A recent DAIRU USB Charger Alert This has raised alarms among consumers and consumer protection authorities in Chile, and the case is beginning to be scrutinized in other markets as well, including Europe, due to its potential impact on domestic electrical safetyThe problem centers on a technical fault that could cause dangerous overheating of these devices.
The official warning, issued by the National Consumer Service (Sernac), affects two specific models of USB chargers from the DAIRU brand sold exclusively in Sodimac stores. The agency has specified that the affected batch It does not meet the required electrical certification standards., which opens the door to malfunctions with a potential risk of fire.
Origin of the alert regarding DAIRU USB chargers
The case stems from a specific safety alert regarding DAIRU USB chargers which went on sale between November 2025 and February 2026 in Chile. According to the information provided, these are products of Chinese origin which were distributed under the DAIRU brand in the DIY and home furnishings channel.
The company responsible publicly acknowledged that it was detected a technical anomaly in the certification processThis means that the affected batch did not meet the minimum required electrical safety standards. This non-compliance is what prompted Sernac's reaction and the subsequent withdrawal of the chargers from the market.
From a consumer protection perspective, the alert highlights the importance of USB chargers and adapters comply with homologation standardsespecially in markets with strict regulations such as the European Union. Although the issue has been detected in Chile, similar problems could be monitored by European authorities if identical or equivalent products are found.
The official statement emphasizes that the lack of security validation is not a mere bureaucratic detail, but rather This implies a real risk of failure during normal use of the product.especially when chargers remain connected for hours or are used with high energy demand devices such as tablets or fast-charging mobile phones.
DAIRU USB charger models involved
The alert regarding DAIRU USB chargers does not refer to the entire range of the brand, but to Two very specific models that have been identified by their reference and SKUThis detail is key so that consumers can check at home if they have one of these products plugged into a power strip or bedside table.

- DAIRU DR-CUSBAC-25W (SKU 7796447), a higher power model, geared towards fast charging up to 25W.
According to the data provided, The total number of affected units amounts to 19.218 chargersFrom that volume, 13.962 units were still in stock at the time of the alert and were subject to preventive withdrawal, 2.332 were still in the distribution chain y 2.924 were already in the hands of consumers final.
These chargers were sold exclusively through Sodimac stores across November 2025 and February 2026This information is relevant both for Chilean users and for those who, from Spain or the rest of Europe, may have acquired these products during trips, international online purchases or orders from third parties.

Risks: overheating, ignition and possible fire
The core of the DAIRU USB charger alert is the risk of overheating of the device during operationAccording to information released by Sernac, the detected anomaly could lead to an excessive increase in the charger's internal temperature, which, in certain scenarios, could result in component inflammation and fire.
Among the dangers described, the following stand out: risk of short circuit and fire of the chargerespecially if used in unfavorable conditions: overloaded sockets, power strips without ventilation, proximity to combustible materials such as paper, textiles or wooden furniture, or uninterrupted use connected to the mains.
This type of incident not only threatens the charging device itself, but can also damage your mobile phone, tablet, or other connected devices and even cause a house fire with much more serious consequences. Therefore, although no mass casualty incidents have been reported at the time of the alert, authorities emphasize that the Prevention is a priority in the face of any sign of electrical failure.
The company involved has indicated that the batch in question It did not successfully pass the tests included in its internal certification processThis lack of technical validation would explain why the charger might behave erratically under certain normal usage conditions, such as fluctuating currents or intensive loads.
From a comparative perspective, in European countries the safety regulations for low-voltage electrical equipment require that The chargers have specific certifications and CE markingIn addition to passing thermal, insulation, and resistance tests, situations like this serve as a reminder of the need for Check official seals and buy from reliable channels, both in Spain and in any other territory.
Recommendations for affected consumers
