A:AnswerI'm currently living in Germany & I'm using this adaptor/converter to charge both my MacBook Air and my iPhone. It fits a 3 prong US plug as well as your standard ones. It's safe for other products too, because I also use it for my hair straightener and for my little portable battery.
A:AnswerNo it would not work for your espresso machine. As it is designed to do the opposite of what you need. It converts US plugs to international. You would need a converter that does International to US.
A:AnswerThis unit is suitable for 50-1875 watts, but it is intended for short periods. It may not stay active until the batteries are charged, unfortunately there are too many variables for me to give you a exact answer.
A:AnswerBecause the unit pulls additional power for the conversion process, it may be overloading the circuit breaker for that outlet. Try a outlet that doesn't have anything else on the circuit.
A:AnswerIf the light on the unit is not turning off to indicate it is supplying 120v when it is plugged into a 230V outlet, you will want to take this unit to Best Buy for review if within warranty period..
