Best wall charger for Meizu

Hi,
What wall charger is better for the meizu - the one with 500mA or 1000mA output?

500mA is fine, match the specs of the original charger I think and most other things.
Self I use a charger with 400mA and work nice as well.
1000mA may not be necessary because the player may not need more power at all for charging the battery.
