DROK OLED USB 3.0 Tester with Quick Charge support

Unboxing

The Device is well-packaged in a really nice Aluminum Package, that contains the Tester (of course), a small strap (this one reminds me Baby Toys, i don't know why haha) and an extremely details Manual that i'll show you.

It is made of Plastic, pretty solid (much better than other cheap USB testers) with a nice Blue color.

It supports USB 3.0, so both USB ports have the typical Blue color and the additional pins inside that enables USB 3.0 transmission.

As regards the size, well it doesn't need to be measured. It has the standard size as almost every USB tester. But if you want an example, it is as big as a Standard USB Stick.

The device comes with a bright OLED Screen, with light-blue text on a black background. Its board support multiple interesting features, that i'll gradually show you in this review.

On the back, there is a Key button required to switch between all modes.

Testing

First of all, this is the Official Manual where ALL features are described, with every single How-TO and so on. Even if it isn't written with a perfect English, it is still perfectly understandable.

So, following the Manual's order, the device supports three modes. Direct - Fast - Disconnected.

Using the "Connect" mode, the device will work as a standard tester, without forcing any Quick Charge protocol or something else. (just like you do when you connect a device directly to its charger).

This mode can be used with all devices, without having to worry about compatibility issues. (as you can see, both standard & QC devices work)

Also, as the Manual says, it is clearly noticeable that the Over-Voltage feature works without any issue at all, because on the photo on the right you can see a little arrow just near the voltage.

With the "Fast" mode, you can choose to force AC Charging even using your Computer's USB Ports. You can switch to this mode by pressing the "Key" button while you insert the Tester into your USB port.

As regards the last mode, "Disconnect", i still have to find how it works, so i'll probably update the review as soon as i manage to get it working. If i understood correctly the manual, it works with USB Data devices, and you can "kill" the data transmission to increase charging output, but i am not sure.

In order to make all things easier, there is a LED light that alerts you when it is ready to receive a command (long-press or double-click depending on what you want to do).

You can easily switch between "mAh" & "mWh" by long-pressing the Key button for 2 seconds. (if you keep it pressed for more seconds, the screen will rotate, this is another interesting feature).

The last feature regards its screen mode, you can switch to another more detailed view that will show "mAh" & "mWh" in the same time. (double-click the Key button)

Conclusions

Sincerely i have no words to describe this device...it is awesome! It has almost everything that you need to test your USB devices (almost everything because it doesn't have a Timer and a Temperature Sensor). It is solid, easy-to-use and it doesn't feel cheap as others. It feels Premium. Well Done DROK!

So...do i recommend it? Yes! If you need a professional, reliable USB Tester, this is probably the best choice.

Pros:

- USB 3.0 Support

- Compatible with every single USB device

- Management LED light

- Calibration Mode

- Premium Package

Cons:

- No Timer

- No Temperature Sensor

- A bit expensive (not too much though)
