You can use giimmö plugged in permanently, but please follow these instructions to get the best life from giimmö;
If using giimmö nightly, we recommend that every 4-6 weeks you allow giimmö to completely drain his battery. This is when he lights up only in red. Then charge for between 18-24 hours with giimmö in the OFF position.
This will give giimmö’s battery a full top up.
