Question 1

Can you also plug in it a laptop and cell phone/tablets, or is it only for appliances?

Accepted Answer

Yes, it's also ok for laptop and cell phone, while, I do not think you need to use it, as in my opinion, it's 100V-240V, you could double check  your manual.

Question 2

Will the 1600 watts converter work for maestri staple gun 1200 watts=(120vx10amps) in sweden? need to convert from us: 120v,60hz to sweden: 230v, 50hz

Accepted Answer

Dear, your staple gun is 120V required, right?  Then yes, it's ok, but the frequency is no changing, as UMI product is voltage converter only.

Question 3

Does it convert 50hz to60hz

Accepted Answer

Hello. The UMI step down voltage 220v to 110v converter can work on both frequencies. It is not a double conversion device. The voltage converter will put out the same Hz as you put in.

A transformer changes the voltage, not the frequency of the current supplied by the mains. The "mains" is the public supply of electricity. Some systems use 50 hertz frequency, others 60 hertz. Some appliances are designed to function on both frequencies but either exclusively on 110-120 volts or exclusively on 220-240 volts. Some work on both frequencies and both types of voltage. Almost all of appliances work on both frequencies. That's why transforming voltage is sufficient for most appliances. If in doubt, check the frequency of the mains and see if it is within the specifications of the appliance. If it says 50 Hz to 60 Hz, That would be OK.

Any questions with our products or step up step down voltage converter please feel free to contact us. Thanks for your trust and support!

Question 4

Does this work for smart and timed devices? Such as a rice cooker or a slow cooker with an automatic timer?

Accepted Answer

Yes, of course it's ok, just making sure the devices need 110V and power consumption is within the converter's capacity.
