DIY mobile multi-charger

Mark and Juliette McLean bicycled their way from Liverpool to Australia. The trip took almost 2 1/2 years to complete and they traveled over 24,000 km. During the trip Mark charged his laptop and batteries via his bicycle. It is a great solution for his mobile power needs.

To keep the lights on and the camera going I have a multi-purpose battery charger. This contains around 24Wh of energy storage in eleven NiMh AA cells and circuitry to charge my laptop, satellite phone, mobile phone, camera battery and a PP3 for Ju’s Dog Dazer. It can also power a white LED tent light that sheds just about enough light to cook by. A cunning design means that some of the AA cells can be removed from the internal battery stack and exchanged with flat ones from a torch or whatever.

Make you own Multi-Charger

  1. Wow…if I’m biking 24,000km, the *last* thing I want to do is sap power from my bike to charge batteries.

    Even worse is charging batteries I use to charge other batteries, losing a lot of energy through efficiency.

    Good point. Maybe solar panels, but that would still add weight and not generate as much power? Then again, if you can bike that far, maybe a little resistance is nothing to worry about?
