HeatBank 9s Rechargeable Hand Warmer

Use for winter dog walking when wind chills are often below zero. Much warmer than the disposables and this seller had a great price. My last pair of this same brand lasted just over 2 years. Does take time to recharge (30-40min) but they work for at least 90 minutes on full heat. I keep them in my coat pockets as they are fairly large but perfect to wrap your hands around with heat on both sides.

This works far better than I expected; exceeding the chemical packs and lighter fluid alternatives by far. Heats up quick. I have only used the low and medium settings; high/hot must be incredible. This is UL listed so I have a bit more faith in the LiIon battery quality. The phone charging capability is nice, but given the choice I would give that up for a small LED light; that would be perfect. I have used only on ~30 minute dog walks so far. After 4 walks it still has 2/3 battery indicators lit. I don't know yet how long it could go running for an extended time.

I got this for work and it works great. The battery life just depends on what setting you use it on. It has 6. Low, med, or high and then single or dual sided heat. It does get quite warm on higher settings so I usually just use it low and single side heat and leave it in my pocket or around my neck. On the low setting it lasts a full 8 hours. Not sure how long on high since I don't need it that warm.

The heat output is impressive and great when camping if you have a way to charge it each day. I imagine on lower settings it could last multiple nights in a sleeping bag. Great for sporting events. My only complaint is that it uses the old style charger rather than current USB-C which is becoming almost universal. I’m hopeful they will come out with a new version. (Not the end of the world; simply requires carrying more cables or adapters.)

Bought this zippo hand warmer in May 2025, and now it’s January 2026…. And it’s still working. This hand warmer has two side heating and an option to heat just one side. With just on the lowest settings with heating on both sides it will heat 4hours or more, haven’t tried how long the single side heating will last. Only bad thing about this…is that it’s micro usb and that’s about it. Bought another one of these since I like it so much.

Works great

I have been through 11, yes, 11 in 8months time (this includes purchases and warranty replacements- I still have three to go and they are on their last legs), using one, once a day, for an arthritic joint and then recharging it. They heat well, give good temperature, if not too much on bare skin, but the people with EVERY SINGLE ONE is that the charging port wears out after about twenty charges or so. I’ve used the cable it comes with, I’ve replaced it when it stopped working with expensive cables, cheap cables, I even dissected one to see if I could readjust the fitting or contact (I can’t). The port stretches out or otherwise deforms in a way that unless you do a dance like adjusting old rabbit ear antennas on televisions and then Hold it when you got the sweet spot, it won’t charge. It could be a great product, but this flaw makes is essentially disposable. So disappointed in these. They help really well in spot treatment of arthritic points, and being portable instead of being tied down with a heating pad, but unless they fix this issue they aren't worth it, they will fail just as you are getting used to them- which is a shame because all of the other components are put together well, it’s just that the charging port is it’s Achilles heel

Great hand warmer. Lasts a long time. Good for golf or just being outdoors.

Funciona muy bien, cuando hace frío se me ponen heladas las manos pero con este aparatito ya no sufro, en unos minutos las puedo calentar. Te lo puedes colgar del cuello y no te estorba, así si necesitas soltarlo un momento mientras lo estás usando o para tenerlo listo cuando lo necesites, está a la mano. No quema para nada, es una temperatura muy agradable.

Charging - The heatbank itself (input) charges quickly - For charging other devices (output) it works well, decent speed charging, not slow at all Heat - With the 3/3 heat setting, it gets very hot, uncomfortably so if you're touching it with bare skin. However this is very good for getting through clothing / gloves - At various points in time, I found myself hanging this from my neck, to warm my chest (getting cold/sweaty at night or simply cold outside) - You can set the heater to activate on 1 side, or both sides of the device. I guess this is useful when you put it in your pocket etc. when you only need the side facing your body to stay warm, as opposed to holding it in your hand. Utility - The strap is VERY useful as you can hang this from your neck and keep your chest warm - If you're someone whose chest can get cold/wet at night, this does a great job of heating up your chest + drying up your sweat Overall - GREAT product which I used on my 2-month trip, even in late autumn/early winter - Sturdy build, does everything properly

The Zippo fits snugly in one’s hand —- whether it is a little woman’s hand or a larger man’s hand. It heats up quickly and lasts a long while. I love the fact that I can charge my iPhone with the device!

My wife loves me for this little unit. She always has cold hands so this is perfect for her, and me too. With winter here, she never leaves home without it.
