About this item

  • NEW Arrival USB Tester: Upgraded color USB tester feature a 12,800 pixel IPS HD colour digital LCD screen for clear readings; screen rotation function allows readings to be taking in different directions. Meanwhile, to ensure more accurate measurements, USB meter tester uses a sampling chip with an internal resistance as low as 1 milliiohm (1mΩ), reducing self-consumption while providing you with more reliable values. d car charges more easily.
  • Multi-functional USB meter. USB meter tester is mainly used to detect USB charging current, voltage, capacity, power, time, etc, displaying accurate data for you in real time; detecting the quality of charger and cables, providing a safe charging environment for your valuable devices. USB tester can automatically detect different fast charging protocols, including APPLE 2.4A/2.1A/1A/0.5A; Android DCP/AFC; HUAWEI FCP 9V/2A, SCP 4.5V/5A; Samsung Qualcomm QC2.0/3.0.
  • Power-off Memory Function: Testing the capacity of a power bank requires completing discharge process from 100% to 0, which will take a considerable amount of time to complete it. Power failure storage feature allows you to finish this process in one or more passes, as it will accumulate capacity again when power on again. Up to 9 sets of data help you easily calculate the real capacity. Screen can be shut off during this process or at night for distraction-free experience.
  • Wide Test Range & Simple Operation: Input/Output Voltage: DC3.6-30V, Current Range: 0-5.1A. Large range of USB meter makes it widely compatible with USB-A port devices such as mobile phones, tablets, laptops, car chargers, power banks, wall chargers, cables, etc., displaying charging data to you in real time. USB tester is compact and portable, providing a safe environment for charging every time, wherever you go.

Very useful testing tool, five stars if it had a manual.
4 Stars
Very useful testing tool, five stars if it had a manual.
The Good:Very useful for testing real-time Voltage, current, capacity, charging temperature while a device is charging. Also to check if a battery pack can deliver its advertised capacity.If unplugged it keeps memory from last usage. While on, it can be deleted by pressing the button twice.It supports devices with QC2.0, QC3.0, BC1.2 (Battery Charging revision 1.2) & Apple voltage range.You could switch to three different display screens by just pressing the only button on this USB Digital Power Meter Tester.It appears to be very accurate.The Bad:No manual. I spent some time tinkering with it to find out all the info available here.I wouldn't know if there are other hidden settings.More Info:It is quite amazing what you can accomplish on this device with just one button.-Pressing the button once takes you to the next screen-Pressing the button once and holding until it beeps resets all-Pressing the button twice resets the capacity (Cap:)-Pressing the button three times resets energy (Ene:)-Pressing the button four times resets time (Time:)-Pressing the button five times, toggle the setting next to time: Off/AO/Manual-Pressing the button six times changes language from Chinese to English.The setting next to time on the second screen has three modes:-Off [device will be running non stop]-Automatic Off (AO..) [device will power off after it detects power draw stops].-Manual [device will power off after specified time].Automatic Off (AO..) and Manualare very useful if you don't want a device to keep drawing a little bit of current here and there after fully charged. Especially if you want to extend the live of your device Lithium-ion or to stop draining a battery pack.To set it to 'AO..' (from 'OFF') press button five times 'AO..' will blink then wait for device to beep.To set it manually to a specific time (from 1-24 hours), press button five times 'AO..' will blink, press one more time '24' blinks. Pressing button once will decrease the time by 1 hour (24, 23, 22, 21, etc) but if you press twice it will increase (21, 22, 23, etc). Since there is only one button you will have to go back to '24' to be able to select 'AO..' or 'OFF' again.Below, the data that could be displayed on each of the 3 screens.The 1st screen has 6 entries.Left (from top)-Voltage-Amps-Running timeRight (from top)-Watts-Amp Hours-Watt HoursThe 2nd screen has 8 entriesLeft (from top)-Negative pin (V-)-Positive data pin (D+)-Negative data pin (D-)-Positive pin(V+)Right (from top)-Resistance (O)-Temperature (°C)-Time-AmpsThe 3rd screen has 4 entriesFrom top-Voltage (V) / Current (A)-Capacity (Cap)-Energy (Ene)-Time (00:00:00) / Automatic Off (AO..)
