Very nice led tube with warm led light color. It is easy to setup and has enough power to light correcly my small counter. Be aware that the light comes without any power supply. I has several so it was ok in my case. I measured ~450mA under 12V, (5W input power).

Q: if only used with aux out (active speaker ) it needs to be powered?

zapytał alessandromagnaghi na 2020-12-01 01:00:35

ThomQc Yes, it needs to be powered to convert digital sound to analog (both active and passive speakers are analog). Aux out level can also be adjusted by the master volume knob. In my experience, you have to turn it to max to have a decent line level (for active speakers).

I did not have time to fully test the scope but seems quite good and very easy to use. I just measured the calibration probe signal and noticed a small discrepancy between both channels PP voltage (~0.1v)... Not sure if I can calibrate it. But even is it is not a high precision tool, it seems a very promising and practical tool.

I bought two units for moisture measurement in my house. First thing I have done is to put both hygrometer in the same place (one besides the other) to evaluate roughly their relative accuracy. They gave me a 5% difference wich is within the indicated specifications. Sincerely, for the price, I thought it would be worse. So I am quite happy with this product. The display is clear especially if you are interested in the hygrometer measurement since the number is bigger than the temperature. Other less important values (min, max) are smaller so it is easy to read and find information. The color indication for hygrometry is a gadget for me but it could be usefull as a reminder for moisture level confort zone . Overall, for the price I would recommend this product.

This adapter works exactly as expected. I use it with a raspberry pi to display on a old VGA display. The compact design is a positive point for me.

Just installed so I cannot comment on the charging rate and autonomy. The light is bright enough to light a small passage.

The parcel was crushed in the shipping I'm wondering if it was damaged. There is no visible damage but the light behaves weird. I charged it for 2 days but it still only light very dim.
