[4 Pack] USB C Charger Block Fast Charging Multiport Adapter [PD 20W USB-C & QC 3.0 USB-A Port] – High-Speed Dual Port Wall Charger for iPhone, iPad, Galaxy, Google Pixel & More
The CXX 2-in-1 Fast Charging Wall Charger is a compact, multi-functional power adapter designed to deliver efficient and reliable charging for today’s most popular smartphones and tablets. Featuring both a USB-C Power Delivery (PD) 20W port and a USB-A Quick Charge (QC) 3.0 18W port, it offers versatility, speed, and safety in one portable form factor. This 4-pack ensures that users can keep one charger at home, the office, in their car, or in their travel bag for convenience and consistency.
Dual-Port 2-in-1 Design
The CXX charger combines two high-speed charging ports into a single compact adapter, eliminating the need for carrying multiple chargers. The USB-C port delivers up to 20 watts of power through Power Delivery 3.0, while the USB-A port supports Quick Charge 3.0 technology with up to 18 watts.
This dual functionality allows users to power two devices simultaneously, such as an iPhone and an Android phone, or a smartphone and a tablet. The total combined output when both ports are used at once reaches 15W, ensuring efficient energy distribution while maintaining device safety. Its compact form and lightweight build make it ideal for travel, office use, and daily charging routines.
Fast Charging for Modern Devices
Equipped with PD 3.0 and QC 3.0, this wall charger ensures rapid energy transfer optimized for a wide range of devices. When using the USB-C port, compatible iPhones can charge up to 59% in just 30 minutes, approximately three times faster than a traditional 5W charger.
The USB-A QC 3.0 port provides equally impressive performance for Android devices, reducing charging times significantly. Whether powering a Galaxy S20, Google Pixel, or iPad, the charger automatically detects and delivers the most efficient power level for each connected device. This intelligent charging helps prevent overcharging and maintains battery health over time.
Wide Compatibility Across Devices
The versatility of this adapter is one of its most notable advantages. It works seamlessly with an extensive range of mobile devices and accessories, including:
-
iPhone models: iPhone 17 / 16 / 15 / 14 / 13 / 12 / 11 / X / 8 / SE (2nd Gen) and earlier generations
-
Android devices: Samsung Galaxy S20, S10, Note 10, Note 9, Google Pixel 3, 4, 5 series, LG G7, V30+, and others
-
Tablets: iPad 10.2”, iPad Pro 12.9”, iPad mini 8.3”, iPad Air, and more
-
Accessories: AirPods, wireless earbuds, Bluetooth speakers, and power banks
Because it supports universal voltage input (100–240V, 50–60Hz), it is suitable for international use, making it a practical option for frequent travelers.
Smart Power Distribution and Efficiency
The charger’s internal circuitry is designed to deliver optimal efficiency for every connected device. When charging a single device, the USB-C port provides up to 20W (5V 3A / 9V 2.22A / 12V 1.67A), while the USB-A port offers up to 18W (5V 3A / 9V 2A / 12V 1.5A).
When both ports are in use, the smart power management system distributes a combined output of 15W, maintaining stable performance for both devices. This intelligent energy balancing ensures neither device is underpowered or overheated during dual charging.
Superior Safety and Reliability
Safety is a top priority for the CXX charger. It conforms to ETL safety standards, which verify that the product meets North American electrical safety and performance requirements.
The built-in multi-protection system includes:
-
Temperature control, preventing overheating during long charging sessions
-
Overcurrent and overvoltage protection, which safeguard both the charger and connected devices
-
Short-circuit prevention, ensuring a reliable power supply under all conditions
-
Automatic power adjustment, which fine-tunes output based on the needs of each device
These features work together to protect both your devices and your peace of mind, making the charger a dependable choice for everyday use.
Compact and Travel-Friendly Build
The CXX Fast Charger Block is designed for portability. Measuring 2.19 × 1.58 × 2.44 inches, it fits easily in small bags, laptop cases, or even pockets. The compact cube shape minimizes bulk, while the sturdy casing resists wear and impact during travel.
Despite its size, the charger maintains powerful performance and stable output. The foldable prongs make it more space-efficient, reducing the risk of damage during transport. This thoughtful design enhances both usability and longevity.
Efficient Heat Dissipation
Unlike bulkier adapters that heat up quickly during fast charging, this model employs efficient heat management materials to maintain safe operating temperatures. The internal thermal sensors continuously monitor heat levels and adjust current flow as necessary. This ensures consistent power delivery and prevents thermal stress that can shorten device battery life.
User-Friendly Design and Compatibility Tips
The dual-port layout allows users to access both connections simultaneously without obstruction. The ports are clearly labeled, helping identify the PD (USB-C) and QC (USB-A) sides.
For iPhones (8 and later) and iPads (pre-2018 models), a USB-C to Lightning cable is required to enable full Power Delivery speed (sold separately). When both ports are used at once, the charger automatically balances power output to ensure safe and stable charging.
Although it’s not intended for high-wattage devices like laptops, the adapter efficiently handles smartphones, tablets, earbuds, and smaller electronics that operate within the 15–20W power range.
Practical for Everyday and Multi-Device Users
Owning a 4-pack of these dual-port adapters adds convenience for households or workplaces with multiple devices. Each family member or office desk can have a dedicated charger, reducing clutter and the need to constantly swap adapters.
Having multiple chargers also ensures readiness in multiple environments — one in the car, one at home, one at the office, and one for travel. This flexibility helps maintain continuous power availability wherever you are.
Durability and Long-Term Performance
The charger’s casing is made from flame-retardant, high-strength plastic that resists cracking and discoloration. The internal components are built with high-quality capacitors and solid-state protection chips, improving longevity and power stability.
Unlike low-quality alternatives, this model maintains its performance even after repeated plugging and unplugging. The strong construction ensures a reliable charging experience day after day, supporting your devices’ power needs for the long term.
Energy Efficiency and Environmental Considerations
The CXX adapter is designed to minimize energy loss and meet international efficiency standards. It automatically reduces power output once the connected device reaches full charge, conserving electricity and preventing unnecessary battery wear.
This energy-smart approach makes it an environmentally conscious choice, balancing high-speed performance with responsible energy use.
