PowerTank Lithium


The new PowerTank Lithium keeps the charge going for the astronomer on the go. The Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries.

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 & 7 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

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-ion designs and will not be a fire danger if accidentally punctured. This, combined with it’s rugged design, make it the perfect outdoor power supply.

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.
