The only thing this feature-packed field battery doesn't do is toast! It's a portable 17 amp-hour, DC power supply with two 12V "cigarette lighter" output ports (10 amps max.), plus 3V, 6V, and 9V male pin jack outputs. It's fully rechargeable, and 110V AC and 12V DC charging adapters are included. An indicator light tells you when the battery needs recharging.

The Dynamo Pro 17 has other features that make it indispensable not only for observing sessions but also around the house and in vehicles for emergency situations.

• Removable red flashlight with 11' cable and magnetic mount
• Bright, 55-watt white halogen spotlight
• AM/FM radio for entertainment or emergency broadcasts
• Booster cables to jump-start a weak car battery (250 cranking amps, 5 seconds)
• Circuit breaker fuse for safe operation

How did we ever manage without the Dynamo Pro 17? It'll keep you powered up as well as prepared for any emergency, at home or on the road. Weighs 19 lbs., 12 oz.

For powering electronic telescope drives, the Dynamo Pro is recommended only for those requiring 12 volts DC. Such mounts include the Orion Atlas, Losmandy G-11, Celestron NexStar GPS and CGE, Meade LX series and LXD-55.
