If you’ve spent any time looking for a way to kill the cable clutter on your nightstand, you’ve probably seen this little grey box. It’s everywhere. Honestly, at first glance, the Anker 3-in-1 Cube with MagSafe looks like a weighted paperweight or maybe a very expensive Borg cube from Star Trek. But it’s actually become the gold standard for Apple power users who travel.
Most chargers are flat. Or they’re tilted stands that take up half your suitcase. This thing? It’s a literal cube. Small. Dense. Surprisingly heavy. It’s one of those rare gadgets where the build quality actually makes you feel like you didn't just set fire to $150. But let’s be real—$150 for a charger is a lot of money. You could buy a decent pair of noise-canceling headphones for that. So, why are people obsessed with it?

The magic isn't just in the shape. It’s in the certification.
What Most People Get Wrong About "MagSafe Compatible"
There is a massive difference between "magnetic charging" and official, "Made for MagSafe" technology. Most cheap stands you find on Amazon are just Qi chargers with a ring of magnets. They’ll hold your phone, sure. But they cap out at 7.5W. Your iPhone is capable of 15W.
The Anker 3-in-1 Cube with MagSafe is officially certified by Apple. That means it uses the actual proprietary puck. When you snap your iPhone 15 or 16 onto this thing, you get the full 15W fast charging speed. You get the official Apple charging animation. It’s the real deal. If you’re waking up and realizing you forgot to charge your phone, that extra 7.5W of speed is the difference between leaving the house with 30% or 60% battery.
It matters.
And then there's the Apple Watch charger. Most 3-in-1 units use a standard slow charger for the watch. Anker actually integrated the fast-charging module for the Series 7, 8, 9, 10, and Ultra models. If you have an Apple Watch Ultra, you know how long that massive battery takes to fill up on a cheap charger. This cube handles it at top speed. It’s one of the few third-party accessories that doesn't feel like a compromise.
Design Physics: Why the Weight Actually Matters
Have you ever used a light, plastic MagSafe stand? You go to grab your phone in the morning, and the whole stand comes with it. You end up having to use two hands just to check a text. It's annoying.
Anker built this thing to be heavy. It weighs about 14 ounces. That’s nearly a pound. Because it’s so dense, the magnets can be strong without the base lifting off the table. You can peel your phone off with one hand. It stays put.
The hinge is also incredibly stiff. Not "hard to move" stiff, but "this isn't going to flop over" stiff. You can adjust the angle of the MagSafe pad to basically any position. If you’re using StandBy mode in iOS—which converts your iPhone into a bedside clock—this is basically the perfect pedestal for it. You can tilt it so it’s facing your eyes perfectly while you’re lying in bed.
The Pop-Out Watch Shelf
On the side, there’s a little spring-loaded drawer. You push it, and the Apple Watch charger pops out. It’s a clever bit of engineering. When you aren't using it, you tuck it back in, and the footprint of the device stays tiny.
Behind the main MagSafe flap, there’s a dedicated spot for AirPods. It’s a 5W pad. Nothing fancy, but it gets the job done.
Essentially, you are charging your phone, your watch, and your earbuds in a space no larger than a Rubik's Cube. That's the selling point. It’s about reclaimed desk real estate.
Travel Reality: Is It Actually Portable?
I’ve seen reviewers call this the "perfect travel charger." I’d say it’s 90% of the way there.
Because it’s a cube, it fits into the corners of a tech pouch really well. It doesn't have weird arms or brittle plastic bits that feel like they're going to snap off in your backpack. However, because it’s so heavy, you definitely feel it in your bag. If you’re a "one-bag" traveler trying to keep your carry-on under 7kg for an international flight, a pound of charger is a tough sell.
But if you’re a business traveler going from hotel to hotel? It’s a godsend. You pull one cube out, plug in the included 30W USB-C brick, and your entire ecosystem is powered. No more hunting for three different outlets behind a dusty hotel nightstand.

