I use the suns energy to tame my beard! I used our Goal Zero Guide 10 solar charger kit to charge by beard trimmer. Then I used it (along with the power of the sun) to trim my beard. It cut so effortlessly and environmentally friendly I felt like I had just saved a bunch of whales from a burning building. It was amazing.

Update May 2nd 2015: We used our solar panel every day for 10 days during our boat trip and it was totally worth the cost. It allowed us to keep our go pro camera fully charged and we took tons of great snorkeling videos. There was quite the line for the inverter on the boat, because of the 14 people trying to keep camera, phone, etc charged. We even used it for some power bartering so we could keep our laptop charged by letting the two people in line use the battery pack and charge directly on the panel. We hooked up phones to the USB charge port and within ~4-5 hours they were 100%.
