As you can already see in the title, I'm searching for an (alternative) power adapter which is compatible to my Lenovo IdeaPad Flex 15.
My old power supply was the original included one, when I brought the notebook. Unfortunately, I've lost my old one and need a replacement. I've asked the Lenovo support, if it is possible to get a new one that matches my device. Yes it was, but I found out it was too expensive.
After a short search I saw these https://www.google.co.uk/?gws_rd=ssl#q=universal+notebook+adapter universal notebook adapter. The price and the idea captured my interest, so I decide that one of these should be my new power supply. However, because of the huge selection and options, I don't know what would work for me. I must also say that I don't have any knowledge about power supplies.
This will become my main power supply, so it should not be for occasional use. Also it should be very versatile to use, because I have many other different laptops and traveling around the world, so a flexible power input and output would be nice.
What power adapter would you recommend? (I live in Germany)
