Product Development & Manufacturing Capabilities

With industry experience dating back to 2010, our team brings more than 10 years of experience in wireless charging and related consumer electronics.

KingzyTech's product development and manufacturing capabilities include industrial design, R&D, electronic and structural development, tooling, injection molding and manufacturing. Our workflow also covers material sourcing, product testing, quality control and after-sales support.

These capabilities allow our teams to coordinate product development and production across multiple stages rather than treating design, engineering, tooling and manufacturing as isolated processes.

For B2B customers, this is particularly important when a project involves changes to product appearance, internal structure, electronics, charging configuration, materials, tooling or packaging.

Based in Shenzhen, China

KingzyTech operates from Shenzhen, China, a major center for consumer electronics product development and supply-chain collaboration.

Our Shenzhen location supports coordination across industrial design, R&D, electronic and structural development, component sourcing, tooling, injection molding, manufacturing, product testing and quality control.

For wireless charging projects, product structure, charging configuration, electronic components, materials, appearance and packaging may need to be evaluated together. Close coordination between these stages helps move projects from product evaluation and development toward sampling and production.

Our 5,000 m² manufacturing facility, five production lines and team of more than 150 employees support both existing product orders and customized B2B projects.

OEM, ODM & Ready-to-Ship Product Options

KingzyTech supports different sourcing models according to customer and project requirements.

OEM projects currently represent approximately 50% of our business, ODM projects account for approximately 40%, and ready-to-ship neutral products represent approximately 10%.

For buyers who already have a suitable product direction, OEM projects can focus on requirements such as branding, product color, packaging or other applicable customization.

For customers developing a more differentiated product, ODM projects can extend into industrial design, product structure, electronics, firmware, tooling and new product development.

For buyers who do not require customization, ready-to-ship neutral products provide another sourcing option based on available models and current product availability.

OEM/ODM Customization Capabilities

KingzyTech supports customization at different levels, from branding and appearance changes to product engineering and new product development.

Our customization capabilities include:

• Logo & Branding — branding customization for applicable products
• Color — product color customization according to project requirements
• Packaging — customized packaging for private-label and branded projects
• Housing & Appearance — exterior design and housing development
• Product Structure — structural development and modification
• PCB & Electronics — PCB and electronic solution development for applicable projects
• Firmware — firmware development or modification according to product functions
• Mold — tooling and mold development for customized structures and housings
• New Product Development — development from an initial product idea through engineering and production

The available customization scope depends on the selected product and individual project requirements. Specific requirements are evaluated before development or production begins.

ODM Product Development: From Idea to Production

KingzyTech supports end-to-end ODM product development for customers who want to turn an initial product idea into a physical product.

A typical ODM development process can include:

Product Idea & Requirements → Industrial Design → Electronic & Structural Development → Prototype Development → Tooling → Sample Evaluation → Product Testing & Validation → Production Preparation → Manufacturing → Quality Control → Final Product

At the beginning of a project, our team works with the customer to understand the intended product, target users, target devices, charging requirements, functions, appearance, destination market and other project requirements.

Industrial design and R&D then support the development of product appearance, structure, electronics and charging configuration. Prototype development and sample evaluation allow the product direction to be reviewed before tooling and production requirements are finalized.

Testing and validation are carried out as the project moves toward production, followed by manufacturing and quality control. This enables KingzyTech to support an ODM project from the customer's initial idea through to the finished physical product.

Quality Control & Wireless Charging Product Testing

Quality control is integrated into different stages of our development and production process.

KingzyTech's quality procedures include incoming material inspection, in-process inspection and finished product inspection to identify product or production issues at different stages.

For wireless charging products, our testing can include:

• Wireless charging power and output testing
• Charging distance testing
• Temperature-rise testing
• Device compatibility testing
• Aging testing

These tests support the evaluation of charging performance, operating conditions and product consistency during product development, sample evaluation and production.

Testing requirements may vary according to product design, charging configuration and project requirements. For B2B projects requiring specific certification, testing or documentation, the applicable requirements should be confirmed for the selected model and destination market.

Wireless Charging Product Focus

The SIYOUNI portfolio covers wireless charging solutions for different devices, product formats and application scenarios.

Our current product categories include Qi2.2 wireless chargers, 3-in-1 wireless charging stations, wireless charging pads, wireless chargers with speaker and light functions, magnetic wireless power banks, Apple Watch chargers, multi-device charging cables and furniture wireless charging solutions.

Because wireless standards, charging positions, output configurations and device support vary between products, specifications are evaluated at the individual model level.

B2B buyers should confirm the applicable wireless charging standard, charging output, input requirements, supported devices, product structure and required documentation for the specific model under evaluation rather than applying specifications from one product to another.

International B2B Market Experience

KingzyTech serves customers across international markets including the United States, Europe, Australia, India, Japan, South Korea and Southeast Asia, as well as other regions.

Our experience across different markets gives our team exposure to varied product positioning, device requirements, packaging needs and sourcing expectations.

For market-specific certification, compliance or documentation requirements, buyers should identify the destination market and selected product so the applicable requirements can be evaluated at the model and project level.

Production Capacity & Lead Time

KingzyTech operates five production lines with a monthly production capacity of more than 200,000 units.

Standard production lead time is typically 15–30 days. Actual lead time may vary depending on the product model, order quantity, customization requirements, packaging and production schedule. The final production and delivery schedule is confirmed for each order.

This combination of product development, customization and production capabilities supports both existing product sourcing and customized OEM/ODM projects.

B2B buyers can explore SIYOUNI products according to charging format, target devices and intended application, including Qi2.2 wireless chargers, 3-in-1 wireless charging stations, wireless charging pads, magnetic wireless power banks, Apple Watch chargers and furniture wireless charging solutions.

KingzyTech also publishes buying guides, product comparisons and application-focused articles covering wireless charging standards, charging configurations, device support and product selection to help buyers evaluate products before sourcing.
