WE were going on safari and didn't quite know what to expect as far as available electricity. While the rest of the area was dark, we always had power. Even in the Land Rover, I was recharging everyones equipment. No need for converters that didn't work, I just used my SolarRoll and the Brunton Solo.
Children in the Mara and other places in the world travel great distances to get to school, using the Brunton and a solar panel would allow them to attend classes online. It's safer and more fun too.
Back home, we work with horses and people. It's easier to show someone what they are doing rather than explain it. That's when the computer's 5 hour batter is only giving 15 minutes of power. Now that we are back I shall use the Brunton with my computer.
