Mummy Sleeping Bag with Composite Fiber Heating Plate, Compression Sack for 3-4 Season Lightweight, Water Resistant & Warm for Camping, Hiking, Traveling and Outdoors（Power Bank NOT Included）

I Love This Sleeping Bag! I did not purchase it for traditional purposes, I have severe anemia and require a level of heat that drives everyone else nuts! I have found the perfect Portable solution for me and anyone else who suffers with a cold sensitive disorder! I’ve spent a ton of money on heated blankets and throws that burn out quickly but not anymore! I will never buy another blanket. This is an Awesome invention!! Well worth the money! A must have for chemo patients as well!

The positives and reason for still giving 4 stars:-Very lightweight (not including YOUR powerbank, of course)-Compressible bag is a nice touch-Heating elements seemed (see additional comments below) they would keep you warm-2 drawstrings would have been (see additional comments below) REALLY nice; one for around your face and one for around your neck/shoulders to help retain heatCons and why I returned it:-Too short: I'm 6'3" (and average weight, but inconsequential to the fit in my case) and the face opening was at my neck; I'd need another foot in length on this bag as I don't care for my feet to feel bound up while I'm trying to sleep-Wiring defect: Likely just a fluke, and if this had been the only issue I would have exchanged it for another. Once connected to my powerbank, moving the USB wire just the slightest would briefly disconnect the power, which shuts off the heating element until you manually start it again, regardless of how brief the disconnect.

Comfy and warm

This is amazing. It is a Father's day gift for my husband. I might just have to give it to him early because I am so excited to go camping and use it.

The product works great but their is no automatic shut off and it drains the power bank quick, I have a really good power bank and it killed it in one night, very warm and comfy

I purchased this sleeping bag and the premise of being able to comfortably sleep outside on a 35 degrees at night. When I received the bag I was a little concerned to find only three little heating elements throughout the bag. I was not sure this would be enough to keep me warm all night. I first had some confusion of turning this on, however, I learned by pressing the power button on for about 3 seconds it will activate it. Depending on what color of the light is the temperature that you get from the bag. Red is the warmest so I figured I would go with that. I found the bag just big enough for me. I am 5’ 11” 240 lbs. When you add in all of my clothes I found it just big enough to be able to sleep. When I finally used it I found the heating element was inadequate for my needs. Yes, I could feel the pads warmth however, it was not enough to actually make a difference inside of the bag . This was a great idea however, I did not do the job. I would look elsewhere if a heated bag is what you had in mind. Also, this drained alot more battery what the product description indicated.

Only one area heat up for me little bit. On a big charger to. Restart & change more then do update on it .

The sleeping bag works only on certain portable batteries. It gets Luke warm not hot at all.
