Query: Perfect Travel Razor

Having previously owned battery powered travel razors, I was always disappointed with their power and battery life. After all, what's the point ditching a heavier charger and razor if you have to carry a load of extra batteries and still end up stubbly faced? The Braun 370-BK was a pleasant surprise, however; powerful enough to hack through my hiking stubble and plenty of juice for an extended outing. I also liked the folding design which protects the cutting surfaces and keeps the cleaning brush from getting lost. A great piece of tech at a good price.
