Here's an interesting widget for touring cyclists. The Brunton Metal 4400 Electronics Charger is ideal for touring or multiday events where you might not guarantee a source of electricity, but want to charge your mobile phone, GPS computer or lights.
It's very compact and not all that heavy at 208g, with a natty carbon fibre-look back plate. It's not something you're going to carry in a jersey pocket, but it'll go in your pannier or saddle bag.
Inside the tough case is a 4400mAh lithium-polymer battery, which I found was plenty to charge my smartphone a couple of times and top up my Garmin Edge 500. An iPhone 5 has a 1,440mAh battery so that gives you some idea of the charge the Brunton stores. They claim it'll charge four smartphones, and my testing showed this to be the case.
A small LCD screen serves as a power level indicator so you know when you're running low. To charge the Brunton from empty takes about four hours from a USB port. Bruton claim the battery can be charged 1000 times.
There are two leads, a micro USB - fine for my Samsung phone - and USB 2.0 lead that can be plugged into any compatible device and also used to charge the Brunton. In the top of the unit is an integrated USB port for plugging any compatible device in, your tablet, phone, MP3 player, lights or GPS. The only change I would make would be to add a mini-USB lead so I could charge my Garmin without needing the correct USB lead with me. It would be perfect then.
The Brunton is a smart and well designed reserve battery that works well, and provides plenty of juice for keeping your gadgets topped up. That's ideal if you're planning to ride over the course of a few days and don't want to let your phone or other device run flat. I've also found it handy for travelling, and given how small it is, I've taken to always stashing it in my bag when travelling, just case I need it.
