Wi-Fi充電器隔空取電
Wi-Fi充電器隔空取電
】Wi-Fi流動上網已不是新鮮事,問題倒是上網多了,手機和電腦的電池消耗就更快。日本一間公司開發了一款可把無影無色的Wi-Fi網絡訊號,轉化成電能的隨身充電器,只要用家身處Wi-Fi網絡覆蓋範圍,充電器便可以源源不絕地向Wi-Fi無線網絡攞電。
這款名為AirnergyWi-Fi網絡充電器,是日本RCA的新產品,將會在今年秋季推出,大小如一部手機,當用家把它帶在身邊,就會自動尋找附近的Wi-Fi訊號,把訊號吸收轉成電能儲在機身的蓄電池內。當用家需要為手機充電時,只需把充電器上的迷你USB插上手機就可以。
除了有儲電式的充電器外,該公司亦開發了一款可從Wi-Fi網絡自動充電的手機電池,有了它以後只要身處Wi-Fi網絡範圍,便不怕因忘記為手機充電,而有話沒法講的尷尬情況。
Move over solar chargers. Step aside kinetic chargers. If RCA are to be believed, there’s a new way to scavenge power from your environment using an energy source that’s all around us: WiFi. If you are reading this article, the chances are very good that you are in range of at least one wireless network. RCA says its Airnergy Charger scavenges stray WiFi signals and converts them to DC battery power that you can use to charge your cell phone, music player, or other electronic devices.
RCA calls the Airnergy a “WiFi hotspot energy harvester”. The device is about the size of a cell phone, with a Micro USB connector hanging off it. Inside is an antenna to receive 2.4GHz (802.11) WiFi signals, and a converter that turns the WiFi energy into DC power which is then stored in the on-board battery. You can keep the Airnergy in your briefcase or your pocket and whenever it is within range of WiFi, it charges itself. Simply connect it to your device to charge its battery. And, unlike solar chargers, the Airnergy works at night.
At the CES 2010 show, RCA claims to have demonstrated the Airnergy charging a BlackBerry from about one-third to fully-charged in about 90 minutes. Naturally, the strength of the WiFi signal will affect how quickly the Airnergy can charge a device.
So is the Airnergy ready for prime time? We’ll definitely be keeping an eye on this technology, but RCA says they are already working on a new version that will be small enough to fit inside an OEM cell phone battery. With the Airnergy harvesting battery pack, you could recharge your phone or other device simply by leaving it range of a WiFi hotspot.
RCA is aiming to bring the Airnergy Charger to market in the third quarter of 2010, with an expected price of US$40.
