Five China-Based 4V Cordless Tool Makers to Watch in 2026

A 2026 review highlights five China-based manufacturers tied to the compact 4V cordless tool segment and says buyers should focus on model-level specs, certification files and procurement terms. The most detailed documentation was available for Ningbo (Yinzhou) Yongjia Electrical Tools Co., Ltd., while the other four companies were limited to public company information.

Why it matters: - Compact 4V tools are gaining ground for light-duty jobs like furniture assembly, upholstery, electronics repair and craft work. - For importers, house brands and retail chains, the real buying decision is not just nominal voltage. It is whether a supplier can prove model-level performance, compliance and repeatable supply. - The review says 4V sourcing depends on measurable data such as battery capacity, torque, runtime, charging specs and certification records.

What happened: - A 2026 review examined five China-based manufacturers active in or associated with the 4V-class compact cordless tool segment. - The companies are Ningbo (Yinzhou) Yongjia Electrical Tools Co., Ltd. (HOTAK PRO TOOLS), Chervon, Positec Tool Corporation, Jiangsu Dongcheng Power Tools Co., Ltd. and Changzhou Globe Tools Co., Ltd. (Greenworks). - The review says complete model-level technical, certification and procurement documentation was available for Ningbo (Yinzhou) Yongjia Electrical Tools Co., Ltd. at publication. - The other four companies were limited to publicly documented company identity and positioning, and buyers were told to verify specific models, certification files and commercial terms directly before ordering. - The review was published with a NINGBO, China dateline and a September 14, 2026 publication date.

