Sumnacon Multimeter Banana Plug to Crocodile Alligator Clip Test Probe, 5PCS 4mm Stackable Colorful Silicone Banana Plug to Alligator Clip Test Probe Lead Wire Cable 1M

These test leads seem to be fairly good quality and are quite adequate for most electronics bench work. The wire size seems large enough to handle typical power supply currents, although no specific AWG size is indicated in the packaging. I purchased the 3 ft. set, and each of the leads had a measured resistance of around 0.2 ohms when tested. The wire insulation jacket appears to be silicone and is very flexible and easy to position. The alligator clips are good quality, with resilient springs and flexible insulation boots. The stackable banana plugs each have eight, small contact fins on the tip and rotate around the center post of the connector, which reduces wear over time when adjusting their orientation. All the plugs fit very snugly into the jacks on my power supply, and required some tension to remove. In summary, I would highly recommend these test leads as a great value for any type of bench work.

So I ordered these at the same time as a "JESVERTY DC POWER SUPPLY". These things rock! I ordered the 9.8 ft longer version and am happy with the extra length. These are very flexible and have a nice outer coating. For the modest price of roughly $3 per cable, I think these are a great value.

Great quality! Wasn't sure about the gauge---some listings will show a gauge, some don't. They give a vague "rated for 15 amps" --that could mean almost anything. Are you gonna get 2V drop? These are 14 gauge--NICE!!.I measured just under 0.4V drop at 10 amps test load, for the 6.6ft 2 meter cables. 16 gauge would have given just over 0.5V (according to the tables I used). There is some drop in the clips, and connections themselves, so I feel very good about these results.

These clips use a thicker wire than the J-hook clips, which makes them useful for power supply leads. The banana clips use the spring loaded expanding variety where the spring part floats on the central pin. This means the plug can rotate slightly without loosening in the barrel. The alligator clips align nicely and have good insulation all around. They stack well and retain in the barrel of a bench supply, even with another clip stacked on them. If you've had experience with banana plugs, you know they can be hit or miss, these definitely fall into the former category. My only criticisms are they could be a bit longer, 1M seems like a lot until you have a bench supply sitting above the bench and the wire doesn't quite reach. I think 1.5M would be a good compromise between too long and not long enough. I realize these are marketed as "meter clips" but the wire gauge is appropriate for power supply purposes, so I think these are designed for that purpose. The J-hook variant are definitely smaller gauge and designed for much lower current carrying needs, get both to cover all of your common uses. My recommendation to the seller: Put together a package of 1.5M clips with the alligator and J-hook, with larger silicone jacketed wire and sell them for $35. Include some sort of cable hanger/manager to hold them when not in use, and you'd have a great product.

The banana plugs are stackable and the crocodile clips made good connections. The wire is flexible even in cold weather and is of good quality. I use the red and black leads with my portable power supply. They handle 10 amps without overheating.

These are far superior to the ones that you find everywhere that are basically clones but sold under different brand names. For one, these use fairly thick copper wire that is low resistance. The average clips I find are between 1-2 ohms while my multimeter isn't precise enough to accurately measure the resistance of these, so they're much closer to 0. In addition, the banana adapter is superior as it isn't loose in the socket at all so it won't come loose accidentally like some of the ones I've had in the past. You can also stack the banana side so you can run wires of the same voltage to multiple parts of a circuit However my favorite part about these, which is why I bought them, is the actual alligator clip. Almost all of the alligator clips you'll find use this soft silicone material that's slippery around the clip, and it makes it hard to open plus it might slip off and they're overall just a hassle to use. These use sturdy plastic that doesn't move around, and opening the jaws (which also use a stronger spring than others) is easy because of the hard plastic and metal. Overall I have zero complaints about these and they are totally worth every penny over other cheap ones.

An excellent products.

I use these for charging our LiFe aircraft batteries. The cables use a high quality cable, banana plugs, and alligator clips. The molding around the banana plugs allow for stacking of cables as those ends have a male and female on the one side and seem fairly high quality. The molding on the alligator clips are amazing, I hate those stupid pliable plastic ends they always roll and make it impossible to open on the cheap ones. These have a hard molding around them and make it easy to secure on the terminals of the batteries. The spring on the clip end is nice and strong and they hold on to terminals well. The cable has a nice insulation on it and they are pliable making it hard to pinch the cable if it's all in a mess. They come in a pack of 5 and I love the colors. Overall very satisfied with the quality of these clips.
