Some evenings the heating just isn't enough. GrumpyHeat puts 3 heating panels across your back and core, powered by a power bank in your pocket. You stay warm from the sofa to the kitchen, with no cable trailing behind you.
Why you'll love it
- Three heated panels – warmth where it matters most: across your back and core.
- Heat that stays in – the heating element sits between a velvety outer shell and a thick sherpa lining that traps warmth.
- Cord-free comfort – runs from any standard 5V USB power bank kept in the pocket, so you can move around the house freely.
- Adjustable warmth – choose your heat level with a simple press of the button.
- Everyday cozy – hood, tie belt, deep front pockets and fluffy cuffs.
How it works
- Connect the cable to your power bank and place it in the pocket.
- Hold the button to switch on.
- Press to cycle through heat levels.
