Smart Jump Starter Clamps, Automotive Portable Booster Clamp Cables Replacement Alligator Clamps with Intelligent LCD Screen for 12V Car Jump Starter 7AWG Wire

As emergency road assistant this works well so far

Husband needed this device earlier today, and it performed as advertised. It seems well made and also has an LED voltage display.

I have a number of jump starters, two I tested these cables on had different connectors - apparently these are not standard across vendors. This cable set has the "flat" on the outside, it of course did not fit on the jumper with the flat on the inside. (2nd picture)If your jump starter has the flat on the outside, these cables are amazing. The hinges are very sturdy plastic, hinge pins are stainless steel. The clamps have very strong springs, and lots of copper alloy on the teeth of the clamps. The wire gauge and insulation is impressive - and one note, when I was trying to get a close up picture of the clamp teeth I noticed the wire was about half as thick as the primary wire, and I thought I had a "gotcha" moment, but the I quickly realized that this was just a jumper run off the main wire to the other side of the teeth. It's actually good design.I forgot to get a picture of it, but there's also an LED display of the jump starter voltage which is a nice feature. I have no problem giving this cable set my highest recommendation as long as it the right connector for your jump starter.

I'm pretty sure the connector is a standard size for most of these lithium ion battery booster. It worked great for my old one. The clamps are bigger than my original one and the cord is longer. The spring tension is good in the clamps and they hold tight. The blue connector is the weak point on all of these cables. You have to be gentle as you remove it from the battery booster. These also have a digital readout of the voltage, which is nice.
