Query: It works!

I bought this item to charge some of my products that work only on 220-240V.Pros:- speedy delivery- good packaging- universal connector in the front of the unit- option to select input voltage setting at the back of the unit- on / off switch- additional universal plug / socket adapter- additional fuse in the boxCons:- gives out a funny smell (not a burning smell but could be the lubrication used in the unit....not sure)Have used it only to successfully charge my items offline; have not tried to use my items whilst it is connected to this product.
