Russian Hydrogen Powered Charger
The Russians aren't only good at gymnastics and synchronized swimming, they're also pretty adept when it comes to developing green technology. Take this hydrogen powered charger for instance - it weighs a mere 180 grams and offers up to 5 charge cycles, juicing up a totally run-down phone within 10 minutes to a quarter of an hour - that's extremely fast, compared to current adapters that take hours to complete their task. Sounds like the perfect gadget to keep you company on your travels as it doesn't bog you down with additional weight and space, not to mention being a whole lot greener for our environment.
