usbroway 38 PCS 5.5 mm x 2.1 mm DC Adapter Tips Connector Kit

38-piece DC tip kit for 5.5 mm barrel connectors

This set contains thirty-eight interchangeable tips that fit a standard 5.5 mm by 2.1 mm female base. Each tip plugs onto a matching male connector found on universal AC adapters or portable power banks. The assortment is intended for technicians and travellers who service multiple laptop brands with a single charger. It does not suit devices that use proprietary or non-standard barrel sizes.

Consistent fit across extended charging sessions

The tips are designed to maintain a secure mechanical connection while a laptop draws power continuously from an external battery or mains adapter. No active electronics are present, so behaviour under load is limited to the physical contact integrity of each barrel interface. Users who need regulated voltage conversion or current limiting must provide those functions elsewhere in their power chain. The kit itself adds no thermal or electrical regulation.

Limited to 5.5 mm x 2.1 mm male host connectors

Compatibility ends where the host connector deviates from the 5.5 mm outer and 2.1 mm inner diameter standard. The supplier notes specific incompatibilities with certain Dell, ASUS, MacBook and Xiaomi models that use different jack dimensions or pin configurations. Buyers who need tips for USB-C Power Delivery, slim-tip Lenovo, or other proprietary interfaces must source a different kit. No adapter for alternative barrel standards is included.
