LiteFuze 300 Watt Step Up/Step Down Travel Voltage Converter, 220/110v to 110/220v converter with Type E/F Plug - Compatible with Hair Straightener, Camera, Laptop & More

300 Watt Step Up/Step Down Travel Voltage Converter, 220/110v is very nice and usedful transformer for house use. Some what heavy to travel with it. We bought it for house use.

I bought 2 of these to use with my musical equipment in Europe. After a lot of research these were supposed to be the best for what I needed. When I first plugged them in there was a hum and they began to smoke. I was so disappointed with this product. I am in Europe for another month and cannot find anywhere on Amazon how to return them from here. I went to the Amazon Netherlands site as was described to do. It recognized my account but showed that I had no orders…ever.

I received the item exactly as advertised, 100% satisfied with the seller. An international shipment fulfilled by Amazon.com to my country and received faster than estimated date! Amazon.com always provide excellent service direct to my homeland address outside the USA, many Thanks to their shipping! Back to the item, I bought it to be used in Malaysia, which the supply AC is 240V-50Hz. It has done the functionality as good as described, NO abnormal heat, NO noise/ vibration or hum effect and NO weird smell during its operation, excellent! The cover casing well-built, (not looks like cheap china), fitted with fused, neon-illuminated power switch and AC input selector switch (110/230V-AC). How ever a little drawback on safety features- NO internal cover plate at the output socket to hide/close the opening of metal parts when not plugged in, which barely seen. Could be dangerous risk of AC shock to children around, can easily slot their tiny finger into that opening. Operational Test: I had done simple test/measurement using a FLUKE 112 (TRUE RMS multi-meter) and found the output voltage is sharply at 120V after connecting to my home 240V, and it goes up to 124V when sometimes the input hits up to 249V. Very good, stable step down regulation. BUT.. one thing that not mentioned clearly is the AC frequency, means the HZ value! This transformer just converting the AC voltage BUT did NOT do anything to AC Hertz. I think that would gives effect when using with appliances that not an AC Hz tolerance. The phase shifts of sinusoidal AC will produce different power factor. Unless the appliances connected to this transformer can tolerates witihin 60-50hz variation. For example, If I plugged in this transformer to my home AC outlet of 240V-50Hz, the output of the LiteFuze would be 120V-50Hz, it didn't replicating the true USA 60Hz AC. Meant no change at AC frequency, hence that US AC adapter connected to LiteFuze will have the same Hz of frequency, which did not converting 50hz to 60hz. I don't know, whether that would be any voltage fluctuates or power factor issue. Another test, I did with the Black&Decker Dustbuster Cordless vacuum as it comes with AC adapter for North America electrical specification, rated as 110V-60Hz only.(-no tolerance of frequencies as usual worldwide AC adapter)) to step down voltage at 17V-AC (another unusual specs, why B&D applying AC voltage instead of clean DC to charge the internal battery). Then, when plugged the adapter to LiteFuze, the measured voltage output at the terminal jack hits up to 22V-AC, which brought 5 volts higher than specified in the product manual. I did not sure whether this wrong caused by LiteFuze converter nature behavior or the B&D ac charger turned wrong, but for sure enough to heat up/ failure to the electronics charging circuit inside the portable vacuum. I just came out with the hypothesis after done a simple measurement (FLUKE 112), but just to analyze what actually happen when operating this converter. Besides that, this is a good quality converter.

I bought this with the 2 pin European adapter and it didn't fit a single outlet in any of 4 Italian hotels. I had to buy an adapter in Italy. I was told the pins are an old style and are slightly too large for modern outlets. Otherwise it performed well with the adapter and ran my laptop.

This voltage converter is just what I needed. I bought it for my travel to the UK and it works perfectly. There is no noise when using the converter and it does not overheat. The unit is light enought that you can put it in your suitcase. Keep in mind that this transformer will only step up/down the voltage and will not change the utility frequency. If you are going to use an electronics device that used the frequency for a timing source (i.e. AC alarm clock), you will not be getting the accurate timing.

Bought this thinking I could use my Andis razor in Dubai. Plugged it in and it started overheating and my razor started smoking. Both were toast after about 20 seconds. Had to buy a new razor and returned the converter. Paid $30.00 for the converter but they only refunded $20.00. Don't buy this if you plan on using equipment with a motor it most likely won't work. I'd suggest biting the bullet and purchasing whatever equipment you need in the country you're visiting/moving to it'll be cheaper in the long run.

I bought this because I live in a country which uses a 240V power supply and I wanted to buy a printer on Amazon that ran on 110V power supply. So I got this and it works like a charm. It's been on continuously, 24 hours a day, for several months now and I've had no issues whatsoever. No noise, and stays cool to the touch.

Great product. thanks,

Used in Germany for my various electric devices (electric toothbrush, waterpik...) Pros: No noise due to fans. Has a switch. Cons: Larger than expected but not too crazy.

I have a Magic Bullet blender which is American version and this was a gift given to me.So I bought LITE FUSE Voltage converter and it works well.It is almost a year and It works well.

Just blown Not for long lasting

It turns on but didn't seem to have the power to charge or anything. I'm not sure why, but I'm no longer travelling so I don't need it.
