Expert Warns Against 'Electricity Saving' Devices Sold Online
A viral social media post has prompted a warning from a prominent Thai academic regarding fraudulent 'electricity saving' boxes that remain on the market in 2026.
A recent social media inquiry in a popular Thai household advice group has sparked a public warning from Assoc. Prof. Dr. Jessada Denduangboripant, a lecturer at Chula University’s Faculty of Science. The discussion began when a user questioned the efficacy of a device her husband purchased, which was marketed as a tool to reduce electricity bills.
Dr. Jessada expressed disbelief that these so-called 'electricity saving' boxes are still being sold in 2026. According to his assessment and data from the fact-checking platform Cofact, these devices are fraudulent. Despite online advertisements claiming they can reduce electricity consumption by 30% to 90%, they provide no actual savings. Technical inspections of such devices typically reveal only a small capacitor or a single LED light inside, offering no functional benefit to a home's electrical system.
For residents and travelers in Thailand, this serves as a reminder to be cautious of online shopping claims. Beyond the financial loss, experts warn that these devices may pose a fire hazard. As of now, it remains unclear how many of these units are currently circulating in the market or what specific regulatory actions are being taken to curb their sale. Consumers are advised to rely on verified energy-saving methods rather than unproven plug-in gadgets.
