As the ultimate high-capacity flagship of the pure copper step-up series, the Shunhong (Copper) SHJY-3000VA (TN30002) provides uncompromising voltage conversion from American 110V mains to dual synchronized 220V Chinese standard circuits. Anchored by an oversized 100% pure copper toroidal core inside an architectural fire-retardant white chassis, it easily powers high-draw Chinese culinary equipment, convection ovens, and heavy household appliances in North America.
Dual Synchronized 220V Outlets: Power Two Major Appliances in USA
Traditional single-outlet converters cannot handle multiple large appliances simultaneously. The (copper)SHJY-3000VA provides two isolated standard Chinese 5-hole sockets, allowing you to prepare an electric hot pot meal while brewing tea or running an air purifier concurrently without swapping plugs.
Flagship 100% Pure Copper Toroidal Core: 16A Sustained Power
Wound with heavy-duty pure copper magnet wire around an oversized cold-rolled silicon steel ring. Delivers exceptional electrical conductivity, low internal resistance, and minimal operating temperatures. Absorbs intense current spikes and prevents output voltage sag, keeping high-power heating elements running at full intensity.
One-Second Quick Boost: Intuitive & Safe Operation for All
Features a tactile physical rocker switch with an illuminated status LED. Plug into an American 110V receptacle and flip the switch for instant 220V power. No warm-up waiting, no configuration, and zero idle standby power draw.
8-Fold Full-Domain Safety Ecosystem: Complete Defense for USA Rentals
A multi-tier safety architecture includes rapid short-circuit disconnect, thermal temperature cutoff, anti-EMI radiation shielding, chassis leakage lock, V-0 flame-retardant body, natural convection cooling, anti-skid base, and automatic fault-clearing reset.
Whisper-Quiet (≤20dB) & Airline Checked Baggage Approved
Despite its powerful 9.2kg pure copper core, the closed toroidal magnetic design eliminates vibrational hum below 20dB. Free of magnets and liquid components, fully compliant with international aviation carry-on and luggage transport standards.
37-Year Factory Authority & Global Customization Support
Engineered by our certified manufacturing plant founded in 1987. Backed by FCC, RoHS, CQC, and CE international quality testing certifications. Custom plug styles (UK, EU, AU) and bespoke output specifications are supported with guaranteed production timelines.

Product Operate Guide
FAQ
Why do Chinese electric hot pots and steam ovens require the pure copper (copper)SHJY-3000VA in the US?
High-power Chinese culinary gear pulls 1500W to 2200W for extended cooking durations. Aluminum-wound converters suffer severe heat accumulation and internal resistance spikes, dropping output voltage below 200V and causing lukewarm broth, melted plastic shells, or sudden trip-outs. The (copper)SHJY-3000VA provides an industrial 16A pure copper core that holds steady 220V throughout a multi-hour dinner.
Can I plug two high-wattage kitchen appliances into the dual sockets simultaneously?
Yes, provided their combined running wattage remains under the recommended continuous limit of 2400W. The dual isolated secondary outputs ensure both outlets deliver stable 220V without mutual voltage drop or cross-interference.
What does the substantial 9.2kg weight signify regarding materials and safety?
Copper has a density of 8.96 g/cm³, more than triple that of aluminum (2.70 g/cm³). The 9.20 kg (20.28 lbs) net weight is physical evidence of an uncompromised 100% heavy pure copper coil and cold-rolled silicon steel core. It delivers durable industrial performance and avoids fake wattage ratings common in lightweight aluminum units.
