Using a different AC adapter?

busfahrer

Hi,

I hope this is the right kind of place for a question like this:

I have a device that needs to be charged, and the included AC adapter's specified power output is 5V/0.7A.

I don't know much about electrics: Are the 0.7A always delivered by the power supply, or only a percentage of that, depending on what the connected device pulls out of it?

I ask this because I was wondering whether using an AC adapter that is specified as outputting 5V/1A could be used for charging the device, without damaging its batteries in the long run.

Greetings,

0.7A is the maximum rated output current, so using a 1A power supply will be okay.

Just things to double check before switching adapters:

* Plug type - make sure it's the same plug type/size, so that you have a good fit
* Polarity - make sure the two power supplies have the same polarity (see symbols from Wiki here)

That's good to know, thank you! :-)
