The ACEFAST B21 75W Fast Charge Car Charger is designed to provide powerful and efficient charging while driving. A combined output of up to 75W is delivered through two charging ports, including a 45W USB-C port and a 30W USB-A port, allowing two compatible devices to be powered simultaneously. Support is provided for multiple fast-charging protocols, including PPS, PD3.0, PD2.0, QC4+, QC3.0, QC2.0, AFC, FCP, and SCP, depending on the selected port.
A durable zinc alloy and PC construction is used to provide improved heat dissipation and everyday durability. An ice-blue LED ambient light is integrated for improved visibility inside the vehicle, while intelligent power distribution is used to adjust voltage, current, and power according to the connected device. Compatibility with DC 12–24V vehicle systems allows the charger to be used across a wide range of cars, SUVs, and trucks.
Key Features
75W Dual-Port Fast Charging
A total output of up to 75W is provided when the USB-C and USB-A ports are used together. Up to 45W is delivered through USB-C, while up to 30W is supplied through USB-A, allowing two devices to be charged simultaneously.
45W USB-C with Buck-Boost Technology
Stable charging performance is supported through the USB-C port's buck-boost technology. Power delivery is regulated to accommodate voltage variations within compatible vehicle electrical systems.
Multiple Fast-Charging Protocols
Broad device compatibility is provided through support for popular charging standards. Depending on the port being used, PPS, USB Power Delivery, Qualcomm Quick Charge, AFC, FCP, and SCP protocols are supported.
Intelligent Power Distribution
Charging voltage, current, and power are dynamically managed according to the requirements of connected devices. Efficient charging is maintained while unnecessary heat generation is reduced.
Dual USB-C and USB-A Connectivity
A USB-C port and USB-A port are provided, allowing modern USB-C devices and traditional USB-A charging cables to be used from a single car charger.
Multi-Level Safety Protection
Protection against over-current, over-voltage, over-temperature, short circuits, and excessive power is built into the charger. Connected devices and the charger itself are protected against common electrical charging risks.
Zinc Alloy Construction
A combination of zinc alloy and PC is used for a durable and compact body. Improved heat dissipation is supported by the metal construction during high-power charging.
Ice-Blue LED Ambient Light
An integrated ice-blue LED light is provided around the charger, making the ports easier to locate in low-light vehicle interiors while adding a clean, modern appearance.
12–24V Vehicle Compatibility
Compatibility with DC 12–24V input systems is provided, allowing the charger to be used with a wide variety of compatible vehicles, including cars, SUVs, and trucks.
International Certifications
The charger has been certified according to RoHS, CE, EAC, and FCC standards.
