I tried the N900 USB cable on my Tekkeon USB phone mobile charger and the N900 did not indicate that it was charging. But using the Tekkeon supplied universal cable and Nokia micro USB adapter, the N900 started charging right away. So having the the right adapter is important. Just having a source of 5 volts isn't enough. I bet the pictured adapter would have worked with an adapter with a Nokia pin out.
