Review on EMallee Charger Dock 2 Pack for Galaxy Watch 4/3: Compatible with Samsung Galaxy Watch 4 Classic, Watch 3, Active, and Active 2 - Essential Accessories by Seth Bushey

Charging function works well. It seems to take about the same time to charge. One of my units has overheated. This is a major design issue as the design places the back of the disc on the bearing surface and traps heat. In the original Samsung charger, the coil is placed perpendicular to the surface where it can emit heat into the air by convection and radiation. To avoid overheating, simply cut out a two or three inch square of aluminum foil and place under the charger as shown. Picture. This removes heat from the charge puck where it can be safely dissipated, keeping the puck temperature within a safe range. It shows good watch design practice that this overheating is recognized, reported and acted upon when it is too great. Please note in the picture that the watch first complains that you are not using the original charger. Don't worry, the watch will be fully charged. As for that small fixable issue, I'm happy with the value for money these chargers offer.
