Sourcing DS4400 power bank (Packs) from MWI Electron Ltd. - Taiwan Import Guide
Before placing an order, confirm the physical condition of the power bank units: check for swelling, leakage, or loose casing. Verify that all USB ports are functional and that the LED indicator responds correctly. Request a photo of a sample unit under normal lighting. Do not accept units with visible damage, missing labels, or mismatched serial numbers.
Confirm lead time with the supplier, as stock may be held in Taiwan or shipped from mainland China. Incoterms are typically FOB Taipei Port, with payment via T/T in advance. Packaging is usually blister cards in cartons of 10 or 50 units. Ensure the carton includes a list of contents and batch number for traceability.
Upon receipt, perform a functional test: charge the unit fully, then discharge it while connected to two devices. Measure output voltage under load with a multimeter. Check for excessive heat generation during use. Retain packaging and test logs for warranty claims. Request a certificate of compliance if required for customs clearance in your country.
