Why do you say that it has to be "<2A current"? The current specification of a charger is the maximum
current that it can supply - the device that's being charged will decide how much current it "wants". If the device only requires 1A to charge, it doesn't matter if the charger is 2A or 20,000A - it will still work just fine.
