I purchased a 7.2 ah powertank back in July 22 it worked great until recently, an issue with holding charge occured, reported this to the FLO team the response was second to none the powertank was picked up by a currier organised by FLO and within a few days a replacement powertank was shipped back to me with no quibbles outstanding service from the FLO team.

As it says on the tin. With USB connections can charge or power other devices. The red and white lights have two brightness settings each. The lowest red setting could be a little dimmer though.

Already have a couple of Tracers rated at 125WH, but certain airlines such as Air Mauritius don't automatically grant above 100WH. Bought 2 of these to avoid any risk from vexatious staff at Airline check-in. They performed flawlessly driving my trusty AZ-EQ5 GT mount. Havng 2 meant I could Park, Swap and Start from Park pretty seamlessly and carry on observing while recharging. Once again a flawless service performance from FLO. Spent a whole month on the Tropic of Capricorn with the VMC200L observing effectively overhead oppositions of the gas giants wearing shorts all night.

After investigating options for powering my HEQ5-Pro mount when observing away from home, I decided on this Celestron Powertank. Chris at First Light Optics responded very quickly to my questions, to confirm that it was compatible with the mount, and estimated it would give me 3 to 4 hours of operation. It arrived, well-packed, two days after I placed the order. The unit is slightly bigger than a pint glass, not very heavy and seems quite ruggedly built. I charged it and connected it to the mount, and initially thought it wasn't working. On reading the manual more closely, I saw that to start the device I had to press the power button twice in succession, not just once! Everything then worked perfectly, and I did a couple of tests to see how long the drive would operate before the battery discharged. Using only the RA motor, without any rapid slewing, the mount ran for over 9 hours. Obviously, if I did a lot of fast slewing between targets, the run time would be less, but I'm very happy with this performance. The red or white LED light panel on the side of the unit is a useful feature. The fixings for suspending the tank or attaching it to a tripod leg are usable but could be better. The USB charging ports can't be used while driving the mount, which may be an issue for some, and the remaining battery charge can't be tested while driving the mount, which is annoying. I haven't yet used the unit in the field, but based on my tests I think it will do everything I require. The lithium-iron-phosphate battery technology in the device is apparently capable of 2000 charge cycles, but mine won't reach that number for many years so I can't confirm it.

FLO yet again, speedy in response to questions on order, processed the order fast with efficient delivery. Looking forward to using this with new scope when it arrives. Thus far looks durable, sturdy, charged fine and all excellent as expected.

Excellent product wish I'd invested in one much sooner, it'll save me a fortune in AA batteries

I absolutely love this powerpack- it straps to the tripod leg of my scope and the choice of red or white light in two brightness settings is very useful. It’s fantastic to be able to take my telescope anywhere without having to use batteries or plug it in. The powerpack is sturdy and not too heavy - just what I wanted. It arrived very quickly and well packaged - thank you FLO!

This powertank was recommended by FLO for my Skywatcher 150i mount and scope. The mount will eat through 8 AA batteries quite quickly on a decent nights observing. However, this little beauty will power the thing for 10 hours from a charge. It's easy to use, attaches easily to the tripod leg or has a handy hanging capability. You can't go wrong with this, with it's built in LED lights (white and red) and bonus 2 USB ports to charge your devices. Spot on in every way.

Fabulous. Product, Highly Portable, Convinient and Easy to use. Slightly overpriced though. As always ,Fast delivery by First Light Optics.

This Powertank comes with an instruction booklet, a mains charger with 4 mains adapter plugs, a hanging strap, a tripod leg strap and a 2m DC power lead. It has a rubber lid which lifts up to reveal the power button, the light button, the charge state lights and two USB charging ports. There is a single 2.1mm inner/5.5mm outer DC socket used both for charging and power output.

What is good: It's very light weight - about a quarter of the weight of the old-style powertank. It's convenient to fit on the tripod leg. It works as a red or white light lamp.

What is not so good: The rubber lid does not stay up, which means you can't see the status lights to check when it is charging (lights flashing) and when it is fully charged (all the lights stay lit). The power button is shared by the on/off function and the charge indicator, so, in use, you can't see the charge level without switching it off - so you lose all your telescope settings. The power lead doesn't have a screw-on connector to ensure a secure connection at the telescope end.
