BESTEK Universal Travel Adapter 220V to 110V Voltage Converter with 6A 4-Port USB Charging and UK/AU/US/EU Worldwide Plug Adapter (Black)

Great, durable travel This is the third one purchased as a gift. It is sturdy, travels well and works even better. We have used ours for several years in Germany, France, Switzerland & Spain. We have traveled with a variety of converters and adapters over the years but have since gotten rid of those and travel only with this. I love the usb port but hope they also add usb-c ports. It does make a whirring sound but since we sleep with a sound machine on, it isn't noticeable.

We ordered this product in advance of a 2.5 week to New Zealand - a trip where we would be traveling all over both the North and South Islands. The product performed flawlessly. With 3 plug outlets and 4 USB ports, we had plenty of capacity at all times. Of importance when traveling internationally is the size of the product. The box for the product (with cords and converter pieces to deal with the demands of different countries) is only 6 x 3 x1.6 inches. The product is solidly built and the cord that goes in the wall is heavy duty. The ease of use is first rate. I saw another review, giving one star, of a purchaser (D. Rees) who said "It isn't easy to test this before such a trip....who has a foreign outlet here in the US?...not I." That purchaser reported the unit did not work at all. We had no trouble testing the unit before we left (we also traveled to New Zealand) as you do not need a foreign outlet to test it. You plug it into the wall here in the U.S. and turn it on. You then plug in a device to see if the charging function works. The only part of the product you cannot test in the U.S. is the single piece that plugs into the wall in the foreign country and that piece is a pass-through, i.e., it has no moving parts and, even if that part failed when you got to your foreign destination, you could replace it easily. Another one star reviewer complained that the "the cooling fan came on immediately." The fan operates continuously as part of its standard operation and is not a sign that something is wrong. That reviewer then reported something that was, in fact, a problem, i.e., "a loud pop came from the converter and sparks and smoke exited the converter." That reviewer (Mark) was careful to share exactly what was plugged into the converter so it was clear that he had not exceeded the converter's stated capacity. Perhaps the best guideline is to, one, buy the product in plenty of time to allow time to test the product well as we did, including load testing it with the devices you intend to us on the trip. That should reveal any defects with the product in a timely fashion, thereby allowing you time to resolve the problem with BESTEK.

--------------- 2018, 2 year update: I've now been using this for about 2 years. In addition to the previous Italy trip, I've used it overseas in China, Iceland, and Grand Cayman as well as numerous times locally. I had a little trouble in China finding an appropriately powered outlet to run a curling iron but did manage it. Otherwise this thing has kept chugging along with no issues. Phones, camera batteries, AA chargers, even hooked up a pico projector & raspberry pi game system and it handled everything! ----------------- Original review: I purchased this bad boy specifically for my trip to Italy in late September. Between my traveling partner and me, we had quite a few different devices that needed power at some point and this worked flawlessly I used the standard power input twice and stuck mainly to the 2amp USB ports while my traveling partner used a curling iron plus what I had. At no time did it disappoint. I also used this in the airport when people were hogging the power switches (plug this and the US adapter in and a few of you can charge at the same time) and the other person (plus a couple of others) were grateful for the extra spots. Yes, there is a fan onboard and it does make noise (less that a standard oscillating fan) but it's a small price to pay for consistent, reliable, and a variety of power options. I tried some Teflon wax lubricant and that helped for a day or two but wore off. Still, no big deal. I've tried a few different power adapters and they usually switch off/on as they run into spotty electricity but this kept up. Coincidentally a couple we met up with had the same thing (different brand but clearly the same unit) and loved theirs.

This is the third Bestek voltage converter we have purchased. When my wife saw the first one she absolutely had to have one too. Obviously we like the product. I have used it in Europe, Canada, and the US, and, as the saying goes, I wouldn't leave home without it. Even if you don't regularly travel outside North America the fact that this device provides three 110-120 VAC @ 60 Hz outlets, plus four 5 VDC USB power connections, regardless of input voltage, makes it very useful for domestic travel too. It can function as a small power strip for low wattage devices and charge 2 or 3 mobile devices simultaneously. Don't expect it to power an iron or a 1200+ watt hair dryer, but you can connect laptop and printer power supplies to the 110-120 V outlets and charge phones, tablets, or other mobile devices from the USB ports. With the Bestek converter you won't need individual chargers for your phone, your tablet, your e-book reader, your iPod, etc. All you need is compatible cables. I keep one on my desk when not traveling. Which brings me to my complaint. On returning from a recent trip I found that the converter was in my bag but the power cord was apparently still in Austria. I decided to order another converter with two-day shipping to meet immediate needs and replace the power cord with less urgency so I could have one permanently on my desk and one packed and ready for travel. Unfortunately, multiple inquiries to Bestek at the e-mail address provided asking about a new power cord have brought no response from the company. Apparently I have a spare converter in case something goes wrong with one of the other two.

Works well

I've used this voltage converter to charge my electric toothbrush and electronic appliances from the US (120V) here in Singapore (240V) for over a week. A green light comes on when it is running and sometimes a built-in fan in the converter runs as well. I can't tell about long-term reliability as I've only used it for a week.

Es un poco ruidoso al funcionar

The products generates a lot of hiss noise in the background just like a transformer. Whenever I record a video there is a huge background hiss noise from this piece of equipment
