Ezlaptopadapters.com delivered two laptop power supplies that were under powered. 90 watts instead of 180 watts that I ordered. Company said they would send a new specification label that would double the wattage for me to attach on the power supplies - which is illegal and unethical. The power supplies would blow or damage my computer or even injure me. I sent supplies back and never received a refund. This company has a US website but is based in China. Do not buy supplies from ezlaptopadapters or Laptoppartsstore. They make up labels for electronic equipment and this will damage your computer.
