Heatbank Rechargeable Hand Warmers

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.

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

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.
