Mophie Speedport 40 - 40W GaN FAST Wall Charger

The Mophie Speedport 40 is a premium, dual-port wall charger that represents the convergence of high-speed charging, intelligent power management, and exceptional portability. It leverages next-generation GaN semiconductor technology to deliver robust 40W of total power in a form factor smaller than many single-port laptop chargers. It is engineered for the user who demands fast, reliable, and compact charging for a modern ecosystem of USB-C devices.

1. Core Technology: GaN (Gallium Nitride)

• The Foundation: This charger replaces traditional silicon transistors with GaN (Gallium Nitride), a more efficient semiconductor material.

• The Result: This allows for a dramatic reduction in size and heat generation while improving efficiency. The "40" in its name refers to the total 40 Watts of power output, which GaN technology delivers in a package approximately the size of a standard 1.5-inch cube (specific dimensions: ~1.8” x 1.8” x 1.1”).

2. Port Configuration & Intelligent Power Delivery

This is the charger's defining feature. It features two (2) USB-C ports equipped with smart, dynamic power allocation.

• Single-Port Mode (Max Output): When only one port is used, it can deliver the full 40W of power. This is ideal for power-hungry devices like:

  • MacBook Air / iPad Pro (fast charging at peak rates)

  • Large Tablets

  • Any single smartphone at its maximum supported speed.

• Dual-Port Mode (Intelligent Splitting): When both USB-C ports are in use, the charger dynamically allocates the 40W total. A common split is 25W to the first port and 15W to the second, but this can adjust based on device needs. This allows for powerful, simultaneous charging of combinations like:

  • A Samsung Galaxy phone (using 25W) + an iPhone (using 15W).

  • An iPhone + an iPad Air.

  • Two smartphones simultaneously at speeds faster than standard charging.

3. Advanced Charging Protocols & Compatibility

The Speedport 40 is not just a high-wattage charger; it's a smart one, supporting key fast-charging standards to ensure optimal speed across a wide range of devices.

• USB Power Delivery 3.0 (PD 3.0): The universal standard for fast charging. Essential for modern iPhones (iPhone 8 and later, optimized for iPhone 12-15 series), iPads, MacBooks, Google Pixel devices, and many Windows laptops.

• Programmable Power Supply (PPS): A critical subset of PD 3.0. PPS allows for fine-grained voltage adjustments, which minimizes heat and maximizes efficiency. It is specifically crucial for achieving the full 25W Super Fast Charging on Samsung Galaxy S-series phones (S22 and later).

• Broad Voltage Coverage: It supports common fast-charging voltages like 5V/3A, 9V/3A, 12V/3A, 15V/2.66A, and 20V/2A, making it versatile for everything from earbuds to laptops.

4. Design & Build Quality

• Form Factor: Dense, compact cube design with a matte, scratch-resistant polycarbonate finish.

• Foldable Prongs (US Model): The integrated US plug prongs fold flush into the charger's body. This is a critical feature for travel, protecting both the charger and other items in your bag from scratches.

• Indicators & Safety: A small, white LED power indicator is discreetly placed. The charger is built with multiple layers of protection, including Over-Current Protection (OCP), Over-Voltage Protection (OVP), Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP).

5. What's Included & What's Not

• Included: The Mophie Speedport 40 40W GaN Wall Charger unit only.

• Not Included: No USB-C cables are provided. You must use your own high-quality USB-C to USB-C or USB-C to Lightning cables rated for the power levels you require.

Ideal User Profile: Who Is This For?

1. The Apple Ecosystem User: Perfect for someone with an iPhone and a MacBook Air or iPad Pro. It can fast-charge the iPhone (up to ~25W) and provide full power to the laptop (30W+) from a single, tiny brick.

2. The Samsung Galaxy Power User: One of the best compact chargers for Galaxy devices due to its PPS support, enabling full 25W Super Fast Charging.

3. The Minimalist Traveler: Eliminates the need for multiple chargers. One compact brick charges a laptop, phone, and tablet. The foldable prongs are a key travel benefit.

4. The Workspace Declutterer: Its small size and dual-port capability make it an excellent permanent fixture on a desk, nightstand, or kitchen counter, reducing cable clutter.
