TUOYAO Battery Cable Lug Crimping Tool,Electrical Lug Crimper with 60pcs Wire Lugs and Heat Shrink Tubing for AWG 10-1/0 Battery Terminal,Copper Lugs Terminals

This is a well made tool. And with the multiple settings, I was able to do multiple jobs; connecting terminals for 1/0 AWG welding wire for an inverter installation and 2/0 for an auto battery. I believe there are 5 different settings for different size lugs. Easy to use and change for different wire sizes. Two things to watch for: 1) As you're gripping the lug to crimp it, make sure it stays in place on the wire. It's hard to see the position of the lug and pretty easy to wind up crimping half way off of the wire. 2) In order to get the tool around the lug you have to open the jaws all the way. You need about 25 inches of clear space to open the tool wide enough. So, not great in tight spaces.

I have used this crimper on large gauge wires for a few weeks now with ZERO COMPLAINTS ON PERFORMANCE. Very easy to use, well constructed and strong enough to crimp large connectors easily. The ONLY COMPLAINT so far is that the numbers on the crimper dies do not conform to standard wire gauge sizes. Otherwise a GREAT TOOL at a VERY REASONABLE COST..

Nice good tool

Very good

What not to like about this crimper. It works as advertised an the lugs and shrink wrap are of good quality. 02/17/25 Crimper is still working well, just found out with a file the lugs are copper washed brass.

These work well. I’ll probably never use most of the brass fittings that came with it.

I used this tool to crimp about 80 lugs from 1/0 to 10 ga. I only got about 10 nicely formed crimps. I feel comfortable with the crimp connection, it just didn't perform a uniform factory looking crimp. I think there may be issue with metric over ase, or different mfg lugs. Either way, it did work and I saved on the cheaper price of this tool.

There must be a fever somewhere that tools of this quality are being sold so inexpensively. Easy to use and easy to squeeze and I'm over 60, and a computer programmer with very little upper body strength. But I was able to get the included crimps on the wire, a #6 and #8 is all I've done so far. But makes a nice tight fit.
