Celestron Portable power pack for your computerised telescope
Uses Lithium Iron Phosphate (LiFePO4) chemistry
Smaller, lighter, safer, and easier to maintain than lithium-ion and sealed lead acid designs
Up to 2000 charge cycles – four times more than lithium-ion and seven times more than sealed lead-acid designs
Un-recharged shelf life of up to 10 years – 3 times better than lithium-ion and 10 times better than sealed lead-acid designs
Environmentally friendly – Does not use toxic heavy metals
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 Celestron PowerTank Lithium is a portable power-pack that keeps the charge going for the astronomer on the go. The PowerTank weighs just over 1kg and is only 7.5″ long by 3″ in diameter. It has a rubberised protective cap that, when removed, reveals two 5VDC USB charging ports and charge indicator lights. It also features a Red and White LED light source, with two brightness settings for each colour. It comes supplied with AC charger unit with various plug adaptors and a velcro strap so the PowerTank can be attached to your telescope mount’s tripod.
The Lithium Phosphate (LiFePO4) battery chemistry of this power supply has significant advantages over other battery types: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 degrades at a much slower pace than other chemistries.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.All the above, combined with it’s rugged design, make it the perfect outdoor power supply.
