Description

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.
