This dock recharges my Samsung Galaxy S3 (equipped with loading cover Zens ZESHS3P / 00) without problems on. The heat generation is even lower than with the charging station from Zens (ZESC02B / 00). However, this station is obviously not compatible with the compact camera Pentax WG. 3 Taking this to the charging station, one sees only a hardly recognizable periodic flickering of the green LED, but the camera is not charged. This in turn works with the Zens ZESC02B / 00 without any problems. Now I have a charging station (Zens ZESC02B / 00), which can load my two Qi devices without problems, however, is not as well suited for mobile use, because you have to take the proprietary power supply in addition. And the other (here-reviewed) charging station, which I had so specially bought, because these with a USB power adapter (which I travel anyway for other gadgets have this) can be operated. Just stupid that in turn can not cope with the WG-3 :(
