1.2A appliance on 2A ?

First of all, sorry for my English (not my mother tongue) but I do hope it's understandable.



I've just bought a Bluetooth GPS receiver and it has the same type of plug as my Pocket PC. The two devices have pretty much the same AC adapter : the output is the same (5V) but the amperage differs (1.2A for the GPS and 2A for the PPC).



I was wondering whether I could plug the AC adapter of the PPC (2A) into my GPS receiver (1.2A) without risk.



Thanks for your reply, sorry for the rather basic/stupid question and for the average English.

The centre pin on the connector may be positive on one supply but negative on the other. You need to check this.

Otherwise, there is always risk when using a supply on a load for which it wasn't designed.

I would measure the voltages just to be sure - I don't trust labels. But, provided that you check the centre pin polarity, as above, you should be ok.
