Creative Mouse Wireless Notebook Optical review
Reviews To set up the Creative Mouse, simply pop in two included AAA batteries and plug the receiver into your notebook's USB port. Otherwise, its performance is average, and in tests with fresh batteries, the mouse worked up to 2 metres away from the...

Inside a notebook battery pack review
Reviews Lithium ion batteries aren't so much popular in modern mobile IT as essential. The most impressive part of lithium ion batteries isn't that they can go catastrophically wrong, but that they only do so rarely -- one or two times per million units...

Xircom SpringPort Modem 56 GlobalACCESS review
Reviews Unlike many Springboard modules, which sit flush with the Visor, the SpringPort Modem 56 is bulky, due in large part to the three extra AAA batteries the modem requires to operate. Setting up the modem is easy: just drop in the batteries, plug the...

SiPix Pocket Printer A6 review
Reviews Running on four AA batteries or a mains adapter, it has a serial interface and an infrared port. The batteries don't last very long: the printer is rated at 15 watts, although it turns itself off after three minutes to save power.

HP Jornada 928 WDA review
Reviews Second, the Jornada 928 WDA has two batteries. Between them, these batteries deliver a claimed 12 hours handheld usage, three hours talktime and 150 hours standby -- more than a match for other handheld/phone convergence devices.

Microsoft Wireless Optical Desktop for Bluetooth review
Reviews Four AA-size alkaline batteries are supplied -- the keyboard and optical mouse both require two batteries to power their embedded Bluetooth transceiver chips. Despite the rather ‘chunky’ shape of the mouse and its noticeable weight when the...

Motion Computing J3400 review
Reviews The J3400 accommodates two 30Wh batteries, weighing 1.63kg with one fitted and 1.81kg with both in place. It's not exactly lightweight, especially with both batteries, but it feels reasonably comfortable when held in the crook of an arm, and there...

Psion NetBook Pro review
Reviews AAA batteries are much more widely available than the coin-type cells used by many handhelds -- and previous incarnations of this device. Backup battery power is provided by twin AAA batteries, which sit in a slot that becomes accessible under the...

Soundbug review
Reviews The batteries last around four hours at medium volume, which for three alkaline AAA cells is a high running cost. Even if you do manage to get the Soundbug to do something that would be hard to replicate any other way ( putting it under the bath so...
