从China供应商批量进口Adapter Power For Dell 19.5v3.34a(7.4*5.0)

Shenzhen Huruishop Electronic Co., Ltd. supplies a replacement AC adapter for Dell laptops requiring 19.5 volts DC at 3.34 amperes, with a coaxial barrel connector measuring 7.4 mm outer diameter by 5.0 mm inner diameter. This 65-watt class adapter (19.5 V x 3.34 A = 65.13 W) targets business-grade Dell Latitude, Inspiron, and Precision series machines from roughly 2008-2015 vintage with the central-pin barrel design. The 7.4 by 5.0 mm connector format incorporates a central signal pin that communicates adapter wattage to the laptop's charge controller, preventing underpowered operation. Buyers should confirm exact laptop compatibility, as Dell later transitioned to 4.5 mm and USB-C formats.

The adapter construction centres on a switch-mode power supply topology, typical for 65 W notebook adapters, with implied over-voltage, under-voltage, and short-circuit protection per the supplier's description. The 7.4 by 5.0 mm barrel connector with central pin is a Dell-specific mechanical standard, not a universal format, which limits cross-brand compatibility. AC input is presumed universal (100-240 VAC, 50-60 Hz), though buyers must verify this with the supplier as it is not explicitly stated. Output cable length, gauge, and strain relief design affect portability and longevity, with typical OEM-equivalent cables ranging 1.8 to 2.5 metres in PVC or TPE jacketing.

Primary applications include corporate IT fleet refresh, education sector device maintenance, and healthcare administrative laptop support where Dell hardware remains in service. The compact format targets mobile professionals requiring replacement or secondary adapters for home and travel use. Shenzhen Huruishop Electronic Co., Ltd. is located in Huqiangbei, Shenzhen's established electronics district, suggesting access to component supply chains and refurbishment channels. Buyers must confirm MOQ, pricing, lead times, warranty terms, and actual safety certification status (CE, UL, or CCC marks) directly with the supplier, as specific figures and valid certificate numbers are not provided in the source data.

Shenzhen Huruishop Electronic Co., Ltd. is based in Huqiangbei, Shenzhen, Guangdong province, China (postal code 530231), within one of the world's densest electronics component and wholesale markets. The supplier carries an imported tier designation and harbor trust tier, with a 0.00% response rate and zero recorded average response hours. This profile suggests either a newly listed entity, limited platform engagement, or a trading company operating through multiple storefronts rather than direct manufacturing.

The company's listed specialisation is power adapters for Dell systems, though no factory ownership, production capacity, engineering staff size, or OEM/ODM client list is provided. The source description references ISO and CE certifications without certificate numbers, accredited body, or scope of accreditation. Buyers should not assume manufacturing origin, and should verify whether the supplier designs and assembles products in-house or sources from third-party factories in Shenzhen's peripheral industrial zones. No revenue figure, year of establishment, or export license details are stated in the source data.
