Personal Mini Cooler

The charging block only works intermittently. The on/off button on the side of the charging block seems to have no effect. If I tap the charging block it sometimes will turn on or off. When charging it will charge for a minute or two then stop until I move the charging block or disconnect and reconnect the cables.

Don't like having to carry the charger around with the device , it makes it heavy, and the cooling system can gets hot very quickly

I bought this product because it uses thermoelectric cooling and I was curious to see how well it worked. I was very pleasantly surprised. This device gets ice cold, and it does it fast. It takes just seconds to get to what feels like as cold as ice.

It is an ideal cold pack/ice pack replacement. It is light, and small enough to easily carry around where needed. I need to ice down my knees during the breaks when playing tennis. Having an ice pack available on the court has always been a struggle; but with this product I can literally have an ice cold knee cooler whenever and wherever I need one. I really like the product and I give it 5 stars.

I just purchased a second unit. My first one was a gift and didnt come with a power pack so I used it in the house while plugged into my phones wall charger via a USB cord. Im a avid gardener living in Central Texas where the summers are sweltering. Last summer I would garden in the heat as long as I could stand it then go in the house, collapse into my recliner and place the mini cooler on my wrist, my jugular, the back of my neckanyplace where blood vessels ran close to the skin.all the places I used to place an ice pack. The mini cooler cooled me off quickly just as if I was using an ice pack but it doesnt drip water down my neck and make a mess the way an ice pack does. It gets super cold in a matter of seconds and stays cold as long as its attached to a power sourcewhich for me was forever since I was plugged into my houses electricity via my phone charger.

One time I was using it on my wrist when I realized it wasnt cold any longer; I couldnt feel it cooling my wrist. I pulled the device off my wrist, touched the cooling plate and it was ICE cold. At that point I realized my wrist was numb. It had been on the cooling plate so long Id lost all sensation on the surface of my skin. THAT is a good cooling device!!! Now with the power pack, I anticipate my mini cooler will go with me anytime I have to be outside for an extended period during the oppressive Texas summer. It has a forever place in my life. Great device! Definitely 5 Stars.

I am very happy with this product. It really works well. I like that it is small enough to take everywhere with me and in seconds it works just like an ice pack. I am also able to get over 3 and a half hours of use from the included powerbank.

The mounting strap makes it easy to mount it anywhere where I have muscle or joint pain after excercise. I am happy that I made the purchase. I give it 5 stars.
