I never travel to a new destination without a Lonely Planet guide book. They are full of background information, history, anecdotes and insider tips for the city or country you are visiting.
My GoPro camera captures amazing photo and video, and is incredibly easy to use. The best part is the price - brand new, 1080p HD GoPro cameras start at under $200!
I've found that duffel bags are the easiest type of luggage to carry if you are a power wheelchair user - just sling the shoulder strap over the seatback and roll away on your wheelchair travel adventure!
The Bose QuietComfort series of over-ear headphones is a travel accessory that I won't go anywhere without. The noise on long flights and train rides is canceled out, giving me the opportunity to work or sleep in peace and quiet.
If you're traveling abroad with a power wheelchair or scooter, you'll need to buy a step-up/step-down power transformer, which safely converts the voltage from 220V to 110V, or vice-versa.
Amazon's Kindle has changed the way I read books. The Kindle makes reading so much easier, faster and more accessible. My favorite model is the Paperwhite, but there are many different models and sizes to choose from.