Technical Specifications and Power Flow
- Input: USB-C (requires 30W minimum)
- iPhone Output: 15W Max (Official MagSafe)
- Apple Watch Output: 5W Max (Fast Charging compatible)
- AirPods Output: 5W Max
- Dimensions: Roughly 2.5 x 2.5 x 2.5 inches
One thing to note: Anker includes a 5ft USB-C to USB-C cable and a 30W wall plug in the box. This is actually a big deal because many competitors (cough, Belkin, cough) often use proprietary barrel plugs or don't include the brick at all. If you lose the Anker cable, you can just use any high-quality USB-C cable you have lying around.
The Downside Nobody Talks About
Heat.
MagSafe is notoriously "lossy" when it comes to energy. That energy turns into heat. Because the Anker 3-in-1 Cube with MagSafe is so compact, it doesn't have a lot of surface area to dissipate that heat.
If you are charging all three devices at once, the cube gets warm. Not "fire hazard" warm, but definitely noticeable. Modern iPhones will occasionally pause charging at 80% if they get too hot to protect the battery longevity. If you live in a very hot climate without A/C, you might notice your charging speeds throttling a bit during the summer.
Also, the price. Let’s not dance around it. At $149.95, it is an investment. You are paying for the Apple-certified modules and the metal construction. If you just want something that works and don't care about aesthetics or the 15W speed, you can find plastic alternatives for $40. But they won't feel like this.
Real-World Comparison: Anker vs. Belkin vs. Twelve South
When you look at the premium market, you’re usually deciding between the Anker Cube, the Belkin BoostCharge Pro, and maybe the Twelve South HiRise 3 Deluxe.
The Belkin is a "tree" design. It’s taller and takes up more physical space, but it’s thinner. It’s terrible for travel because the arms don't fold. If you try to put the Belkin in a suitcase, you’re asking for it to break.
The Twelve South is beautiful—wrapped in vegan leather—but it’s also a fixed stand.
The Anker Cube wins on versatility. It is the only one that disappears when you aren't using it. It’s also the only one that feels like it could survive a drop off a table.
Why This Matters for iPhone 16 Users
With the latest iPhone releases, Apple has doubled down on MagSafe capabilities. The magnets are precise, and the software integration for "StandBy" is more robust than ever. Using a certified charger like the Anker Cube ensures that the software correctly recognizes the charger.
Some "knock-off" chargers cause the screen to flicker or the touch sensitivity to go wonky while charging because of poor shielding and "dirty" power delivery. You don't get that here. The power delivery is clean, which is exactly what you want when you’re plugging in a $1,200 smartphone.

Final Verdict: Who Should Buy This?
Honestly, this isn't for everyone. If you only have an iPhone and you don't own an Apple Watch, this is a waste of money. You’re paying for two charging modules you won't use.
But if you are in the "Apple Trinity"—iPhone, Watch, AirPods—and you hate wires, this is probably the best accessory you can buy. It solves the clutter problem instantly. It’s built to last a decade. It’s one of those "buy it once, cry once" purchases.
Actionable Next Steps
If you’re ready to pull the trigger on an Anker 3-in-1 Cube with MagSafe, here is how to make sure you get the best experience:
- Check your current brick: While Anker provides a 30W charger, if you plan on using your own multi-port charger, ensure it can output at least 30W to a single port. If you under-power it, the watch or AirPods might not charge at all.
- Case Compatibility: Ensure your iPhone case is "MagSafe Compatible." If the case is too thick and doesn't have the internal magnets, the phone will slide right off the cube's tilted face.
- Placement: Put it on your nightstand or your primary workspace. Because it’s so heavy, it’s not something you want to be moving from room to room every day. Pick a spot and let it live there.
- Cleaning: The grey finish is a bit of a dust magnet. A quick wipe with a microfiber cloth once a week keeps the silicone charging pads grippy.
The market is flooded with cheap chargers that promise the world and deliver slow, overheating results. The Anker Cube is the opposite. It’s a dense, over-engineered piece of kit that does exactly what it says on the box. It’s expensive, yes. But in a world of disposable plastic tech, it feels like something actually worth owning.
