Road Warrior Tip: Leave the charger at home with USB batteries
I've been doing a lot more travel lately for my new job then I'd like, and I'm getting pretty good at slimming down what I lug around in my laptop case. Every electronic gadget I bring adds a few ounces to my laptop case, and they each add up to a sore shoulder while rushing to catch connecting flights.
I do have a couple gadgets though that make it on the short list of "must haves", and a couple of them require AA batteries - a laser pointer/remote slide controller device that lets me advance to the next Powerpoint slide even if I'm on the opposite side of the room from my laptop, and a wireless optical mouse (the fewer the wires, the better).
I'd hate to be in front of a group of paying customers, only to discover that my batteries were dead, but I also don't want to carry around a battery charger or have extra batteries floating around my laptop case.
Enter the perfect solution: USB rechargeable batteries.
