|Average Rating (12 Reviews): |Power Tank 7.2Ah SLA Battery

This device is quite basic and will fulfil many users' needs. It is clearly marked with the instruction to keep it charged and to regularly recharge even when not using the pack - DO NOT INGORE THIS!
I bought a second hand SkyWatcher 10" Dob and the seller "threw in" this power tank. After owning it for a while, the battery discharged and wouldn't accept a new charge using the supplied mains charger. Determined not to be defeated, I opened up the unit and removed the battery to attempt a full recovery on a smart charger - and it worked! How long for, I do not know but investigating the output from the Power Tank mains charger, I discovered it was only delivering 12.04 Volts whilst it should deliver between 13.8 and 14.4V for effective charging.
If you have one of these Power Tanks with the Sealed Lead Acid battery, I would recommend using a "smart" charger which, due to the internal wiring, you can connect to the Positive and Negative output posts recessed on the back of the casing. There is no need to dismantle your unit! A "smart" charger may cost you £20-£30 but it will certainly extend the life of your SLA batteried Power Tank. Of course the real solution is to accept the additional cost up front and buy a Lithium Battery unit in the first place!
Great power tank for the price.

I've bought this together with my telescope and am impressed with quality and portability. It does everything i need it to do. Many thanks to Martin and team at FLO for help and support. Regards, Dee.

Compact, packed full of features and highly versatile. Still on its original factory charge after three nights observing.
If you need a cheaper alternative to far more expensive compact new power supplies, this is a great solution.
The 7AH rating is more than enough to power a Meade LX90 8 inch ACF SCT throughout extended observing sessions and has been quite outstanding so far.
As usual, great customer service from Anne and the team.
Ordered, dispatched without any delay and received in perfect condition within the expected time frame...great job FLO!

So far I've only used this to power my HEQ5 and it's done that job just fine. I've dropped a star because the instructions are rubbish and the LED indicators are ambiguous, ie the fully charged light immediately lights up when charging when it obviously is not. Otherwise a good unit for the price.

I already owned one of these bought about 9 years ago. I hadn't used it for a few years because I temporarily lost interest in astronomy and unfortunately the battery will not charge again. This is normal with lead/acid cells and because of the age of the old one would probably have needed replacement by now anyway. Looking forward to some clear skies as the evenings start to draw in.

Really useful power supply

This power supply is much more useful than I expected. Not only does it have car power point sockets and usb ports, but it has terminals to connect wires to.
The light is quite powerful, and the red light is useful for preserving night vision, as well as an emergency warning light.
It can be charged either by the supplied mains adapter or from a car power point.

Ideal for Astronomy and Emergencies

Having recently bought a Celestron SE8 nearly all the reviews recommended buying a Power Tank over using 8 AA batteries for better long term economy and reliability. The cost of the unit was much cheaper with FLO than any others I could find (£20 cheaper than Amazon!). Before purchase there seemed to be confusion in forums and reviews over whether needing additional lead as it talks about cigarette lighter but the lead supplied is all that is needed. There are 2 in-built sockets which take the cigarette lighter end and the other end fits the socket next to the on-off button (in SE5,6,and 8).
Only downside (and being picky here) is that once removed from storage area it's unlikely you'll be able to re-pack the connector lead it into the unit - but not a major drawback.
