Anker MagGo 10K Slim Review: The $80 Magnetic Power Bank iPhone Users Keep in Their Pocket
Verdict: Worth it — if you have a MagSafe-compatible iPhone, this is the magnetic battery pack to beat.
Why we noticed it
Magnetic battery packs are everywhere now, but most are either too weak (7.5W trickle charging) or too bulky to carry daily. Anker’s MagGo 10K Slim caught our attention because it solved both: Qi2-certified 15W wireless charging in a package under 0.6 inches thick. TechRadar’s testing named it one of the fastest MagSafe power banks it has tried, and on Amazon it holds a 4.4-star rating and sits in the top 15 best sellers among portable power banks.
What it does
It’s a 10,000mAh magnetic power bank that snaps onto the back of any MagSafe-compatible iPhone (12 series and later, including the iPhone 17 lineup) and charges wirelessly at up to 15W — no cables needed. Because it’s Qi2 certified, it’s roughly twice as fast as the older generation of magnetic chargers that topped out at 7.5W.
What we like
- Slim profile: At about 4.09 × 2.78 × 0.58 inches and 7 ounces, it’s genuinely pocketable for a 10,000mAh pack — noticeably slimmer than the earlier MagGo models.
- Strong magnetic grip: Reviewers consistently report the magnets hold firmly. You can slide the phone in and out of a pocket without the charging cycle breaking.
- 30W wired USB-C port: When you want speed, plug in — it delivers up to 30W wired output to your phone and refills itself at up to 30W.
- Premium build: Metal frame, liquid-silicone charging surface that resists fingerprints, and Anker says the shell uses 75% recycled materials.
The catch
- Usable capacity is lower than the label: Like all wireless power banks, charging losses mean you get roughly 5,500–6,500mAh of usable charge — about one full iPhone charge plus a bit more, not the 1.8+ charges the 10,000mAh figure suggests.
- It’s premium-priced: At a $79.99 list price, it costs roughly double the generic 7.5W magnetic packs.
- iPhone-only: Designed for MagSafe iPhones; Android phones with magnetic cases can work, but Anker explicitly says it isn’t for Pixel phones.
Who it’s for / who should skip it
For: iPhone 12–17 owners who want cable-free top-ups through the day — commuters, travelers, and anyone tired of hunting for outlets. A top-15 best seller ranking suggests it has real fans.
Skip: If your phone doesn’t support MagSafe, or you want maximum capacity per dollar (a basic wired 20,000mAh bank charges faster for less money).
Price
List price $79.99, and it regularly drops to the $55–65 range during Amazon sale events.

How we evaluated it
This is a researched review, not hands-on testing. We cross-checked the product specs against Anker’s official listings, TechRadar’s tested review, Android Authority’s deal coverage, and aggregate buyer feedback (4.4-star average, thousands of ratings, top-15 category best-seller rank) to separate genuine strengths from marketing claims.
3 alternatives
- Anker 633 Magnetic Battery (A1641): The older classic — thicker, 7.5W charging, but often under $50.
- INIU Qi2 10,000mAh Magnetic Power Bank: A cheaper Qi2 alternative frequently around $50, with a built-in USB-C cable.
- Anker Nano Power Bank (USB-C): If cables don’t bother you, this wired stick is smaller and cheaper for the same capacity.
FAQ
Does it work with a case on?
Yes, as long as the case is MagSafe-compatible (or has a magnetic ring).
Will it charge my AirPods?
Only if the AirPods case fully covers the charging coil — center it and press the button to activate.
Why does charging pause at 80%?
That’s your iPhone’s own thermal management (iOS 17+), not the battery pack. It resumes when the phone cools.
Final verdict
The Anker MagGo 10K Slim is worth it for MagSafe iPhone users who want a pocketable, genuinely fast magnetic charger. It’s priced like a premium accessory because it performs like one.
