【7 Modes Display Monitor】 DROK USB Tester is equipped with digital color LED display screen, which can be switched between 7 display modes. This multimeter can be used to measure voltage, current, power, capacity. Through the 7 modes, you can clearly see the voltage, current, capacity and power during charging. Only 1 button to switch the display mode, simple and handy. 【Dual USB Output】 This item is equipped with USB-A USB-C input and dual USB 2.0 output. The output ports support PD QC 3.0 fast charge protocol. This meter can auto identify the fast charge protocol, which can charge your device among 3.6V to 12V 3A. Output Ⅰ can be used for device charging and data transfer, and output Ⅱ can only be used for charging. 【Multifunction】 DROK USB detector can be used for capacity checking, capacity clear, over voltage, under voltage, over current and short circuit alarm, which is easy to test the power, quality and know the health condition of your device chargers or USB cables. 【Easy to Use】 The multimeter only has Two button. Once you plug in the meter, you can test the parameter you want. The button Ⅱ can switch 7 modes display——VA(Voltage & Current), C(Capacity), P(Power), VA+C, VA+P, C+P, VA+C+P. 1. Please note that The latter 4 models is cyclic display. If you dislike the cyclic display modes, Just press the button Ⅱ to former 3 modes which are all fixed display. When voltage ≥ 5V, power on and long press button Ⅰ for 5 seconds to activate output. 【Application】 DROK USB Meter can be used for the devices between 3.2-30V and 0-5A. You can use this for 5V 9V 12V 24V 30V solar panel, power bank, battery charger, USB able.【Note】If you use USB-C IN and USB-A OUT, long press button I to Start Output. Is your device not charging properly, and you suspect the new charger that you bought recently?
