Power Bank Manufacturing and Processing Factory in Vietnam
Power Bank Manufacturing and Processing Factory in Vietnam
In the field of electronics manufacturing, power banks are one of the products that require a high degree of precision and technical control. It's not simply about the mAh capacity printed on the box; the true value of a power bank lies in its...battery core structure, control circuit, charging efficiency, component durability, and long-term maintainability.Therefore, businesses are looking for...Power bank manufacturing and processing factory in VietnamPeople are increasingly paying more attention to technical specifications rather than just looking at the price.
Power bank manufacturing is not just about assembly MyMy Technology
In professional workshops, power banks are considered a miniaturized energy storage and distribution systems, include:
- Lithium battery cells (Li-Ion or Li-Po)
- Battery Management System (BMS)
- Charging and discharging circuit (PD, QC)
- Connectors, protective components
- Protective casing and heat sink
Each component directly impacts lifespan, safety, and user experience.
The actual value of the mAh capacity parameter.
Understanding mAh correctly in power banks
Battery capacity (mAh) indicates the ability to store electrical energy, butThis doesn't mean 100% of the storage capacity is being used.In fact:
- Conversion rates typically range from 60–75%.
- The energy loss comes from the voltage converter circuit, heat, and the charging cable.
For example:
- 10,000mAh power bank → actual usable capacity ~6,000–7,000mAh
- 20,000mAh power bank → actual capacity ~12,000–14,000mAh
Reputable processing workshops in Vietnam usuallypublicly disclose charging performanceTo help businesses understand the true value of their products.
Common capacity ranges in machining
- 5.000 – 10.000mAh: compact, lightweight, prioritizing portability
- 15.000 – 20.000mAhMultifunctional, charges multiple devices.
- 24,000mAh or moreServing laptops and high-power devices.
Choosing the right storage capacity not only affects the price but also entails changes in...size, weight, and shell structure.
Size and weight – technical factors that are rarely discussed.
In the manufacturing of power banks,size and weightIt is inseparable from battery capacity and power output.
The relationship between capacity and volume
- The larger the lithium battery cell, the greater the weight.
- High charging power → larger circuit → requires more heat dissipation space
Here's a real-world example:
- 10,000mAh charger: ~180–230g
- 20,000mAh power bank: ~400–500g
- 24,000mAh high-capacity charger: ~600–650g
Processing workshops in Vietnam often have toOptimizing the internal component layoutTo reduce thickness and avoid the feeling of a "heavy battery" when held in the hand.
Optimizing dimensions in machining
Commonly applied solutions:
- Use high-energy density battery cells.
- Compact multi-layer circuit design
- Optimizing shell thickness while maintaining safety.
This is the major difference between professional manufacturing and substandard goods.
The battery core inside – the determining factor for durability.
Lithium battery core and lifespan
Most commercially manufactured power banks currently use:
- Lithium-Ion (Li-Ion): stable, reasonable cost
- Lithium Polymer (Li-Po)Thin, lightweight, and more expensive.
A good quality battery core must ensure:
- Charge/discharge cycle ≥ 500–800 times
- Maintain stable capacity over time.
- No battery swelling, no overheating.
Maintainability in machining
For professional manufacturing plants, maintainability is considered right from the design stage:
- Separate battery circuit, easy to check for faults.
- Standard battery cells, easy to replace.
- Do not solder the entire battery pack in place.
This is especially important for businesses that place large orders and require long-term warranties.
Battery management circuit – the “brain” of the power bank.
A quality power bank is indispensable BMS circuit with the following functions:
- Overcurrent protection
- Overvoltage protection
- Overheat protection
- Short circuit protection
- Automatically shuts off when the battery is full or completely discharged.
In addition, modern circuits also support:
- Power Delivery (PD)
- Quick Charge (QC)
- Intelligent current distribution when charging multiple devices.
This is why well-manufactured power banks offer greater stability when charging 2–3 devices simultaneously.
