רכיב משחק USB ל-DC USB Power Boost Line DC 5V To DC 12V Step UP מודול מתאם USB ממיר כבל 2.1x5.5 מ"מ תקע

The cable is functional, but the meter shows 8.87 volts It will turn out during operation whether this is enough to power the device.

Burned out the first time I connected it! It's not 12v but 9V...

Works show 12v. Later I connect it to some device we'll see

All good, works perfectly, 🇧🇪👍👍👍
