Question about power supply...800mA too much?

I just purchased a Dunlop Smart Gate for my electric guitar and it is powered either by a 9 volt battery or a 9 volt power supply. Here's the thing. The instructions state that a 9 volt power supply of 20mA or greater will work. However, 800mA is one that I have right now, but 800 is a big jump from 20. I know zero about electronics. Will the 800mA adapter toast my Dunlop or am I okay to use it?

Thanks
 
you will burn up the electronics if you do not use the correct power adapter

you can get the right adapter from radio shack just take the appliance with you if you are not sure what to get.
 
800ma is the capacity of the power supply. The pedal will take only what it needs.

But you need to check if the pedal wants AC or DC, how many volts, and what polarity it is if it's DC.

And see if the tip fits.:)
 
+2

If the power supply were smaller than spec'd, you'd over work that supply and eventually cook it.

The bigger supply will run cooler and will likely last longer than the whimpy 20mA unit. Just as long as the voltage and polarity is correct, you're fine.
 
A Electroncs curcuit only draws as much Power as it needs (accept for some very specic applications that require current limiting like some Battery rechargers)...so you can use a 800ma addapter, but as other have stated make sure you need AC or DC and the the polarity on the Adapter is the same as the unit you are powering...
 
It says I need 9 volt AC which is what I have. So if it is only going to draw from the 800mA what it needs, I guess I'm good to go. Thanks for all your input.
 
Also you don"t need to worry about polarity with AC adapters....
 
Minion is right but from reading the original post, I thought you said 9 volts...DC :confused:

You've never seen a 9 volt AC battery before??

Drummerbones... I'd check those specs again
 
It needs 9 volts DC not AC:

Power: Single 9-volt battery or optional Dunlop ECB03 AC adapter

OK... you made me look... It's 9 volt Dc... the AC adapter converters the 120 volt AC to 9 volt DC

unless the circuit is a short circuit.....;)
Personally, I'd prefer a lower current adaptor for a lower current device.
 
9V DC, 200mA, center negative.

The one you have won’t work because it’s AC.

:)
 
.......because if you leave it on when you're not using it, the bigger AC adaptor is going to draw more idle current, and even when in use it will be less efficient, assuming it's an older one, not a new switcher adaptor. If the Dunlop adaptor is a switcher, vs an older and overrated wall-wart, the difference will be even bigger. Eventually it will eat away the savings of not buying the lower power one, and will plummet the earth into a global warming catastrophie. :eek: :D
 
......plus it's gotta be something about hyperspace or wormholes.
