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

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.

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

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.

Does it convert 50hz to60hz

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!

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

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

US to Asia - Dyson Airwrap

I didn't expect for the transformer itself to be so heavy, but omgggg this has been a lifesaver as someone who got a Dyson Airwrap as a gift in the states. I live in SEA so I was scared of plugging this right in. This transformer has been a lifesaver! Been styling my hair with no problems from the airwrap and the transformer itself. Definitely worth the purchase!

Satisfied

Using the device to power a bidet imported from Japan. It's on 24/7 and works well. The passive power consumption with the bidet plugged in is around 6w. The device itself is extremely heavy and feels well built. Operating noise and heat are very low. The only downside is the high price, which is still in line with similar devices.
