Overview

The Anker MagGo Power Bank (5K, Ultra-Slim) is a Qi2-compatible magnetic battery pack launched by Anker in 2025. With a modest 5000mAh capacity but an impressively slim profile of roughly 10mm, it prioritizes portability over raw capacity. It works seamlessly with iPhone 12 and later MagSafe models, as well as Qi2-compatible Android smartphones. What sets this power bank apart is its ultra-slim design, which allows you to keep it attached to your phone while still using the device one-handed. No more bulky bricks weighing down your pocket. A USB-C port also supports wired fast charging at up to 20W, giving you flexibility when you need a quick top-up.

Connectivity & Compatibility

Wireless Charging: Qi2 standard with up to 15W output. Works with iPhone 12 through 17 series and Qi2 Android phones (Galaxy S25 series, etc.) via magnetic attachment. Wired Charging: USB-C port supports Power Delivery input/output up to 20W. Use the same port to charge the battery pack itself or to charge your phone via cable. Compatible Devices: iPhone 12/13/14/15/16/17 series, Qi2 Android smartphones, AirPods with wireless charging case, and other Qi-compatible devices. Note: Thick or non-MagSafe cases may reduce magnetic hold and wireless charging stability. Apple original or MFM-certified cases are recommended.

Product Info

The Anker MagGo Power Bank (5K, Ultra-Slim) launched in May 2025. It retails for around $34.99 (or ¥4,990 in Japan) and is available from Anker's official store and major retailers like . Anker provides an 18-month warranty (extendable with product registration). The package includes the battery, a USB-C to C cable (approx. 0.6m), and a manual. This product sits in the entry-to-mid tier. The 5000mAh capacity is tailored for emergency top-ups rather than all-day power. However, its ultra-slim build and Qi2 support make it a compelling choice for users who value portability over sheer capacity.

Best Use Cases

Daily commuters and office workers: If you often find your phone battery running low by mid-afternoon, this power bank is a lifesaver. It slips into a shirt pocket or small bag and provides a quick boost without adding bulk. Heavy gamers or video streamers may need a larger capacity, though. MagSafe enthusiasts: If you already use MagSafe cases or accessories, the magnetic attachment feels natural and convenient. Just snap it on and go. Android users with non-Qi2 phones will be limited to 7.5W wireless charging, so check compatibility first. * Light travelers: For short trips or day outings, 5000mAh is enough for one full phone charge. It's perfect for a flight or a café work session. But if you need to charge a tablet or laptop, look for a higher-capacity model.

Things to Consider

Limited capacity: 5000mAh provides roughly one full charge for most smartphones. Heavy users or those on long trips should consider the 10K version. Wireless speed depends on device: iPhone 12-14 series max out at 7.5W wirelessly. Full 15W Qi2 speed requires iPhone 15 or later, or a Qi2 Android phone. Case compatibility: Thick or non-MagSafe cases can weaken the magnetic hold and cause charging interruptions. Stick with slim, MagSafe-compatible cases. Alternatives: The Anker 621 Magnetic Battery (MagGo) offers a built-in kickstand but is slightly thicker. Belkin's BoostCharge Magnetic Power Bank 5K has a premium design but lacks Qi2 on some models, making the Anker MagGo a better choice for faster wireless charging.
