The Nekteck NK-TC-PD30 51W Dual Port USB Type-C PD Wall Charger is one of the many chargers sold by Nekteck which also includes the Nekteck 46W USB-C Wall ChargerNekteck 65W USB-C Power Delivery Wall Charger and Nekteck 72W USB Type-C PD Charger Station. The Nekteck NK-TC-PD30 51W Dual Port USB Type-C PD Wall Charger comes with each a 39 watts based USB Type-C and a 12 watts based USB Type-A charging output, which is also similar to the Monoprice PD52U-2UT01 39W Dual USB Wall Charger and the Choetech PD51-1C1U 51W Dual Port USB Type-C PD Wall Charger.

By supporting 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps) and 39 watts (15 volts @ 2.6 amps) over USB Type-C, the Nekteck NK-TC-PD30 51W Dual Port USB Type-C PD Wall Charger allows you to charge most notebook PC's in the market as well as tablets and phones. Even though the charger shows that it has been certified by the USB-IF through the USB certification logo, it fails many USB compliance tests (see more details at the bottom of this review) so be extra careful when using this charger. Note that the same problem was also seen with the Monoprice PD52U-2UT01 39W Dual USB Wall Charger (in this review) and the Choetech PD51-1C1U 51W Dual Port USB Type-C PD Wall Charger (see this review).

Note that while the Nekteck NK-TC-PD30 51W Dual Port USB Type-C PD Wall Charger supports USB Power Delivery based charging, it can also support Qualcomm Quick Charge technology to charge Qualcomm Quick Charge enabled phones (click here to see how we tested this charger with the Xiaomi Mi 5 phone).

The packaging also includes a separate USB Type-C to Type-C cable accessory which doesn't require using your own cable with the charger.

The charger has two standard foldable prongs to plug into a AC wall outlet for charging.

If compared side by side, the Nekteck NK-TC-PD30 51W Dual Port USB Type-C PD Wall Charger has a design that is very similar to the Monoprice PD52U-2UT01 39W Dual USB Wall Charger and the Choetech PD51-1C1U 51W Dual Port USB Type-C PD Wall Charger. Like both these two other chargers, the Nekteck USB Type-C port also supports Qualcomm Quick Charge technology besides USB Power Delivery for charging (click here to see more).

You can connect your phone or tablet to the USB Type-A port for 12 watts (5 volts @ 2.4 amps) of legacy charging.

Using the USB Power Delivery Compliance C2 Tester from Granite River Labs to run just a subset of the full USB Power Delivery compliance test suite, we can see that while the Nekteck NK-TC-PD30 51W Dual Port USB Type-C PD Wall Charger supports 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps) and 39 watts (15 volts @ 2.6 amps) PDO's, it also supports an additional 36 watts (12 volts @ 3 amps) PDO which is not listed in the charger's specs. Also given that compliance failures were mostly observed even though the charger shows it is USB-IF certified, it is better to take precautions when using this charger.
