FOXSUR’s publicly available corporate history is somewhat fragmented because several company/brand websites have existed under the FOXSUR name. The current Dongguan FOXSUR website says the business developed from 2015, while another FOXSUR corporate/product site says its operation started in 2016. The company’s own 2021 anniversary article describes 2015 as the beginning of FOXSUR’s development and calls 2021 its sixth anniversary.

According to the company’s 2021 account, FOXSUR initially concentrated heavily on battery chargers for foreign trade and subsequently expanded its international business. By 2020, the company described itself as being in its third year of independently developing and producing chargers for foreign markets.

A 2024 FOXSUR product announcement stated that the company had been researching chargers for approximately nine years, consistent with the company’s stated 2015 origins.

Simplified Timeline

• 2015: FOXSUR’s current corporate history places the beginning of the brand’s development in this year.
• 2016: A separate FOXSUR company/product site identifies 2016 as its starting year.
• 2017–2020: Development increasingly focused on battery chargers for international/foreign-trade markets. The company expanded its product-development and manufacturing capabilities.
• 2021: FOXSUR celebrated its sixth anniversary. The company reported serving more than 500 cross-border enterprise customers and introduced its corporate mascot, “Charge Bro.”
• 2025–2026: The company continued exhibiting and launching products internationally, including appearances at the Canton Fair and automotive-related exhibitions. Its current website lists an expanded portfolio beyond chargers, including diagnostic scanners, jump starters and inverters.

Although FOXSUR is commonly recognized as a battery-charger brand, its current portfolio is broader. This makes FOXSUR better described as an automotive electrical-maintenance equipment brand rather than simply a battery-charger manufacturer. The official product categories include:

1. 12V/24V battery chargers
2. 12V/24V battery testers
3. Car jump starters
4. OBD2 diagnostic scanners
5. Power inverters 3

Battery Chargers

Battery chargers are the heart of the FOXSUR product line. The range includes relatively small maintenance chargers as well as high-current chargers intended for larger automotive and commercial batteries. Examples listed by the company include 6V/12V 1.5A, 12V 2A, 12V 5A, 12V 6A, 12V 7A, 12V/24V 8A, 12V/24V 10A, 12V/24V 20A, and 12V/24V 25A chargers.

Depending on the charger, FOXSUR supports various battery technologies, including:

• Lead-acid
• AGM
• GEL
• WET
• SLA
• EFB
• LiFePO4

Some newer models are explicitly designed to support both traditional lead-acid batteries and LiFePO4 batteries.

Smart Charging Technology

A major part of FOXSUR’s product positioning is automatic/smart charging. Many models use multi-stage charging algorithms. For example, the company’s current product catalog includes chargers advertised as 7-stage, 8-stage and 10-stage chargers.

The general concept is that instead of supplying a fixed charging current continuously, the charger monitors the battery and changes its charging behavior through different stages. Typical functions can include:

• Battery diagnosis
• Initial charging
• Bulk charging
• Absorption
• Maintenance/float charging
• Pulse/repair functions
• Automatic voltage/current adjustment

However, the exact charging algorithm varies by model.

Battery Repair and Desulfation

One of FOXSUR’s most visible features is its “Repair” or pulse-repair mode. Many of its chargers advertise functions intended to help recover batteries suffering from sulfation or prolonged undercharging. The company’s catalog repeatedly uses terms such as “pulse repair,” “intelligent repair,” and “desulfator.”

This distinguishes its chargers from very basic transformer-style battery chargers. However, “repair” should not be interpreted as being able to restore a physically damaged or genuinely failed battery. Battery desulfation technology has practical limitations.

Battery Testers

FOXSUR also produces dedicated battery analyzers/testers. These devices can provide information such as:

• Battery voltage
• Internal resistance
• CCA-related measurements
• Battery condition
• Charging/starting-system information, depending on model

Its catalog includes 12V/24V testers intended for applications ranging from cars and motorcycles to trucks, SUVs and boats. 4 This creates a product ecosystem: test battery → charge battery → maintain/repair battery → diagnose vehicle electrical problems.

Jump Starters

FOXSUR has expanded into portable car jump starters. Some models combine several functions into one portable unit, including:

• 12V jump starting
• Portable power supply
• LED/emergency lighting
• Tire inflation
• Digital tire-pressure display

The company’s current catalog includes multifunctional jump starters with integrated air compressors and emergency power functions. 5 This moves FOXSUR into the consumer roadside-emergency equipment market.

