Review on Stay Warm and Cozy Everywhere: PerfectPrime HP0810 Soft Fleece Portable QC2.0/3.0 USB Power Heating Throw with Temperature Setting Controller for Winter Traveling, Camping, Hiking, or Wheelchair Use by Edward Freeland

I have a small camper that I use twice a year for cold weather camping. Even if you're not in a tent, the cold weather is COLD. One day I woke up with a headache because my head was the only thing that wasn't under the covers. If I ONLY had the energy (when boondocking you unplugged) or something to warm myself up enough to sleep comfortably again. The Revain QC 3.0 USB power adapter is $25, so I took a chance and tried this hot shot. I have read the specs and reviews and CLEARLY UNDERSTAND that the true size of the heater was smaller than the throw. It would be a deal breaker if I had to throw as the only source of warmth for comfort, but I just need something I can turn on and banish the 2am chill so I can get back to sleep. I tested the litter with a regular battery pack and found ALL REVIEWS claiming that this doesn't work because they use regular battery packs which prevent them from getting the heat to the second and third stages. I then tried the USB QC 3.0 battery and it was uncomfortably hot. When used in cold environments, levels 1 and 2 were preferred, offering about the same comfort as a rubber bladder heater with heated water. t require FIRE or grids. The QC 3.0 device can be charged using solar power, but it took a few days before this became necessary. This boosted roll is a nice bonus. I recommend it.
