1【长难句】

　　It can be plugged into a hand-held device (such as a mobile phone, music player or portable games console) to power or recharge it, and has sufficient capacity to provide around 30 hours of talk-time on a mobile phone, or 60~80 hours of playback time for an iPod music player.

      2【结构分析】

      去掉括号内的举例补充说明，以and为切入点，得到It can be plugged into a hand held device to power or recharge it, and has sufficient capacity to provide…, and并列了两个谓语，前一谓语使用了被动语态can be plugged，后一谓语是has，后面的宾语补足语to provide后的宾语由or并列，分别为around 30 hours of talk-time on a mobile phone和60~80 hours of playback time for an iPod music player。

      3【词汇】

      plug…into… 将…插入…

      device 设备；装置

      portable 便携式，可搬动的---->portable computer笔记本电脑

      power v.提供能源

      have sufficient capacity to do sth. 有足够的能力做…

      4【参考译文】
