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 Alex Romero

Tried twice and neither worked. The first one I ordered only got hot when plugged directly into the wall. I bought the recommended portable charger, but it never exceeded the first setting when plugged in, and even then it didn't get hot. So I thought maybe my first blanket was faulty so I traded it in for another one and even bought a portable charger even bigger/stronger than the one recommended to see if it would help as I REALLY wanted to that this blanket works to bring you a long time. Sons cold soccer games. The second had the exact same issues even when connected to a more powerful charger. It doesn't go beyond the first setting and doesn't heat up at all. I ended up sending a second one back too, and now I'm trying to find another option for cold autumn games.
