I bought it for charging my creative soundbar, which came with a cable but no charger. The specifications of the soundbar were 5V/2A. This charger has two outputs, one for 5V/1A and one for 5V/2.1A, so it seemed OK for use. Mine is black (i.e., it is the OTU-385B, B for black, while the one mentioned here is the OTU-385W, W for white), a bit bulky but aesthetically pleasing, and the OSIO logo lights up nicely when the charger is plugged in. I have had it for 1 month and I can say that it does its job. However... it literally burns, I have never felt a higher temperature in a charger, it's like it's boiling. Maybe the requirements of the soundbar are high in terms of current, although - as I mentioned before - the specifications of the charger match, resulting in it reaching its limits. Anyway, with this temperature it produces, I cannot recommend it, and I'm afraid it might break at any moment. In essence, I don't know how to rate it, and because it has been working correctly so far and has not shown any flaws yet, I give it 3 stars.

UPDATE 03/09/2019 - I bought another charger (HUAWEI) and I discovered that for the same use, you don't even notice a temperature increase. With the Osio charger, you can boil an egg! Therefore, I am changing the rating, and it goes from 3 stars to one. Choose something else, unless you want a heater for the winter!

It charges 2 devices simultaneously and quickly without overheating. It is convenient and stylish with an illuminated logo during charging. I think it is an excellent purchase and I highly recommend it!
