We are a Guangdong-based supply-chain solutions provider specializing in portable power stations and solar energy products. We serve brands,distributors, Amazon sellers, and e-commerce businesses worldwide.

Instead of owning our own manufacturing workshop, we deeply cooperate with multiple qualified energy‑storage factories. Our core value is to match the most suitable manufacturing resource according to client’s target market, budget and order volume.

We understand most overseas B‑buyers face pain points: high OEM MOQ, expensive new certification cost, single‑factory capacity risk and unclear cost comparison. Our team solves these pain points by multi‑factory resource integration.

Our main service:

• Energy storage model recommendation for different regions
• Private label OEM & packaging customization
• Cost‑optimized solution under same quality
• Sample arrangement & whole‑order follow‑up
• 100% QC inspection before shipment
• Provide factory‑issued certification copies for customs
• Sea/air/express shipping with DDP option
  

Our goal: Become your reliable long‑term China sourcing partner for energy‑storage products.

Our team brings 8+ years of hands-on experience in electronics export,factory sourcing, and international trade.

Before focusing on portable power stations, we helped overseas buyers source PCBA and electronic products from Chinese manufacturers — dealing with the same challenges that energy storage buyers face today:
inconsistent quality, communication gaps, incomplete certifications, and zero accountability after shipment.

We built Jiefu to solve exactly these problems. We assembled a vetted network of certified energy storage manufacturing partners, and now we manage the entire process — from sampling and production oversight to
QC inspection and shipping — so our clients get reliable products without the headaches.

Our approach is straightforward: one accountable point of contact, transparent communication, and products that pass inspection before they leave the factory.
