Sony's new consumer electronics devices is another one in filling the mobile power supply niche, competing with products from other companies. The Energy LINK USB has the ability to power up most portable, USB-compatible electronics devices.

The Energy LINK USB portable power supply and adaptor is packaged with two AA rechargeable Cycle Energy batteries, which bridge the gap between regular alkaline batteries and the NiMH rechargeable batteries. It fully charges in about 3 hours.

The new power supply also takes advantage of the USB de facto standard, being compatible with most USB-compatible MP3 players, mobile phones and other USB-powered devices.

The Energy LINK USBportable power supply and adaptor will be available early this summer (in the U.S.) for a suggested retail price of about US$35.
