About a year ago, I wrote a blog article reviewing the OQO 01+ UMPC. I rather liked this PC, and indeed still do, though one does need to take into account its limitations. Unfortunately, the same cannot be said of the power supply, which after a few months stopped working.
To clarify, the power supply brick has one output (with a peculiar 5 socket plug, of which more later), and two inputs - one is for mains, the other is for 12V car adapter input. It is the former input that has blown, and this seems to be far from unusual. It occurred to me that I could update my blog while on summer cycling holiday, with the OQO plus the Vodafone 3G stick (well, at least while I was within transmitter range!). However, my workaround power supply required the use of a UK mains > 12V power supply to power the OQO power brick. Tis is far from being portable.
