Celestron PowerTank Lithium Iron Phosphate, 86.4 WH

Keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices charged and ready with PowerTank Lithium—the ideal outdoor portable-charging solution. Celestron specially designed this product with the needs of amateur astronomers in mind; it’s packed with useful features. First, you’ll find a 12V connection for your Celestron telescope—no cigarette lighter port needed. Once your telescope is connected, attach the battery securely to one of the tripod legs with the included Velcro straps so it is safely out of the way. Two USB ports, one quick-charge and one regular, keep your other devices charged, and can be used simultaneously with the telescope charger. When your eyes are dark adapted, use the red LED flashlight to navigate your observing site without sacrificing your night vision. When the session is over, turn on the bright white LED flashlight to illuminate your site and ensure no lens caps or eyepieces are left behind in the dark. When you’re not observing, keep this battery charged and at the ready for unexpected emergencies. PowerTank Lithium’s unique Lithium-Iron Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries. It will last you many times longer than sealed lead acid or lithium cobalt batteries thanks to its un-recharged shelf life of 10 years and 2000 charge cycle lifespan. It’s also better for the environment, free of toxic heavy metals like cobalt and lead. But most importantly, LiFePO4 can withstand higher temperatures than standard lithium cobalt batteries and will not be a fire danger if accidentally punctured. All this combined with its rugged design make PowerTank Lithium the perfect outdoor power supply.
