Chinese brand directories identify Ningbo Lengon Electrical Appliance Co., Ltd. as an operating company in Cixi, Ningbo, with a registered establishment date of November 19, 2002 [2]. Other industry sources trace the company’s predecessor back to the 1990s, while some brand profiles suggest roots as early as 1985. These dates refer to different stages of business development rather than a single legal entity and should not be treated as a definitive founding date [2].

The brand’s history is closely linked to Cixi and Ningbo, which are major production centers for household electrical accessories in China. Industry coverage describes the company as originating from a predecessor known as Cixi Brothers Electrical Appliance Factory before becoming a specialized manufacturer of electrical sockets, converters, and wall switches [1]. Manufacturing operations have been associated with Guanghaiwei Town in Cixi, an area with a high concentration of electrical product manufacturers [1]. By the 2020s, LENGON had expanded its portfolio beyond traditional extension cords to include a wide array of power management solutions.

LENGON’s product range is divided into several distinct categories relevant to both consumer and commercial users.

Power strips and extension boards

This category is most strongly associated with the brand. Products include multi-outlet power strips, extension boards, individually switched power strips, USB power strips, compact mini strips, desktop power strips, travel-oriented solutions, and surge protection devices. Newer models often feature individual switches that allow separate outlets to be controlled independently. Current marketplace listings in the Philippines show LENGON power strips equipped with independent controls and multiple USB connections [3].

Electrical sockets

The brand produces various forms of electrical sockets, including wall sockets, desktop sockets, pop-up sockets, clamp-mounted sockets, recessed sockets, multi-function sockets, and USB-equipped sockets. The company portfolio includes pop-up desktop sockets, table-clamp sockets, PDU products, and smart sockets [4].

PDU products

Power Distribution Units (PDUs) are designed for workstations, computer equipment, networking environments, server rack installations, industrial applications, and commercial setups. Listings in the Philippines feature LENGON PDU products with multiple outlets, individual controls, and USB charging functionality.

USB and charging products

Modern LENGON products increasingly incorporate USB charging capabilities, reflecting a shift from traditional extension cords toward multifunctional power management. Depending on the model, features may include USB-A ports, USB-C/Type-C ports, integrated charging outlets, USB-equipped extension boards, and desktop charging sockets.

Smart electrical products

According to company information, the product family extends to smart sockets and connected electrical products, positioning the brand within the broader smart home and electrical accessories market [4].

LENGON’s design approach combines power distribution with convenience and space efficiency. Current products include desktop-mounted designs, clip-on power strips, pop-up sockets, recessed kitchen sockets, compact multi-outlet units, individually controlled outlets, and USB-equipped power distribution systems. For example, recessed kitchen sockets available in the Philippines are designed to sit inside countertops or cabinets, providing concealed outlets while saving workspace [3]. This approach treats the electrical outlet as an integrated part of the furniture or workspace environment rather than a standalone utility.

LENGON operates its own manufacturing facilities and integrates R&D, production, sales, and service. Company profiles state that the factory follows ISO 9001:2015 quality management guidelines [4]. Products have been associated with certifications and standards including SAA, RoHS, CE, EMC, and LVD, with testing conducted by laboratories such as SGS, TÜV, and Intertek [4].

It is important to note that certification is product-specific and model-specific. Not every LENGON product carries every certification, and buyers should verify compliance for specific items.

China

In China, the brand is marketed under the name 良工 as a specialist in electrical connection and power distribution products. Industry coverage highlights an emphasis on quality, innovation, and service, specifically positioning the company around safer electrical sockets and power strips [1]. The domestic portfolio is considerably broader than what is typically found on international marketplaces.

International markets

LENGON maintains an international presence, though it does not possess the global recognition of brands like Schneider Electric, Legrand, Belkin, or Anker. Company profiles indicate sales in markets including the United Kingdom, Germany, France, Australia, Spain, Italy, South Africa, Russia, and Argentina [4].

In Southeast Asia, particularly in the Philippines, LENGON products are widely available through online marketplaces. Current Philippine listings include desktop power strips, USB power strips, PDUs, portable sockets, and other electrical accessories.

LENGON occupies the consumer-to-commercial electrical accessories segment. Its positioning represents a transition from traditional electrical hardware to modern multifunctional power management. Rather than competing solely as a premium electronics brand, LENGON emphasizes practicality, multiple outlets, space-saving designs, independent switches, USB charging, flexible installation, and accessible pricing. This strategy is evident in Philippine listings, where products range from affordable multifunctional sockets to specialized PDU and desktop installations [3].

LENGON is an established electrical products manufacturer with a documented corporate and manufacturing presence in China, distinguishing it from generic marketplace labels [4]. For power strips, sockets, or desktop power distribution products, it is considered a legitimate brand for evaluation.

However, safety and suitability depend on the specific model rather than the brand name alone. Buyers in the Philippines should verify the following specifications for any imported electrical product:

• Rated voltage
• Maximum current and wattage
• Plug type compatibility
• Grounding and overload protection
• Surge protection capabilities
• Child safety features
• USB/USB-C output specifications
• Local certification requirements

Competitors vary by product category. For standard power strips and sockets, LENGON overlaps with brands such as OMNI, Huntkey, Philips, Schneider Electric, and Legrand. In the USB charging and consumer electronics space, it competes with Belkin, Anker, and UGREEN, although these companies maintain different brand positionings. LENGON’s primary differentiation lies in its combination of electrical installation products, power strips, and specialized desktop, recessed, and PDU designs.

There are unrelated entities using the name “Lengon” that should not be confused with the electrical brand:

• Lengon Valves Company: A separate company based in Xiamen, China, involved in steel pipes, flanges, and industrial valves [5].
• LENGON Trademark (US): A U.S. trademark registration covering electrical products such as batteries, chargers, and computer peripherals lists Xuri Zhu as the owner. This record indicates that not all products bearing the name “LENGON” belong to the same organization [6].
