Supercharge your Kalhuohfummi – with our new extra large solar panel


Greetings Changers,

Now that the new app is out, we don’t want you to forget about your little battery at home — so we are releasing our new extra large solar panel to keep Kalhuohfummi fully charged during the next winter months.

Our new panel Maroshi IV can more than triple your energy production from 4 Watts to 13.5, which allows you to charge your Kalhuohfummi in half the time, and works especially well in low sunlight conditions.

This is a limited edition release with only 100 available, so they won’t be around for long!
