eBooks enable people on the move to download and store up to 500 books to read anywhere, anytime. Typically powered with 4 AA batteries, the latest generation of eBook readers uses new display and electronic ink technology in a compact, lightweight device about the size of a paperback novel. Wireless Internet connectivity give these appliances […]


A variety of toys such as model airplanes and “instant” charge cars from Mattel® need electric power to operate. The power options have tended to be physically heavy products with low energy density that are unnecessarily bulky. Manufacturers now want light-weight toys using power components that are smaller and less expensive. The thin, small size […]

Converged Handhelds

Converged or “smart” handhelds integrate the wireless, voice and data capabilities of PDAs and mobile phones into a single device. But other convergent devices are already appearing that merge mobile phone-cameras with MP3 players and PDAs, and patient alert tools that bring together GPS trackers with personal or emergency alarms. When combined in one package, […]

Digital Music Players

Digital music players record and play music compressed into the MP3 format and can carry 1,000 or more songs in memory, giving large music libraries true portability. As with many other mobile appliances, these thin, palm-sized devices are pushing the limits of existing battery technology with their increasing power demands and upcoming use of wireless […]

Notebook PCs

Short battery life is still one of the limitations of notebook PCs. A laptop is only functional for as long as it can store enough energy to power it. To enhance and prolong the power management system, a supercapacitor can be used to reduce excessive power load and thus extend the battery’s run time. CAP-XX […]

Digital Still Cameras (DSCs)

  Digital still cameras (DSCs) require a substantial amount of energy delivered at very high power for the switch-on, zoom, autofocus, and image capture stages of operation. Additonally, new technologies such as white LED feature lower power consumption but have high peak-power needs. These demands place an extreme load on batteries, quickly lowering the voltage, […]
