Specially engineered for Chinese students, expats, and travelers in North America, the Shunhong (Copper) SHJY-500VA (TN5002) seamlessly converts American 110V mains power into dual synchronized 220V Chinese standard outputs. Housing a 100% pure copper toroidal core inside a sleek white flame-retardant shell, it sits neatly on desks or vanity counters to power imported personal care tools and compact countertop electronics.
Dual Isolated 220V Ports: Run Two Domestic Appliances in USA
Traditional step-up transformers offer only a single outlet, forcing users to buy multiple converters or frequently swap plugs. The (copper)SHJY-500VA features dual isolated secondary windings feeding left and right standard China 5-hole sockets. Students and expats can simultaneously power styling tools, electric shavers, or desk gadgets with uncompromised voltage stability.
100% Pure Copper Toroidal Core: Unrivaled Efficiency & Cool Operation
Unlike aluminum-wound transformers prone to resistive voltage sag and excessive heat, this model is wound with premium oxygen-free pure copper wire around a cold-rolled silicon steel ring. Electrical resistance is drastically reduced, delivering over 92% conversion efficiency, zero voltage drop under load, and steady filtration of US grid fluctuations to safeguard sensitive electronics.
One-Touch Instant Voltage Boost: Zero Learning Curve for All Ages
Equipped with an ergonomic physical rocker switch and an intuitive power LED, the unit activates instantly upon connection to US 110V mains without warm-up lag or configuration. Eliminates the need to repeatedly plug and unplug cords, reducing arc sparking and mechanical cord fatigue.
8-Fold Linked Full-Domain Safety: Engineered for Unattended Dorms
A comprehensive safety ecosystem safeguards your home: millisecond-grade short-circuit cutoff, internal thermal overload sensors, electromagnetic radiation suppression, exterior leakage isolation, V-0 self-extinguishing housing, perimeter convection vents, non-slip base, and automatic fault-clearing power restoration.
Acoustically Silent (≤20dB) & Airline Baggage Approved
Precision toroidal manufacturing eliminates 60Hz electromagnetic buzzing, keeping noise levels under 20dB for peaceful sleep. Free of permanent magnets and hazardous liquids, the unit complies with FAA, TSA, and international aviation carry-on and checked luggage standards.
Factory Direct OEM/ODM Customization & Stable Delivery
Originating from our factory established in 1987 with FCC, RoHS, CQC, and CE certifications, we offer customized input plugs (UK, EU, AU) and non-standard output voltages. Stable supply chain guarantees rapid order fulfillment for cross-border e-commerce and bulk procurement.

How to Use This Voltage Converter
Frequently Asked Questions About Voltage Converters
Why is the (copper)SHJY-2000VA essential for Chinese rice cookers and blenders in America?
Domestic rice cookers and high-speed blenders draw 800W to 1500W and feature complex electronic microprocessors that monitor input voltage. Aluminum transformers experience severe voltage drop under these loads, causing cooker error codes (e.g., E01/E02) or blending motors to stall. The 100% pure copper core in (copper)SHJY-2000VA holds a rock-solid 220V to cook rice and blend thoroughly.
Will running a 1400W electric kettle trip the circuit breaker in my US rental apartment?
No, provided it is plugged into a standard 15A or 20A 110V branch circuit in your American apartment. The unit has an ultra-low no-load current (~10mA) and features an integrated 1.5mm² grounded cable that absorbs inrush surges without tripping the household breaker.
Is the 6.3kg unit quiet enough to power a home oxygen concentrator in an elderly person’s bedroom?
Yes, remarkably quiet. The 6.3kg weight is due to dense pure copper windings and cold-rolled silicon steel, which eliminate 60Hz magnetic humming. Operating noise is strictly under 20dB, ensuring uninterrupted restful sleep for elderly family members.
