With the Inventum HNK355B heating pad, you can take pleasant warmth with you wherever you sit. Slide the charged battery into the inner cushion's compartment and press and hold the on/off button for 2 seconds; then select your heat setting with short presses. Because there is no cord attached, you can move the cushion just as easily as a regular decorative cushion, from the sofa to your chair or your home office. This way, you have warmth at your fingertips, exactly when you want it.
Why choose the Inventum HNK355B
✓ Fully wireless use: the rechargeable lithium-ion battery is in a storage compartment in the inner cushion, so you are not tied to a power outlet.
✓ Up to 4 hours of warmth per charge: how long the cushion lasts depends on the setting you choose. Charging takes about 3 hours with the included AC adapter.
✓ 3 heat settings with rapid warming: from mild to maximum warmth. If you start on setting 3, the cushion heats up extra quickly for the first 10 minutes.
✓ Size of 45 x 45 cm: comfortable on your back, on your lap, or against your stomach, and beautiful enough to leave on the sofa in between uses.
✓ Soft corduroy cover: the material feels warm against your skin and meets OEKO-TEX Standard 100, which indicates that the fabric has been tested for harmful substances.
✓ Cover washable at 30 °C: remove the cover from the inner cushion and wash it in the washing machine on a wool cycle.
✓ 5 years Inventum warranty: standard with your purchase, for years of carefree use.
Decide for yourself how warm you want to be
Briefly press the on/off button to switch between setting 1 for mild warmth, setting 2 for medium warmth, and setting 3 for maximum warmth. Red LED lights indicate which setting is active. If you use the cushion for hours on end, choose the lowest setting.
Charging and reading the battery status
Connect the AC adapter to the control unit; three white LED lights will flash during charging. If all three are lit continuously, the battery is full. The number of lights indicates how much charge is remaining. Charge the battery in a dry room at normal room temperature and do not cover it while charging.
Safe and automatic shut-off after 90 minutes
Approximately 90 minutes after switching on, the cushion will turn itself off, allowing you to relax without watching the clock. Do you want to continue for longer? Press the on/off button again; after about 5 seconds, the cushion will be on again. The built-in safety system with sensor technology monitors the temperature.
Easy to keep clean
Remove the cover from the inner cushion and wash it at 30 °C on a wool cycle. Keep the heating unit, the control unit, and the battery dry and clean them with a dry, lint-free cloth. Use the cushion again as soon as all parts are completely dry.
