Portable bottle warmer with monitor / thermal bag for bottle

Portable bottle warmer with temperature monitor / thermos bag for a bottle. Five temperature settings: 38C, 42C, 46C, 50C, and 55C. Works with a USB cable in the car or with a Powerbank. Allows you to take your favorite warm drink anywhere. Universal size (sealed with Velcro). Bought new on Amazon, but didn't get a chance to use it as the child quickly started drinking from a cup. It comes with original packaging and an English user manual. The price is symbolic because we need to clear the cupboard.
