One of the most annoying things that can happen when you're out and about is to run out of phone battery, and there's very rarely a plug socket around you can hook your charger up to.
It is these times that this little gadget was created for. It might look like a pen, but actually, open it up, pop one AA battery in and it becomes a portable charger that can charge your phone for up to 100 minutes - no mains power required.
That will give you around 20 hours of standby time or two hours of talk time, depending on your handset.
It comes with five different adapters for various mobile phones, such as Nokia, Samsung and Sony Ericsson. And the finishing touch? Put the pen back together, and it actually works as a pen. Marvellous - how very James Bond.
