- Heatbank 9s Rechargeable Hand Warmer

This handwarmer has come in handy during the wionter months where my employer likes to keep the AC on year round. It has a few power levels (I don't have it in front of me) and can be used to charge USB A devices. It maintains a steady heat during use and is very comfortable to hold. It is a vast improvemnebt over previous models by zippo which were basically rectangle and much smaller. It does not add much weight to my laptop bag and is worth the price to be comfortable. Well made and will last if cared for.

I got this for my Dad who is diabetic and has a hard time keeping his hands warm. I think it's his favorite thing I ever gave him. He keeps it in his pocket almost continuously in the winter months, only giving it up to be charged. Single button interface, 6 heat settings: 1,2,3 single and double-sided. It charges with a micro-USB port, which it would be nice to see updated to USB-C for future simplicity, but not really an issue. I don't know how it compares to other hand warmers, but I do like the size, shape, and surface material. It fits nicely in the hand, provides meaningful heat for quite a while, and the matte plastic surface evens out the heat nicely and avoids getting sticky or sweaty.

Surprisingly nice for the winter. On the bottom settings it lasts several hours, and gets almost concerningly hot on the highest setting. Comes with a lanyard to wear around the neck. On cold days I’d tuck it into my shirt and combined with a good jacket I’d be super toasty in pretty cold weather (10s-20s). Biggest complaint is the battery isnt removable and no usb c charging. Got 2 to give to my GF who loves to sky, but she also does art and said they helped with keeping her fingers and hands warmed up for fine pen and brush strokes.

Work awesome as always...wish they were ubs C...

Heats up quickly and to with a range from pleasantly warm to hot! The included lanyard is okay and quite ugly but I didn't plan on using it that way anyways. It charges using micro usb which I regret - now I have to take another cable with me if I put it in my bag. The battery lasts long especially if you use it inside clothing on a lower heat level but even on the highest settings it is acceptable. The controls are also easy to use. Personally, the cost and charging cable would make me buy another product that charges via usb c and might weigh a bit less (~1lb).

This was much warmer than expected and I love it. On the low setting my hands were nice and toasty. I have not noticed anyone talking about how quickly it heats up either. Once you hit the power button it takes about 10 seconds before it is completely warm which is much better than the heat packs which take about 30 minutes. I am very happy with the battery life and being able to change my phone is just a great addition. The product is quite large, about 6in or so and fits in my hands well. Being made of metal the product is great quality and has a sturdy weight to it. Overall I love it for anytime I go out and need something to keep my hands warm.

Works well and no issues. I gave 2 as gifts and they are used all winter with no issue. Have been very happy with them.

I was very excited to get this. My first use of it was after a full charge. Of course, shortly after I bought it, the temperature rose from the 20s and 30s to the 40s and 50s. Needless to say, I started out I with the highest setting and used it the first time in my pocket as suggested. It only lasted an hour and fifteen minutes. I have since used it on lower settings with only one side heating as opposed to both and it seems to last longer although we had a recent heat wave in the 60s so have not been able to justify using it again. Other than being disappointed with the initial heat retention with maximum capacity, I love how it feels and fits in the hand. Being that the battery life was so short in the pocket, I cannot imagine using this outside of a pocket as the instructions clearly say outdoor use will impede its function. With only one side heated, it is still comforting so I will be curious how long it lasts. It is easy to operate with six levels for heat. Initially, I was using the highest level. Stay tuned.
