San Francisco start-up Fenix International has developed the ReadySet, a lead-acid based battery, housed in a safe, leak-resistant plastic casing that has plug-in adapters on the exterior shell. The battery can power multiple lights and electronics at the same time. To recharge the battery, users can pedal on a stationary bike, use a mini-solar panel that comes with the battery, or use existing nearby electricity. The ReadySet costs $150 before shipping.
