8．Love camping？Love your iPhone？I have got something to show you．
We have developed a great invention called CampStove（野營爐）．It can charge your phone while you cook．The CampStove has two parts：a furnace that burns sticks and wood，plus a generator（發(fā)電機(jī)） with a fan and a USB port．The CampStove doesn't use gas to light your fires．It only uses the sticks you put into it．The excess（額外的，附加的） energy from the fire's heat can be used to charge small electronics，like an iPhone or LED lights．For users with an iPhone 4S，20minutes of charging through the BioLite（紅外線放散器） equals 60minutes of talktime on your phone （ though，depending on the strength of your fire，charging time can vary）．
Users in the U．S．thought the CampStove was really effective during Hurricane Sandy（颶風(fēng)桑迪） when over six million people lost electricity．Some people were able to carry on cooking and make electronics charged by using the CampStove．The CampStove has become such a success．
We have spent years developing the technology so that outdoor travelers will never have to carry fuel（燃料） again．It is exciting to finally bring this product to market and we have been very glad about the positive（積極的） responses from our users．
The CampStove is a convenient and green choice．It can bring clean and safe energy access（進(jìn)入） to families across the world．It is a great way to mix nature and technology．For more information，you can contact us by calling at 567-987873．
