I have a number of USB chargers, cables and power banks with uUSB connectors that just don't mate properly with any of my Pi's (Too loose) That's why I gave up using them. I have exactly 1 that does fit well, but it is connected to a 1.5A charger (for a tablet) so only usable on an older Pi . I almost gave up on the pi 6 years ago with my first model B because finding "bad" connectors and cables was a lot easier than finding good ones
Since then, I have used pins 2/6 on all my Pi's (15 I think, and my "Other board") with no problems. I know it bypasses a lot of circuitry on the Pi, but I have the ability to measure voltage, count pins,solder and see colored wire. (BTW - if you do this, don't rely on the red/black being the power wires in all USB connectors - I have also encountered a few powered USB supplies that had Red/Green (data) and Black/White (power)!
