Just like the Radio lamp, the EcoZoom Multi-light eliminates kerosene costs for families living without access to regular electricity. With the Multi-light, families can use the three detachable bulbs in separate rooms, or even outside! The user can charge their phone at home, or on the go with the solar charged portable power bank. This is a tremendous help as many people have mobile phones, but no access to electricity. The Multi-Light t is durable and offers up to 30 hours of lighting.
