I've never had a problem with original Apple charging cables for any of my devices, before or after they started lightning connections. I've had great luck with the Amazon branded USB cords, too, which I often get in 6'. This is using them in my van and outdoor with my trailer in all sorts of weather and terrain constantly.
Like any cord, take them out by the end connection, not just the cord, and roll 'em up, not stuff into your bag as a tangle. My grandkid goes through the same USB cables regularly, but from abuse.
I will tell ya to be careful of third party charging cubes and USB ports or regularly using even Apple cubes meant for other devices. Had an iPhone 5s eventually fail due to swollen battery from getting too hot too many times. Was regularly charging it in my vehicle. Lost at least a month and half of photos and other data. Apple replaced the whole phone for around $75 once they determined it was the battery. Prior to that it was old enough they said I'd pretty much have to pay full older-model price.
BUT, the point of my long-windedness is that they said the battery was overheating too often because of charging in a vehicle and other places with improper charging devices that pump out too many amp, often more than twice as much as the iPhone should handle on a regular basis. Here's this interesting screen cap I made when my phone died:
A lot of dual port USB charging devices, like the cupholder deals that also have a 12v outlet, have one port that is 1A and the other 2.1A. I have one that is labeled that way. It's easy to want to use the 2.1 for everything, but over the long term, at least according to many experts, you're not doing your phone any favors.
Moral of the story? Get good cables, but make sure you're using the right cubes and ports to plug them in to, especially if you're planning on keeping your device longer than the upgrade period.
