太阳能钥匙扣电源

新华网9月10日电 科技博客Gizmodo刊发文章，介绍了一种可为移动设备充电的太阳能钥匙扣电源。原文编译如下：

为移动设备准备再多的备用电源都不嫌多，这款太阳能钥匙扣电源不仅小巧便于携带，而且可以利用太阳能源源不断地储备电量。那这样小的太阳能电池板充满电是不是得花上好几个小时呢？它可以配备额外的太阳能板提高储电速度。这款钥匙扣500毫安时的电池只足够给iPhone充电20%，相当于iPhone工作一小时的用电量，但偏弱的供电能力正是便携式电源不得不作出的让步。而且只要这款钥匙扣电源处在光照环境下，就无需担心其充电的问题。

使用一块太阳能板的情况下，这款小巧的钥匙扣电源全部充满电大约需要10个小时，同时使用三块太阳能板的情况下，充电时长可缩短至3个小时，若六块太阳能同时使用，充满电只需要1小时。当然它也可以通过USB充电，这大约需要2小时。现在这款钥匙扣电源在德国的售价是48美元，单块太阳能板的售价为9美元。未来几个月内，这种太阳能钥匙扣电源有望在欧洲其他国家面市，一年内有望在世界各国发售。

Daisy-Chain This Keychain Solar Battery's Panels For Faster Charges

You can never have too many sources of backup power for your mobile devices. And not only is the compact ClicLite easy to carry around, it also charges itself using the sun's continuously free rays. But what's that you say? That tiny solar panel will take hours to recharge its internal battery? Well then it's a good thing you can increase its sunlight-trapping capacity with extra snap-on panels.

The ClicLite's 500-mAh battery isn't terribly capacious. It's only capable of charging an iPhone up to 20 percent of its full capacity. That's enough for about an hour's use, but that's the price you pay for portability. As long as you keep your keys out in the open, however, you never have to worry about charging it.

With a single solar module the ClicLite needs about ten hours to recharge its battery. Add a couple more and you can reduce that to three hours, and with six daisy-chained modules it takes just an hour. It can of course also be charged over USB if you've got two hours to spare, but no sunlight at your disposal. Available in Germany now for $48 plus $9 for each additional solar module, the ClicLite is looking to expand to the rest of Europe in a few months, and then everywhere else the sun shines in a year or so.
