I put a PortaPow in series with a this DROK unit and used an electronic load MAYNUO M9712C USB Programmable DC Electronic Load 300W 0-60A 0-150V via a USB breakout box Breakout Board for USB Mini-B. It drew power from a Nexus 7 charger. I dialed up current. The Nexus 7 supply has current limiting protection and shuts off at 2.5A. At all times, the DROK, PortaPow and electronic load read identically from 0.01A to 2.5A, as well as output voltage. The voltage output began to drop quickly after 1.9A, but this was an issue for the charger or the cabling than for the volt-ammeter. I let the units run for > 24 hours charging a Nexus 7 and all devices read the output voltage and current identically.

Pros
accurate volt and ammeter
dual-LED easy to see indoors
compact
dual USB jacks
Power draw of the device is less that 10mA, and does not significantly load the test devices or PSU

Cons
No brand name, you can find many identically looking devices under many brands and vendors, you can't be sure if it was made by the same person, its fake or counterfeit, or works properly without testing it yourself
LED are difficult to see in outdoors and worse in sunlight

I troubleshoot USB with a USB breakout box that is tedious to set up and having this device makes it plug and play for quick status checks for charging or USB devices.

This is a very handy tool that I purchased to use in measuring the current and voltage of USB circuits and to evaluate whether or not the capability of USB devices is as advertised (for example, does a USB charger deliver 2.1 or 2.4 Amps, or less?).

There are two outputs available:
- 'Output I' - can be used for both charging and data transfer, and will support high current charging rates of 2.1-2.4 Amps as used by many tablets and larger devices
- 'Output II' - use for charging only, will not support data transfer, and will only provide a maximum of 1.0 Amps

Both USB outputs can be used simultaneously. This allows chargers for example to be loaded with two devices to max out and measure their capability.

A couple of important points to make:
- there are (at least) two brands of this meter being sold on Amazon - BESTOPE, and DROK
- the DROK product is ALMOST identical in appearance to the BESTOPE Digital LED USB Amperemeter Voltmeter, also listed on Amazon here BESTOPE Dual-USB Output Charging Detector Digital LED Ammeter Voltmeter. These BESTOPE meters, however, are what I now consider a 'basic' version of this particular meter design, and do not include the seven display modes (see second DROK listing below)
- there are two listings on Amazon for the DROK meter:

I supported PortPilot on Kickstarter ... and I like it.
But, I wanted to try the much less expensive Drok device.

[Amazon is conflating the *TWO* different Drok USB analyzer products ... my review of the Drok Dual USB device is showing up for both it and for the Drok Mini device ... so, I've edited the review to discuss each device.]

1. Drok Dual USB ...

The DROK dual-usb hub/charger/etc. is significantly less expensive than the PortPilot and does a great job of showing me the current being pulled by my USB devices.

Recommended!
DROK® Dual-usb 2.0 HUB with 2 Ports for Fast Charging & Data Sync Charger Doctor Voltage Current Detector Digital Ammeter Voltmeter Multimeter Solar Panel Alignment Tester Mobile Power Panel Monitor Gauge Dc 3.2-10v 0-3a Red Blue LED

2. Drok Mini-USB (blue display, rotation button)

This device is NOT as good as the other Drok (and, it costs 50% more!)

The screen rotation button is hidden inside what looks like air vent holes (there are 9 holes ... the one in the middle is where a "button" exist ... use a paperclip to press it).

When plugged into the USB 2 port of a modern laptop, with a Galaxy S5 plugged in to charge, Windows indicated it was getting repeated "I'm here" signals, once every second or so. The problem disappeared when we used a USB port on a hub. But, this indicates a design problem and/or a bug in our test unit. Either way, it's not a good sign.

The unit I received is NOT a DROK as shown in the photos. It has no brand name on it. The description clearly states a switch for 7 different display modes. I received a unit with no button for these 7 display modes. Its irritating to NOT receive the model as stated in the description. Its hard telling which one you might receive.