OBD2 Diagnostic Equipment

Another newer direction is automotive diagnostics. FOXSUR’s current catalog includes OBD2 scanners such as its V529 and V530 products. These are designed to read vehicle diagnostic trouble codes and provide basic engine/OBD diagnostic functionality. 6

Rather than being exclusively a charging brand, FOXSUR is gradually positioning itself as a broader DIY automotive-tool brand.

Power Inverters

FOXSUR also sells DC-to-AC power inverters. For example, its current catalog includes a 100W automotive inverter designed to convert 12V DC to 230V AC, depending on the model and market. 7 Older/current company information also mentions both pure sine-wave and modified-sine-wave inverter products.

According to the current FOXSUR corporate website, Dongguan Foxsur Electronic Equipment Co., Ltd. operates a factory covering more than 20,000 square meters and employs more than 150 people. The company states that its average daily production exceeds 10,000 units.

The company also says that products undergo pre-shipment inspection and aging tests, covering aspects such as appearance, product performance, and packaging. Another FOXSUR corporate website describes a production capacity exceeding 200,000 units per month, although these figures should be treated as company-provided claims rather than independently audited statistics.

One FOXSUR corporate site states that its products have passed CE and RoHS requirements/certification. It is worth noting that CE/RoHS compliance applies to particular products/configurations and markets, so individual model documentation should be checked when compliance is important.

FOXSUR appears to operate substantially through a B2B/OEM/export + consumer e-commerce model. The company explicitly identifies its customers as foreign importers, wholesalers, and cross-border e-commerce businesses. It says it works with more than 50 Chinese cross-border e-commerce companies and exports products to more than 30 countries.

There are also country/region-specific FOXSUR websites and distributors, including operations targeting markets such as Vietnam and Taiwan. 8 The Taiwanese FOXSUR site, for example, markets the brand specifically around 12V/24V battery charging. The company has also participated in international trade exhibitions, including the Canton Fair and automotive-industry exhibitions.

FOXSUR’s stated corporate vision is “Small tools, big intelligence”. The company says its objective is to become one of consumers’ favorite car-care brands worldwide. Its stated mission is to provide “a good helper for global car care.” Its stated values are Commitment, Pragmatism, Collaboration, and Progress.

FOXSUR products generally have a recognizable consumer-electronics appearance rather than the heavy industrial appearance of traditional workshop chargers. Common characteristics include black/dark housings, bright LCD or digital displays, physical buttons, compact plastic enclosures, battery clamps, automotive-oriented icons, and blue/black branding. In 2021 it introduced “Charge Bro,” a cartoon mascot representing a technician/charger character.

FOXSUR occupies a position between cheap generic automotive electronics and established premium battery-equipment brands. Its basic proposition is essentially offering more features than a basic charger at a lower price than many professional brands. Typical customers might include car owners maintaining vehicles at home, motorcycle owners, DIY mechanics, small workshops, used-car dealers, vehicle enthusiasts, and cross-border automotive-equipment retailers.

FOXSUR should not automatically be placed in the same category as long-established premium specialist manufacturers such as CTEK or NOCO. Its competitive advantage is less about being the oldest or most prestigious battery-equipment company and more about combining extensive functionality with relatively accessible pricing.

Product Hierarchy

• Entry level: 1.5A–6A maintenance chargers (Motorcycles, cars, small batteries)
• Mid-range: 7A–15A smart chargers (Cars, SUVs, larger batteries)
• High-current: 20A–25A 12V/24V chargers (Larger automotive/truck batteries)
• Testing: 12V/24V battery analyzers
• Emergency: Jump starters + air compressors

• Power: Automotive DC/AC inverters

One unusual aspect of researching FOXSUR is that multiple websites identify themselves with the FOXSUR name, including sites associated with different corporate names such as Dongguan Foxsur Electronic Equipment Co., Ltd. and Guangzhou Foxsur Electronic Technology Co., Ltd. For that reason, it is safest not to assume that every FOXSUR-branded website, distributor or historical corporate entity represents exactly the same legal company. For a current brand profile, the Dongguan Foxsur Electronic Equipment Co., Ltd. website at FOXSUR.com is the clearest primary source.
