【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Voltage and Current Checker: This device can easily check the voltage, current, capacity, power, temperature, load impedance, D++/D voltage, and charging time of Type-C and USB devices. The plug and the product to be tested must be connected during use; otherwise, the test may be inaccurate.
Professional-grade measurement accuracy: Even compared to larger professional voltage and current testers, our tester maintains exceptional test accuracy.
USB 3.0 Voltage and Current Checker: Monitors QC2.0/QC3.0/MTK-PE/iPhone/Android and other charging protocol data. USB 3.0 provides more stable transmission and more accurate readings.
Extensive numerical display: Instantaneous current (A), cumulative current (mAh), voltage (V), instantaneous power (W), cumulative power (Wh), temperature (℃), current flow time (h:m:s), and electrical resistance (Ω). Eight pieces of information can be displayed at a glance on the voltmeter.
Power measurement range: 0-9.99W, Voltage measurement range: 3.6V-32.0V, Current measurement range: 0-5.10A
Charging Safety Protection: The USB voltage and current checker has overvoltage, undervoltage, and overcurrent protection functions. Check your phone's charging status anytime after connecting your phone, and monitor charging data in real time while charging, protecting your smart device.
OTG Upgrade: With Type-C OTG protocol, you can turn on OTG digital function by inserting the Android switch header randomly embedded in the upper left corner of the Android circuit. The upgraded OTG not only looks more advanced, but also more convenient to use.
