从China供应商批量进口90w Ultra Slim Universal Laptop Ac Adapter With

The 90w ultra slim universal laptop AC adapter from Shenzhen Gasage Technology Co., Ltd. accepts AC 100-240V at 1.8A across 50-60Hz mains frequency, with selectable DC output voltages at 14.5V, 15V, 16V, 16.5V, and 18.5V to service multiple laptop brands without dedicated OEM bricks. The ultra-slim form factor targets mobile professionals and institutional deployments where bag space and travel weight are operational constraints. This is a switch-mode power supply with automatic voltage selection or manual tip-switching, depending on the specific variant, rather than a fixed-voltage single-purpose adapter.

The input range covers global mains standards from 100V Japan to 240V UK/Europe, with the 1.8A maximum input current suggesting active power factor correction is either absent or minimal in this design. Output voltage selection at 14.5V-18.5V spans the conventional range for consumer and business laptops from major manufacturers, though the specific amperage at each voltage tier is not stated and determines actual wattage capability. The 90W headline rating likely refers to peak or continuous output at the highest voltage setting; efficiency at partial load and standby power consumption are unstated specifications that affect total cost of ownership in fleet deployments. Thermal design for slim enclosures typically relies on high-frequency switching and synchronous rectification to minimize dissipation volume, though this assumes quality magnetics and capacitor selection.

Primary buyers include educational institutions standardizing across mixed-device fleets, corporate IT procurement seeking reduced SKU complexity, and retail or e-commerce channels requiring universal compatibility claims for consumer resale. The adapter's slim profile suits airline travel and mobile workstation setups where traditional 90W bricks prove bulky. Import discussions with Shenzhen Gasage should address whether tips are included for all major laptop brands or sold separately, whether the voltage selection is automatic or manual, and what overload, overvoltage, and short-circuit protections are implemented. FOB Shenzhen or CIF terms are typical for consumer electronics from this region, though exact trade conditions require direct supplier confirmation.

Shenzhen Gasage Technology Co., Ltd. is located at 5F, 4 Block, Chuangye Industrial Park, Shenzhen 518000, Guangdong Province, positioning it within the primary electronics manufacturing and supply chain ecosystem of southern China. The supplier holds an imported tier classification and harbor trust status, indicating marketplace listing without advanced verification or guaranteed performance bonding. The response rate is recorded at 0.00% with zero average response hours, which signals potential challenges in pre-sales communication and necessitates that buyers establish clear contact protocols before order commitment. No factory size, annual turnover, employee count, or client references are disclosed in the available profile.

The source description references ISO and CE certifications without specifying standards, scope, or certificate numbers. Buyers should request the actual conformity documentation, including whether CE marks cover the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU) with applicable harmonized standards such as EN 60950-1 or EN 62368-1 for IT equipment safety. The description suggests FOB and CIF shipping terms are available, though minimum order quantities, lead times, and payment structures are not fixed in the listing and must be negotiated directly. Whether Shenzhen Gasage operates as a factory with in-house SMT and assembly capability, or functions as a design house or trading company outsourcing production, is not stated and affects quality control predictability.
