510 Soldering Iron USB Cable therad Charger with Smart Charge Protection for Charging Soldering Irons 2PCS(Metal case)

I have broken so many of those plug-in, USB chargers by my dog, stepping on it and breaking it that these chargers have saved my life for vape pen charging

Cheap stuff. Stopped working after 3 full charges.

Worked just fine for my o-pen.

nothing special but it gets the job done

These are a similarly priced alternative to the black plastic version, same USB connector with 510 threading. While the presentation is much better than the plastic ones (metal, softer wires) it's the same nonsense with many of these products: one charger was perfect and delightful, the other has off-center threads and a wonky LED indicator. That's always been the tendency in ordering chargers like these on Amazon, one unit will be acceptable, the other questionable, always a two-pack. You won't convince me it's not intentional, but what a ridiculous way to make money!

Work exactly as advertised, charges my soldering iron as needed. Takes a little bit longer then i thought it would, but that isn't any issue for me. It also turns itself off when it finishes charging.

Only one Worked and it worked once, never worked after. bad product

I am surprised actually, I expected them not to. I guess I am an Amazon pessimist. I was worried about nothing. These delivered in their function. Standard 510 thread with a USB on the other end. I am using them to charge my miscellaneous batteries, but I don’t think I will use it with my favorite go to, which has its own ‘special’ charger. If you have batteries and have lost all the damn charging dongles, pick up these. They work.
