The Choetech Qi charging station does not just look pretty, they also served their purpose to my complete satisfaction. My Nexus 4 smartphone and my Nexus 7 Tablet can be both wirelessly upload what I feel to be quite comfortable. Instead of the USB connector into the unit to fumble simply place the unit in passing on the rubberized pad - done. A slight warming is this normal; my Nexus 4 but heats up noticeably and measurably more than the Nexus. 7 The existing on both units casings must not be removed, and by the elongated shape can be at least the Nexus 4 hang up so that the charging starts immediately safe. The larger Nexus 7 has to be somewhat more accurately positioned, then everything runs smoothly even with him. The charging time is slightly longer than wired; the Nexus 7 does not send a signal to switch off the pad and will be read as well as in the guidance, continue to be supplied with low power, which does not damage the battery. The Nexus 4 on the other hand brings the charging mat while to switch off, but always before reaching the 100% mark, but what I do not bring back the Qi charging station but the Nexus 4. Overall, however, a favorable, superbly finished Qi charging pad with pleasing and practical design.
