The Celestron PowerTank Lithium Pro is the PowerTank for the true power user. This higher capacity unit is the latest version of the bestselling PowerTank Lithium. The Celestron 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. There is 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.

The PowerTank Lithium Pro can also travel with you on your next vacation. At 158.74 Wh, it meets current FAA regulations (160Wh) for transportation in your carry-on baggage. Please check in advance with your airline to verify they do not have stricter policies.

Powered by Celestron's Lithium Iron Phosphate (LiFePO4) battery, the 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.

- Extra-large capacity portable power pack featuring Celestron’s LiFePO4 battery technology
- Powers your telescope for up to 17 hours
- Features 2 USB ports for charging other devices, plus a 12V car battery adapter port
- LED light panel provides bright white or red LED illumination for up to 25 hours

Must have item
Wednesday, 26 May 2021  | 

It's a great bit of kit , I all ready have the smaller one to power my telescope for 10 hours so this bigger one powers for 17 hours so when away from home it gives me 27 hours it's no were near as heavy as a lead acid battery, the power pack came be used with anything needing 12 volt or a usb port
It's not cheap but so worth it's price it will out power a lead acid battery and last longer so will not need to be replaced as often can be left flat not like some power pack , so it you need portable power this is what to get

Canít tell if the item is faulty
Thursday, 13 May 2021  | 

I bought this item as it was the best price around. An amazing super fast delivery service from Picstop. Very well packaged. Reason for 3 stars is that I think thereís a possibility itís faulty but as it seems to work, I canít be sure that it is. The fault Iím looking at is when fully charged, it shows 4 lights. However, immediately after taking it off charge, when switched on and do a battery status check, only 3 lights on and this is without any load attached. It also runs out of supply a little quicker than I expected, almost like there may be a bad cell inside not charging correctly, who knows. I donít have a second one for comparison so am unable to verify. Richard

I may have some good news to report back. I have experimented with charging to full capacity and it would seem that when the unit is initially switched on, it shows 3 lights, however when left to settle and then press the "charge left" button, it shows 4 lights 🙂.
It's now been about 8 hrs switched off and not on charge. I have switched on, no load, and waited a few seconds, did the "charge left" button and still 4 lights so I believe it's actually ok.
It must just be an initial start up when switched on, that the unit says it's only 75-100% charged, hence the 3 lights but resumes back to 4 after a few seconds.

Excellent Power Pack
Tuesday, 15 September 2020  | 

This is an excellent product, well built, rugged rubberised case will withstand any knocks, useful selection of output ports. I will be powering my dedicated Astrophotography camera, focus motor, image acquisition mini PC, and guidescope with this. The scope has its own internal battery, but I could use this battery if the other one is running low. Well worth the money.

Excellent device
Monday, 4 May 2020  | 

Does exactly as it says. It could be improved if one of the USB slots didn't have a cut off switch so that it could be used as a power, rather than a charging source. I couldn't use it to power a Star Adventurer mount. Brilliant nonetheless.

Good product at great price
Sunday, 15 December 2019  | 

Bought to power a mount, camera, usb hub and dew heaters through the Pegasus Pocket Powerbox. So far no issues, looking to have power for about 4 hour imaging runs. Price 15% lower than most competitors, what's not to like?
