10,000 ma battery will work
I bought this to add a little heat to a sleeping bag for a pending fishing trip into the Northwest Territories. I have not used it for that purpose, but I have tested it to see if it should work out.I am satisfied that it will, and that it will be GREATThe picture is of a test in the works.A bit of background. I am testing a 10,000mah battery, borrowed from a VOLT heated vest, and how it will work out.10, 000 ma is, of course, 10A. Remember that Amps(A) multiplied by Volts(V) equals Watts(W). You need to know, as well, that a standard battery pack gives 3.7V at all times. A 10,000mah battery will give 10 amps for one hour (=10,000mah, thus the âhâ in âmahâ). Or it will give 1 amp for 10 hours or any combination that multiplies to 10Ah.At 3.7V that means that the capacity of the battery is 37WA , ie., it will give some combination of amps and hours, always at 3.7V, such that the product of the three is 37.Testing the pad and battery.On low(green) my 10,000mah battery (=37WA as described above) was used up in just under 6 hours. The meter showed total consumption of about 32 WA. Plainly either the battery was not fully charged or it is not efficient to a full 37WA, or a bit of both. On low heat(green) it used about 5.4WA.On a similar test, on high heat(red) it consumes about 9.6WA. So in theory, the battery should be good for about 3.8 hours. I got more like 3.2.The picture is testing on medium(blue). it shows power consumed and time passed. It looks like it is using about 6.8AH. So, ideally, it should be good for 5.4 hours before the battery is fully discharged. More likely, given that this battery is not giving a full 37WA, I expect to get about 4.7 hours. If I get something different, I will amend this reviewIn summary, total capacity should be 37, actually less, maybe 34. Low=5.4, medium=6.8, high=9.6 So some time at low, medium and high at their consumption rates for the time used will work at out so long as the total use does not add up to more than 34My experience is that to have the battery go dead after about 5 hours sleep works out well. The residual heat stays until it is time to get up. YMMV.The pad gives of a warming factor. It is not meant to be a sole source of heat. It just takes the chill off a cold night in a sleeping bag and lets you sleep without any cold effect.I think a 10,000mah battery will be enough. Of course, 20,000mah would be betterI hope this helpsAddendumIâm back. It was cold up north this year. I was glad to have the padThe battery worked but a 20,000ma one would be better in that it could warm the sleeping bag before getting into it then running on lowQuite happy with it after the ideal test for my needs

Heats really well
I was a little hesitant to purchase this heating pad due to the varying reviews, but I’m glad that I did. I’m going to be using this for an upcoming camping trip and want to try to stay as warm as possible, so I tested it with a 10,000 mA portable phone charger to power the pad and it works great. It puts out a good amount of heat, even on medium setting, and I had to turn it off because I started to get hot. The only reasons why I didn’t give this a 5-star review are because 1.) the material used is a bit noisy and crinkly when you move, and 2.) because I’m not fond of the location of connectors being by the head. I think there could be a better location for the connection.

great purchase
This blanket works really well when you lay on it. Keeps your body temperature warm. Order the recommended charger with it. It was well worth the purchase.

Buyer beware
This product didn’t do as I purchased it to. I lived it in and turned it on and nothing. The light blinked a few times and straight off. No heat. I was just camping and the nights were in the 30s so I needed the heat but when there was none I was not happy to say the last. Buyer beware.

It’s great for what it is.
Lets start out by stating the obvious. This is not an electric blanket. Those who want a blanket please don’t buy this. It’s exactly what it’s supposed to be. If you want some warmth between you and whatever you’re sleeping on, this is for you. It’s great. Perfect for a sleeping bag or just by itself. It runs off my battery pack so don’t expect a tremendous heat pumping out, but it does get pretty warm. Inside a sleeping bag it’s great. Battery hides in the pouch and has 3 modes for comfort level. On high it’s a perfect amount of heat to keep you warm. I have mine in my Coleman extra wide bag and it’s currently 38 out and I’m cozy as a field mouse lol. I’m also 6’3 and it covers my whole body most heat it up near my head which is closest to the battery but my lower half is warm as well. Great product so far. I’ll have to see how long it stays on. For what I need it is a great product. It’s better than having a bunch of hand warmers throughout my bag lol.

Great Idea, but bad design
I ordered 2 of these for a camping trip, it was 40 degrees at night We also ordered 32000mah charger. Set the mats to high at 9 pm and crawled in, they didn’t get hot and ran out of power at 3 am and then we froze. Also, the battery pocket on the mat is in a stupid place. Once the battery pack was placed in it. I had to lay on it all night long. They should have the pocket the battery goes in and the button hanging off the side of the mat so you don’t have to lay on it. This would also make it easier to see what temp you have it on and prevent you from accidentally unplugging it or pressing the button and changing the temperature. returning these for sure.

Great for Camping Warmth
I used this heated sleeping pad with a 32000 mAh Rechargeable Battery for a multiple night winter van camping trip where the outside temperature dipped below freezing. The pad was too hot on the high setting, but the low and medium settings were perfect and the battery lasted until about 4:00 am. The bag heats up quickly and was comfortable to lay on all night. I recommend a stronger battery or purchase a backup battery. I’ve only used it for the one camping trip, so I cannot comment on the longevity of the product. All in all, it did the trick!

I use this for winter van camping. Tested this last week with -10C outdoor temperature (Inside temperature was around -2C). This kept me warm on the high setting.My battery setup is a car/agm lead acid battery attached to an inverter. Conventional AC power heat pads draw a lot of power (11 hours on an 85 amp hour battery). With the USB heat pad, I use much less power.This does not get as hot as an AC plug-in heat pad so it’s important to mitigate expectations. I find the usb heat pad works well when paired with other heat sources (ie. down sleeping bag, candles, etc.) for winter camping but may not be warm enough when used solely in winter weather (ie. -10C).I’m 5’4″ and all the heat zones warm my body except for the foot heat zone. I also love the buffalo plain design.

Oh I like that feel of this blanket. I like the weight of it. It is already super warm, without having the heat turned on. I also love the size of it. I have put it in the sleeping bag and oh boy, this made all the difference.

If you are looking for a USB battery operated bed warmer while you are cold or winter camping, look no further! I have been using this all winter when camping out in my yurt. The wife and I fit in one and we put it under our blowup bed or the cot. It eliminates the chill when winter camping. You can also put it on your when your are sitting on a camping chair to stay warm. I use a 10000mah battery pack and it usually last a single night, so I keep a few battery packs on me for multiple day camp trips. I highly recommend this product if you are camping out in the cold!

Very little heat. I can’t imagine buying this and hoping to stay warm while camping.

Nice and soft to the touch but heat is mostly on the edges not everywhere. Helped on cool nights tho
