Top 5 Positive Customer Reviews for الطاقة التبديل usb
When I started to test, device became hot, like a satan tortures all the politician inside! With corresponding noise instead of sound. The seller requested video for proving, and when i assembled scheme once again - problem has gone. Mystic. Or i soldered inaccurete first time. At normal operational mode device is cold. But looking via oscilloscope is NOT recomended - it is class D (dermoven'ko) amp. Quality of sound is good enouth for "plastic" loudspeaker. And low power consumption is ideal for portative technic. Polarity on PCB seems to be wrong labeled, in datasheet is opposite.
product arrived safely and seems fine - haven't used it as yet. The illustration is accurate but slightly deceptive because it does not appear to have separate reset switch as advertised but does have the reset plug for motherboard. What looked like a reset switch on top of the pic is actually solid moulding around the headphone and mic sockets. the power switch is the only switch as such that I could find. The small square in centre of power switch is not a separate switch either and in unit received it is locked with two small metal strips that aren't shown in the above pic. I suspect the power and reset switches are one and the same but haven't tried it as yet to conform is this is in fact the case.
Very fast shipment, tested this product with a 12V battery and it works fine. Quality seems good, even delivered with 15A fuses in every fuseholder. The cables are done properly, i cut the cables for USB port, voltmeter en cigarette lighter and connected them to the switch outlets.