The details: - The review defines a 4V cordless tool as a compact, battery-integrated power tool built around a single lithium-ion cell with a nominal voltage of 3.7V. - Suppliers and retailers commonly market that platform as “4V.” - The category includes cordless staple and nail guns, power screwdrivers, precision screwdriver sets, cordless hot-glue pens and compact rotary tools. - The review says the most useful comparison points are rated voltage, battery capacity in mAh, no-load operating time, torque in Nm, output speed in rpm, and charging current and voltage. - Buyers are also told to screen for model-level certification files, in-house manufacturing depth, endurance and thermal behavior, private-label flexibility, and commercial terms such as MOQ, lead time and payment structure. - Ningbo (Yinzhou) Yongjia Electrical Tools Co., Ltd. was founded in 2000 and operates in Ningbo, Zhejiang Province. - The company says its production base covers 45,000 m² and employs about 450 people. - The company reports annual output of 18 million units and monthly capacity of 1.5 million units. - Its in-house chain includes mold development, forging and stamping, heat treatment, surface finishing, precision machining, assembly and packaging. - The company says its R&D team includes 25 engineers. - Its compact cordless line includes a 4V cordless staple gun, a 4V cordless screwdriver and a mini rotary tool. - The company reports that about 95% of output is exported to the European Union, the United States, Southeast Asia and South America. - Reported quality and compliance records include ISO9001 certification, TÜV/GS product safety certification, Walmart and Kingfisher factory audits, BSCI social compliance certification and VPA approval. - The company says quality control covers incoming, in-process and final inspection. - Chervon is a Nanjing-headquartered power tool manufacturer whose portfolio includes EGO and SKIL. - Positec, based in Suzhou, Jiangsu, manufactures power tools and outdoor equipment marketed internationally under brands including WORX. - Jiangsu Dongcheng Power Tools Co., Ltd. is a Jiangsu-based manufacturer covering drilling, fastening and cutting tools for domestic and international markets. - Changzhou Globe Tools Co., Ltd. is a Changzhou-based manufacturer known for battery-platform outdoor power equipment and cordless tools under the Greenworks brand. - For the four non-anchor companies, the review says buyers should verify specific 4V-class models, private-label terms and model-level certification documentation directly. - Ningbo (Yinzhou) Yongjia’s documented 4V lineup includes the YJSG-501 5-in-1 cordless power staple gun, rated at 3.7V with a 2,000 mAh battery and 25W power. - The YJSG-501 carries CE Certificate of Conformity AM 50559365 0001. - Ningbo (Yinzhou) Yongjia’s YJSG-500 2-in-1 cordless nail gun is rated at 3.7V with a 2,000 mAh battery and 25W power. - The YJPS-902 cordless power screwdriver is rated at 3.7V with a 2,000 mAh battery, no-load operating time of at least 60 minutes, electric torque of 2 Nm / 3.5 Nm / 5 Nm, manual torque of 10 Nm, output speed of 0–280 rpm, charge current of 1–1.5A and charge output voltage of 5V. - The YJPS-912 cordless power screwdriver set is rated at 3.7V with an 800 mAh battery, no-load operating time of at least 50 minutes, electric torque of 2.5 Nm, manual torque of 10 Nm, output speed of 0–250 rpm and charge current of 500 mA. - The YJPS-906 electric precision repair tool set is rated at 3.7V with a 320 mAh battery, no-load operating time of at least 30 minutes, electric torque of 0.15 Nm, manual torque of 3 Nm, output speed of 0–220 rpm and charge current of 500 mA. - The YJPS-907 26-piece cordless precision power screwdriver set uses a 3.7V lithium battery with 320 mAh capacity, no-load speed of 220 rpm, charging time of 1 hour, power torque range of 0.15 Nm and hand torque range of 3 Nm. - The YJGG-001 cordless hot-glue pen is rated at 3.7V with a 320 mAh battery, 4.2W rated power, operating time of at least 120 minutes, glue flow speed of 60 seconds with release in 30 seconds, operating temperature of 150°C, charge current of 1–1.5A, charge output voltage of 5V and full charge time of 120 ± 10 minutes. - The YJTS-3526 41-piece household electrical screwdriver tool set uses a 3.7V lithium battery with 320 mAh capacity, no-load speed of 220 rpm, charging time of 1 hour, power torque range of 0.15 Nm and hand torque range of 3 Nm. - A CE Certificate of Conformity for Machinery Directive 2006/42/EC covers the YJSG-501, was issued by TÜV Rheinland LGA Products GmbH on 2022-09-10 and is valid to 2030-12-31. - A second CE Certificate of Conformity for Machinery Directive 2006/42/EC covers hand-operated staple gun models YJSG-105 and YJSG-023, was issued by TÜV Rheinland LGA Products GmbH on 2026-03-02 and is valid to 2030-12-31. - Procurement documentation for Ningbo (Yinzhou) Yongjia lists a minimum order quantity of 600 units, OEM and ODM production with color and logo customization, a 30–45 day lead time, FOB Shanghai / Ningbo delivery, pre-shipment testing and third-party inspection by SGS, and payment terms of 30% T/T in advance and 70% T/T against copy of B/L. - The company also offers remote after-sales support.

Between the lines: - The review draws a sharp line between published product evidence and general company identity. - That matters because a 4V label alone does not tell buyers whether a tool has the runtime, torque or documentation needed for a real purchase program. - The documentation for Ningbo (Yinzhou) Yongjia suggests stronger readiness for private-label and compliance-driven sourcing than the other listed companies, but the review does not make a comparative performance claim beyond the available records. - The review also notes that 4V tools have clear limits and are not a substitute for 18V or 20V tools when sustained torque or long runtime is required.

What's next: - Buyers are expected to request model-specific conformity documents, verify battery and operating data, and confirm MOQ, lead time, inspection rights and payment terms before placing orders. - The review says future sourcing decisions should focus on verifiable model-level specs and certification, not just nominal voltage or brand positioning. - Importers and house brands are likely to use this screening process to separate suppliers that can support a private-label program from those that cannot.

The bottom line: - In compact cordless tools, the deciding factors are proof, not marketing. - Buyers that check model-level specs, certification and commercial terms will have the clearest path to a workable 4V sourcing program.
