Detailed Product Reviews
1. Anker Prime 100W USB C GaN Charger
Pros
- Extremely compact and lightweight
- Intelligent power distribution for efficient charging
Cons
- Premium price point
- Only one USB-A port
The Breakdown
Market research indicates the Anker Prime 100W is the current benchmark for travel chargers, shrinking previous GaN designs even further. It delivers a full 100W from a single USB-C port, enough for a 16-inch MacBook Pro, and cleverly allocates power when other devices are connected. Its foldable prongs and minimalist design make it exceptionally easy to pack.
Key Specs:
- Ports: 2x USB-C, 1x USB-A
- Max Output: 100W (Single Port)
- Dimensions: 1.5 x 1.7 x 2.4 inches
- Weight: ~6.7 oz
The Community Verdict
Users consistently praise its impressively small size and ability to replace multiple chargers without getting hot. The consensus is that while it’s an investment, its performance and convenience justify the cost for frequent travelers. Some users note that with all three ports in use, the primary USB-C port’s output drops, which is standard behavior but important to be aware of.
Dealbreaker?
Skip this if you need to power multiple high-draw USB-C devices (like two laptops) at their maximum speeds simultaneously.
2. SHARGE 6-in-1 Charging Station 100W GaN
Pros
- Unmatched versatility with three AC outlets
- Detachable power cord is travel-friendly
Cons
- Significantly bulkier than traditional chargers
- AC outlets have a combined power limit
The Breakdown
The SHARGE redefines the travel charger by integrating three AC outlets, transforming it into a compact power strip. This is less a simple wall charger and more a complete power solution for a hotel desk or conference room. It still provides 100W of GaN power through its USB ports, making it a true all-in-one device for those who carry more than just USB-powered gear.
Key Specs:
- Ports: 2x USB-C, 1x USB-A, 3x AC Outlets
- Max Output: 100W (USB Ports)
- Dimensions: 4.7 x 1.9 x 1.7 inches
- Weight: ~10.4 oz
The Community Verdict
Owners report that it’s a game-changer for simplifying their travel kit, especially for powering camera batteries, electric shavers, or other proprietary chargers alongside their laptop and phone. The main critique is its size and weight, which is a clear trade-off for its incredible utility. It’s not a pocket charger, but it’s a brilliant backpack charger.
Dealbreaker?
Skip this if your only goal is maximum portability and you only charge USB-C and USB-A devices.
3. Anker 100W USB C Charger Block (GaN II)
Pros
- Excellent performance for the price
- Often available at a discount compared to newer models
Cons
- Larger than the newer Anker Prime model
- Uses older generation GaN technology
The Breakdown
This charger, often referred to as the Anker 736, was a top recommendation for years and remains a fantastic option. It features Anker’s GaN II technology, which is still highly efficient, and offers the same versatile port layout as its newer sibling. While it’s been surpassed in size, it hasn’t been surpassed in reliability, making it a smart buy, especially when on sale.
Key Specs:
- Ports: 2x USB-C, 1x USB-A
- Max Output: 100W (Single Port)
- Dimensions: 2.6 x 1.2 x 2.2 inches
- Weight: ~7 oz
The Community Verdict
The long-term consensus is overwhelmingly positive, with users citing its durability and consistent performance. Many who own it see no compelling reason to upgrade to the newer, smaller models unless pocketability is their absolute number one priority. It’s regarded as a workhorse that simply gets the job done.
Dealbreaker?
Skip this if you absolutely must have the smallest and lightest charger on the market.
4. MOMAX Universal Travel Adapter 100W GaN
Pros
- True all-in-one global charging solution
- Generous 5-port layout (3x USB-C, 2x USB-A)
Cons
- Bulky and heavy compared to non-adapter chargers
- Mechanical sliders can be a potential point of failure
The Breakdown
The MOMAX charger solves a different problem: it eliminates the need for a separate travel adapter. By integrating sliders for US, EU, UK, and AU plugs directly into a powerful 100W GaN charger, it becomes the only power device many international travelers need. Its five ports provide ample connectivity for a full suite of electronics.
Key Specs:
- Ports: 3x USB-C, 2x USB-A
- Max Output: 100W (Single Port)
- Dimensions: 3.4 x 2.2 x 2.1 inches
- Weight: ~8.8 oz
The Community Verdict
Global travelers report this device is a lifesaver, decluttering their bags and simplifying hotel room setup. The convenience of the built-in adapter system is its most praised feature. Some users mention its weight and bulk can make it unstable in worn-out wall sockets, a common issue for all-in-one adapters.
Dealbreaker?
Skip this if you primarily travel domestically, as you’d be carrying extra bulk and complexity for no reason.
Buying Guide: How to Choose the Right Charger
Choosing the best 100W GaN charger for travel comes down to three factors:
- 1. Port Configuration: Count your devices. If you travel with a modern laptop, phone, and watch, a charger with at least two USB-C ports is essential. If you still have legacy USB-A devices, ensure your chosen charger has a port for them.
- 2. Portability: Define what ‘travel’ means to you. For the backpacker where every ounce matters, the Anker Prime is the clear winner. For the business traveler setting up a mobile office, the SHARGE’s added bulk is a worthy trade-off for its utility.
- 3. Primary Use Case: Are you a globetrotter or a domestic road warrior? If you frequently cross borders, the integrated adapter of the MOMAX is invaluable. If not, a more compact, dedicated charger like the Anker models is a more efficient choice.
Frequently Asked Questions (FAQ)
What is a GaN Charger?
GaN stands for Gallium Nitride, a semiconductor material that is more efficient than traditional silicon. This allows chargers to be built smaller, run cooler, and handle more power without increasing in size, making them ideal for travel.
Will a 100W charger damage my phone?
No. Modern chargers and devices use communication protocols like USB Power Delivery (PD). The charger will only supply the maximum amount of power that the connected device, like your phone, safely requests.
Do I really need 100W for travel?
If you travel with a powerful laptop (like a MacBook Pro 14/16″, Dell XPS, etc.), 100W is ideal for charging it at full or near-full speed, even while in use. It also provides enough overhead to charge your phone and other accessories at the same time without significantly slowing down the laptop’s charging.
