Then an instruction manual / data sheet is still in English and Chinese.
Important information therefrom:
- People with pacemakers should please contact their doctor before use and generally keep the pad at least 50 cm away from the pacemaker.
(And so on credit cards, EC) put a map on the pad -
- The pad reaches an efficiency of greater than or equal to 70%
- When the battery is full, the pad goes into standby and not charging unnecessary to further
- Red LED on: Pad is connected to power and standby
- Blue LED on: device on the pad is loaded
Yes, it can be heard softly whistling, but only when I hold the ear directly to the pad. In normal operation, I hear nothing. A beep when connecting or disconnecting there is not - only the phone itself.
I did a test and the cell phone 30 minutes to Qi pad and 30 minutes on the cable (qi out, cell phone off - ie the same source) loaded. Then I have the battery history viewed (under Settings> Battery and the App Battery Widget Reborn). The app evaluates pretty accurate and you can zoom into the charging curve. There are the Qi charging some minimal fluctuations recognizable. Overall, the line runs but on both recharges completely straight. No difference can be detected in the Android-battery indicator. To test it exactly but you would have to turn off the phone, then measure the exact charging time and compare. For me, it is, however, interesting. Subjectively, I say, the phone loads just as fast on the Qi as the cord.
For about 9 euros there is in my opinion a super Qi charger that probably comes from the same band as the two or three times as expensive pads that you can buy here.
