clamps are super heavy with strong clamping force, the relay actually stays one better than the original that kept toggling on and off

although these cables don't fit my GooLoo jumpstarter and had to return, I was impressed with the quality for the price. If standard EC5 connection is needed, i would not hesitate to purchase these over the more expensive ones available.

Did not work first time I used it. After checking the connection, I tried again and still did not work. A check with a continuity tester revealed the red wire appeared to have some type of disconnect in it. had power at the beginning but not the end. Tried resetting according to directions however it never worked. They claim to have a warranty except nowhere on Amazons site does it give you a link or contact info for UpBoost Update I was able to find a contact for Upboost using Google after exchanging emails they did issue me a refund. I'm changing my rating from 1 star to 3 because of their customer service assistance.

Amazing clamps. Even works if the car battery voltage is too low to register with its overide boost button. Perfect for me as a professional collection driver if I turn up to a completely dead car with this boost button it will force the jump start overiding the safety system.Never get stranded again

These jumper cables feel well built with good thick cables and chunky clamps.But the power cable is attached to a metal plate which in turn is screwed.Onto the clamps by 2 screws. On opening the clamps, the top screw on both clamps fell out.And cannot be screwed back in as a little bit of plastic the screw was screwed into came with the screw. This just leaves one screw instead of two holding the plate on to the clamp.So, Beware.
