[From Frederic] Callpod has a very attractive product called ChargePod which can be used to power as far as 6 devices lik PDAs, cell phones, bluetooth headsets. Instead of using 6 wallplugs you use just one. Each device can receive 500mA as if it was plugged in an USB port. You should buy specific adapters to connect the devices to the ChargePod. The ChargePod costs 49,95$ and each adapter 9,95$.
