Why We Picked the Anker 3-in-1 Cube
Charging an iPhone, Apple Watch, and AirPods usually means three separate chargers, three cables, and a cluttered nightstand or desk. The Anker 3-in-1 Cube folds all three into a single palm-sized block that unfolds into a stand — MagSafe-certified for up to 15W iPhone charging, with a spring-loaded watch charger and a fold-out shelf for earbuds. At $89.99 it isn’t cheap, but with 3,351 ratings at 4.5 stars, over 1,000 bought in the past month, and a genuine Amazon buy box (ships from and sold with Amazon fulfillment), it’s a well-established pick rather than an unproven newcomer — and Anker’s track record backs it up.
What Owners Actually Say
The recurring theme across verified reviews is that the design earns its keep. One reviewer (MS) praised how it “folds up easily into a compact cube when not in use” and highlighted the grippy, weighted base that keeps it stable on a desk or nightstand. Another (DarkWarwulf) measured real-world charging speed — 50% on an iPhone 14 Pro Max in 47 minutes, and an Apple Watch Series 7 to about 75% in 45 minutes — and called it his top travel accessory for consolidating chargers into one set. A frequent complaint that’s actually a compliment in disguise: several reviewers admit the price stings (“at $150 I feel like this is WAY over-priced”) but say they bought it anyway because Anker’s reliability made the spend feel safe.
One Thing to Check
The magnetic phone dock, watch charger, and earbud shelf don’t age identically. One reviewer (Tony F.) who tested it for about a week flagged that “the one part that feels a little flimsy in comparison to the rest is the watch charger” — the pop-out mechanism feels less durable than the rest of the unit, and he suspected it could be the first part to fail over time. The same reviewer also measured the earbud charging bay running noticeably warm — “almost hot” — when all three devices charged simultaneously, worth keeping an eye on if you routinely charge everything at once overnight. It’s also heavier than a typical single-device charger, which a few reviewers said makes it less ideal for tossing in a light travel bag despite being marketed as portable.
Pros and Cons
Pros:
- Genuine MagSafe certification with up to 15W iPhone charging
- Charges iPhone, Apple Watch, and AirPods simultaneously from one compact unit
- Folds flat for travel; unfolds into an adjustable-angle stand (up to 60°)
- Strong, secure magnetic hold — works even through some phone cases
- Comes bundled with a 30W wall charger and USB-C cable
Cons:
- Watch-charger mechanism feels less durable than the rest of the build, per multiple owners
- Can run noticeably warm at the earbud bay when charging all three devices at once
- Heavier than simpler chargers, which cuts against its “travel-ready” pitch for some users
- Premium price relative to basic 3-in-1 chargers
FAQ
Does it charge Apple Watch Ultra models?
Yes — reviewers specifically confirm Ultra and Ultra 2 charge reliably despite some conflicting claims elsewhere online.
Will it work with a case on my phone?
It’s compatible with MagSafe-friendly cases; thick, non-magnetic cases (like OtterBox Defender) or cases with metal attachments, cards, or pop grips can interfere with charging, per Anker’s own documentation.
Does it charge the phone quickly?
It supports up to 15W wireless charging on compatible iPhone models — reviewers report roughly 50% charge in under an hour, in line with standard MagSafe speeds.
