Convenient and safe: This 110v to 220v converter housing is made of flame retardant material, waterproof and drop resistant. This power transformer has a back hook setting to support wall mounting and easy placement. To use, plug the voltage transformer into the power supply, connect the appliance you need to use to the converter, press the converter switch, and you can use it quickly.

Protection device: voltage power transformer built-in temperature control protection, due to long-term overload use resulting in high temperature, the Power Voltage Converter can automatically cut off the power to protect the appliances, use more secure.

Use Range：500W CE/FCC certified power supply voltage conversion transformer can step up the voltage from 100V-120V to 220V-240V, supporting the use of appliances in the United States in the UK, Europe, China and other regions. However, please allow at least 20% for power surges/spikes.

Maximum use power：This voltage converter production standard is full power output. According to the principle of transformer use, it is recommended that you use the maximum power of 80% of the transformer.for example, 500W transformer maximum use power is 500 * 0.8 = 400W.

About frequency: the rated frequency of this voltage converter is 50/60Hz, if the frequency of the appliance does not match the frequency of the voltage converter, the appliance will also not work.

Note: According to the experimental conclusion of the voltage converter, for hot pot and other appliances that need to be used continuously for more than 90 minutes, please purchase a voltage converter that exceeds two times the power of the appliance.

This continuous use transformer is capable of both up and down voltage conversions for Japan and USA electricity to enable use of Japanese products in USA and USA products in Japan

500 Watts is the maximum capacity of this transformer including the power surge

It converts 110/120 volt USA power to 100 volt Japan power AND 100 volt to 110/120 volts (means it will convert the American power to Japanese power and also convert Japanese power to American)

Power ON/OFF Switch. Fuse protection for safety

Remember to leave at least a 100% margin for power surges/spike when buying a transformer. For power tools, laser printers and heating appliances like Rice cookers, coffee makers, toasters, halogen or fluorescent bulbs you must leave a power spike margin of 4 times. Please Note: Kindly refer the User Manual before use.

★The output voltage can be adjusted arbitrarily: The Adjustable USB Step Up Down Power Supply Module used as a USB input adjustable desktop power supply, the output voltage can be adjusted arbitrarily, and the current limit is 0-2A (wide input 4-13V, wide output 0.5-30V arbitrarily adjusted, with short circuit protection, the short circuit does not burn)

★Used as a USB charging cable, the charging voltage and maximum charging current can be adjusted arbitrarily (any voltage, with constant current, anti-backflow, which can meet the charging of most batteries)

★Three input power modes: Input 1: Standard Type A USB Male. It just can input DC 5V. Input 2: Micro USB Female. It just can input DC 5V. Input 3: IN+ and IN- welding pads. It can input DC 4.0V-13.0V. When using the welding pad to input, be careful not to connect the reversed positive and negative poles, and do not connect to AC power

★Multiple protection functions: short-circuit, over-current, over-temperature, over-power, over-voltage protection, charging anti-backflow protection

★Wide application: It is widely used in ordinary power supply, battery charger, LED driving power, instrument voltage display, test counter, circuit test, power conversion. For more details, please read the user manual
