A while ago I found out that it was possible to charge my N810 via USB connected to a regular PC. This can be very convenient if you don't have a socket available for a charger.
The Nokia N810 has the ability to be a USB host. It can provide a little bit of power via it's micro-USB port. As you can see in the picture, the device notices that the charger is connected.
Tools needed for this trick:
- Nokia USB charger
- USB F-F adapter
- Standard micro-USB cable
Urho Konttori's usbcontrol
By now you should probably already know that this about the same as Perpetual motion, a great idea, but impossible (Without rewriting the laws of physics).
But still, it is good fun to see the charging notification pop up.
