Anker 100W USB C Charger Block (GaN II) - Compact 3-Port Fast Charger

In this review of the Anker 100W USB C Charger Block (GaN II), the bottom line is simple: this compact three-port wall charger is for power users who need laptop-class power in a pocketable travel brick. It stands out because it can deliver up to 100W from a single USB-C port while still fitting 34% smaller than an original 96W MacBook power brick, making it a strong choice for anyone who carries a laptop plus phone or tablet and wants fast charging without multiple bulky adapters.

Key Features

• 100W single-port charging: When using one USB-C port the charger can deliver up to 100W, allowing laptops like a MacBook or Dell XPS to charge rapidly from a single compact adapter.
• Three-port multitasking: The block can power three devices at once with distributed outputs, so a laptop, phone and earbuds can all charge from one outlet for travel or desk use.
• GaN II technology: The upgraded GaN II internals increase operating frequency and use a stacked design to reduce size without sacrificing power handling or efficiency.
• Compact dimensions: At roughly 2.64 in x 1.24 in x 2.24 in the unit is noticeably smaller than many OEM laptop bricks, saving bag space and making it easier to carry.
• Safety certifications: The charger meets safety standards with IEC62368 certification and a V0 fireproof casing, so it is built with common protection and thermal design in mind.
• Included support: Each purchase includes the Anker 736 Charger (Nano II 100W), a welcome guide and an 18-month warranty with Anker customer service.

Who It's For

The Anker Nano II 100W is ideal for frequent travelers, remote workers and students who need to charge a laptop plus mobile devices from a single wall outlet. Its high single-port output makes it suitable for users who own USB-C laptops such as MacBook and Dell XPS models as well as power-hungry tablets like iPad Pro.

People who only need one low-power charger or who want a battery pack rather than a wall adapter should look elsewhere. Also, users seeking an adapter with redundant proprietary ports or built-in cables may find a simpler dedicated charger more convenient.

Pros & Cons

Pros

• High 100W output lets a laptop charge quickly from one USB-C port.
• Three-port layout charges laptop, phone and accessories simultaneously for desk or travel convenience.
• Small, lightweight GaN II design saves bag space compared with many OEM bricks.
• Solid build quality and sensible safety certifications give confidence during use.

Cons

• Some users report intermittent issues with USB-C ports failing in rare cases, so longevity can vary.
• When all ports are used at once, per-port power is reduced, so maximum laptop charging requires single-port use.

Specifications

Our Verdict

The Anker 100W USB C Charger Block (GaN II) is a practical pick for anyone who wants laptop-level charging in a much smaller package than OEM bricks. It delivers fast single-port charging, sensible multi-device power distribution for travel and desk use, and robust safety basics. Given its compact size and versatility, it represents good value for users who need a single charger for a laptop and mobile devices, provided they accept the tradeoff of reduced per-port power when all three ports are active.

Frequently Asked Questions

Can this charger power a 16-inch laptop?
Yes, when using a single USB-C port it can provide up to 100W, which will charge many 13 in and some 15 in laptops; check your laptop power requirements for 16 in models.

Will it charge three devices at full speed?
No, power is shared across ports: triple-port mode limits per-port output (45W, 30W, 18W), so full laptop speeds require single-port use.

Is the charger safe to leave plugged in overnight?
Yes; it meets IEC62368 safety standards and has a V0 fireproof casing, though slight warming during high-power charging is normal.
