GTone"watts can back it up" is easy to determine via the UL rating. Ergo, declared "amps" is part of a larger analysis of the device.
"will want to charge at close to 16 volts" I sense confusion? 16v is the nominal target voltage of a 4s, while you charge you are pushing amps. Yes your math is right, but subjective in the system. w = v * a is correct, but IR (load) is huge, a product of the system -- mostly battery. A firehose does you no good when you have a drinking straw in the the mix.
Depending on the quality of your battery, tolerance for abuse or how high your >> amp << rate is for the charge, and the integrity of the charger you need to remember how the numbers are not black and white. On top of that consider the watts available for the power supply (AC) to support the charge. Things are not quite a one-to-one analysis. My EE is rusty on AC TBH.

It seems this charger is more in line for charging drone packs which are typically a lot smaller in capacity.
