can any US household electrical device/equipment be made to work in asia..

There are frequency differences as well as voltage differences.  Much of the world runs on 50 Hz as opposed to the US 60 Hz power.

Now there are some items to which this doesn't make any difference, but there are also some to which it is critical.  

If you can give us specific items, we can comment on them.  For example, it makes no sense to take a US hair dryer to a 220V country.  These burn up the little transformers for small items such as radios - the current pull is way too high.  Likewise, taking a motor-driven clock to a 50 Hz country will make it run slow by 1/6.

thank you..
thinking of these 2 juicers

Don't know anything about that specific model, but perhaps one of the other experts does.

thanks kindly..
