I'm surprised by the your turn around opinion on these.
I still use them both in the shack and mobile with little to no failures any more. I have multiple power pole rig runners and it makes the most convenient way to run power to all my 12v devices. I also use the larger 350 amp versions for high current connections.
One issue I had is with small gauge wires would easily break off if I handled them a lot. This is due to the fact that the smaller the wire, the weaker the crimp is whereas with 4 gauge wire I use for my mobile HF amp is virtually unbreakable.
The 45 and 30 amp powerpole connectors hold up just fine using wire gauges from 10 to 14 but on the 15 amp connectors, I found if I strip the 18 gauge or thinner wires longer than normal and fold the wire down on top of each other it gives more surface area for the crimp to bite down on.
Other than that as long that I plug and unplug the connectors by grabbing the connectors and also making sure there is no tension and some slack on the wires when making connections, I don't have any failures.
I agree to using only true Anderson Power poles and the right crimper. I haven't seen any knockoffs but I wouldn't doubt they are out there.
What issues have you had that made you change your mind on these?
