X - Heavy Duty Jump Starter Replacement Cables | Double Layer Copper Coating | 12V Car Battery Booster Jumper Emergency Cable | EC5 Jump Starter Compatible

Great item

These work great! Made sooooooo much better than the original pair that came with our charger, and broke after literally 4 uses over the span of about 16 months. So glad we found these!

These are the right cables you need with the 6000A jump box

First I never write reviews and hardly ever bad ones but I am so surprised by the quality of these clamps I had to write one. The clamps are solid metal clamps all the way down with plastic covers, the springs are strong, and they open really wide. Someone else said in a review the wire are short while they are slightly shorter than the pair I'm replacing the clamps are much bigger so they end up the same size. These are a steal at $9. I definitely recommend these

I was surprised at the weight of the package when I got it when opening these have thicker cables a beefy safety plug and the clamps are basically all metal with strong plastic handle covers and metal rivets. These appear to be 10x better than what the pack came with and 8x better than the previous replacement set. There is "reset" button on the connector box which supposedly allow to bypass the safety protection but that doesn't actually do much if anything. I tried them and it just showed a red light. Support took awhile to answer but Amazon did quickly send a replacement unit that I promptly tried. What I have found is that apparently some jump packs have lower voltage output that causes the the Cables to fault out.

I will say these cables are super heavy duty and well designed. Only issue is I am still trying to purchase the UPBOOST jump box they are designed for that is not available at this time through Amazon. The company is from the UK and does not ship currently to the United States 🇺🇸. The company offers a lifetime warranty on the product, which is not seen too often anymore.

These did not work. They seem like very good quality but did not jump my car.

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.
