Think I know the answer to this but just want to check.
USB chargers seem to quote their output in amps whereas devices have their requirements in watts.
Looking at the one in front of me at the moment, I assume that 5V @ 2.4A translates to 12W so for something with a min requirement of 15W I assume it either needs a charger with a bump in voltage (which you won't get as USB is all 5V?) or the amps?
