This handy 4 in 1 cable allows me to charge every device I travel with.
This cable will charge my iPad 2, iPhone 6, GoPro and a wifi hotspot in the car today. I like that it reduces the number of cables jammed in my glove box or sitting on the floor, and that I can keep them all plugged in at once.
In the future, it may save me the joy of wandering around a foreign city looking for a USB cable, I've done this more than once.
