The charger I showed was the Solio Classic. I bought mine for $99 at Batteries Plus. Based on my research, the real advanttage of it is the lithium battery, which allows you to charge the battery and selectively charge your devices--even without a light source.
The tip selection that came with it works well with a variety of older cell phones, walkie-talkies, etc. Cell phones are now moving toward a universal charger tip that is not included with the Solio. However, the USB output cable for the Solio works with the USB charger cable of my new Blackberry and my wife's Droid, so it's still a viable solution.
I hope this helps.
Stay safe,
Mike
