This heated jacket is excellent for the colder months as this heated jacket does get warm fast. Just putting it on and pressing the button makes this jacket very toasty and comfortable to wear. The left side where the wires and the arm goes into the sleeve might be slightly uncomfortable as the wire needs to be repositioned or else you will feel it and it is somewhat difficult to move it inside the jacket. The power bank this uses can be the one that is included with the jacket, or can use any USB-A power bank to supply power for the heating elements making this jacket much more versatile in terms of what power bank can be used.

This heated winter puffer coat is made very well. There were no loose strings or stitching, and the zippers open and close smoothly without catching on itself. The battery pack is smaller than most phones and rechargeable. There aren’t as many zones as I’ve seen on other heated coats, but there’s enough. I especially like that it has heat around the neck area. It fits true to size and can be for men or women.

The jacket is very lightweight and comfortable even without the heater! I've used the heater on a few occasions and found it to get pretty warm when the ambient temperature is 50 degrees. However, in 30 degree weather I found that it just feels more like body temperature but does still make a difference. The heater in the pocket is nice but wish it was lower - I have to raise up my hands in the pocket to feel it.As far as keeping warmer in colder temps - I think part of the issue is the bottom doesn't cinch with drawstrings so cold air can get inside. It looks like it has a channel and I may try to put one in.

I am 5'10" and got size medium. It fits well around my waist but does not go as long on my arms as I would like. The coat is a very basic coat, but it has really functional pockets on the sides for your hand as well as 2 inside pockets - 1 for the battery. The nice thing about the battery pocket is that it's placed around your side and a little more towards the back than many other similar battery pockets, which means it doesn't interfere or add bulk in the same place as the left hand pocket. So I like that thoughtful design to spread out the pocket positions, especially considering batteries can be quite bulky. I have used all sorts of batteries with this coat and all work well, but the battery that comes with it is quite slim yet still has a good capacity. The coat is easy to operate with just 1 press, and I like that the initial setting keeps it on high for 5 minutes before dropping down to medium. That comes in handy so I don't have to remember to switch it myself and conserves battery. The coat itself is just fine without using the heating coils. It is pretty well insulated and is made out of a good slick fabric that works well in the rain or snow.

I find this jacket to be one of the most comfortable I've ever owned. It is very lightweight (in terms of weight, not performance), fits snuggly (which I prefer; why let heat out the top or bottom), and is not at all bulky. There is an elastic cord (not adjustable) along the bottom that tapers the bottom of the coat to my hips. I am 5'10"/145 lbs, and the small size fits me perfectly. Another thing I like is that the battery connects to the jacket via a USB-A port, and not via a proprietary connector. This allows you to connect any external battery pack that has a USB-A output (so you can use a back with more mWh, or bring a spare battery pack, if you're going to be outside for a very long time).I find the coat to be warm, even without the heat turned on. I can't give a complete review of how well the heating works because we've had a warm fall, and the temperature hasn't gotten below 30 degrees (F) many days. I can say that I don't need to turn the heat on unless it's less than 40 degrees outside (and I'm a temperature weenie).There are only a couple of minor improvements I'd like to see. The first is regarding the pockets. There is one pocket on each side, and one inside chest pocket (on the left side) for a phone or sunglasses. I'd prefer that the side pockets were a bit bigger. They're roomy enough for my hands, but not for winter gloves. The second improvement I'd like to see is that the zipper pulls were more heavy duty. I'm always afraid the pulls (particularly on the pockets) are going to break off (they haven't yet). One other thing to note, that doesn't matter to me but may matter to some, is that the main zipper is left-handed. That is, the zipper pull is on the left side.Overall, I would recommend this jacket.
