41-piece DC adapter kit for laptops

This kit supplies 41 interchangeable DC connector tips built around a 5.5 x 2.1 mm female base. It converts a single universal AC adapter or external battery into a multi-brand charging solution for notebook repair, parts replacement or travel power needs.

Suits technicians and travellers carrying one

The assortment covers 14 tip types in Group A and 10 in Group B, plus additional sizes, matching many Lenovo ThinkPad, Dell, HP, Toshiba, ASUS, Acer, Samsung, Sony and other notebooks. Buyers who need proprietary magnetic tips, USB-C Power Delivery connectors or high-wattage server plugs will not find them here.

5.5 x 2.1 mm female base accepts 41 tip variations

The base diameter is fixed at 5.5 mm outer and 2.1 mm inner, and the included tips range from 3.5 x 1.35 mm up to 7.9 x 5.5 mm with centre-pin sizes of 1.1 mm, 1.4 mm and 3.0 mm. If the source adapter does not terminate in a 5.5 x 2.1 mm male plug, the kit cannot be used.

Questions about this item

How do I connect the 5.5 x 2.1 mm female base to my laptop, and which tip do I pick?

Slide the chosen tip onto the 5.5 x 2.1 mm female base until it clicks, then insert into the laptop port. Match the tip dimensions — such as 7.9 x 5.5 mm for Lenovo ThinkPad or 4.5 x 3.0 mm for HP — to your device’s original connector.

Will any of the 41 tips wear out or need replacing over time?

The tips are passive metal connectors with no moving parts, so they do not degrade under normal use. Only physical damage — bent pins or cracked housings — would require swapping an individual tip from the kit.

What stops me from using these adapters continuously on a high-draw device?

The kit contains only connector tips rated for low-voltage DC applications such as routers, speakers and notebooks. It has no internal regulation or current-limiting circuitry, so the power supply’s own limits determine the maximum sustained load.
