Yes it does yes it does all you have to do is hold it down and then the green circle will turn on or something

Did not warm up at all... That was the whole point of me buying this :( I am very disappointed

Tried and tried really wanted this to work ! Charged it and it would NOT work! Charged the phone but would NOT get hot ! DANG!

It doesn't work! It took forever to get to me, and I go to use it, and it won't charge! I'm so sad.....the reviews were good, but not worth the headache, I'm taking it back.

[This review was collected as part of a promotion.] The pocketjuice hybrid heat works great. It heats up fast and easy to use. I like that it has three different setting for the heat and lasts about 3 hours. It charges your phone fast also.

[This review was collected as part of a promotion.] I got the Pocketjuice Hybrid Heat and rechargeable Pocket hand warmer and charger. Its heavy but fits in hands well. I charged it by outlet because the instructions were bit vague but to those who read my review note its better to charge it by PC then it works great. It doesnt take long to charge up. You have 3 settings of temps to change it to and each setting shows different color light so you know what setting is on. It takes about a minute to start feeling the heat but once its on it really works great. Be carful with it is there is a Lithium battery inside it. It comes with hand warner and short usb plugin and directions. It helps a lot to warm up your hands.

[This review was collected as part of a promotion.] Pocketjuice is just what I need. I can take it with me wherever I go and it warms my hands at the same time. It really helps with the pain in my hands. The charge is fast and it lasts for a suitable time. I'm loving this cool gadget!

[This review was collected as part of a promotion.] Charge faster, warm faster, but I think is not enough for very cold days, the battery is durable and u Can charge ur phone while keep warm the hands.
