Mini Solder with Rechargable Battery (Black)

This thing is way more mini than I anticipated but it works amazingly well! I had no idea vape batteries were being sold as soldering irons but it’s actually perfect because I was looking into soldering irons for some DIY projects a while but I would use it so infrequently, it wouldn’t be worth the money to invest. Then my 510 pen battery died on me so I thought to check amazon and I find this godsend of a device! The variable voltage has saved my throat because even on lower heat settings with the pen, my carts would hit so harshly. Being able to lower the voltage to 1.9-2.1v level seems to be perfect for a more mellow throat feel with still a strong hit of visible vapor. And my carts seem to clog all the time but with this battery there is a pre-heat function that really helps clear them so easily! Five taps to turn on and two taps to preheat. Screen also shows battery levels and it charges fast. I haven’t used it as a soldering iron yet but it’s just a metal rod that screws in like a cart to attach to the heating element so I’m sure it will work. All around an amazing product! Better than pricier weed cart batteries I’ve got at the dispensary and you get a tool!

I've finally found my new favorite 510 battery ever. The mini has to be the most discreet and certainly the most adjustable battery I've ever used. USB3 charging port. Being able to adjust the voltage in .1V increments and set the voltage from 4.2V down to 1.8v is a gamechanger, afaic. To top it off, it has the most user friendly silicone rubberized outer covering that is large enough in diameter that it's a perfect fit in your hand and no worries about dropping it. I am so impressed that I went back and ordered a 3-pack because who knows how long these will be around. Two thumbs up.

Heats up nice and quick, screen, buttons, and voltage function well, and is small af that its smaller than my palm. even turns off on its own after a couple minutes in case you’re too low to remember. definitely recommend buying if you’re looking for a fun sized, discreet battery for your shopping cart (or for soldering).

It does not work. I charged it, did exactly as I was supposed to, and it did not give off any heat at all. I don't understand how Amazon is selling such crap products.

This chargers my iphone, AirPods, and tablet very quickly. Purchased for a long airplane ride and have no complaints. It’s heavier than I expected but for the quality of how it works, it’s totally worth it. My daughter has the same one and hers works great too.

Came fully charged..way smaller than expected but love it

The friendliest battery ever.

Couldn’t be better. I don’t solder but it suites my purpose!
