【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】
■ Voltage Compatibility
This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).
Many regions use 120V or 220–240V.
Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.
■ Plug Type
This product uses a Japanese plug (Type A or B).
A plug adapter may be required depending on your region.
■ Transformer Requirement (Very Important)
A transformer is required for safe use.
A plug adapter only changes the plug shape and DOES NOT convert voltage.
Using this product without a transformer may cause serious and irreversible damage.
■ Buyer Responsibility
As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.
■ No Return / No Refund Policy
We do NOT accept returns or refunds for:
・Voltage mismatch (including 120V and 220–240V environments)
・Use without a transformer
・Plug incompatibility
・Damage caused by improper setup or usage
■ Liability
We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.
■ Final Notice
Please ensure full understanding of the above before purchasing.
Use only under the correct voltage environment.
Multi-country voltage converter: Supports input voltages of 100V, 110V, 220V, and 230V. Both step-up and step-down conversion are possible; 100V/110V input results in 220V-240V output, or 230V/220V input results in 100V/110V output. Ideal for using foreign-made appliances (kitchen appliances, audio equipment, etc.) in Japan, or Japanese-made appliances (game consoles, beauty appliances, etc.) overseas (a conversion plug may be required).
Choosing the Right Transformer: For safe and stable use, it is recommended that the transformer output be 1.25 to 1.5 times the power consumption of the appliance being used. For example, for a 1500W appliance, the minimum is 1875W (1500W x 1.25), and the safe guideline is 2250W (1500W x 1.5). 2000W is suitable for short-term use, and 3000W is safer for long-term use. Appliances that use the principle of electromagnetic induction, such as electric fans, induction cooktops (IH cooktops), and microwave ovens, generate an inrush current that can reach several times the rated current during startup, potentially overloading the transformer. For such appliances, it is necessary to choose a transformer with a capacity several times the appliance's rated power (for example, a 1000W microwave oven requires a transformer of 3000W or more).
Easy Operation: Select the input voltage (100V/110V/220V/230V) on the back and connect your appliances to the output terminals on the front (100V-110V//220-240V). Simply switch it on and it's ready to use. When using with electrical equipment that may generate surge currents, if the peak value of the surge current exceeds the setting value of the transformer's protection circuit, the protection circuit will activate immediately and shut off the output. You will need to turn the transformer off and then restart it.
Safety features: Equipped with overcurrent, overload, overheating, and short-circuit protection. Automatically shuts down in case of overload or overheating due to prolonged use. Reuse is possible after cooling by resetting the breaker button. Frequent tripping of the breaker may indicate insufficient transformer capacity. Please consider replacing it with a larger capacity transformer to ensure a stable power supply. Please feel free to contact us if you require this. When using for extended periods, please be careful not to block the transformer's ventilation holes. Operating temperature range (0°C to 40°C).
Reliable Support: We also offer consultations regarding product usage and compatible equipment. In the unlikely event of a product malfunction, we will provide prompt replacement or repair. We would appreciate your feedback and suggestions.
1. Before purchasing, please be sure to select the correct power transformer. For example, a regular 45W light is fine with a 100W transformer, but for a 650W microwave oven, we recommend a 1500W transformer. The choice of transformer depends on the efficiency of the electrical product and whether it is a sensory load electrical product. For sensory load electrical products, we generally recommend a transformer with 2-7 times the power. If you have any questions about transformer selection, please contact us by email. 2. Transformers convert voltages from 100V/110V to 220V and 230V/200V to 110V, but they do not support 100V to 110V conversion. When using them, please be sure to understand the correct operating procedure. 3. For 100V to 110V conversion, we recommend a voltage regulator. If the efficiency of the electrical product is not very high, 110V and 100V are almost the same. This product is simply a voltage converter; it is not a ballast or voltage regulator. 4. The transformer fuse blew due to an operating error or incorrect power selection. Calmly press the fuse button to reset it. Wait a while, then try it with a low-efficiency electrical appliance and use it again. It will not damage the transformer.
5. Sometimes the transformer may be damaged during rough handling. If you are concerned, please do not hesitate to contact us. Features of this transformer: 1. Can be used as both a step-up or step-down transformer. The cable connection point is specially designed, so it can be used not only in Japan but also overseas by changing the cable. (200W, 500W, and 5000W are not supported, but if you can change the plug or use a plug adapter, it can be used overseas.) 2. 5V USB port 3. Supports a wider range of countries, compatible with almost all countries with 100V, 110V, 200V, and 230V. 4. While some transformers on the market have a utilization rate of only 50%, our transformer reaches a utilization rate of 80%-90% and can operate 7*24 hours. 5. Once you know the supported power and operating procedure, it is very easy to use, compact and easy to carry. 6. The universal socket is compatible with various electrical plugs, and you can use multiple electrical products simultaneously within the power allowance. 7. Overcurrent protection, overload protection, thermal protection, short circuit protection, quiet operation.
