We buy a lot of these and have not had trouble with any of them. Works well in temperature extremes, no issues. Size/length always as listed.

Wasn't exactly sure if this was the right size. Took a chance, knowing it was returnable if I purchased it by mistake, However I guessed right! Works perfect.

These cords worked well to power to small battery operated fans I had and I plugged them into my ECOFLOW portable power station. The cords were long enough for what I needed, and worked perfectly.

The 5521 connectors fit perfectly with the Starlink Mini. I needed a bit of an extension cord to make it from the LiFePO4 batter to the Mini.

The one that came with the unit doesn't have a size, so hay to return

Cables that are exactly as I expected. They work and the end of the cable is securely attached as it should be. Nothing unusual, just a regular power lead, would buy again if I needed more of them.
