Edward Wong 5 The charger does the work nicely, I can charge my Macbook Pro, and 2 phones together.When connecting multiple devices to charger, it may have a short break in power output, but then everything will back to normal, it will be a bit hot (but not kind of burnt feeling) when full loading, which is expected, and given the size of the charger it's perfect to use during travels.1 star deducted just because I think as a product for traveling, it should come with adaptor to use in other countries as a best fit, and I also expect at least a cable to be included.Update: Just bought a USB meter, and test it with my fully discharged MacBook Pro (see picture), it really delivers 60W power.
