【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.
[100V/110V ⇋ 220V/240V Voltage Transformer, Output Voltage LED Display] Input Voltage: 100V/220V Output Voltage: 100V/220V 50/60Hz This voltage transformer allows you to use Japanese electrical appliances while traveling abroad. It also makes it easy to use overseas electrical equipment in Japan. The output voltage is displayed in real time. After powering it on, the transformer automatically identifies the input voltage and converts it to a step-up/step-down voltage. Simply plug it in and it's ready to use!
[LED Fault Code Indicator, Safety Protection Included] OUTPUT: 2 outlets (suitable for 100V-120V electrical appliances), 2 outlets (suitable for 220V-240V electrical appliances), Safety temperature control protection (thermostat), Input/Output overvoltage protection, Input undervoltage protection, Overcurrent protection, Overheating protection, Overload protection. Err HI: Input/Output overvoltage protection. Err LO: Input undervoltage protection. Err OH: Overheating protection. Err OL: Short circuit or overcurrent protection. PonIIIII: Input voltage is recognized.
[Caution Regarding Voltage Conversion Efficiency] Please use at approximately 80% of the rated capacity. For safe and stable use, it is recommended that the transformer output be 1.5 to 2 times the power consumption of the appliance being used. Example: For a 1000W appliance, the minimum is 1500W (1000W x 1.5), and the safe guideline is 2000W (1000W x 2). 1500W is safe for short-term use, and 2000W is safe for long-term use.
[Supports 90V-260V input voltage] In Japan, the voltage range is set to 100V ⇋ 220V, allowing input and output voltages from 90V to 260V. Calculation formula: Actual output voltage / Actual input voltage = Constant output voltage / Constant input voltage (100V/220V = 100V/220V) Example: If the input voltage is 100V, the output voltages will be 100V and 220V. If the input voltage is 110V, the output voltages will be 110V and 240V.
[Precautions for using transformers] When using high-power electrical appliances or inductive loads such as motors or compressors, please select a transformer with sufficient capacity. As a guideline, use a transformer with a capacity of 2 to 4 times the rated output of the electrical appliance. Note: The product model number is affixed to the bottom of the product.
