从China供应商批量进口5200mah Portable Power Bank For Mobile Phones

The 5200mAh portable power bank from Shenzhen Lianqiang Chuangzhan Tech Co., Ltd. measures 75 x 67 x 23 mm and weighs 240g, housing a lithium-ion cell rated at 5200mAh nominal capacity. The unit outputs through standard USB-A ports with 5V/1A or 5V/2.1A typical delivery, sufficient for roughly 1.5 to 2 full charges of a standard 3000mAh smartphone battery. Available colour combinations include white paired with coffee, blue, army green, or light grey finishes.

The enclosure uses ABS plastic with a matte or gloss surface treatment depending on the colour variant. Internal circuitry incorporates over-voltage, over-current, and thermal protection ICs to prevent battery swelling or device damage during charge cycles. The 5200mAh rating at 3.7V cell voltage translates to roughly 19.24Wh total energy content, a standard figure for pocket-sized power banks in the 5000-6000mAh segment. Typical cell chemistry is lithium cobalt oxide or lithium nickel manganese cobalt, chosen for energy density in compact applications.

Target buyers include mobile accessory wholesalers, corporate gift suppliers, travel retail distributors, and electronics retailers serving commuters and frequent travellers. The form factor suits pocket or bag carry for daily use, business travel, and outdoor activities where mains access is intermittent. Buyers should confirm with the supplier the exact output current per port, cycle life rating, and whether the cell carries UN38.3 transport certification for air-freight shipment.

Shenzhen Lianqiang Chuangzhan Tech Co., Ltd. is located at 401, Building C5, Huatongyuan Logistics Minzhi Avenue, Longhua New District, Shenzhen 518131, Guangdong, China.
