OntheGo 67W Slim Wall Charger Review: Compact GaN Power for Travel and Desk

Traveling with multiple devices often means carrying a tangle of chargers and adapters. The Satechi OntheGo 67W Slim Wall Charger aims to solve this with a compact, high-power design that fits in the palm of your hand. In this review, we put this GaN charger to the test—evaluating its build quality, charging speed, portability, and real-world performance for laptops, tablets, and smartphones.

Whether you're a digital nomad, a frequent business traveler, or simply looking to declutter your desk, a reliable multi-port charger is essential. The OntheGo 67W charger promises to deliver fast charging for a MacBook Air or Pro, an iPad Pro, and an iPhone simultaneously. Let's see if it lives up to the hype and how it compares to other compact chargers on the market.

Design and Build Quality

The first thing you notice about the OntheGo 67W Slim Wall Charger is its size. Measuring just a bit larger than a standard credit card, it uses GaN (Gallium Nitride) technology to pack 67 watts of power into a remarkably slim profile. The charger features a sleek matte black finish with a subtle Satechi logo, and the foldable prongs make it easy to slip into a laptop bag or pocket without snagging.

Build quality is excellent—the casing feels solid and resistant to scratches. The dual USB-C ports are spaced far enough apart to accommodate thicker cables, and the charger supports a wide range of voltages (100-240V), making it suitable for international travel with a simple plug adapter. Overall, the design is minimalist and functional, perfect for users who value portability without sacrificing power.

• Dimensions: 2.9 x 1.9 x 1.1 inches (74 x 48 x 28 mm) – truly pocket-friendly.
• Weight: only 4.2 ounces (120 grams) – lighter than many single-port 30W chargers.

Charging Performance and Speed

When it comes to charging, the OntheGo 67W charger delivers on its promises. Using a single USB-C port, it can output the full 67W, enough to fast-charge a 13-inch MacBook Pro from 0 to 50% in about 30 minutes. When both ports are in use, the power is split dynamically: 45W + 20W, which still provides fast charging for a laptop and a tablet or phone simultaneously.

We tested the charger with a MacBook Air M2, an iPad Pro, and an iPhone 15 Pro Max. The MacBook Air charged at full speed when connected alone, and with the iPad and iPhone plugged in, the laptop still received 45W—ample for normal use. The charger also supports USB-C Power Delivery 3.0 and PPS, ensuring compatibility with a wide range of devices including Samsung Galaxy phones and Nintendo Switch.

• Single port: up to 67W (USB-C PD 3.0).
• Dual ports: 45W + 20W (total 65W).
• Supports PPS for Samsung Super Fast Charging.

Travel and Desk Use Experience

The foldable prongs are a game-changer for travel. Unlike chargers with fixed prongs, this one slides easily into the slim pocket of a laptop bag without scratching other items. The compact size also means it won't block adjacent outlets on a power strip—a common annoyance with larger bricks.

For desk use, the charger's low profile keeps your workspace tidy. Pair it with a high-quality USB-C cable, and you have a clean, minimal charging station. While it lacks a built-in cable, the dual ports allow you to charge your laptop and phone from a single outlet, reducing clutter. The charger runs cool even under load, thanks to the efficient GaN technology.

• Foldable prongs protect against damage and save space.
• Compact footprint: won't hog power strip space.
• Stays cool to the touch during extended use.

Comparison with Other Compact Chargers

How does the OntheGo 67W Slim Wall Charger stack up against competitors? Compared to the Apple 67W USB-C Power Adapter, the Satechi charger is significantly smaller and offers two ports instead of one. The Anker 735 charger (65W GaN) is similar in size but slightly bulkier and often more expensive. The Satechi's foldable prongs and sleek design give it an edge for travelers.

One area where the Satechi charger excels is its compatibility with the latest fast-charging standards. It supports PPS, which is essential for Samsung's 45W charging, and it works flawlessly with the iPhone 15 series. For users who need a reliable, compact charger that can handle a laptop and multiple devices, this is a top contender.

• More compact than Apple's 67W charger.
• Dual ports vs. single port on many competitors.
• Supports PPS: better for Samsung devices.

The Satechi OntheGo 67W Slim Wall Charger is a fantastic choice for anyone seeking a compact, powerful, and travel-friendly charging solution. Its GaN design delivers fast charging for laptops, tablets, and phones, while the dual USB-C ports and foldable prongs make it incredibly versatile. Whether you're on the road or at your desk, this charger simplifies your setup without compromising performance. For a complete travel charging kit, consider pairing it with the Dual Smart Outlet for even more power options at home or abroad.
