SPARKING DC 5.5 x 2.1mm Car Charger Power Supply Cord - 12v -24v 4FT Cigarette Lighter Male Plug to DC Connector 5.5 x 2.1mm Cable

This power supply cord was recommended by Skywatcher Telescopes Tech Support to power my "go to" Skywatcher Telescope mount using a Lithium Battery Power Supply. The power cord works great and is nicely constructed. I highly recommend this seller and product.

This is identical to the HDM/Breas travel charger for the Z1 and Z2 travel CPAPs, but at 1/3 to 1/4 of the price. I tested this with my Z2 Auto travel CPAP and it powered up and ran perfectly, both with the engine running (providing the machine ~14.1V of power) and with the engine off and the car in accessory mode (providing ~13.5V). I also bench tested the Z2 Auto with an AC to DC converter which provided a steady ~12.7V (see photos). The CPAP still powered on and ran perfectly. The AC adapter included with the Z2 CPAP provides 15V/2A of power, but it seems HDM/Breas designed the machine to work within a range of voltages, since the official HDM travel charger provides unregulated power straight from the cigarette lighter, exactly like this one does. My machine certainly didn't mind running on as little as 12.7V or as much as 15V.

Purchased this to use with a travel CPAP for off-grid and power outage (to use with a portable power station). Using the (DC) USB-C plug on the PPS is much more energy efficient than the AC plug. This cable worked, but didn't fit snuggly into the CPAP like other cables do. I'm still rating 5 stars because it's no fault of the cable that it didn't fit my machine - I just need to do more homework first. Overall, it seems like a high quality cable.

Bought this as a spare charger for my husband's truck. We don't use it often because it does get warm to the touch when charging but will work in case of emergency

I had two different cords that I found in my collection of electrical odds and ends and neither could provide a solid electrical connection under load while driving. Took a gamble on this one and it is much better. The side contacts are stiffer and the end spring is stronger than either of the cords I had. Goes into the socket solidly and is providing solid electricity even when the Jeep is bumping along. The red LED is an added bonus so you don't have to guess if you have it powered.

Works great connecting my Jackery battery to my ZWO AM5N telescope mount.

It's fine, thank you very much, I'll give it 5 stars. I've been using it for several days and I'm very satisfied.
