How important is amperage when charging?

[Jonny Kansas]

I've got a radioshack Bluetooth speaker that I got for Christmas last year. It only came with a micro USB to USB cord for charging.

For input, it says 5v & 500mA

Will it blow it out if I use a phone charger who's output is 5v & 1A?

Im guessing so, but I really hate that I have to fire up the laptop to charge this thing. I'm cleaning out my garage & didn't want headphone cables in my way.

I can't be absolutely 100% on this statement but I have used higher AMP chargers on devices that specified lower AMPs (and voltage) for a long time and either the charger adjusts or the device adjusts to use what it needs. I've never burned out anything. I have a 2A 15v charger for my tablet that I have used on phones without an issue.
YMMV.

Thanks for the input. You're a braver soul than me without scientific confirmation that it's OK. Haha

It seems that the current generation chargers won't output more than what is being asked for. Using that 2A 15v charger is fairly common for other devices on another forum.
