How it works
All WAHRM products work the same way
No heater and no cable to the socket. Fine carbon fibres in the lining. You click the powerbank supplied into the inside pocket, press the button, and within about a minute you feel warmth.
Click in the powerbank
The powerbank sits in an inside pocket. The same 5 volts as your phone charger.
Press the button
One button on the chest, three heat settings. A short press switches between them.
Just wear it
Under your coat, on the sofa or on the bike. Take the powerbank out and it goes in the washing machine at 30 degrees.
The Heat Network
The heating is not in a few spots, but in a fine network of carbon fibres running through the lining.
No hot spots
The network spreads the heat across several zones instead of along separate wires.
Three heat settings
You choose how warm it gets. The exact temperatures are on every product page.
Runs on 5 volts
Low voltage, with automatic protection against overheating. CE marked.

Most asked questions
Which product suits me?
That depends on where you feel the cold first. If you mainly feel it in your upper body, a bodywarmer or hoodie is the most chosen option. Cold neck and hands: a heated scarf. Cold feet: slippers.
Find your WAHRM and answer three short questions, and you'll know within a minute.
Is WAHRM heated clothing safe?
The heating runs on 5 volts, the same voltage as your phone charger, and switches off automatically if the temperature gets too high. Use the powerbank supplied, remove it before washing, and check the garment and the connector before use.
The products for which this is legally required carry a CE marking. This means the manufacturer declares that the product meets the applicable European product requirements.
How does WAHRM heated clothing work?
Connect the powerbank supplied to the connector in the garment and switch the heating on with the control button. A short press moves between the heat settings.
The exact controls, temperatures and running time differ per product. Always check the product page and the manual supplied.
Can heated clothing help me save energy?
Heated clothing can give you personal warmth without having to make the whole room warmer straight away. If that leads you to actually turn the thermostat down, it can reduce the energy you use for space heating.
The actual saving differs per home, heating system, insulation, hours of use, energy price and chosen thermostat setting. Wearing heated clothing therefore does not automatically produce a fixed saving, as a percentage or an amount.
How do I wash my heated clothing?
Always remove the powerbank before washing and follow the care label of the specific garment. Only machine wash the item when the label allows it.
Only use the garment again once it is completely dry. Do not tumble dry it and do not iron it where the care label rules that out.
