen a lower number cited somewhere else, that certainly could be the case.

 

You really want to power it with a generic wallwart ?
It's 4.5V, not your standard PS, you might have to buy the official one.
Batteries last forever, I haven't changed mine since last year while using it every now and then.


Fantastic little unit btw, I have gigged with it (bar gigs, into the PA).
It's definitely better sounding than my Boss GT3 GT5 & GT6 as well as the early POD I had.
Nowadays I use pedals + tube amp but it's still in my bag as backup while my Tech21 stays home.
