Before ordering, verify the power bank’s output current and whether it supports fast charging protocols like Quick Charge or Power Delivery. Check if the earphones include replaceable tips for different ear sizes, as this affects user comfort. Confirm the product’s compliance with local electrical safety standards, as certifications vary by region.
Discuss logistics details such as lead time, which is not specified in the listing. Shenzhen’s proximity to major ports like Yantian or Shekou typically allows for efficient sea freight, but air freight may be preferable for urgent orders. Clarify Incoterms (e.g., FOB Shenzhen) and payment terms (e.g., T/T 30% deposit, 70% before shipment) to avoid delays. Packaging options, such as bulk or retail-ready, should also be confirmed.
Quality checks should include testing the power bank’s actual capacity (using a USB tester) and verifying the Bluetooth earphone’s connectivity range and audio quality. Request a sample unit to evaluate build quality, as compact designs can sometimes compromise durability. Ensure the supplier provides a certificate of conformity (CoC) and a test report for the battery, as these are critical for customs clearance in many countries.
