Except for the slightly thinner and flatter design, the new Galaxy S9 wireless charger shown in the user manual will sport similar design and functionality from its predecessor.
There were three coils in the earlier model but the new wireless charger seems to include only two coils stacked on top of each other. The new charger also includes the same fan which starts automatically when the device reaches higher temperatures.
It supports 9 volts and 1.67 amps maximum input power, that provides the charger 15 watts of power.
The new wireless charger priced around €75 ($90) is expected to be available along with the Galaxy S9 in black and white colors on February 25 in Barcelona, Spain.
