The Verizon USB-C Fast Charge Wall Charger is Verizon's first USB Power Delivery charger with Gallium nitride (GaN) technology, reducing charger size and increasing power efficiency versus other non-GaN 30 watt chargers. Through GaN, the Verizon charger is more compact than most conventional AC chargers as well as able to provide more efficient charging at lower temperatures when supplying power to most mobile phones, tablets, and notebook PC's sold today over the USB Type-C port.
The Verizon USB-C Fast Charge Wall Charger can use USB Power Delivery 3.0 over Type-C to support 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), 30 watts (14.5 volts @ 2 amps) and 30 watts (15 volts @ 2 amps) power profiles for rapid charging as advertised on its product page. Note the charger supports 14.5V Power Delivery Object (PDO) which is not common.
You can use the Verizon USB-C Fast Charge Wall Charger to charge recent Apple iPhone's and iPad's that can use USB Power Delivery like the Apple iPhone 11 Pro Max and 11-inch iPad Pro (2018) or Android phones such as the Google Pixel 4 XL and Samsung Galaxy Note10+ or even smaller notebook computers like Apple's MacBook (Early 2016).
Here's how the Verizon USB-C Fast Charge Wall Charger looks like from inside its box.
The USB-IF logo shows that the Verizon USB-C Fast Charge Wall Charger has been USB certified.
To see how the Verizon 30W USB-C Fast Charge Wall Charger supports power, we used the USB Power Test App from Granite River Labs with the Granite River Labs USB Power Delivery Compliance C2 Tester to produce the following test results.
The USB Power Test App first negotiates a power contract for every PDO supported by the Verizon charger, and increases the load gradually to find the threshold where over current protection (OCP) kicks in and voltage and current start to drop for safety reasons.
The USB Power Test App reports out all the PDO's supported by the Verizon charger and their OCP thresholds. Note OCP thresholds are very low for both PDO #3 and PDO #4.
| PDO | OCP |
|---|---|
| PDO#1 Fixed: 5V 3A | 3.22 |
| PDO#2 Fixed: 9V 3A | 3.21 |
| PDO#3 Fixed: 14.5V 2A | 2.1 |
| PDO#4 Fixed: 15V 2A | 2.09 |
The USB Power Test App from Granite River Labs takes this data to produce an I-V curve which graphically shows the relationship between voltage and current for each PDO. We can observe as the current increases beyond the OCP threshold, the voltage immediately shuts off.
The USB Power Test App can also use the Granite River Labs USB Power Delivery Compliance C2 Tester integrated with the GW Instek APS-7100 programmable AC power supply to compare the charger's power output vs power input so that power efficiency can be measured and compared to regulatory limits from United States of Energy (DOE) Level VI or European Union's CoC Tier 2 requirements. We can repeat the power efficiency tests for different PDO's, current load conditions, and different AC input ranges, allowing us to get a complete picture of power efficiency ranges across all different usage scenarios.
Using the USB Power Test App and FLIR thermal imaging tools, we measured the heat emitted by the Verizon charger as seen in the following temperature graph for the highest 15V, 2A PDO. The max temperature was observed at around 64.1 degree Celsius at 30W.
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 confirm the Verizon charger supports the following fixed PDO's as claimed- 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), 30 watts (14.5 volts @ 2 amps) and 30 watts (15 volts @ 2 amps). Note some compliance failures were also observed.
