On TTX, the receiver tuner is cleared at 18V output and no more than 400mA. In the theory, conversion in 5V 1,4A will be. However, this is all the theory and you can simply turn the receiver tuner with such converters, and there will be no interference in the signal from the converter.
Regarding power from PowerBank. I took myself such on 6000mA. The device works with him half. Those. Initially, setting a certain frequency of one polarization, everything works, the signal is pulled. But during the switching of polarization (inclusion of another transponder with another polarization) the device is lost, the Bluetooth connection disappears. With the connection to the 220V network through the memory 5V 1a, this does not occur. Everything is pulled and switches without loss of communication and efficiency.
It came to the conclusion that there is not enough powerful power to switch from 13V in 18V and decided to make his PB. To do this, use 2 batteries of 5000mA Lipo, each of them ordered a power controller with Ali and the charger itself is:
Thus, I will have to receive 5V 2a at the output of stable.
By the way, about GTMedia V8 Finder BT03. There on the device itself even written power consumption 5V 2A. With such output parameters, it is rather difficult to find the battery, especially from cheap. Mostly they are all up to 1a.https://www.youtube.com/watch?v=emfr96pbtvu.Post has been editedEjSamoGon - 28.11.19, 11:44
