KingCamp LunaRest Heated Sleeping Bag Liner

I really liked this heating pad, I would have loved this thing when I was younger and camped all the time in a tent.

I used it with a Audew jump box that has USB outputs for power and it seemed to heat up fine. Keep in mind it’s made to be in an insulated sleeping bag, if it’s in the open air it won’t feel like it gets that hot and it won’t in open air. Laying on it or in a sleeping bag you will notice the heat.

Flannel material feels like it has a lot of polyester in it, it’s not a cotton flannel. The back side is a slipperier material with little dots that look a lot more grippy than they are.

Im glad this heating pad exists. It’s like a low power electric blanket for your sleeping bag. Just gotta have a power bank to run it.

I thought initially this was a bit expensive considering there is no power bank included. I then realized in general heated blankets are pretty expensive, and this is basically a more durable/specialized heated blanket. So I think the price is fine.

It doesn't get too warm, but that's to be expected as a power bank is only giving off 15-20 watts. You can't really change physics. Also note a 10000 mah power bank is about 38 Watt hours. If your bank's efficiency is 70%, you should expect a bit less than 2 hours on high. ((38*.7)/15).

The actual feel of it is ok. Nothing feels "nice" on skin, but this isn't really designed for direct contact anyways so it doesn't really matter

My only real complaint is I don't like it's input is USB A. I know a lot of power banks have USB A, though I really try to make everything have USB C.

Overall it works, it's light, the price is decent so I think 5 stars is reserved.

I tested this out today to see how long it would run on one of my 10,000mAh battery packs. On high, it ran for just over 2 hours. This will pair well with my insulated sleeping pad and 20 degree down bag. I initially thought this was an actual sleeping bag style bag but it's a sleeping pad topper. It has elastic on each corner to hold it in place on the sleeping pad as well as some non slip traction dots on the bottom to help keep it from moving around. There is a small pocket that strores the connected usb cord and all you have to do is plug up your power bank and press the power button. There are 3 different heat settings as well as 3 different timer settings, 30 min, 60 min, and 120 min. It is a little rough feeling but not terrible and depending on how you use it you probably won't be sleeping directly on it. I will put it on my pad and put my down bag on top of it. On high, I could really feel the heat. I've used similar usb heating products and this one is comparable to all of the others I have used. I had no problem getting it back into the bag by folding it and rolling tightly but not excessively tight like some products. My bag isn't the warmest so I'm hoping this will extend my cold weather camping season a little longer. I will probably bring 2 power banks for each night I intend to need the extra warmth.

I couldn't wait for a camping trip to try this baby out so I used it instead of my heated mattress pad to take the Fall chill off my bed. I thought at first that the power cords had been left out of the package but soon discovered them in a little pocket where they can be stored. Of course I could have learned that faster by reading the directions, but what's the fun in that ? When I finally decided directions might be a good idea, I read that the warmer runs on 5 or 9 volt power banks. Thanks to Alexa I learned that phone chargers are 5 volt. Whew! I plugged it in, turned it to high and waited for the warmth. It took a little while for it to warm up (the directions explained that this would maybe happen on the initial use) but once it did warm up it provided a nice gentle heat which would be perfect for a sleeping bag. I ordered the warmer for my other half (Better Half?? Nah!) to take on his multi day/week ATV camping adventures. The warmer compacts fairly well and has a small duffle bag to store it in. It wont take up too much valuable equipment space. The fabric is sturdy but soft and has anti slip bumps on the underside plus straps which should keep it in place on the sleeping bag. It looks as though the fabric may be water resistant although the warmer is machine washable. Yay!!!!! Note... the fine print says that the warmer should not be in direct contact with skin so it goes under the sleeping bag. ( Or in my home trial under the comforter.) Speaking of the fine print... some of the directions are written in very small font. My old eyes couldn't read parts of them, so I just took a photo with my phone and enlarged them right up. Problem solved. There may be an online instruction manual but I didn't really need it. The only slight negative to the sleeping bag warmer is that it had a bit of that new equipment odor when I opened it up. Since it's machine washable that's no biggie. Now the next step is to send the sleeping bag warmer and the hubby off on an ATV camping adventure. I guess I will let him wait until Spring. Or I will send him to Florida. One or the other or both.
