Harness The Power of The Sun
Airlines are starting to offer USB charging for their passengers but not all do. One way to get some extra juice for your devices while on a long flight is the Port Solar Charger. Just stick it to the plane window when you board the flight and let it soak up all that sun power.
The Port Solar Charger has a built-in 1000 mAh rechargeable battery that can be charged using solar power or plugging it into a USB charger. It works with any USB powered devices. You can leave it on a flat surface with the solar panels facing upwards or for more efficient charging, stick it on the window. It has a sticky ring around the panels.
