Basically The SynCh is a extendable charger and USB hub, with a USB plug at one end for plugging into a laptop, and a custom power socket and USB socket on the other. Into one of those you can plug a number of adaptors: I have a mini-USB plug for data transfer, a Nokia old-style charger, a Sony PSP charger (for the Zaurus), and an iPod charger. I also have the travel adaptor, which lets me plug the SynCh into UK, EU or US sockets for charging from the mains.

It's pretty cool, and I recommend that anyone who ends up taking seven chargers away with them look at getting one. It's also a lot cheaper than the iGo! My only problem is that the iPod charger won't charge my 3G iPod, but handles 4G and newer fine. Apple must have done something odd...
