are all micro USB wall chargers created equal?

[B737]

Regarding our Bluetooth pieces, is it safe to say that all micro usb wall chargers will work with all micro usb devices?

what im getting at is can i use a micro wall usb charger supplied with one unit to charge something else? plantronics vs motorola....

because its micro usb my hunch is its a universal standard and they are fully interchangeable.

i tried looking on the wall plugs themselves for amps ect and they have no markings...

I think so,

I charge my iphone and my zune ( yes i had one ), with an wall charger that comes with a chinese product without any problem.

I think that USB voltage is standard so, all the chargers must output the same value.

much appreciated

i found some information on them...
they both output .5 volts

plantroncis charger puts out 350 milli amps
while the Moto one puts out 550 milli amps

im pretty sure all that matters is the .5 volts and the moto will just charge the device faster.

all im doing is using my plantronics 975 charger to juice up the Moto HX1.

You've just named it

The more amps the faster it'll charge your device.

Devices has their own limitations about maximum amps they can take, but I don't think it is a problem with same kind of devices.
