Good but rather rigid lead
Does the job, as it avoids having to have the charger inbthe engine bay. But the quality of the lead itself is disappointing; for the price I expected the lead to be a lot more flexible.

Good but would like a waterproof cover on the female end
Good works well however bit disappointed that the female end doesn’t have the Ctek waterproof cover on it. Other than that it works great
User
Works well and of a useful length
Provided enough extra cable length to enable me to connect my car battery to my CTEK charger mounted on the wall inside my garage near to the up and over door sufficient for me to also be able to close the garage door with car outside. Useful to have and appears well made like my trusty CTEK charger.

Easy to connect up
Easy to connect up and enables charger to be kept under cove while charging.

Ctek 2.5mtr extension lead
This Ctek extension is a must if you do not not want to leave your Ctek battery charger under the bonnet when charging or you do not have close access to a mains socket, as the cable supplied with these Ctek chargers is not very long. The extension is well made and has comfort plug push in connections to your Ctek charger cable. Expensive for what it is.

Bad design
Not really impressed actually. There are no fastener clips, and shizz tends to get loose after you use them. Reminds me of my ex wife actually.
User
