BATTERY DESIGN & EU MARKET PLANNING

Removable batteries.
Start with V6 and V7.

Our V6 and V7 USB desk fans feature removable 4,000 mAh batteries. As a removable battery desktop fan manufacturer, we help brands and distributors build distinctive collections with custom colors, logos and packaging.

Planning replaceable battery portable fan wholesale? Start with these two desk fan designs and share your battery access and replacement requirements. If you are looking for a removable battery handheld fan manufacturer, send us your OEM brief so we can review the required design and confirm availability for your selected handheld model.

Looking for an EU battery directive compliant usb fan or an EU regulation compliant mini fan factory? Plan your brief around the EU Battery Regulation (EU) 2023/1542. Its Article 11 removability and replaceability requirements apply from February 18, 2027, with specified exceptions. Confirm battery access, compatible replacements, user instructions, spare-battery arrangements and applicable documentation for your selected configuration before EU supply.

QUALITY CONTROL

Quality control
behind every project.

Our QC systems focus on assembly consistency, functional performance and product reliability. Product evaluation can include aging tests, airflow and noise assessment, drop testing and battery safety testing, according to the selected model and project requirements.

During sampling, we work with you to confirm the configuration and evaluation criteria that matter to your market. This establishes a clear reference for production and repeat orders.

  1. Agree the specification and evaluation criteria.
  2. Review the sample and confirm your configuration.
  3. Use the approved reference for production.
