The PowerTank Lithium Pro is for the true power user! This higher capacity unit is the latest version of our bestselling powertank lithium>. PowerTank Lithium Pro offers twice the battery capacity of the original, making it ideal for more demanding applications.
PowerTank Lithium Pro features the right ports and connections to accommodate a variety of devices. You’ll find a 12V DC 5A telescope power port (Celestron cable included), a 12V DC 10A car battery adapter port, and two 5V DC USB ports - one 2.1 A and one that supports rapid charging.
The power pack’s extremely portable form factor means it can go anywhere from a remote dark sky location for astroimaging to a weekend of camping. When it’s powering your telescope, use the included 2” straps to secure the unit to your tripod leg where it is out of the way.
One side of the unit features a strip of LED lighting in both bright white and red. This turns the unit into a convenient safety light during star parties or a work lamp to clean up your observing area when the night is done. You can even use it as a bright emergency light during a power failure and illuminate an entire room of your home.
PowerTank Lithium Pro can also travel with you on your next vacation. At 158.72 Wh, it meets current FAA regulations (160Wh) from transportation in your carry-on baggage. Please check in advance with your airline to verify they do not have stricter policies.
Advantages of Celestron’s LiFePO4 Battery
Powered by Celestron's Lithium-Iron Phosphate (lifepo4) battery, PowerTank Lithium Pro is smaller, lighter, and safer than sealed lead acid batteries. The technology is also more environmentally-friendly since it does not use toxic heavy metals.
PowerTank Lithium Pro’s LiFePO4 chemistry holds up to 2000 charge cycles and has an un-recharged shelf life up to 10 years. That means you won’t have to remember to recharge your battery every few months like with a sealed lead acid battery. Its large, 17-hour capacity and lack of maintenance make PowerTank Lithium Pro the ideal choice for an emergency kit. Store one in your home, your garage, and even your office.
