The Sanyo MQR06 is a compact charger. With 120 g it is significantly lighter than a BC700 (260 g with power supply unit) and is ideal for travel. The power cord can pull and fold the pins including hidden for US power outlets. By asymmetric position of the connector only outlet is blocked right next to a power strip. At the bottom you will find 4 blue LEDs that light up during charging.
I have read several times about noise during load:
If one ear to the charger, you can hear a "tick-tick - tick - tick" at a distance of 0.5 s, if 4 batteries are inserted. With 2 batteries in the outer wells, the distance to 1 increases s and with only one battery to 2 s. The charge pulses are well-distributed periodically to the assembled charging bays, resulting in an average of said charging currents of 560mA, 1120 mA or 1680 mA ,
After 5 minutes - with two batteries in the outer shafts - then a beep is heard (approximately 1 m distance), but shortly afterwards it was gone again. Presumably, an inductance is not shed properly in the device.
The compact has a serious drawback:
The Ladegarät was significantly warm, top right, it was after 10 min 46 ° C. The batteries were warm: the positive pole 43 ° C and 33 ° C at the negative pole. Quick charging with 2 batteries is not recommended mE!
In another experiment with 4 batteries I blow a stream of air from a PC via the fan Ladegarät lasssen how I do it even when BC700. Over the 4-hour charging time, the battery heated at the positive pole to 30 ° C, the negative pole to 25 ° C, therefore only slightly above room temperature.
Conclusion: the charger is quite useful, but you should always be four battery load with the small charging current of 560 mA at the same time.
