Everyone uses power banks on a daily basis. For brand-owners, if business travelers are your target audience , you must consider whether the power bank can meet the emergency charging needs of the laptop. Therefore, when selecting a source factory to customize a power bank, you can learn more about it from the following aspects!

1  4 core requirements for customizing power banks for charging laptop

1）USB-C interface + PD fast charging protocol

USB-C port must be configured: both the laptop and the power bank must support the USB-C interface and be connected using dual Type-C fast charging cables; if the laptop has an old-fashioned round hole interface, consider a power bank with a round hole, which does not require an adapter cable!

Compatible with PD fast charging protocol: Support USB PD fast charging protocol (such as PD3.1 140W fast charging is suitable for high-performance notebooks; PD3.0 100W should match with mainstream notebooks (Apple MacBook, Huawei MateBook, etc.).

2）Power matching notebook requirements

Power threshold: Laptop power is mostly 65W and above, thin and Ultrabooks charging power is 30-45W (such as MacBook Air), high-performance notebooks/gaming notebooks are usually 100W~140W or above (MacBook Pro 16-inch 2023 standard 140W charger).if the original notebook charger is 65W, the output power of the PD fast charging power bank should be ≥65W, otherwise the charging will be slow or unavailable.The specific situation depends on the minimum compatible charging power of the laptop.

Note: Gaming laptops typically require >140W, and power banks are mainly used to extend battery life or support low-power tasks.

3）Balance of large capacity and portability

Capacity recommendation: Laptops usually have large capacity, so it is more appropriate to choose a power bank with a capacity of 20000mAh to ensure that it can meet the emergency battery life of the laptop.

Portability limit: Business travelers may often take flights and high-speed trains, so energy ≤100Wh is more appropriate (such as 27600mAh/99.36Wh), which meets the civil aviation and high-speed rail carrying standards.

4）Safety and compatibility

Battery cell solution: For mid-range models, lithium polymer batteries are available, which have high energy density and high safety performance; for high-power high-end models, 21700 batteries are available (low internal resistance, less heat generation, cycle life of 500 times, and longer service life).

Certification essential: It must meet the certification requirements of the target market (China CCC, Europe CE, US FCC, Japan PSE…), etc., to ensure product compliance and reliable quality. In addition, it must pass the UN38.3 mandatory safety test for air transportation to ensure the safety of battery air transportation. The key factory certifications to review include ISO 9001, ISO 14001, and BSCI.

2  key points for brands to choose OEM factories

1） ODM/OEM

OEM: It is suitable for brands with independent R&D capabilities (such as customized APP control, specific functions, etc.), the factory produces according to the design, MOQ≥5000 units.

ODM: The factory provides ready-made solutions, MOQ is 1000-2000 (high-end models as low as 500 units), the customization cycle is short, and new products can be launched quickly.

2）Factorycapabilities of R&D and QC

R&D strength: Inspect the R&D team, patents, equipment, PD 3.1, PPS and other fast charging protocol technology reserves, support for simultaneous fast charging of multiple devices (such as Joway JP365 comes with a retractable cable power bank: Type-C cable and Type-C port output 165W at the same time).

QC process: To meet the reliability test standards, IQC incoming material inspection is required, preferably factory-independent patching, full PCBA board function inspection, full bare metal function inspection, 100% aging test (simulate early use, screen out potential defective products), temperature control protection (such as: multi-level temperature control protection, high and low temperature warning), notebook compatibility test list, etc.

3）Customized service scope

Appearance design: whether the shell supports silicone anti-slip pads, aluminum alloy shells and other processes, brand logos and pattern customization.

Function extension: built-in retractable cable, AC plug, TFT color screen (multi-function display), low current mode (charging headphones), multi-protocol compatibility (PD/PPS/UFCS), etc.

Choosing the right power bank factory can not only meet the efficient charging needs of laptop users, but also create differentiated products for the brand (such as magnetic brackets, fast charging protocols such as PPS/UFCS, built-in retractable cables, TFT color screen digital display, etc.).

FAQ

1） Can a 65W power bank charge a 100W laptop?

Some laptops are compatible but the speed will be reduced. You need to consult the official customer service of the laptop for details

2） Can a laptop power bank charge a laptop and a mobile phone at the same time?

It depends on whether the power bank can charge multiple devices at the same time. If the speed is reduced to slow charging when multiple devices are charged at the same time, it will not available.
