While Statusmonger has most of the necessary travel essentials in his laptop bag, I would like to add two more items to his list. I believe a true global road warriors should have these two items because no road warrior can live without power. Having traveled across the globe for the past decade, I still cannot live without these two items. With these two items, you can leave all the AC power cords home. All you need is to take your USB cord and AC power adapter for your laptop!
The two items are:
1) Universal AC wall adapter – Regardless of your AC power plug’s country of origin, this universal AC wall adapter allows your power plug to be connected to any wall outlet in any country. I have used this universal AC adapter in Europe, Asia and Australia. I’ve also lent this universal AC adapter to visitors to the US. The universal AC wall adapter is a cube shape – about 2×4 inches max and very light. The universal AC adapter has two sides. One side that has three different prongs to be plugged into a wall outlet. The other side is a universal wall outlet receiver for your plug power cord. You can purchase the universal AC adapter at Fry’s for less than $20 (or in China). Don’t buy it at Brookstone’s or airport stores because they are opportunists & will rip you off.
2) Car lighter USB charger – Like the universal AC adapter, the car lighter USB charger allows you to charge your electronics wherever you are in the world. Car lighter chargers are standard across the world - probably the only universal power source in the world. This car lighter USB charger turns your car lighter socket into a USB port. All your need to do is plug one end of the charger into any car’s lighter outlet socket. The other end of the car lighter USB charger has a USB female connector which is for the USB cord (just like a computer USB port). When you are on the road or in another country, all you need is a USB cable to plug into the car lighter charger to ensure your mobile phone, iPod, digital camera, etc. are fully charged during your journey. You can leave the extra AC power cords for your Canon camera, Apple iPod, etc. at home. Leverage your PC or rental car for juice!
