Universal DC Adapter Tips

This set provides interchangeable DC power tips sized at 5.5 mm outer diameter with 2.1 mm and 2.5 mm inner diameters. It connects compatible notebook computers, mobile power supplies and power banks to a matching power source. The kit suits users who need to replace a lost connector or adapt an existing supply for multiple devices. No certification is claimed for the components.

Sustained Load Behaviour

Under continuous use the passive connectors transmit current without active cooling or circuitry. Performance depends entirely on the host power supply and the cable gauge used in the installation. The tips are intended for low-voltage DC transfer within the limits of the connected equipment. Buyers requiring regulated voltage conversion or higher current capacity should look for an active adapter.
