Will the wrong laptop charger break my computer?

Given the investment many people make into their laptop, which can often be over £1000, people are right to be cautious what laptop charger to use with their machine.Here at Laptop Power UK, we are often asked whether using the wrong laptop adapter can break your laptop.The answer to this question, you will be glad to hear is usually no.

Laptops draw current from the laptop charger, the laptop adapter doesn’t push current into the laptop.Therefore if you use a laptop ac adapter with a higher wattage than required by the laptop, the laptop will simply draw the current it requires and absolutely no damage will be done.Clearly purchasing high wattage laptop chargers can be expensive, therefore we always try to supply customers with exactly the same laptop power cable as suggested by the laptop manufacturer.

If you use a lower wattage laptop charger than specified underneath your laptop, again no damage will be done to your laptop.However, unfortunately, because the laptop charger in this case is not powerful enough to run the given laptop, over a period of a couple of months, it is likely that the laptop battery charger will burn out and you will need to buy a new one.

Come to Laptop Power UK and let our sales team guide you through the buying process, or alternatively use the search functions on our website homepage ( and you can’t but help get the right laptop power cable for you laptop – in record time!
