About this product

Model:  lynxastro_pwr_skyw-mnt_cig

Premium quality, super flexible, cold-resistant silicone 2 or 5-metre replacement power leads with Cigar Lighter plug or M8 Ring Tongues to 2.1mm centre-positive DC Jack.

For use with Skywatcher SupaTrak, AZ GoTo, EQ3-2, EQ5, HEQ5 & NEQ6 series mounts. Also suitable for ZWO-cooled cameras and other astronomy accessories that require a 2.1mm centre positive, 12v power supply.

Lynx Astro power cables remain soft and flexible, even in the sub-zero temperatures often experienced by astronomers.

Each lead is individually tested for electrical continuity, shorts and power load during manufacture. 


  • Over-spec 12 amp rated silicone cable remains soft and flexible, even at sub-zero temperatures, so it is less likely to twist and tangle like cheap alternatives.
  • High-quality cigar-lighter plug with red power indicator and cable-restraint to prevent damage. 
  • Cigar-lighter plug rated to 5 amp, fitted with a 5 amp fast-blow fuse.
  • Cables with ring-tongues are fitted with M8 Ring Tongues (fit over M6 and M8 connector posts)
  • 2.1mm Jacks have over-long heat-shrink sleeving applied for additional protection against dew and damp
  • Every lead is individually tested for electrical continuity, shorts and power load during manufacture. 

Please check your product's manual for use and suitability. 

Please note: Cables ending in ring tongues are unfused; please ensure your PSU has a suitable fuse or circuit breaker to protect your mount's electronics. We accept no responsibility for equipment damaged as a result of using an incorrect cable, incorrect power orientation or connection without a suitable fuse.

So flexible
08 February 2024  | 

Great cable, remains flexible sub zero, not sure how low, UK based, but all other cables had become stiff and unmanageable. Only caveat is make sure you get the 2.1mm or 2.5mm as needed they are different items, I ordered the wrong one initially.

The cable was delivered quickly and well packaged from FLO - excellent service. The cable is as described. The fittings at each end are very secure and the fitting into the ASI / AM5 is secure and robust.

The Best Iíve Found
24 October 2023  | 

These arenít the cheapest cables but you really do get what you pay for. It wasnít much more than I paid for an iOptron cable but itís a massive upgrade.
Iím going to upgrade all my power patch leads to Lynx now, Iím that impressed. The other night saw the temperature here drop to zero but these cables were still totally soft and flexible while my other cables (Pegasus and iOptron) were stiff and difficult to manage.
If you want to get the best out of those cold, crisp winter nights then these should be on your wish list.

Best power leads Iíve encountered
26 February 2023  | 

Ok firstly, totally my mistake, I ordered the wrong size dc plug, needed 2.5mm but ordered 2.1mm. Easily resolved with an adapter.
These leads are great, they stay flexible in the cold nights and you can feel they have good strength and quality and feel assured they will deliver the power needed. Another good quality is the way they plug in at either end, you can feel that theyíre in securely and wonít fall out without a good tug. The only slight change from previous ones Iíve had, is the led light on the cigar plug is much brighter but it actually acts as nice glow light to the pier as itís situated on the support arm below. Excellent quality and I have come to expect no less from Flo as their products have always been reliable and well made/built. Thanks Flo

Ring Tongues not far enough apart
03 February 2023  | 

I bought the version with ring tongues to use with a 50Ah LiFePO4 battery. Itís a well built cable, but arranged so that the maximum distance between the ring tongues is 12cm. My battery terminals were 15cm apart, so in order to use the cable I had to snip a sealing band and make a slit in the silicone sheath. It now looks a mess.


This is a first for us - these are usually more than far enough apart for most uses so this must be an exceptional use case - if anybody else has similar issuses or batteries with terminals that far apart please contact us prior to ordering and we can produce a custom version of this cable.

Excellent quality

Usual excellent quality and sercice from FLO. It is a tight fit into my Az Gti wifi mount but not a bad thing, certainly won't pull out accidentaly.

Switchcraft 'Z series' doesn't always make a secure connection, depending on your device.
06 July 2022  | 

Couldn't get a secure connection with this lead to my AsiAir Plus or Pegasus Power Box advance, compared to cheaper leads that do. A little bit of applied pressure and the power is lost. Lead looks high quality otherwise.
