Was concerned that no instruction came with the product -LRB- it is fairly self explanatory but I like product manuals just to be sure I understand things and the different adapter plugs were not clearly identified as to country of use
I also like the adapters plugs as I can connect each other to minimize space and keeping them together, my biggest complaint would have to be the fan being a bit noisy -LRB- especially when you are trying to sleep in a small hotel room -RRB-
I bought this device for a trip to Australia and New Zealand because my wife uses a CPAP machine and we needed to convert the foreign voltage to US voltage for that machine, It comes with plug adapters for several foreign countries
I find I rarely use the plugs now with so many items charging with USB but there's an internal cooling fan with a slight consistent fan/grind noise that's great to bleed street noise if close to your bed
easy to use and makes my new sound bar sound great, Highly recommend buying here rather than in a store and paying much much more for a product that is most likely inferior to this one as well
