Monoprice Atlas Flex USB-C Cable ($18)

There’s no reason a good cable has to cost a lot of money, and if you have some extra cash lying around, it might be a good idea to replace any old or aging cables. Some old USB cables might not be able to fully support the faster charging speeds of more modern power adapters. When you’re gearing up your bag, you can throw an extra USB cable like the Atlas from Monoprice in there as a backup or to help out a friend in need. At this point, I’ve lost count of how many times I’ve lent out a spare USB-C cable to someone whose phone is about to die, which makes a spare cable one of the most useful things I carry.
