I have spent many hours pondering the easiest way to insulate my mini van when camping. Spray foam/crack seal between panels, cardboard + reflectix to insulate windows, large heavy curtain to divide the front and back. Lots of work, even thinking cheap.Discussed this plan with my father. He suggested instead of heating the area you rest in, heat the bed you are using. Suggested a heated sleeping bag and says they take a nearly negligible amount of power, and combined with natural body heat, Low setting should be more than enough for any night here in the Pacific NW. Completely true.I placed a flat, cheap, ~$9 power bank in the zipper pocket for one night. The bank was at about half power in the morning. Then I tested, on low, with the extension USB provided (thank you!), on a 500w power bank. I maybe used up 5-10% capacity overnight, and was quite comfortable, not overheated at all. No freezing-cold face in the morning like I have dealt with for many years before while camping."Did you have your face covered with the hood?" you ask? Nope. The bag + natural body heat made the van warmer overall and was actually noticeable in the morning when I got up.This thing is so decent, I've used it about a dozen times in my bedroom just so I can leave a window wide open to get some crisp fresh air in the room. Opening up the zipper and just using it as a blanket is pretty nice if you need to trim the heat.I'm pretty happy. Reasonable price, performs as described.Thank you for this product!

Without the battery, this is a 55deg bag. Fine for summer or late spring/early fall. The battery will get you another 10-15 degs, so it gets you in the 40s.I bought it to store in my Jeep, for unplanned overnight situations. Tested it and the weather got to 35 or so, I was cold (but would have survived) until I threw a blanket on top. Which was actually my plan all along. Have a light bag and extend the range with a blanket or two. That way you aren't shifting gear based on the season. You just combine it. Layers.Even with the battery heat, this is not a cold weather bag. However, inside ANOTHER bag or under a car blanket, it would get you way below freezing.You will want a 15000mah battery per night. Factor that in to your plans.

We ordered the first sleeping bag and it did not come with the 6 foot usb extension cable that the product says it does come with. We ordered a second sleeping bag just to make sure and the second sleeping bag also did not come with the 6 foot extension cable.

I love my sleeping bag. I went camping and I was toasty and warm in it. I had to turn it off through the middle of the night and i still stayed warm.

The heat works great. It seems to heat fairly even, more or less. The zipper is terrible. It's not difficult at all to zip it up from the outside, but practically takes an act of God to get it fully zipped from the inside. Also, the power/heat setting button really needs a hard cover or long holds to change setting. The button is too easily dressed during sleep, which changes the heat setting. Both my youngest child and myself hit ours in our sleep, causing his to drain the battery pack and leave him freezing in the morning, and mine to wake me up in the middle of the night burning up, with the heat too high. There needs to be a way to lock the heat setting to prevent accidentally changing it.

Doesn't hold warm as well as it should.The heating spots are very miscellaneous and random how the heat is dispersed throughout the sleeping bag. The zippers are low quality overall, 5/10 sleeping bag.Definitely not made for low temperatures or legitimate camping.
