Enterprise whatsapp account: +86-13690698363

The SHJY-800VA (N8002) is an 800W step-up voltage converter engineered to step up 110V North American grid power to 220V for international appliances. Manufactured by Shunhong Transformer Works with full OEM/ODM capabilities, it delivers robust electrical performance and long-term thermal stability.

Dual Bilateral 220V Outlets for Concurrent Two-Device Operation

Symmetrically placed independent 220V sockets on the left and right sides operate simultaneously with separate electrical channels. Run two 220V kitchen or personal care appliances at the same time without cross-voltage drop or the expense of buying multiple converters.

Precision Toroidal Aluminum Winding with Cold-Rolled Silicon Core

Features a precision-wound toroidal aluminum coil integrated with high-permeability cold-rolled silicon steel. Provides ultra-low internal resistance, minimal conversion loss, and clean electromagnetic shielding to safeguard sensitive microcomputer circuit boards.

Minimalist Pure White Flame-Retardant ABS Enclosure

Constructed from high-grade flame-retardant ABS composite material with a refined matte white finish. Impact-resistant and heat-tolerant, its vertical and desktop posture fits naturally into modern home kitchens, vanity counters, and shared suites.

One-Piece Sealed 1.2m Power Cord & Intuitive Rocker Switch Control

Factory-fitted with a sealed, non-detachable 1.2-meter power cable with standard 0.5mm² flame-retardant core wire, eliminating loose connection sparks. An independent rocker power switch and visual status LED enable effortless one-touch power management.

Comprehensive Eight-Fold Smart Protection & Flight-Compliant Portability

Equipped with 8-stage proactive protection covering thermal overload, short-circuit, EMC shielding, leakage sensing, fire resistance, convection cooling, anti-slip stability, and auto-restart. With no liquids or magnets, it travels safely on commercial airlines and rail.

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 800W transformer 220V to 100V/110V, it is essential to follow certain usage precautions and procedures.

Power transformer precautions for use
1, waterproof and moisture-proof
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 energized;
4, the 110V/100V appliances connected to the voltage converter, and then power on the normal use can be.

Q1: How does the SHJY-800VA safely step up 110V to 220V for sensitive appliances?

The SHJY-800VA employs a precision toroidal core wound with high-grade aluminum and wrapped in cold-rolled silicon steel. This design isolates transient spikes, eliminates harmonic distortions, and filters American grid fluctuations, producing a clean, uninterrupted 220V sine-wave output that preserves delicate microcomputer controls in beauty devices and appliances.

Q2: Can I connect both a beauty device and a food processor at the same time?

Yes! The bilateral dual 220V outlets are physically separated on the left and right sides. As long as the combined power of both appliances does not exceed the recommended 640W continuous limit (for instance, a 100W beauty wand and a 300W food chopper = 400W total), both appliances will run concurrently with zero cross-voltage drop.

Q3: What happens if an unexpected electrical short or thermal spike occurs?

The SHJY-800VA is equipped with proactive eight-fold protection. In the event of an external short circuit, the unit trips in milliseconds to isolate the fault. If continuous load pushes the temperature beyond safe thresholds, the smart thermal sensor instantly shuts down power. Once cooled or the fault is removed, power restores automatically.

Q4: Is the SHJY-800VA suitable for travel and international relocation?

Yes. Weighing 3.4kg with compact dimensions of 19×15×6.5cm, it fits smoothly into travel luggage. It contains no magnets, fluids, or hazmat components, fully complying with international air travel and train baggage rules for hassle-free entry into the US and Canada.
