Pyle Step Up and Down Converter - 500 Watt Voltage Converter Transformer w/ USB Charging Port, UK Power Adapter, AC 110 / 120 to 220 / 240 Volt Vice Versa, 110V/120V/220V/240V Input Voltage

I bought it to use electronic devices that I bought from other countries.It was delivered perfectly in a very nice package.I had a hard time carrying because it is very heavy.It works smoothly without any problems.Yes there are some noice but its not much to bother me.Size is not small.It is really versatile product for me because I have many devices from another countries.

I had 220V weigh scale purchased from India. I was looking for safe and reliable product. As it was related to electricity. After performing deep search and reading lots of review. I concluded to buy PYLE product. Product is nicely built and anyone can operate even who doesn't have enough technical knowledge. When I turn on the voltage convertor. The first thing impressed me is product is silent. No humming sound of transformer at all. That means transformer is built perfectly and no worry of over heating the product and no power losses. And this product can be used anywhere in the world. Input voltage selector link is already set to 110V US voltage. So no need to worry about it if you are in the US.

Excellent I plan to buy 3 more soon

Purchased 2 of these and they functioned well right from the start. Easy to setup and no real issues with their function. The only problem I had was an extremely strong smell of electronics (much more than routine off gassing). I placed both in an outside window with a fan blowing through the side vents and in a few days the smell had reduced enough to be unnoticeable unless you were smelling it directly. After that it continued to reduce and no long has a detectable odor.

I was first very happy to find this, and it was from Pyle. Anyone who does much with audio has heard of Pyle. So I though - this is safe to buy. And it has some great features like the tap changing. But when it arrived, I was very disappointed. The initial impression is that it feels well built, except I could not find any UL mark / label anywhere. UL (and ETL) means that a product has been verified to be safe from shock and fire. The reason for no UL was evident after I decided to open it up. The protection fuse is an improper instrumentation size fuse (5mm x 20mm) and not a full sized AGC (1.25 inch) or equivalent rated fuse/breaker. And it blew while I was using this - due to the transformer's own inrush current. No load was attached! Just turned it on. Pop. The fuse is not slow blow for the transformer inrush. I was going to modify the fuse and holder to make it usable and then noticed that the transformer is not varnished. Every transformer shop I have ever worked with said that varnish is necessary to complete the insulation of the windings. So - project ended. I don't want this plugged into the utility continuously under the desk.

Works as described. I've been using it every day for 3-4 hours a day and I've had no issues at all. The description says it's portable and it is on the small side, but it's heavy. I would not recommend if you're traveling, if you're setting on a permanent place then I'll recommend this 100% great value for the money. I did noticed it did not come with a replacement fuse (not a big deal) aside from that, i have no complaints.

I bought an amplifier online from Deutschland. When it arrived I realized I needed something to change the 110 v from the wall mains to something the amp could use. With the Pyle PVTC320U I was able to step up the voltage with no problem. I was worried it would make the amp sound bad, but there is no hum that I can notice. Construction feels sturdy and quality.

Everything about the build-quality is great, especially for a Chinese-made transformer. I opened this unit up (do not attempt unless you're qualified and / or comfortable around electricity) and discovered quality connections and wiring, as well as actual machine screws holding everything together (as opposed to wood screws common on lower-end units). Additionally, the transformer was clearly marked with a "QC PASSED" sticker on the back. Though, take Chinese "quality-control" with a grain of salt. However, upon testing with a multimeter, it's apparent that the incoming live (L) and neutral (N) wires are REVERSED. This is dangerous for a number of reasons. Most importantly, it means that all properly wired appliances plugged into EITHER the 110 or 220 outputs of this unit will have a LIVE voltage present on the neutral wire. Additionally, the 220 volt outlet will be supplying 220 volt split-phase power as opposed to 220 volt line-to-neutral when used in the step-up configuration. This means that BOTH the live and neutral side are carrying 110 volts relative to ground. So while there is still 220 present between the two, the voltages are reversed. This issue can be solved by cutting off the given plug and wiring in your own plug and switching the live and neutral with one another. Be aware, however, that this is with a United States type (NEMA 5-15P) plug. Also, be sure to check your output voltages relative to the incoming power to ensure how your transformer has been wired. It may be that only some of these units are wired incorrectly. So always check for yourself before plugging things in! Good luck folks and have a great day!

Works good :D happy with product .. have lot of items which run on 110v from North America also has plug for 220v :D ..

Hasta el momento funciona muy bien para mi Elíptica, genial que no genere ruido

I just received the transformer. After installing it to power up my subwoofer I noticed the hum from the transformer (which is located in my entertainment console) is perceptible in my living room. If you don’t mind that the transformer is easy to set up. My only complaint is that I did not receive the 2 spare fuses as stated

Buen desempeño

One of the appliances bought from US is not working using this transformer.
