I carry a mini USB cable to power a portable USB hard drive when I travel. Additionally I carry a micro USB cable to charge my mobile phones. I use the word carry lightly because I constantly forget a cable and need to run to Best Buy or a Verizon store to buy yet another charger. I have 5 micro USB chargers and still somehow despite keeping one in my travel backpack and one in my briefcase, I can arrive on a trip without a cable.
A fellow road warrior introduced me to these little converter cables the take a mini usb and converts it to micro. I bought a couple and added to my travel bag hoping it will prevent me from buying yet another charger. The brilliant thing about these converter cables is they cost $1.14 from Amazon. Â I bought 3 because the shipping cost is $2.98 and it is not eligible for Amazon Prime shipping.
I rarely get tips form friends the cost $1.
