Best Voltage Converter?

11/14/2017 11:38 PM

I recently purchased a Rockstone Power 3000w Converter Step up/step down and promptly returned it. The thing had a horrible, toxic smell barely out of the box and stunk up the whole house. I didn't even use it. I've been looking at many different 3000w converters but after reading reviews seems many have this stink problem which brought me to this thread. I need this converter for a high sheer emulsifying mixer that I am using to make cosmetic products. My mixer is 220v from China and I need to step it down to 110v.

Before purchasing another stinky converter, I'm wondering if anyone has suggestions on a good 3000w converter that doesn't stink and won't malfunction (with proper treatment).

Why not just hook it up to 220v....? you might already have a 230volt plug somewhere in the house....you just need an electrician to check it out....and convert the plug type...

With regard to the necessity of using a voltage converter, i have consulted with an engineer who oversees maintenance in my apartment building. Conclusion: Converter is necessary. Thank you for your thoughts. :-)

Anytime you depend on things with coils such as transformers (converters) you will indeed get some "horrible, toxic smells" from it until it finishes its burn-in time, where the varnishes fully cure around the coil windings and core laminations. My best suggestion is, do not have the converter in the same room while manufacturing perfume while the converter is going through its final burn-in.

You also did not mention what voltage frequency this converter was meant to run on, 50 or 60 Hz?

It cost too much money for manufacturers to do a complete burn-in on every unit. They usually bench test them for a given amount of time, (15 minutes or less) for proper operation and no shorts circuits. That's not enough time for the varnishes to fully cure. And remember, most manufacturers have approx. 90% yield rate, so 1 out of 10 could be defective.

If it came from a Chinese manufacturer, it could be 9 out of 10 .

One thing we need to know is if this machine is single-phase versus three-phase.

Do you have any 220v appliances in the house, such as clothes dryer, stove, water heater, air conditioner? The 220v double pole breakers are easy to spot in your electric panel...

If so that means you have 220v available and just need an additional circuit run...You can convert a receptacle that is convenient to your workspace from 110v to 220v....this appliance only draws 2.5 amps

15a....your plug type and receptacle will look like this...

Are you doing this cosmetic blending at home? Isn't that just slightly illegal in most countries due to Food & Cosmetic Grade Purity Regulations?

Sounds like your thinking is totally backwards. Just because you do not have 220 V circuit at hand, does not mean you cannot have one in the future. Hire an electrician, or better yet, stop doing this at home.

According to FDA it’s not illegal as long as the process and final product is unadulterated. Ph testing and antimocrobial testing before finalizing product is essential.

Just keep the stinky transformer outside, in your garden, terrace or roof. The cables you need to get in your house do not need to be thicker than 20AWG.

Moreover, the stinky smell goes away after some hours. You are making too big of a deal about it.

The Rock stone inverter is actually made by a division of Bright star. A Chinese manufacturer of low quality Electronic devices in Guangdong China

The horrible smell quoted is likely the result of toxic varnish formulation and toxic degassing of dielectric paste

They are both junk, you get what you pay for.

As for the making of cosmetics at home, Asian television is replete with all sorts of homemade witches brews of long life snake oil remedies.

A day of reckoning is coming when Thor's ( FDA) mighty hammer comes down on these illegal " chop shops ".

Just out of interest,,,

Have you heard the latest news on those spinners every kid in your neighborhood is playing with ?

Seems to be, all of the ones made in China ( and they are all made in China ) are all made with toxic levels of lead mixed in with the plastic.

Who would of guessed ?
