Hi I have a Clevo W860cu and I am going to Hong Kong, however I have 5amps 250v power adapter and my laptop power cable is 7amps with 125v and 150w 240v psu. Will it cause my laptop to explode or I need buy a more powerful adapter ?
Sorry... its a bit confusing. 5amps at 250v power adaptor is quite big even for a gaming laptop.
Laptops usually comes with its own AC-DC power adapter. These power adapters are usually auto-volt & should be usable in any country ( by the way, Hong Kong is 220V 50Hz). If you will use the same power adaptor that came with your laptop when you purchases it, it should not explode.
Please check the markings on the power adaptor & see if it supports 220V. In this case, you should be okay.
Depending on where you are coming from, you may need an adapter. The Hongkong AC socket is like in Malaysia, Singapore & the UK.
