Review on 🔋 Riiai 11000ma-h Mini Spot Welder with Adjustable 80 Gears | Portable Spot Welding Pens | Battery Spot Welder with Type-C Charge/Output | Includes 5M Nickel Sheet & 4X4 Holders | Quick Release Pen for DIY Spot Welding by Daniel Pyfer

So far it has done an excellent job of welding even thick conductors. There was one complaint about the interval but mine dropped to 0.5 SI, I wish it would drain the battery to 50% after a while for longer life, but it also works as a USB battery so it does easy enough to empty. it's with some kind of load. The most annoying lateral orientation of the terminal. It would be much better if they came out at the end.
