I'm with crxess, it was a short. USB cables matter too, how the micro USB end is constructed can make a big difference. If the connector is too long it can allow a lot of torque on the connector...if the plastic end doesn't sit flush with the device when it's inserted it can cause the same problem. If the connector is too short you run into a similar problem, that's more likely to munge things up inside the connector.
And in the case of the Mini, if you look at the supplied cable, it's of the long variety to suit the recessed USB port, and sits flush and straight when inserted, not a lot of room for wiggle or torquing. But if you look at a cable supplied by Samsung, LG, HTC or Motorola (I've got all three), they're generally the shorter variety (the most common type actually), designed to fit in a more flush mounted micro USB port, and sit at about a 10 degree angle when inserted into the Mini, which ain't ideal. In the case of both the Samsung and LG cables, the outside of the connector itself is more narrow as well, providing less support for side-to-side flex.
TL;DR: Take a look at the cables you want to use with the Mini, see how much they vary from the cable Cloupor supplies. If they're not a real close match in size and length, don't use 'em, or if you do, don't use them while vaping or moving the device around a lot, to minimize stress on the connector.
If you just use any old micro USB cable you have laying around, you'll eventually run into trouble. At the very least, you're looking at damaging the connector so it won't charge, at the worst you're looking at something more...dramatic.
