Specially engineered for high-wattage imported US and Japanese appliances, the Shunhong (Copper) SHJY-2000VA (TN20001) provides precise step-down conversion from 220V power down to dedicated 110V (US) and 100V (Japan) heavy-duty outputs. Built with 100% pure copper toroidal windings inside a sleek white fire-resistant housing, it safely powers pressure cookers, heating blenders, espresso machines, and IH smart cookers without voltage sag or motor strain.
Dual-Port Bilateral 110V & 100V Heavy-Duty Output
The (copper)SHJY-2000VA provides two heavy-duty sockets on opposing flanks of the chassis. Both ports share high-capacity pure copper toroidal conversion but run on isolated distribution circuits, allowing you to connect an American blender and a Japanese IH rice cooker at the exact same time.
100% Pure Copper Toroidal Core
Constructed from high-purity oxygen-free pure copper wire tightly wound on a cold-rolled grain-oriented toroidal silicon steel core. Pure copper delivers minimal internal resistance, superior heat dissipation, and zero voltage drop during continuous cooking cycles, shielding delicate microcomputer chips.
One-Touch Rocker Switch & Clear LED
Features a heavy-duty physical switch paired with an illuminated indicator. Turn power on or off in a single click without having to repeatedly pull plugs in and out of wall receptacles, eliminating sparking, cord strain, and socket loosening.
Whisper-Quiet (<20dB) Natural Convective Cooling for Peaceful Living & Dining
Stereoscopic convective ventilation grids evacuate internal heat naturally without cooling fan noise. Operating noise is strictly kept below 20dB, ensuring open kitchen conversations and family dinners remain completely peaceful.
Thickened Flame-Retardant ABS Housing & 1.0mm² Power Cable: Resists Heat & Steam
Constructed from high-grade, fire-resistant ABS+PC engineering plastic that resists high heat, impact, and chemical stains. Paired with an integrated 1.2m molded power cable with 1.0mm² copper wiring for superior durability across long years of kitchen use.
37-Year Transformer Manufacturing Heritage with Full Certification & OEM Support
Manufactured under rigorous factory quality control since 1987. Each unit undergoes strict voltage calibration, full-load thermal testing, and 8-fold safety validation before shipment. Fully compliant with CE, RoHS, FCC, and CQC international standards.
Made of pure copper material

Compatible Devices & Applications
US 110V & Japanese 100V Smart IH Cookers, Blenders,
Air Fryers, Electric Kettles & Salon Dryers
Recommended Continuous Load Under 1600W
|
|
The (copper)SHJY-2000VA carries a 2000VA peak power rating. For safety and durability in daily continuous cooking (such as rice cooking or baking that lasts 30-60 minutes), the continuous appliance power must be kept below 1600W (standard 80% continuous duty rating). Appliances involving motor startup surges (like food blenders) or high heat cycles (like air fryers) require adequate safety headroom. If you plan to operate ultra-heavy kitchen appliances above 1600W (e.g. 2100W commercial induction woks or 2000W+ ovens), you must select the flagship (copper)SHJY-3000VA model. | |
How to Use This Voltage Converter
Frequently Asked Questions About Voltage Converters
How does pure copper core construction benefit high-wattage IH rice cookers and heating blenders?
High-power appliances like IH cookers draw fluctuating current during induction heating cycles. Pure copper toroidal windings feature superior electrical conductivity and thermal inertia, preventing voltage drops and ensuring that output voltages stay strictly within ±3% of 110V/100V. The pure copper shjy-2000va 220v to 110v 100v transformer protects sophisticated microcomputer chips.
What is the maximum continuous appliance wattage permitted on the (copper)SHJY-2000VA (Merchant SKU: TN20001)?
The maximum recommended continuous load is 1600W. Although the transformer handles 2000VA apparent power, maintaining continuous duty below 1600W (80% load rule) prevents overheating and ensures long lifespan. The copper shjy-2000va step down voltage converter dual outlet is the perfect companion for 800W-1600W kitchen appliances.
Can I connect two appliances simultaneously, such as a 1200W American blender on 110V and a 300W Japanese food warmer on 100V?
Yes, absolutely. The (copper)SHJY-2000VA features bilateral dual sockets designed for this exact scenario. With a combined wattage of 1500W (1200W + 300W), it sits comfortably beneath the 1600W continuous threshold. The 10a heavy duty pure copper step down converter 2000va delivers independent power across both sockets.
Does the 2000VA pure copper transformer generate disturbing electrical hum or heat when cooking for an hour?
No. Thanks to its tightly wound pure copper toroidal core and bilateral convective airflow channels, operating noise remains below 20dB. Even after prolonged cooking, thermal rise remains well within safety thresholds. The heavy duty pure copper 220v to 110v 100v step down converter ensures silent, cool operation.
