TriPole Hand Warmer 10000mAh Rechargeable Portable Power Bank Reusable Pocket Hand Heater Double-Sided Heating 3 Levels 9Hrs Long Lasting Electric Handwarmer for Outdoor Sports Women Men Winter Gifts

It's a nice pebble-type feel. I charged it up overnight and at 10am switched it on at the lower setting. Ir lasted 8 hours and gave off a nice heat all that time. Instructions are simple. Great dual purpose as you can use it to charge your device if your battery is low. The picture shown orange look but it doesn't change colour. I don't notice much effect from the low setting to the high setting, although it is warmer. The low setting is warm enough. Very happy with it.

I saw this just before a camping trip. I ordered it and am so glad I did. I was camping for 2 nights and the temperature was -1, it was so cold and this saved me keeping my hands warm but also snuggling up with it, it stayed nice and lasted for 8hrs .I had a power pack to recharge for the 2nd night and it charged perfectly.

Seems good enough, not sure about it being 10,000mah but time will tell, gets hot enough! Instructions seem like they were for a different model (model with percentage charge rather than light bars) but easy enough to use.

I use them all the time in the colder months.

This is a good sized hand warmer. It will last about 10 hours on the highest heat. It’s comfy to hold and it’s pretty warm. Obviously it’s not “hot hot” as hand warmers could potentially burn you if they get too hot. The price on Amazon was really good as well

Clear easy to read display. The display shows temperature settings and battery state. Push button operation is simplicity itself.The Tripole Hand Warmer 10000mAh is perfectly shaped to fit the palm of my hand and comes with a fabric pouch. The pouch is essential because the hand warmer gets very hot. Charging time is about 3 hours and run time is long, sorry I haven’t measured it.I was so impressed with my purchase I very quickly ordered a second. Now I can keep both hands warm when I’m out in freezing temperatures photographing wildlife and landscapes.I have no hesitation in recommending this product 100%.

Very please with it, battery last longtime, not taking too long to recharge, happy customer thank you

"Ok guy's I have to add to my original review. The heat is great when it works but it is incredibly inconsistent, Such a shame. The first week was great but it has been erraticsince then. For the money I would now have to say buy something else." Heats up quickly lasts ages. Only upgrade I would suggest is the shape could be more hand shape friendly. Still delighted with the purchase.
