moitessier hat - AIS reception varies by power source
#2
In general, the use of the AIS receiver is highly energy intensive. In addition, the new Rpi have more power and require a more intense energy source.

Often, products of Chinese origin are not of sufficient quality to meet this demand, I have seen for myself.

Your fault may be in the 12 volt to 5 volt converter -most likely - or in the cable that sends the current to the Rpi.

Most Chinese adapters ship at most 2.1 amps and that's not enough. You can use a second 12vlt to 5 volt adapter connected to the GPIO pins, it worked for me, or purchase one of the qc 3.0 adapters that usually delivers more power.

There are also pad-type adapters that deliver 3 up to 5 amps or even 10 depending on price.
