XGUO Rechargeable Hand Warmer Reliable Double-Side Heating Pocket Hand Warmers Electric Handwarmers 5200mAh Portable USB PowerBank Best Gift for Lover Family Women Mom Father in Winter (Black)

I bought this thing to prep myself for a visit to New Hampshire in the winter.I live in Georgia where winter is considered a nice 60.It was 12 when I got to New Hampshire and I would have regretted it a lot more if I didn't have this to keep me warm.My best friend told me that I just needed to find someone to keep me warm instead but this was a lot easier to get through TSA.It gets very warm, it's compact. I put it in my jacket pocket and left it on for a good 3 hours without any worries.The battery charger part is nice, but I'll admit I didn't use it as much because I specifically bought it for the heat.Also works really nicely as a heat pad for your muscles if you get lost wandering around the woods looking for a frozen waterfall you saw online so you can go take awesome photos to post on instagram.Just in cast that's a thing you do.

I have Reynaud syndrome. I’ve used disposables in the past. This thing is amazing. Works perfectly and will charge my phone.

This thing is amazing. I was super sceptical and figured I would return it if it sucked. Turns out if gets hot AF!My fingers started to hurt a little and I had to turn it down!I'm literally buying another one right now. I am very impressed.Update: I took it to an outdoor concert last night where it was 25 degrees. I left the unit on high and put it in my chest pocket and it worked so amazingly well and kept me warm!The runtime on high was 4.5 hours before it died. Very happ.

Tried to re-charge this hand warmer/phone charge on multiple occasions without success. Returning it!!!!Don't waste your $$$ on this model. Oh....by the way the model of the unit I ordered is not what I received from the seller.FYI....It does come with a USB cord but not with an actual plug in order to plug it into the electrical socket in a wall to recharge. The USB connector did not go into any of the USB ports on my computer for recharging purposes. So I used a self supplied electrical wall plug that connected to the USB cord (like you would charge your cell phone to an electrical outlet.) and this thing would not charge. The charging light indicator came on as per indicated in the instructions but this thing never charged.By the way the instructions are in extremely small print. You can not read them easily. This is coming from a person with 20/20 vision. Use a magnifying glass to read the instructions.

I've ALWAYS got cold hands-unless I'm hot flashing! LoL.. Anyway this gizmo fixes that.. You can hold it in your hand, pass it back and forth, leave it in your pocket and it warms you up in a flash. I bought several as gifts as well and they're a BIG HIT. Turns out my girlfriend has Renaud's Syndrome (extremely poor circulation) and she put the one I gave her inside one mitten on the drive to work. She sent me pix afterwards and the contrast between the two hands was scary! So she bought another one, but noted that it's difficult to drive to work with both! AHAHA! Don't do it, but buy this Hand Warmer!

These hand warmers have been working great. I run quite a bit and this winter has been pretty rough, especially with getting the hands cold. I turn these hand warmers on low and placing them in my mittens, my hands stay nice and warm. The warmers easily last for my longest runs, 4 hours or more. I have never have had to increase the setting above low and the movement of running doesn’t bother the warmers and they are easily turned off or back on while they are in my mittens, while on the run.

Staggeringly efficient. Heats up within 5 seconds, and lasts as long as you need it to for keeping your hands toasty. Only complaint is that it takes AGES to recharge, making keeping this thing alive tricky. You also can't charge and use at the same time, which I assume is a safety feature, but keep that in mind if you're going to be away from a power source for a long period of time.

Actually works. I have a hand warmer that uses lighter fluid but it wasn't convenient because you have to light up the warmer and couldn't turn on or off. This rechargeable hand warmer does the same thing without the hassle and you can select the heat level. I didn't test using this for recharging cell phone.

Not a bad product it does what it say but it is not a very polished product.My use of it is mainly at my computer. While gaming I get cold hands so I use this product to warm up my hands.This thing get surprisingly hot I'm very happy with that aspect but there are some problemsPros:It can get very hotIt's very quick to get warmThe form is comfortable and smooth in your hands.It last for a decent amount of time if you use it sparingly.Cons:The button is badly placed. You often press it by mistake while holding the thing which changes your heat level.The 3 levels of heat are, barely lukewarm to hot to barely hotter.Nitpick:When you unplug it from a charge the blue light indicator stay on for an overly long time and hides the heating on lightsFor the price still thinks it's an ok product to get but you might want to look at one that has a little more polish.

Bought this for my elderly mother who always has cold hands. Relatively simple to use once you get the hang of it. Three heat settings to take care of everything from slightly cold to frozen paws. Claims to take 2 hours to fully charge but it's probably closer to 4, however that is hardly a deal breaker as it takes quite a while to wear the battery down. Comes with its own drawstring pouch and USB cable. For the price, I've got no complaints!

Good design overall and when it worked, it did the job. Unfortunately mine had some button issues after a couple of weeks in which it would intermittently not turn on, or when it did, not be able to adjust heat levels. The latter is quite important, as there is a very big difference between the first and third heat setting. First is lukewarm and wouldn't go through say a fabric pouch, whereas third is very surprisingly hot to the point where without a pouch its nearly too hot to hold for long periods - in that sense very effective. I chuckle in that these seem like to me badly made battery banks that instead of getting tossed gets made into this. Worthy note that the battery lasts a long time, and it's a much less waste alternative to those disposable packs while being small enough to fit in your pocket.

The first week I used this, it was great. Going out at recess and lunch was now manageable. I liked that it has an on/off switch and 3 heat settings. The lowest heat setting was enough to keep me warm. Then comes week two, today I couldn't get it to turn off as it looks like the button went in at an angle. The device was quite a bit hotter on one side than the other, too hot to touch and I could not get it to turn off. With the button being stuck I had to just leave it on my desk until the charge went out. Unfortunately, I have already ordered another one for my other glove, sure hope I don't have to return this one too.

I purchased two of these hand warmers one for each coat pocket, I use fingerless gloves when I'm out doing photography, so I have the ability to operate the camera controls, I went out yesterday to do some bird photography and try them out, and they worked very well and kept my hands quite warm when they were in my pockets and waiting for some action to photograph, it was 3° Celsius and quite windy and my hands warmed up quite quickly in between each series of pictures I shot, it's much faster to get my hands out of my pocket and onto the camera than pulling mittens off when some action starts, my hands also stayed much warmer using these hand warmers rather than mittens over the fingerless gloves, I'm very happy with my purchase and purchasing two of these was much cheaper than dedicated photography gloves which are ridiculously priced, I also found these warmers quite useful for working in my garage yesterday, I would definitely recommend this product to others.
