During a trip on STS Fryderyk Chopin I used it in series with another regulator - a 230V laptop charger and the reception was still awesome. I have tried a 1/4 wavelength helical VHF antenna and a 1/4 "stripped cable" type improvised antenna, both on a 10 m long cable, even the second got signal from several miles. I will conclude the experiment in a video one day.
You have mentioned UPS HATs in this thread, I am testing powerbank + PIJuice, the GPS reception is neat, did not have possibility to see AIS, so far. I have a video about that setup:

As a rule, the utilization of the AIS recipient is profoundly vitality serious. Also, the new Rpi have more power and require a more serious vitality source.
Regularly, results of Chinese birthplace are not of adequate quality to satisfy this need, I have seen with my own eyes.
Your issue might be in the 12 volts to 5-volt converter - in all probability - or in the link that sends the current to the Rpi.
Most Chinese connectors transport all things considered 2.1 amps and that is insufficient. You can utilize a second 12vlt to 5-volt connector associated with the GPIO pins, it worked for me, or buy one of the qc 3.0 connectors that generally conveys more force.
