Introduction
With the full launch of the iPhone 15 series, many users have likely already purchased their new devices. While the battery capacities of the new iPhone models have seen various improvements, there is no noticeable difference in overall battery life. For car owners, a car charger is an essential accessory, providing emergency power to smartphones, tablets, and even laptops. Today, we will take a closer look at the performance of the Comtar 30W Car Charger, which is capable of quickly charging both iPhone and Android devices.
Unboxing
The Comtar 30W car charger comes in a transparent shell with paper packaging, allowing you to see the charger itself. The top left corner features the "Comtar" brand name, along with a diagram indicating the output ports. The bottom highlights the charger’s key features: 30W output, PPS fast charging, and a charging indicator light, making it compatible with smartphones, tablets, and other devices.
On the back of the packaging, you’ll find relevant specifications and recommended compatible devices:
- DC Input: 12V~24V
- Output Options: 5V/3A, 9V/3A, 12V/2.5A, 15V/2A
The design of the 30W car charger is a standard cylindrical shape, with a matte black finish that feels smooth to the touch.
The output panel features a single Type-C output port, with a power indicator light above it. Below the port, you’ll find the “30W PD” power rating and the “Comtar” brand name.
When powered on, the charging indicator light glows orange-red.
The charger has circular metal contact points on both sides, ensuring compatibility with standard cigarette lighter sockets. It measures approximately 66.67mm in length and 27.27mm in diameter, weighing around 16.2g—comparable to the weight of three one-yuan coins.
Protocol Testing
The protocol testing module assesses the charger’s compatibility with fast charging protocols. Users can match their devices based on specific protocols. Since car battery voltages vary between 12V and 24V, we tested the charger under both conditions to ensure an optimal fast charging experience.
Summary
The Comtar 30W car charger features a conventional cylindrical design with a sleek matte black finish. Its compatibility is consistent across both vehicle voltage types, showing no significant differences in performance.
In terms of performance, the USB-C port supports a maximum output of 30W. During compatibility testing, we noted that despite the different voltage levels, the charger effectively negotiated the appropriate voltage for various devices. The USB-C port achieved a charging power of up to 28.93W.
Ripple and temperature tests demonstrated the charger's output quality. Under both voltage conditions, the ripple values remained below 12mVp-p, with superior output quality observed at 12V. In a controlled environment at 25°C, the charger was tested at a maximum load of 20V1.5A (30W) for one hour, with the highest temperature reaching 36.4°C—only slightly above average body temperature.
Overall, the Comtar 30W car charger performs consistently across different vehicle voltage levels, meeting user demands for fast charging while maintaining low heat generation, ensuring safer driving conditions. If you’re looking for a reliable car charger that can efficiently power your devices on the go, the Comtar 30W is a solid choice.
