Overview

• Verivox and Testberichte.de analyses show mobile units’ yearly electricity costs amount to about one-third of their upfront purchase price.
• After roughly three years of operation, cumulative energy expenses typically equal a unit’s initial purchase cost.
• Acquisition and annual running costs climb with room size, from an average €303 purchase and €109 electricity bill for 15–30 m² spaces to €547 and €172 for areas up to 60 m².
• Most mobile air conditioners carry an EU A-label based on lab tests that fail to capture higher real-world power consumption.
• Consumers are advised to compare annual kWh usage, cooling capacity and EER values instead of relying solely on energy-efficiency labels.
