Can a laptop run on a different brand charger? [duplicate]

Solution 1:

There are three things to check:

• Output voltage
• Output current
• Connector polarity

As long as the voltage and polarity match, it wont hurt your laptop. If the current is lower, either it will charge your laptop slower, or not at all. Possibly it might damage the charger, but I don't think so.

Solution 2:

If you don't want to pay 80+, you do not mention currency, but, you can probably get a duplicate on eBay for a lot less.

Anyway, that aside - the "other" charger has a lower output than what your laptop requires. If it fits, you will probably not do any damage - it may either not work or charge slower.

That being said, I would never advise using any adapter that was not an identical match. It just isn't worth the risk of damage. If 80+ is expensive, think how much a repair/new laptop would be!
