Can I use an HP or Dell adapter/charger on my Lenovo Ideapad Y550 laptop?
The adapters look almost the same but cost much less, will I be able to use it to charge my Lenovo?

Only  if the laptop requires the same voltage and current as the charger can  output, or even higher current. Tho that is not usually recommended.

Hello  L2theL:  No, absolutely not. I would never in my life recommend this to any  individual for whatever reason. First, they are different brands for a  reason. Its like using a energizer battery in place of a car battery.  Second, the voltage, amperage, and connector tip is very different in  most cases. Third, to save money on a charger and risk the possibility  of damaging your laptop is definitely not worth it.  I would just recommend you get a new charger, one for your laptop  specifically.  If you are worried about pricing and quality, you shouldn't. Many great  online stores like Topmic have great services and durable products so  you don't need to worry. You can find them via Google Search. They have  something called lifetime warranty, which means if it breaks, any time,  they replace it for free. It breaks again? Another free replacement.  Over and over for a lifetime. They also include free shipping and 30 day  full refund which is nice.  I would never suggest you use another charger brand, especially if they  just "look" alike for your laptop. Risking the possibility of starting a  fire or frying your motherboard is never a good thought.  Best of luck.
