Anker Prime 67W vs 100W: Which Charger Actually Stays in the Outlet?

If you are choosing between the Anker Prime 67W vs 100W, you want to know which one fits your life. The Anker Prime 67W is a pocket-sized hero for MacBook Air users and light travelers. 

However, the Anker Prime 100W is the better pick for power users who need to charge a MacBook Pro and a phone at the same time without any slowdowns. In this guide, we compare their size, charging speeds, and real-world heat performance to help you spend your money wisely. Don't let your gear hold you back—find the right balance between portability and pure speed.

Key Takeaways: The Cheat Sheet

Size Matters: The 67W is about the size of a golf ball. The 100W is about 20% larger and noticeably heavier.

Laptop Speed: The 67W is perfect for a MacBook Air or a 14-inch Pro. The 100W is needed for the 16-inch Pro.

Port Sharing: When you plug in two things, the 67W drops fast. The 100W can still give a laptop 65W while fast-charging a phone.

Heat: Both get warm, but the 100W handles heat better during long work sessions because it has more surface area.

Travel Friendly: The 67W stays in weak wall outlets better. The 100W might sag if the outlet is old.

Price Gap: You usually pay about $20 to $30 more for the 100W version.

Future Proof: The 100W will work with almost any USB-C device you buy in the next five years

Comparison Table: Short but real

Size and Build: The Pocket Test

The first thing you notice when holding the Anker Prime 67W vs 100W is the weight. The 67W model feels like a dense little nugget. It’s so small that it fits in the tiny "coin pocket" of my jeans.

The 100W model is longer. It looks like a thick stick of butter. Because it’s longer, the center of gravity is further from the wall. If you are in a hotel with "loose" outlets that have been used a million times, the 100W might start to tilt down. Anker fixed this by making the prongs very sturdy, but physics is still physics.

The Winner for Portability: Anker Prime 67W.

Charging Speed: How Fast is Fast?

Let’s look at the math, but keep it simple.

• Anker Prime 67W: Can charge an iPhone 15 to 50% in about 25 minutes. It can also fully power a MacBook Air at its max speed.

• Anker Prime 100W: Can do everything the 67W does, but it can also "fast charge" the big 16-inch MacBook Pro or a gaming handheld like the Steam Deck at full tilt.

The real difference shows up when you plug in three things at once. On the 67W model, the power gets split up. If you have a laptop and a phone plugged in, your laptop might only get 45W. That’s enough to keep it alive, but it won’t "fast charge" while you work.

On the 100W model, you can have a laptop at 65W and a phone at 30W at the same time. Both devices will charge very quickly. This is the biggest reason to go for the 100W.

Real User Experience: The Handshake Delay

One thing no one tells you about these smart chargers is the "re-start" dance. When you have one phone plugged in and you plug in a second one, the power cuts out for a split second. This is the charger "talking" to the devices to see how much power each one needs.

In my testing, the Anker Prime 100W feels a bit smarter here. It uses "PowerIQ 4.0," which adjusts the power more often. The 67W does this too, but if you plug in a very low-power device (like a watch), it sometimes gets confused and gives the watch too much or the laptop too little for a minute.

Heat Performance: Does it get hot?

Yes. Both of these use "GaN" tech, which helps them stay cooler than old-style chargers. But they are still pushing a lot of power through a tiny box.

When I used the 67W to charge my laptop from 0% to 100%, the brick got hot enough that I wouldn't want to hold it for long. It wasn't "burning" hot, but it was "very warm coffee" hot.

The 100W model actually stayed a bit cooler during the same test. Why? Because even though it's more powerful, it has a bigger body to let the heat out. If you hate hot tech, the 100W is surprisingly the "cooler" choice for medium tasks.

Which one should you buy?

Check the Anker Prime 67W if:

• You mostly use a MacBook Air or a tablet.

• You travel with only a carry-on bag and every gram counts.

• You usually charge your big devices one at a time.

• You want to save some cash for a better cable.

Check the Anker Prime 100W if:

• You have a 14-inch or 16-inch MacBook Pro.

• You are a "power user" who needs a laptop, phone, and tablet all charged by lunch.

• You play games on a ROG Ally or Steam Deck.

• You want one charger that will be useful for years, even if you buy a bigger laptop later.

Final Verdict

The Anker Prime 67W vs 100W choice comes down to one question: How many "big" things do you need to charge at once?

For most people, the 67W is plenty. It’s tiny, it’s cute, and it works. But for me? I’ll take the 100W. Having that extra "headroom" means my laptop never complains about slow charging, even when I'm editing video and charging my phone at the same time.
