Spring has sprung, which means we’ve finally escaped one of the most extreme winters in recent memory. Weather.com says we should prepare for more large-scale climate events that will cripple power grids, resulting in prolonged power outages. Part of being prepared means having a back-up power supply, and companies like Goal Zero are here to help. Goal Zero’s smallest kit, The Guide, can power or charge your smartphone or tablet, and can be re-charged via USB or by plugging it into a solar panel, like the Nomad 7. GoalZero’s Escape 150 can power just about anything with a standard A/C power cord, like your laptop or camera, and can be re-charged through A/C or through the Escape 30 Solar Panel Briefcase. For prolonged blackouts, something like Goal Zero’s Extreme 350i Power Kit do the trick. I recently used it to power my MacBook Air and a satellite phone, as well as a small refrigerator. I can tell you from personal experience: when you need a solar-chargeable power supply, you’ll be really happy you have one.
