Sony Japan\u00a0just took the wraps off\u00a0a new \u201cCP-A2LAKS\u201d\u00a0portable charging gadget\u00a0that\u00a0lets you to recharge your mobile devices without an electrical power source, by cranking a wheel. The charger is made of three components: a \u201cUSB output section\u201d\u00a0that contains a 4,000 mAh battery; a "hand-cranked generator input" section; and an AC charging unit.\n\tThe latter two components are interchangeable,\u00a0and the primary \u201cUSB output section\u201d has two USB ports\u00a0that can be used to\u00a0power\u00a0up a\u00a0variety of mobile devices and smartphones. The AC charging part lets you plug the unit into a power source to charge\u00a0its battery in the traditional way.\n\tUnfortunately, the CP-A2LAKS "hand-cranked portable charger" probably won\u2019t be able to\u00a0power up\u00a0your iPad, since it has a maximum output of only 1.5A.\u00a0Sony says it should take about 5 hours to fully\u00a0charge the internal battery\u00a0using the AC charging unit.\n\tRotating the\u00a0hand-crank mechanism for about\u00a0three minutes\u00a0at 120 revolutions per minute yields enough power\u00a0to make a one-minute smartphone call. And five minutes of cranking gets you about a minute of Web browsing, according to Sony. The hand-cranked input section is relatively lightweight at just\u00a0126 grams (4.4 ounces).\n\tThe hand-crank can be used as emergency power backup in locales such as earthquake-prone Japan,\u00a0and it's also ideal for extended hikes or other outdoor activities.\n\tThe CP-A2LAKS hand-cranked portable charger will set you back\u00a0about $100 (\u00a58,000), and it's expected to\u00a0be released\u00a0on June 20. However, it's unclear whether or not the product will\u00a0be sold outside of\u00a0Japan.
