GUGGHA Rechargeable Hand Warmer Power Bank Portable Charger for Samsung, iPhone Smartphones, Compatible with Most Windows & Android Devices

I bought this hand warmer/power bank/flashlight specifically for the hand warming function due to a medical condition that has my hands freezing most of the time & I needed something that would give me some relief. It works exactly as you would expect. I've not tested the duration of operation as I turn it on for a few minutes at a time to keep my hands warm. It recharges fairly quickly and has a small blue LED that blinks when it is charging and is steady blue when full charged. There is a small red LED that blinks slowly on the low heat setting and fast on the high heat setting. It has a nice substantial weight and is shaped to fit in my hands nicely. The only thing I'd say would be an improvement is there is only one button to activate all functions based on a combination of number of "clicks" and the duration you hold the button. I've mastered it for the low/high and off heat functions the flashlight sequence is still not intuitive to me. The instructions are readable, but were like many small electronic items these days not written by a native English speaker. If you need a great little hand warmer with some bonus features buy this one.

Tested after full charge. Low heat lasted less than 1 hour not 300 Minutes. Could not get high heat to turn on. To bad nice design well made but functionality as a hand warmer is iffy at best.Update. I ordered a new unit to reevaluate. Raise to 3 stars for excellent customer service.

I’m a hospice nurse with forever cold hands, no matter the gloves. Even after I attempt to warm my hands as much as possible, my patients still notice the cold and comment. HOWEVER, this has made a difference! I turn it on and switch it back & forth between my hands and with-in one minute, toasty hands! No more “whoa’s” from sweet or mean elderly patients. Everyone’s happy!It heats up quickly and so far works great! It’s to big to fit into my gloves. But I like the size, it is able to warm my palm and fingers when held in one hand.

Excellent product. I am starting to get arthritis in my fingers and this really helps.2/28/2017 Have to return item, it does not fully charge. I do really like this product so I am going to order a new one.Will give updates if necessary.

Good unit. There is a pink one by the same manufacturer that I like better. Same price. Slightly larger and more powerful. Easier to use, too.

I love my Guggha hand warmer so much, I ordered a 2nd one! I had to have surgery on my “funny bone” this year and it put an end to exercising one arm. Without that circulation my hand is COLD all of the time. Guggha has been a real blessing!

This is amazing!! The soft pouch hand warmers will last longer but will not put out anywhere near the amount of heat this does. I use mine on low heat and it instantly gets warm and keeps me comfortable in the December tree stand. The flashlight is very bright and gets me out of the woods after dark. I have not completely run it out of battery yet, but I am guessing on low heat it will run for 3-4 hours. It works so well, my husband and dad bought one too!

Got this for my wife, she's an esthetician. Cold hands and relaxing facial, just doesn't work. Your hand warmer doses.
