Penny offers €4.99 foldable hand fan as budget cooling solution in Germany

The German Technical Inspection Association (TÜV) has issued safety and efficiency recommendations for mobile air‑conditioning units. It advises consumers to match the unit’s capacity to room size, use a fixed wall socket, keep the exhaust hose short and straight, and ensure the device bears the CE mark or GS safety label. Regular maintenance of filters and condensate tanks is also emphasized.

At the same time, discount retailer Penny will start selling a compact, fold‑able hand‑held fan for €4.99 from 9 July 2026. The Vivess fan features five speed settings, a USB‑C charging cable, and a collapsible design for easy transport, targeting commuters and outdoor shoppers seeking an inexpensive way to stay cool during heat waves.
