Description of 1000W Voltage Transformer Converter SEYAS with Auto Step Up and Step Down, 110-120V to 220-240V, Soft Start, Full Load Capability, 24/7 Continuous Run, Circuit Breaker Protection, U.S. Patent No. US9225259 B2

MULTIFUNCTIONAL & CONVENIENT - SEYAS transformer converter has 4 AC outputs, 2 US Standard Socket and 2 Universal Sockets for auto converting 110-120V to 220-240V or 220-240V to 110-120V (except the Big South African plug). Compact design for ease of transportation, the transformer can be used in most countries which voltage are 90V~125V or 180V~250V such as US, EUR, UK, JP and more. Noise reducing function included. ADVANCED AUTO STEP UP & STEP DOWN – With Automatic Voltage Conversion Technology (US Invention Patent No. US9225259 B2), manual selecting input voltage is no need any more. The transformer automatically recognizes the input voltage and converts to the corresponding voltage. So choosing incorrect voltage and damaging your appliances will not happen. PREMIUM QUALITY - CE, FCC, ROHS CERTIFIED - 24*7 constant work time with 100% loading capacity that superior to other converters. Resetable buttons on the back of the SEYAS transformer for restarting when auto shutoff as overcurrent. Just press the button and no need to take the machine apart to change fuse anymore. Built-in high-performance toroidal transformer with stable output and low consumption, makes it work efficiently and save more energy. SUPERIOR SAFETY - Soft start function to prevent an inrush current at the starting moment. Built-in 380 Joules surge protector inside is ideal for computer and household electronics. There are 2 input mini circuit breaker installed, once an overcurrent or short circuit happens, the machine will auto shutoff to prevent home circuit breaker from tripping off. Wonpro Upgraded Outlets ensure secured and firm grip for the appliance plug and would not get loose. CE FCC ROHS Certified. 3-Year manufacturer’s limited warranty. If you have any questions, please feel free to contact us.

Completely silent, constant, odorless and 24/7 no heat

I waited a few months before posting a review. But now I'm sure it's the device. First of all, the absence of extraneous smells and absolutely dead silence copes with its task perfectly, even when it is on 24/7. I'm using this to power a DAC bought in Europe (made for 230V) to run it on 110-115V in the US. Surprisingly, unlike other converters, this unit doesn't just double the input voltage. former. A 120V input will not convert to 240V. All other devices in a similar price range I've tried…

Pros
  • ADVANCED AUTO BOOSTER AND DROP - Automatic voltage conversion technology (US Patent No. US9225259 B2) eliminates the need for manual input voltage selection. The transformer automatically recognizes the input voltage and converts it into the appropriate voltage. This way it will not happen that you choose the wrong voltage and damage your devices.
Cons
  • Not sure

Everything works as advertised. Certified

I bought this for a new well pump installation that includes a 240v 3/4hp pump. and a digital timer head for a 120v water softener. I only had a 240v line available for the pump shed, so I ran the line to a regular two socket plug in the shed. The pigtail from the pump plugs straight into the outlet and gets 240V, and then I connected this device to a different plug to convert it to 120V. This unit has 2-120v outlets and I run the water softener from one and the second available for the lights…

Pros
  • CE FCC ROHS. 3 year limited manufacturer warranty. If you have any questions, please contact us.
Cons
  • Out of fashion

WARNING: Decent build quality but dangerous miswiring

I have recently purchased three transformers including this 1000w SEYAs unit. As an electrical engineer, I tested all three before connecting any devices to them. This SEYAS transformer was wired incorrectly: the input hot and neutral connections were reversed. Hot and neutral swap places at the exit when overtaking. Raising from 110V to 220V gives you 220V on two output lines, but each is 110V to ground, similar to a split-phase 220 in the US. To make matters worse, when you downshift from…

Pros
  • MULTIFUNCTIONAL AND PRACTICAL - SEYAS Transformer Converter has 4 AC outlets, 2 standard US outlets and 2 universal outlets to convert 110-120V to 220-240V or 220-240V 110 automatically -120V to convert (except large South African plug). Compact design for easy portability, the transformer can be used in most countries with voltage 90V~125V or 180V~250V, e.g. B. USA, Europe, UK, Japan and others. The noise reduction function is on.
Cons
  • Reliability

It's good, it's beautiful, it works.

Ordered to power my German 220v mini component hi-fi system which requires around 220w constant (minimum) and is powered by two sockets. I'm interested in the Seyas 500W because it has two international sockets, making an extension cord redundant, at least for the foreseeable future. The 500 watts of power seemed safe for my application and based on the good reviews (and yes I thought it was interesting that this item was patented) I decided to order it. Well what am I thinking? Firstly, the…

Pros
  • EXCELLENT SAFETY - Soft start function to avoid inrush current at the moment of start. The built-in 380 joules surge protection is ideal for computers and consumer electronics. Installed 2-input mini circuit breakers, when overcurrent or short circuit occurs, the machine will automatically turn off to prevent the house circuit breaker from tripping. The upgraded Wonpro sockets give the appliance plug a secure hold and prevent it from falling out.
Cons
  • Has problems
