If you twist the bare wires with some pliers you don't need no wire nuts. Just put a little electrical tape on it when yur done. Or even a dab of masking tape will do.
Otherwise for amateur use I put Anderson Power Poles on everything because I have dozens of power sources and dozens of radios and they make life sooo much easier. Its really nice being able to take any radio or amplifier or charger or whatever and plug it into the car, house, go box, portable battery power, RV, whatever. And if all your friends use Power Poles then everyone is compatible.
However I would never use Anderson Power Poles in a professional environment like public service vehicles, etc, since a snagged power cable can become a single source of radio failure when lives depend on it. Especially when the user is not a ham or radio person tuned into quick troubleshooting when the radio goes dead.
You can get ok crimpers for Anderson Power Poles for $39 and a bag of 25 pairs of red/black 30A Power Poles with roll pins is about $25. I use a lot of Power Pole distribution blocks with 3 to 8 outputs and also have a big MFJ thing with a volt meter and various fused Power Pole outputs that cost more than its worth but I've used it a lot over the last 20yrs.
