• Celestron PowerTank Lithium

Celestron PowerTank Lithium


  • 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.
