Instapark ITU-1000 Series Heavy-Duty AC 110/220V Step Up/Down Voltage Transformer/Converter with US Standard, Universal, German/French Schuko AC Outlets - 1,000 Watt

This is a great little device. I bought a donut machine that took 220v, didn't even realize it until it was too late to change my mind. So, I was looking for alternatives for powering it and came across this little gem. It was pretty inexpensive and had some good reviews, so I decided to try it. Wow - it's great! It's quiet, no noise or smell (which some people in reviews of other products had mentioned) and I've had no problems. I've run my 1800 watt 220v donut machine off this converter for about two hours now, an hour at a time, and had no issues whatsoever. Addition - over a year later, I've used it many times, it's always been flawless. Nice product!

Great product. I connected my 700watts euro standard receiver to it. The transformer is on 24/7, no heat (not even warm) no noise, no smell. Very happy about the choice I made.

It works , you just really have to watch out not to plug anything in with high watts as it will blow the fuse, it did that twice with me, so it’s great as long as you use it for low watt . A hairdryer will blow the fuse 😁

Received it yesterday. However, at the initial turn-on "w/o any load", it opened the circuit-breaker in the basement. I turned the switch off, and closed the circuit breaker, and then turned it on again. Then it didn't open the circuit breaker. And I could plug a device into it. It seems currently working fine without noticeable noise or heat. However, I asked for the replacement for the initial issue. Now I give three stars for the problem. This review may be updated after receiving new product. Update: I changed it to five stars for their response and services and the product operating quality -- no noticeable noise or heat.

Works fine but sadly it's discontinued.

Absolitely perfect. Comes with adapter for 220v-240v countries. Tried it and this transformer has charging boths. Both 110 and 220 can be used at the same time and it is absolutely silent. No unnecessary buzzing annoying noise like the others.

Works well. Sturdy. Sometimes makes a little bit of constant noise when in silence.

We have a nice espresso machine, toaster, etc that we didn't want to have to replace when moving to the US. I've been using this converter for close to two years. I try to plug/unplug while it's off, but I've forgotten plenty of times without it causing any issues. It is very heavy and bulky, but that's what you're signing up for when you need a product like this. For me, it's worth a bit of lost counterspace to keep the appliances we love.
