Continuing with the theme of essential travel gear, I thought this little gadget would be a great idea for most of the travelers. These days almost no one goes anywhere without a cell phone or smartphone. Most of these devices do not have that great of a battery live especially the smartphones. It is rare for the battery to last more than 5 hours at best. If the phone is also used for navigation or game playing the battery live might be much much less. And that is where travel gadgets such as Dynamo Hand-Crank USB Cell Phone Emergency Charger come in. It is small 2.4 x 1.2 x 1.8 inches and its power source is readibly accessible since it is your hands. It allows you to generate sufficient power to recharge a cell phone battery via repeated turns of the handle connected to an internal alternator. It’s designed to work with most cell phones with a USB port. There is also electronic alternatives such as this Emergency Cell Phone Charger, that come with several adapters for various phone types. Though an USB-port would work for most of today's phone and especially smartphones.
Considering these cost under $30 bucks, you could toss one of these in a car and/or a backpack while traveling all over the country
