Cordless Heat Gun, Uaoaii 21V Hot Air Gun w/ 2x 4.0Ah Rechargeable Battery, 4 Nozzle, Led Light & Suitcase, 2-Temp Setting Max 1022°F(550°C) Heat Gun for Crafts, Shrink Tubing, Resin & Decorating

This heat gun has really sped up my automotive wiring repairs and modifications. I use it mainly for heat shrink tubing. It is so nice to just grab this gun, take it to the repair and shrink the tubing. No need to drag out an extension cord anymore. This gun heats up super fast and has a really long battery life. The extra bonus over a wired head gun is you don't have to worry about setting it down, it stands up on the battery as a base. No worries about the end touching something and melting it.

I been have looking for a cordless heat gun for a while now. I have tried several on Amazon and never found one that met my needs. I mainly use a heat gun for heat shrink tubing and heat sealing tubing. And sometimes for other misc tasks. Then I found this one and my search is over. This fits comfortably in my hand and heats up quickly. It has 2 speeds and comes with two batteries. The 2 batteries are what I like because an issue I had with others was that the battery died while using it for a while. I then had to pause and recharge it and then back to my task. No more interruptions!! It does come with additional attachments which is nice also. I love the flat attachment (not sure what it's called). If you're looking for an all-around heat gun, this should be the last one you look at.

It is what it is. This is a battery powered heat gun and is not as powerful is an AC model, but it is great for removing labels from plastic bags and boxes, and for heat shrinking wire shrink tubing, and it is portable! The heat is not as hot as my other heat guns but that is actually better for not melting through tubing and plastic bags. I would not recommend it for paint stripping or anything that requires extended run time since it overheats if used continuously. It is good if you run it for 2 or 3 minutes then let it rest for 15 to 30 seconds. It is very stable standing on its battery, so I just leave it sitting on my workbench where it is quick to grab when I need it! After use, I stand it up again to cool! No cord to yank it off the bench with or for me to hit and cause it to accidentally melt something! I have used it on several cars, boats and trailers to seal the wiring, and use it every week to remove Amazon labels from boxes. My main concern has been that, like other non-mainstream brands, I may not be able to find batteries for it in a few years when the included ones fail. Many thanks to the Amazon Vine reviewer who noticed that the batteries have the same connection as Makita batteries! Now I can get good quality replacements if I need them! I also have a 20V wet/dry vac that uses this battery! Battery nerd time: The 18650 Lithium cells used in these packs are 3.6V-3.7V nominal and 4.2V fully charged. Battery packs like this use 1,2, or 3 sets of 5 cells each to provide 18.5V nominal and 21V fully charged. The protection circuit in the battery drops the fully charged voltage to around 20V. 18V, 20V, and these 21V batteries are all the same type of battery! Marketing dictates how they are labelled, and the only difference is in the quality of the cells and the protection circuit. Mainstream batteries tend to be better quality, have a measured capacity closer to their labeled Ah rating, and last longer, but cost more!

I ended up not needing to use this for my project, but I did test it out before returning and the gun worked great. Plus the case for the whole set was really slick. I’ve used lots of heat guns over the years, and this one definitely looked the nicest. Big fan of it being cordless!

Constantly overheats after a couple minutes and you have to let cool down to be able to use again it's a piece of crap do not buy it. Cannot get any work done with this thing.

Update July 20: TL/DR -- had a bad unit and battery (x2). Since I posted my review (see below) about my purchase the company contacted me. They read my review and offered to replace my heat gun + battery (x2). Replacement battery and heat gun NOW WORK the way they're supposed to. I was surprised the company actually read any reviews, let alone reached out to any customer (me). Story short, replacement unit arrived today. So far, so good. Kudoz to the company for reaching out and sending a replacement. TL/DR it gets the job done. However... I experienced the same issue another customer showed in his video review - battery has few bars and unit will not power on. On a full charge unit does works as expected. I wasn't expecting too much from the knock-off 21V 4ah batteries included, to be clear. They do work but with just a bar or two only it's hit and miss. Low quality cells. But ... this heat gun is compatible with Makita 18V battery series so for me it's a win. looked at a couple of cordless heat guns including Ryobi and Milwaukee. Neither has lock-on feature. Makes no sense to me. For my line of work i needed a cordless gun. Ever tried shrink wrapping wires outside in the wind? Frustrating. Ever been too 'lazy' to drag an extension cord outside just to use corded a heat gun for a few wires? Frustrating. This heat gun, light-weight and compact, does what it's suppose to do. Three stars b/c of battery issue first day. Does the job. /bklyn👑

Esta pistola de calor inalámbrica es ideal para proyectos caseros, viene en funda rígida, duración de la batería aceptable, buen nivel de temperatura, trae boquillas, funciona correctamente, gran compra.

I charged the battery (it came with two plus charger), then tried it in the heat gun very briefly and it revved up fine. However, a half-hour later, it was completely dead, tho battery indicator said it was full. Couldn't get it to work. After I charged the second battery, the same failure to launch after a quick test run. Something is wrong with this thing. Very unreliable. Wonder if it's just me or if other people had the same problem. Anyway, I returned it and for a MUCH cheaper "corded" heat gun.
