I need a laptop power supply

We sell generic laptop power supplies (with various plug sizes to suit popular laptops).

We do not sell OEM power supplies, and have no database to cross-reference specifically what your laptop needs, sorry.

Does your laptop accept power via USB-C? If so, just pick a USB-C power supply (such as MP3344 or MP3465) that has a higher rating than the watts your laptop requires.

Our product pages for the barrel-plug power supplies lists the dimensions of the various plugs included, so if you can visit your laptop maker's website and find your laptop, you should be able to confirm the plug dimensions are the same as one of our plugs.

Otherwise, it's best if you pay your local store a visit with your laptop, and try the different size plugs included, so you can make sure that one of the plugs is going to fit. The staff will be happy to assist.
