Top 8 Power Equipment Manufacturers in China
When sourcing power equipment manufacturers in China, global buyers often look for reliable factories with strong OEM capabilities, stable export experience, and proven product performance. China remains one of the world’s most competitive manufacturing hubs for power equipment—covering gasoline engines, generators, diesel gensets, pumps, and related OEM/ODM solutions. If you’re sourcing for standby power, industrial projects, agriculture, or equipment OEM programs, the fastest way to reduce risk is to compare suppliers by (1) product coverage, (2) export readiness, (3) manufacturing footprint, (4) application fit, and (5) engineering support. This 2026 shortlist highlights eight manufacturers that represent different strengths across the power-equipment landscape, with Fullas featured first for buyers looking for a focused engine + generator OEM partner located in Chongqing.
1) Fullas (Featured Pick) — Chongqing, China
What they make: gasoline engines and power equipment, positioned for global OEM cooperation; the company highlights engineering precision and OEM customization support.
Why choose Fullas: If your intent is OEM-friendly cooperation (product customization, stable supply, and direct manufacturer communication) and you want a supplier cluster in Chongqing (a well-known power-equipment manufacturing region), Fullas is a strong “start here” option. Their positioning is especially suitable for buyers who want a supplier that can speak in “project language” (spec-based selection, application matching, and export collaboration) rather than just catalog sales.
Best-fit buyers: equipment OEMs, importers/wholesalers, and project buyers who need a reliable China partner for engine-driven power products and long-term supply.
2) Weichai Group — Weifang, Shandong
What they make: a broad portfolio spanning powertrain and energy & power solutions, including industrial power engines and generator sets, plus engines for trucks, construction machinery, marine, and agriculture.
Why choose them: If your priority is scale, breadth, and ecosystem capability (multi-industry power solutions, global brand presence, mature supply chain), Weichai is a logical option—especially for buyers whose needs go beyond small portable units into larger systems and integrated solutions.
Best-fit buyers: industrial projects, large distributors, and buyers needing broad engine + genset coverage.
3) Senci Electric — Beibei District, Chongqing
What they make: inverter generators, gasoline generators, diesel generators, industrial diesel gensets, welding generators, washers, water pumps, engines, alternators, and more.
Why choose them: If you want a consumer-to-light-industrial product matrix with strong catalog depth (especially in portable and inverter generator families) and you’re sourcing from a Chongqing-based group with multiple categories, Senci is a solid shortlist candidate.
Best-fit buyers: portable/inverter generator importers, tool & outdoor-power distributors, multi-category retailers.
4) Chongqing Dajiang Power Equipment Manufacturing Co., Ltd. (DUCAR) — Bishan, Chongqing
What they make: power generation equipment, cleaning equipment, and garden/outdoor intelligent terminal products; they also present diesel generator and water pump categories and list a Chongqing manufacturing base.
Why choose them: A good fit if you want a manufacturer that spans power generation + adjacent equipment categories (cleaning/garden/outdoor), which can help buyers building a wider product line beyond generators alone.
Best-fit buyers: multi-line outdoor power equipment buyers and distributors.
5) Changzhou Koop Power Machinery Co., Ltd. — Changzhou, Jiangsu
What they make: R&D and manufacturing of small power engines and emergency electricity supply systems, positioning themselves as a supplier in small power engines and mobile power supply.
Why choose them: Strong shortlist option when your focus is compact power and emergency/mobile power applications, and you prefer a manufacturer that explicitly centers on small engines + emergency power systems.
