Import Doca D579 Power Bank — Buy in Bulk from Supplier in China

The Doca D579 Power Bank is a portable lithium-ion charging device with a nominal capacity of 20000mAh, outputting 5V/3.1A total across three USB-A ports. It weighs 350g and measures 155mm x 75mm x 18mm, designed for portability without compromising power delivery. The unit supports pass-through charging, allowing the power bank to be recharged while simultaneously powering connected devices.

The battery uses 18650 lithium-ion cells with a standard cycle life of 500 cycles at 80% retention. Internal protection circuits include overcharge, over-discharge, short-circuit, and temperature safeguards. The casing is constructed from ABS plastic with a matte finish, typical for industrial-grade power banks in this capacity range. No fast-charging protocols like PD or QC are listed, so output is limited to standard 5V charging.

This model is commonly purchased by logistics firms, event coordinators, and travel agencies for bulk distribution to clients or staff. Buyers often source it for use in remote field operations, corporate travel kits, and educational institutions. Trade terms include FOB Shenzhen and CIF destination ports, with MOQ starting at 500 units. Packaging is in white retail boxes, 10 units per carton, with no branded inserts beyond product labels.
