Sustainable energy has finally gone “emergency” with the Weza portable energy source. This $299 gadget can be charged from an ordinary power supply, but it can also deliver 25-40 watts via the foot pump. The Weza can jump-start a car or boat battery, and the handy input gauge lets you see how much effort you need to add before you can get your vehicle up and running again. No more tow truck assistance needed for those dead batteries, just whip this baby out of your trunk and start pumping.
