We put the Huntkey High‑Energy S140 Pro to the test as soon as it arrived. Beyond the specs, real‑world charging experience matters most. For this evaluation, we used the iPhone 17 Pro Max and followed ChargerLAB’s 2050 / 3050 standards to provide a clear, data‑driven look at how this charger in wall performs in everyday use.

Design Overview

The Huntkey High‑Energy S140 Pro continues the series’ signature bold, minimalist design. The type c wall charger features a premium “Titanium Silver” colorway with a finely textured surface that resists fingerprints and scratches. The overall build feels sturdy and well‑crafted, making it a reliable charger 30w and above option for users seeking both style and durability.

In terms of ports, the charger in wall includes two USB‑C and one USB‑A port. Both USB‑C ports support PD3.1, with a maximum output of 140W, while the USB‑A port offers additional flexibility for older devices. The black panel with blue accents gives the type c wall charger a modern, professional appearance.

Full Charging Test

To evaluate real‑world performance, we tested the Huntkey High‑Energy S140 Pro with the iPhone 17 Pro Max in a 25°C environment. The charger in wall quickly negotiated a 15V voltage, and the power draw climbed steadily to 37.8W in the first 9 minutes. It then dropped to 30.7W at 20 minutes, 25W at 26 minutes, and 15.7W at 32 minutes, before continuing at around 9.23W until 57 minutes. After 1 hour and 5 minutes, the voltage shifted to 5V, and the power gradually decreased until the battery was fully charged at approximately 1 hour, 40 minutes, and 46 seconds.

When plotted on a graph, the charging curve shows that the type c wall charger reached 50% in 19 minutes, 69.5% in 30 minutes, 80% in 43 minutes, 90% in 58 minutes, and 100% in about 1 hour and 40 minutes. These results confirm that the charger 30w and above category can deliver impressive speeds even for large‑battery smartphones.

The Huntkey High‑Energy S140 Pro successfully passed ChargerLAB’s iPhone 17 Pro Max 20‑minute 50% charging test, demonstrating its ability to deliver fast and efficient charging in real‑world scenarios.

ChargerLAB’s 2050 / 3050 standards were created to help users easily compare charging speeds.
