MANTUOLE Heated Sleeping Bag 5pcs Multi USB power support Heating Pads,Operated with Battery Power Bank or other USB Power Supplies, Portable Compact Bag, Mummy Style.

Have not used it yet, but did try the usb port on a battery bank and it heats up quite well. Let's just say if you were camping in the fall or winter you would probably be thankful for the heat. It's not super heated, but it will help in the cold. Overall a large sleeping bag. I'm 5'10" and it should fit me well.

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!

Perfect for cold days

UPDATE 08-11-21: first my apologies to the seller for not contacting you first even though I was past the warranty date. You have proven that you Truly care about your customers and stand by you product 100%Thank Yourating changed from 1 to 5 starsBought this for a Christmas present for my wife and just this last weekend was able to get out and camp.over all the bag is light weight and seems durable. the down fall of this product is the HUGE power draw for staying warm. we bought this for pack back camping and thought it would be nice as my wife gets cold easily. In one night we killed a 100hr Cell phone charger and a 1000 Hr. power bank. there was also no heat to the lower two zones. now maybe we got a defective bag and there is a short in it or maybe it is just a bad design and purchasing this one should be avoided. being to late to return for refund we might just open it up and see what the inside story is

My 18yr old 6'2 son decided to go camping last min and I ordered this the afternoon before he was leaving. It arrived with a couple hours to spare and he said he was very comfortable and loved the heating feature.
