Lifesystems Rechargeable Twin-Pack Dual-Palm Hand Warmers With Power Bank Functionality, USB & USB C 2x 5,000 mAh Batteries, 3 Heat Settings, Up To 9 Hours Heat

These are a game changer for anyone who suffers with poor circulation. Mine arrived two days ago and have been everywhere with me. I've just had to recharge them after two days of on/off use so battery life seems really good.I mostly use them on the 1st setting, 2 if my hands are really bad but haven't needed 3 yet. The size is excellent and temperature just right.My only quibble is the annoying rubber thingy that covers the charging USB sockets. It seems like it'll break off easily as similar things in the past have done and it does come out a fair bit.That said I've still given these 5 stars because they've made such a difference. I keep them in my pockets and use them as soon as my hands start going cold. I just wish that women's clothes had more pockets because a lot of my clothing has nowhere to keep these lifesavers.My sister has Raynaud's in her hands and has also ordered a pair on my advice. Buy them, you won't regret it.

I brought 2 sets. 1 for myself which is amazing on a cold easily morning start. Heats quickly to a great temp and battery lasts well, being magnetic to each othet is handy to not loose one.There other set I brought for my son who goes to an outdoor forest nursery, that were the ones who recommended them. Their great for small hands to heat quickly especially when they get cold and wet. Definitely a great addition to his nursery bag.

More plasticky than expected but heat effectively and last a reasonable amount of time.

One of my most highly rated purchases. I have several of these. They charge up easily, last for ages when charged up,- even when left in a freezing camper - and last ages when switched on. I give a couple to my grandkids when they are going to the swimming pool for an early lesson, keep one by my chair to pop under my toes to warm them on a chilly evening, and use them instead of a hot water bottle in my sleeping bag. I also pop them in my Pockets for cold days out and they keep me toasty. Can’t rate them highly enough.

Heats quickly and good range of settings from thawing out frozen mitts to keeping pocket cosy. Battery life is good and large enough to heat hand properly not just tips of fingers like some. Have yet to use battery pack feature but could be useful at a pinch.

I purchased these for hiking/backpacking in the mountains where temperatures can drop quickly on ascent.I honestly didn't expect much out of this considering the price but I'm pleasantly surprised! They heat up quite quick so long as you keep them contained in pockets or gloves, and the fact that they're type C and double as a power bank means no extra weight carrying a dedicated bank and different cables.

Great product very happy.

It's not as powerful as I thought it would be, and it's not value for money, to be honest. The charge speed is a few hours. You can put it in your pocket, but it feels heavy and uncomfortable. I would say put it in your coat/jacket. It's not worth the money, to be honest. You can find cheaper ones.
