Enterprise whatsapp account: +86-13690698363

Specially engineered for high-wattage culinary, personal care, and wellness equipment brought from China or 220V regions to Japan, the Shunhong (Copper) SHJY-2000VA (TN20004) effortlessly converts Japanese 100V mains into dual synchronized 220V Chinese standard outputs. Driven by a massive 100% pure copper toroidal core inside a sleek fire-retardant white casing, it safely runs rice cookers, heating blenders, and salon styling tools concurrently in Japanese homes.

1. Dual Isolated 220V Outputs: Double Culinary Efficiency in Japanese Rentals

Regular step-up converters feature only one outlet, making simultaneous cooking and daily living cumbersome. The (copper)SHJY-2000VA provides two isolated China standard 5-hole outlets, allowing you to run a domestic rice cooker alongside a soymilk maker or hair dryer without purchasing multiple converters in small Japanese rooms.

2. 100% Pure Copper Heavy Toroidal Core: Rock-Solid 10A Performance in Japan

Constructed with an oversized pure copper toroidal winding and cold-rolled silicon steel core. Copper offers vastly superior electrical conductivity over aluminum, keeping internal impedance minimal and preventing voltage drops during peak heating cycles. Ensures imported rice cookers and blenders run at full factory power even with 100V input.

3. One-Touch Instant Startup: Safe and Simple for Every Family Member

Designed with a robust tactile rocker switch and a glowing LED indicator. Plug into a Japanese 100V wall outlet and switch on for instant 220V transformation. Avoids repetitive wall-plug tugging and eliminates arc flash risks.

4. 8-Fold Full-Domain Protection: Robust Defense Against Grid Hazards in Japan

Engineered for long-duration operation with short-circuit disconnect, thermal overload cutoff, anti-EMI shielding, leakage lock, V-0 flame-retardant shell, dual convection vents, non-skid base, and automatic reset after anomalies clear, ensuring total peace of mind.

5. Whisper-Quiet Performance (≤20dB) & Airline Baggage Approved

Acoustically quiet design eliminates transformer hum, keeping ambient noise below 20dB. Free of permanent magnets and liquids, the unit fully meets international baggage transport regulations for overseas travel.

6. 37-Year Factory Authority & Global Voltage Customization

Manufactured by our certified plant established in 1987 with FCC, RoHS, CQC, and CE international certifications. Offers customized plugs (UK, EU, AU) and non-standard output specifications with guaranteed lead times.

Copper 2000VA transformer 100V to 220V professional application analysis

First, home appliances application overview
This copper 2000W transformer, with 100V to 220V voltage conversion function, which shows a wide range of applicability and excellent performance in home appliance applications. When users want to use European or Chinese appliances rated at 220V in a 100V rated voltage environment, this transformer becomes the ideal solution. Whether it is a rice cooker, hair dryer, wall-breaker, chef machine and other common appliances, as long as its power does not exceed 1350W (in order to ensure stable operation, the transformer should be used to reserve 30% of the power space), can be achieved through the voltage conversion of this converter, without the need to replace the appliance, you can achieve cross-border use.

Second, office appliances adaptation analysis
In the office environment, many devices such as small printers, copiers, scanners and other imported products may use 220V voltage. For such equipment, this transformer can ensure its stable operation under 220V voltage, effectively avoiding equipment damage or performance degradation due to voltage mismatch, thus enhancing office efficiency.

Third, the beauty salon industry applications
For curling irons, hair straighteners, facial steamers, beauty instruments and other European high-quality beauty salon equipment, its normal operation usually requires 220V voltage. Through this voltage converter, users can easily convert the local 100V voltage to the required 220V voltage, without travelling to Europe, you can enjoy the care effect of European high-quality beauty salon products.

Fourth, the application of medical equipment
In the field of medical equipment, some European imports of small home pressure gauge, small oxygen concentrator and other equipment may need 220V voltage support. This transformer can provide a stable 220V voltage output, to ensure the normal operation of medical equipment, to protect the health of users.

Ensuring the safe, stable and efficient operation of a power transformer is essential for protecting equipment, preventing malfunctions and safeguarding users. Therefore, in the process of using this copper 2000VA transformer 100V to 220V, it is essential to follow certain usage precautions and procedures.
Power transformer precautions for use
1, Waterproof and moistureproof
As this voltage converter is designed to pass through the internal core accessories, in order to achieve good heat dissipation, its shell is not a large area of waterproof treatment. Therefore, when in use should ensure that it is away from water sources to prevent water intrusion into the interior of the transformer, so as not to cause short circuits or other safety accidents.

2, Heat dissipation and ventilation
Voltage converter may produce a certain amount of heat during operation, which is a normal phenomenon. In order to maintain its normal operating temperature, should not block the transformer left and right sides of the cooling holes to ensure air circulation to help dissipate heat. If the power transformer is found to be abnormally hot or emit a burning odor during use, it should be stopped immediately and consult a professional.

3, Boot check
Before the first power-on use, the power transformer should be fully inspected. Ensure that the appearance of the machine is intact and undamaged, and the parts are fixed securely. At the same time, the first boot should pay attention to whether there is a strange noise or abnormalities, if any should be stopped immediately to check.
Power transformer use process:
1, check whether the appearance of the voltage converter is complete and spare parts are fixed;
2, connect the voltage converter input plug to the power supply with a voltage of 220V;
3, click the machine switch key, the voltage converter will be energized;
4, the 100V electrical appliances connected to the voltage converter, and then boot normal use can be.
