Voltage Tester for USB 2.0, 4 in 1 OLED Display Digital Multimeter Voltage Ampere Power Capacity Meter - JVR TL59
Does your USB cable or USB adapter work properly? Do you know how much power your USB charging sticks actually hold? JVR TL59 0.91" OLED USB Power Meter can help you easily identify the best cables for USB charging. It shows the voltage, watts, amperage, and the mAh being delivered to your devices. Bright clear display is easy to read and rotation screen for best review. *USB Charging Monitor TL59 shows 4 essentials simultaneously, current, voltage, power and capacity. It is a handy gadget for discovering how much power your USB ports will put out, how much your device will actually draw, how much it takes to fully charge a device, etc. *OLED Screen 0.91inch OLED display is bright enough to see both indoor and outdoor. Current, voltage, and power (current multiplied by voltage) are continuously displayed, and capacity (in mAh) accumulates as long as the input power remains on. *Milliampere Accumulator JVR tester has an accumulator for the number of milliampere-hours of current that have passed through the device. When powered up again, the accumulator flashes the total number of the last test until the new device under test has drawn 1 mAh. *Voltage Reminding When the voltage is less than 4.7 or greater than 5.3 volts, the arrow will be flashing to remind the voltage is too low or too high. Only when the voltage becomes to 4.7-5.3V, the arrow can be disappeared. *Display Flip The readout can be flipped in case you have to plug it in "upside down". The screen rotation button is behind the center perforation. Just press the button, the display will be inverted.
