Pros
Compatibility with USB-PD.
Thorough safety measures.
Adapters included with compatible smartphones.
Cons
Potentially slower than some standards.
SuperCharge, Chinese smartphone maker Huawei’s proprietary charging standard, is built into phones like the Huawei P30 Pro, Huawei Mate 20 Pro, and the Huawei P10. It’s somewhat akin to Quick Charge in that it uses higher-than-average voltages to achieve faster charging, but there’s slightly more to it than meets the eye.
Tech specs and compatible adapters
SuperCharge automatically adapts the incoming wall voltage and current based on the condition of the phone’s battery and the phone’s internal temperature. Older SuperCharge-compatible wall adapters and car chargers support three charging modes — 5V/2A, 4.5V/5A, and 5V/4.5A (up to 22.5W) — and use an in-charger chipset to regulate voltage, eliminating the need for heat-producing in-phone voltage transformation. The latest version offers 10V/4A for up to 40W.
Unlike proprietary charging standards like Pump Express and Dash Charge, Supercharge is compatible with USB-PD. That’s thanks to Huawei’s Smart Charge protocol, which intelligently switches between charging modes depending on which charging adapter is plugged in.
Tapping into Huawei’s SuperCharge technology requires buying a compatible wall adapter, but native compatibility with Qualcomm’s Quick Charge standard means any SuperCharge-compatible devices can take advantage of Quick Charge. Every SuperCharge-compatible smartphone comes with a compatible wall adapter.
Charging speed
Huawei doesn’t provide charging estimates for SuperCharge, but we were able to fully charge the Mate 20 Pro in around 1 hour and 10 minutes.
Safety measures
Huawei’s Smart Charge protocol, a proprietary part of the SuperCharge spec, identifies the load capacity of the charger and cable and reduces the voltage to match.
In addition, SuperCharge uses specialized components that are “optimized” to handle higher currents, including an eight-layer cooling system and special lining that keeps devices up to 5-degrees Celsius cooler than other fast-charging standards. Huawei says that SuperCharge devices undergo a year’s worth of testing and 10 reliability tests covering everything from short-circuits to extreme temperatures.
