With rapid progress in power bank and wireless-charging technology, features have moved well beyond the basics. Power banks with built-in wireless charging are now widely favoured. Brands planning custom wireless-charging power banks are focusing on differentiation to satisfy higher user expectations. Which factors matter most when you define your brief? If you are sourcing a dependable OEM/ODM manufacturing partner, this guide is a helpful starting point.

1 Eight Essentials for Custom Wireless-Charging Power Banks

10 September 2025 Apple Autumn Launch: With the iPhone 17 series bringing a step-change in wireless charging, custom power banks need to evolve in lockstep. Below are the key points to factor into your brief:

1）Power and fast-charging protocols

For convenience and broad device coverage, shortlist Qi 2.2 at 25 W and ensure compatibility with fast charging on the iPhone 17 line-up. For wired charging, target PD 40 W or higher. Where your audience warrants it, include PPS, UFCS and SCP. In practice, a multi-protocol design maximises user reach and reduces compatibility risks.

2）Thermal performance

Wireless charging runs hotter—especially as power levels rise—so thermal design deserves extra care versus conventional power banks. Combine sound mechanical design with effective thermal interface materials, an aluminium alloy shell, and robust temperature management to keep surfaces comfortable and electronics protected.

Example: The JOWAY JP353 adopts a flip-cover, split-body construction with an aluminium support plate to accelerate heat dissipation during wireless charging. [Click to learn more.]

3）Battery cell selection

As the heart of any power bank, the battery cell—and the strength of its supplier—deserves close scrutiny. Prioritise reputable branded cells and assess both chemistry and build quality. Request the manufacturer’s reliability test reports for the chosen cells, and state the cell materials and required reliability tests explicitly in the contract.

4）Safety and certification

Safety and compliance are critical. They determine market access and protect users in real-world use. Factor in transport and environmental requirements, including CE, FCC, RoHS and UN 38.3. Ensure the enclosure material meets recognised flame-retardant standards.

5）Capacity and portability

Capacity must be balanced with volume and weight to keep the product easy to carry day to day and acceptable on common transport modes. Aim to satisfy carry rules across buses, underground/metro, mainline and high-speed rail, and aircraft. A foldable form factor further improves everyday portability.

6）Enclosure materials and finishing

Most power bank housings use aluminium alloy or PC+ABS. For magnetic wireless charging, strengthen holding force by adding magnets and/or a silicone contact pad. Typical finishes include a moulded texture, spray coating, and an anodised, sandblasted surface [Click to learn more]. Logos and regulatory markings can be applied by laser engraving or screen printing. Assess durability and total cost when selecting both materials and finishing methods.

7）Multi-function combinations

Wireless-charging power banks can integrate a kickstand, deliver fast charging over both wireless and wired outputs, support pass-through charging, and provide a clear status display. The right combination of functions increases user value and sharpens product differentiation.

For example: The JOWAY JP339 pairs wireless charging with a stand set at a practical height. It supports concurrent fast charging via wireless and wired outputs. A side USB-C port can charge a smartwatch, while dual USB-C delivers up to PD 100 W and PPS 100 W. A TFT colour display presents multi-function readouts [Click to see details].

8）Delivery lead time

Assess the factory’s daily output and whether it runs fully automated SMT lines and automated assembly lines. Confirm the end-to-end project lead time and whether the supplier can deliver on time, to the agreed quality and quantity.

2 Selecting a professional power bank manufacturer

1） R&D capability

Prioritise manufacturers with robust R&D. They should offer advanced technical solutions, stay aligned with market shifts, and demonstrate continuous innovation with rapid new-product iteration.

2） Quality control

Evaluate the organisation’s quality framework: ISO 9001 for quality management, ISO 14001 for environmental management, and QC 080000 for hazardous substances. Review lab assets, the reliability test matrix, the quality team, and the end-to-end quality control procedures.

3 ） Factory qualifications

Look for credentials such as AAA credit rating, National High-Tech Enterprise status, BSCI social compliance certification, SQP quality audit certification, and RoHS environmental compliance.

4） Proven track record

Ask prospective contract manufacturers which tier-one brands they currently serve. High-profile brands typically impose rigorous standards on partner capability and qualifications, allowing you to gauge a factory’s real-world competence through its client portfolio.
