About this product

Model:  lynxastro_12v5a_ln_psu_uk

Our BEST 12v / 5A Mains Power Supply! 

A medical grade PSU that delivers smooth, dependable, low noise power. Even at sub-zero temperatures. 

UK version supplied with an UK style mains plug. Also available as a US version and a EU version. Please ensure you choose the right version for your location.

Regular power supplies with 12V nominal voltage are designed for indoor use; when used outside in the cold, their voltage drops (at -10°C, the voltage output may reduce to only 10.5 V). This reduction in voltage can cause a mount’s motors to behave erratically. Indeed, most apparent faults with modern mounts can be traced to an inadequate power supply. 

Suitable for use with most modern computerised GOTO mounts with power requirements up to 5 Amps, including the following:


Star Adventurer GTi
HEQ5 Pro
NEQ6 Pro
EQ8 (with optional adapter)




Advanced VX
CPC Deluxe

Note: This power supply has a fully enclosed plastic casing but should not be used in wet conditions. 

Supplied with a 2m, 3-pin UK-type C13 plug. 

Total cable length 2.9m.

Good power supply
18 April 2024  | 

I bought two of these to supply power to both an AM5 and ASIAir. Great power supply with the caveat of the cable length from the adapter to the AM5/ASIAir etc. could be a little bit longer. But on the whole, the adapter does the intended job.

Great power supply for my Star Adventurer GTi
16 September 2023  | 

This is a very good power supply and works extremely well with the Star Adventurer GTi, I would recommend this to any one who needs a 12v supply for their mount providing they do not need more than a 5A supply.

As usual FLO provided excellent advice and speedy delivery. As a company I rate FLO very highly and definitely the best company I have ever dealt with.

Strong and sturdy

I ordered this adapter as the cable I had the sheath had broken away exposing the wires. I can honestly say I canít see this happening with this one I have from FLO. Itís very well made and is very strong and sturdy. Delivery was quick as always from FLO ☺️

Nice power supply but stiff cable.
18 September 2022  | 

This appears to be a very well made power supply. Up to now, I have just used it to power my HEQ5 Pro and it works fine - I have some more kit on the way but I'm sure that its more than up to the task. After unplugging it the green LED stays on for some time which I would guess is due to a beefy smoothing capacitor, which again is a good sign. The only problem is the rather stiff captive DC power lead and not particularly great plug. In my mount I have to be careful with cable management as it pulls on the (rather wobbly) mount socket and can easily come out. Either a more flexible cable or an L shaped plug would have been better. I have bought one of Lynx Astros excellent silicone leads and some female-female connectors and am going to wind up the captive cable and use the silicone one up to the mount instead. This has a far more secure connection to the DC socket and is very flexible so doesn't tug at all. All that adds £20 to the cost though. You'll be fine with the stock one if you carefully cable manage.

It does the job

A relatively small, but so so useful addition to the growing collection of accessories ... and it does exactly what it's supposed to do.

It works, but Ö
12 October 2021  | 

The power supply works fine, in that it supplies adequate power to my new Celestron VX mount. However, the connection to the socket on the mount is not really up to the job. The slightest movement of the plug and the connection is lost, which means having to go through the setup and alignment routine again. The problem seems to be that the plug, although it clicks on insertion, does not go in far enough and remains very wobbly; there is no ring on the plug, unlike the car battery connector cable supplied with the mount, which enables you to screw the plug on to the socket. If you accidentally brush against it you lose your power. So, if you want a mains power supply for your VX mount, make sure you get one with a screw locking ring on the plug to hold it in place

Good Quality Supply
29 September 2021  | 

I bought this supply to replace an old one that was causing interference problems with my Lynx Astro EQDIR cable and AZ-GTi mount. I'm glad to say it has done the job, good quality supply and the mains cable is reasonably long making it easier to use with a mount than some cheap brands that have very short cables.
