Our custom manufacturing process is designed to turn innovative ideas into reliable,market ready products-efficiently and at scale. From custom design and rapid prototyping to component integration and performance testing, every stage is handled by our in-house engineering team.

We work closely with global partners to co-develop products that align with brand positioning, technical requirements, and market demand. Unlike conventional manufacturers, our custom manufacturing model emphasizes flexibility, enabling tailored materials, unique form factors, and optimized production timelines.

Custom Manufacturing Process for Jump Starters

All CARKU’s ODM tools — including jump starters, power stations, and starting batteries. They are engineered for professional-grade performance.
Each product is manufactured under a smart manufacturing system, featuring rigorous Grade-A battery cell selection, precision soldering and hand-assembled, and aging tests to ensure reliability. Our factory supports both small-batch prototyping and mass production to meet different partner needs.

1. Customization: Customers provide product parameters, or our R&D team develops design solutions and prototypes based on the customer’s vision.

2. Sample Confirmation: Samples are submitted for review and feedback, with rapid prototyping available within 7 days.

3. Approval & Production:Upon final confirmation, we initiate mass production with full process traceability.

4. Quality control & Delivery: Every unit undergoes final inspection and certification testing (UL / CE / RoHS / FCC / PSE) before delivery to ensure global compliance and reliability.

Custom Design on Automotive Jump Starter Equipments

CARKU’s ODM jump starters are built with a deep understanding of automotive electrical systems and user safety requirements. Our custom design capability covers everything from battery pack architecture to core technology integration and brand-oriented product styling.

At the heart of every model is our DSLI-IV patented core technology, delivering faster cranking speed, stronger peak current, and enhanced safety compared to conventional jump starters. Each product adopts Grade-A high-rate lithium battery cells, capable of instantly starting vehicles of all sizes, from motorcycles to heavy-duty trucks — even after two years of storage without power drain.

To meet the needs of global brands, we provide customized exterior and brand solutions, allowing partners to stick their brand identity on our products with flexible color, texture, and packaging options. Our compact, ergonomic designs combine multi-functional integration — jump start, LED lighting, power bank, air pump, and more — making them ideal companions for fleet operations, road trips, and emergency rescue.

Every design goes through strict quality inspection, assembly verification, and aging tests to ensure consistent reliability from the first prototype to full-scale mass production. With 10 intelligent protection systems and 360° safety guarding, CARKU guarantees stable performance across all environments and vehicle types.

What Battery Technology Do We Use On Power Station?

All our portable power stations utilize LiFePO4 (Lithium Iron Phosphate) battery technology, from compact 100Wh models to high-capacity 2000Wh+ power stations. LiFePO4 represents a distinct lithium battery chemistry that offers superior safety, longevity, and thermal stability compared to standard lithium-ion (NMC/NCM) batteries.

Why Choose Our LiFePO4 Power Station ODM Solutions?

Our portable power station manufacturing represents the evolution of our battery application technology mastery, taking the same safety-first approach and reliability standards into a complete power station solution for diverse applications.

1. Safe and premium-grade LiFePO4 cells

Our proprietary LIFEBMS features:

- Premium Lithium Iron Phosphate cells

- Proprietary battery management system with real-time monitoring

- 3,000+ cycle lifespan (6x longer than standard lithium-ion)

-Full certifications: UN38.3, UL2743, CE, FCC, RoHS

2. High-performance power delivery

- Power range:300W-3000W

- Pure sine wave inverter safe for all electroncis

- >90% conversion efficiency

3. Extended Product Lifespan and Super Powerful

One of our key manufacturing advantages lies in longevity and scalability. Our portable power stations are built with premium LiFePO4 cells that deliver over 3,000 full charge/discharge cycles while maintaining 80% capacity retention.

In practical terms, this translates to more than 10 years of regular daily use, significantly outlasting conventional lithium-ion alternatives.

4.Integrated Jump Start Function

Our jump start module delivers up to 2000A peak current, sufficient to instantly start gasoline engines up to 8.0L and diesel engines up to 6.0L — covering everything from compact cars to full-size pickup trucks and SUVs.

Some units are designed with integrated multi-function features, including an air compressor, power bank capability for charging mobile devices, and a built-in LED flashlight, making it a truly all-in-one portable jump starters.

In  Conclusion

From exterior design to internal battery architecture, CARKU provides a one-stop ODM service that bridges design, engineering, and mass production.

Our Huizhou factory, with an investment exceeding 200 million RMB and a total floor area of 110,000㎡, delivers strong R&D and manufacturing capabilities for both automotive jump starters and portable power stations, achieving an annual output value of over 3 billion RMB.

In 2024, we expanded our global footprint by establishing a new factory in Indonesia, enhancing production capacity and shortening delivery cycles to the Southeast Asian market.

Backed by advanced facilities and a professional R&D team, CARKU continues to drive growth in both self-owned brand development and export-oriented OEM/ODM manufacturing, powered by our dual strengths in production and intelligent manufacturing.
