【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.
[500W Step-Up/Step-Down Transformer] This transformer can convert 220V overseas outlets to 100V, converting them to Japanese voltage. It can also convert 100V to 220V, converting them to voltages used in various countries overseas. As an overseas voltage converter, you can use Japanese electrical appliances when traveling abroad. You can also easily use overseas electrical equipment in Japan.
【LCD Output Voltage Display】 500VA Transformer: No more worries about malfunctions caused by not adjusting the input voltage (100V or 220V). The transformer automatically detects the input voltage after being powered on. The LCD screen displays the output voltage in real time. When the input voltage is 100V, 100V and 220V appliances can be used simultaneously. When the input voltage is 220V, 220V and 100V appliances can be used simultaneously.
[Safety Features, LCD Fault Code Display] 500W Overseas Voltage Converter OUTPUT: 1 outlet (suitable for 100V-120V electrical appliances), 1 outlet (suitable for 220V-240V electrical appliances), 10A circuit breaker protection, input/output overvoltage protection, input undervoltage protection, overcurrent protection, overheating protection, overload protection. LCD Fault Code Display: Err HI: Input/Output High Voltage Protection Err LO: Input Undervoltage Protection Err OH: Overheating Protection Err OL: Overcurrent Protection PonIIIII: Input Voltage Recognized
【Voltage Conversion Efficiency】The 500VA transformer has a conversion efficiency of 85%. The toroidal transformer enhances voltage conversion efficiency and extends its service life. The input voltage is 100V, and the no-load voltage is 220V±5V. The output voltage drops by approximately 10% (between 198V and 220V) depending on the load. The output voltage changes in real time according to the input voltage and is not constant.
[Transformer Usage Precautions 1] The AC output outlet of the transformer is internally grounded, and the power cord is a standard Japanese plug without grounding. Since the power cord is a 2-prong plug, you will need to purchase a separate high-power adapter plug when using it overseas.
[Transformer Usage Precautions 2] 100V cannot be converted to 120V. 200V cannot be converted to 220V.
[Transformer Usage Precautions 3] When using high-power electrical appliances or inductive loads such as motors/compressors, please choose a transformer with sufficient capacity. Some electrical appliances, such as hair dryers, hair irons, heating appliances, power tools, coffee makers, and laser printers, require 2 to 4 times their rated power when starting up.
[Transformer Usage Precautions 4] The initial setting of this product is AC100V to AC220V. Since the transformer is not a voltage regulator, it cannot always maintain a constant output voltage value. The output voltage will drop to various degrees depending on the power consumption of the input appliance, but it will still be able to start up normally.
