Main highlights

•【MULTI-FOUNCTIONAL USB C POWER METER】Professional UT658Dual LCD USB tester detector is designed accurate, reliable, stable and easy to carry. Can measure output voltage, current, energy, capacity, circuit equivalent resistance, D+ and D- voltage of USB data cable, and more.
•【WIDELY APLICATED】The 2nd generation UT658Dual USB testers can inspect USB chargers, portable power sources, data cables and other electronics charging devices with Type-C, USB/Type-A interfaces. Support fast charge protocol 2.0/3.0/4.0
•【PROTECT YOUR DEVICE】 Our digital voltmeter ammeter can monitor the charging efficiency well, check the current and voltage of the device conveniently, and protect the charging device.
•【HIGH VISIBILITY】The LCD function of the voltage/amps power meter can display all the measured numbers at any time, and the same screen can display voltage, current, power, capacity, etc. It has 10 groups of data storage capacity.
•【GREAT ENGINEERING TESTING TOOLS】This LCD USB tester detector is a great tool for applications such as production verification, engineering testing, and DIYers.
•★★ NOTE ★★★ - Type-C and Type-A are two modules. The correct way to use them is that Type-A port input corresponds to Type-A port output, and Type-C port input corresponds to Type-C port output. UT658Dual does not support Type-C input, docking Type-A output, otherwise the A port will not respond.
