Mains or battery powered: which garlands consume the most electricity?

Anyone who already has battery-operated fairy lights at home: in the long term, they are of course cheaper and more durable, because rechargeable batteries are used instead of disposable batteries. According to TÜV Süd, rechargeable batteries can be recharged 500 to 1000 times and thus replace a large number of disposable models.

You may need to invest more in batteries first. “However, considering that rechargeable batteries can last between five and ten years, in most cases a significant amount of money can be saved compared to normal batteries,” explains Florian Hockel.
