About this product

Model:  lynxastro_2.1mm_2.1mm_pwr_1m

New thinner & more flexible 'Orange' cable!

Premium quality, super flexible, cold resistant silicone power leads in 1 or 2 metre lengths, with 2.1mm centre-positive DC jack to 2.1mm centre-positive DC jack.

Suitable for powering your mount or other compatible accessory from a Lynx Astro 4-port dew controller or Hitec Astro dew controller.

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 center 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. 


  • Rated up to 4 Amp.
  • Silicone cable remains soft and flexible, even at sub-zero temperatures, so is less likely to twist and tangle like cheap alternatives.
  • Slimmer and lighter than our regular 'orange' Lynx Astro cables.
  • 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. 

NOTE: Not suitable for use with the Celestron Lithium (LiFePO4) Powertank Pro (it's power out socket is deeper than usual). 

Please note: These cables are unfused. Please ensure your controller or 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.

Short connections
Thursday, 9 September 2021  | 

Seems like a quality made cable, unfortunately though they are unusable with Celestron PowerTanks as the DC connections are too short to sit securely inside the PowerTank's DC port and it just falls out at the slightest touch.


We explicitly mention this on our product page:

NOTE: Not suitable for use with the Celestron Lithium (LiFePO4) Powertank Pro (it's power out socket is deeper than usual).

These cables are not suitable for that purpose, if you wish to return the cable for a refund please get in touch.

This is a brilliant cable to replace my power cable for my AzGti mount, the silicone rubber casing ensures no knots or snagging. It oozes quality and double insisted around the jack plug joins, real nice accessory for your setups.

Quality cable. Used in sub zero temperatures and remained completely flexible.
Jacks are well fitted and shrouded and fit sockets extremely well with a satisfying click.

The best astro cables
Tuesday, 7 April 2020  | 

These rubber orange cables are excellent. I need a few more to fully replace the stock ones that came with my Pegasus pocket powerbox, not that there's anything wrong with the stock ones but these ones are perfect. All lynx astro cables I've bought have been outstanding quality and easy to deal with.

Celestron NexStar SLT 6 SCT
Sunday, 9 February 2020  | 

This is a really nice Cable, it was meant to replace the Standard DC Cable, which came with the Celestron Lithium 7.2 Ah LiFePO4 Powertank (smaller model). The supplied cable tends to stiffen with the cold at night, and can be arkward. After discussing compatabilty with FLO, I decided to give it a try.

However, after some effort and fiddling. I found the cable's Plug itself is just not compatible with my Nexstar SLT Mount. At the Power Tank Socket, there is no problem, the Socket has a compression hump/spring which moves back to accommodate the plug as it is pushed in, at the Telescope's Mount, this DC Socket is a slightly different design for some bizarre reason, and the front of the Cable's Plug snag's on the internal compression cutaway, preventing the already shorter shaft length of the Lynx Plug, from Fully locating into the DC Socket. I can only comment on my current SLT Mount which was purchased 5months ago. I was really disappointed about this, as the Lynx Cable is a first class product, and more visable in the dark. I have now read some postings on the Internet regarding Celestron's DC Sockets, so do some research, as it's worth your while being aware of possible problems. I cannot fault FLO for their complete understanding and refunding the purchase cost. 10/10 for true customer service at its best.

An end to cold plastic cable knots
Wednesday, 18 December 2019  | 

One of the biggest banes of my astro life is tangling of stiff plastic cables. All these Lynx silicone cables are a joy to handle, They retain all their flexibility in freezing conditions and, as far as I am concerned, are worth every penny. I also have Lynx cables for my mounts, and dew controllers.
