Higher amperage USB port

[Sheriff420]

This is about the eGo charger.
The plug is 100mA input, 5v/500mA output.
The part that connects to the battery is 5v/500mA input, 4.2v/420mA output.

I have a dual USB adapter (the part that plugs into the wall) and it is 0.4mA input, 5v/1000mA output.

If I connect the eGo charger to this universal USB adapter, will it harm the batteries.
I assume the eGo charger will reduce the 1000mA input from the adapter down to the 420mA that it puts out but I'm not sure.

That would be correct

Good to know.
I ordered a new charger the other day and I think it just has the USB part and not the wall plug part.
