| Look at the 'wall wart' for all your devices. The black box that is on the cord. It should clearly state what it can and cannot support.
Most laptops are 110-220. I'd be suprised if yours was not. Many wall warts for mobile phones are 110-220. Those would just need a 'plug' converter ($1US anywhere in HK).
If the cord has no wall wart, look on the back of the device or in the manual to see what sort of input it can accept. If it just says 110, then you will need the 'brick' of a power convertor that looks like a transformer.
Laptop, blackberry, phone--I'd be shocked if any of those were just 110. I think all you will need is a plug convertor, not the power convertor.
But please check. You only get one chance if you mistakenly plug something in to something it should not be plugged into, along with a nice sizzle pop and occasionally a spark. |
