Three heat settings and portable with using a battery pack
Lower back pain is no joke. The doc says regularly heating up the back will help loosen things up. He gave me one of those ice/heat packs, but they're annoying to keep reheating. This little guy just velcros around your waist with three different heat settings. Two different power cables were supplied. One for the power outlet and then another with a USB port. I chose to use the latter, so I can be mobile and do stuff around the house. I used it with a 20,000 mAh battery pack and it worked well. It was easy to use and gets nice and toasty.
