PowerTank Lithium Power Pack
Overview:
Keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices as active as you are with PowerTank Lithium—the ideal outdoor portable-charging solution for your electronic gear.
The PowerTank Lithium keeps the charge going for the astronomer on the go. The Lithium-Iron Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries.
The LiFePO4 has an un-recharged shelf life of 10 years compared to 3 years for the Lithium Iron and 6-9 months for a Sealed Lead-Acid battery. The battery performance of the PowerTank Lithium phosphate degrades at a much slower pace than other chemistries.
Features:
• The LiFePO4 can be charged and discharged 2000 times compared to only 500 for a Lithium Iron battery and 300 for sealed lead-acid designs.
• The batteries will last as long as the telescope you use it with!
• The LiFePO4 uses phosphates instead of environmentally hazardous elements like cobalt or lead commonly found in other rechargeable batteries.
• Can withstand higher temperatures than lithium-iron designs and will not be a fire danger if accidentally punctured.
• This combined with its rugged design make it the perfect outdoor power supply.
Included Items:
• Battery pack
• AC mains charger
• Power cord for Celestron telescopes
• Strap for attaching to tripod
• Strap for hanging
