Overview
The Anker 621 Magnetic Battery (MagGo) is a portable power bank designed specifically for users of Apple's iPhone 12 and 13 series. It positions itself in the market as a solution for convenience over raw power, offering a 5,000mAh capacity in an ultra-slim, "snap-on" form factor. By leveraging magnetic attachment, it aims to eliminate the hassle of cables for users needing a quick power top-up throughout the day. Its primary appeal is its integration with the phone, allowing for charging while the device remains fully usable and pocketable.
Key Features
The Anker 621 MagGo focuses on a few core functionalities that define its user experience. Rather than packing in every possible feature, it hones in on portability and ease of use.
Compact Design with MiniCell Technology
One of the standout features is the power bank's slim profile. At just 0.45 inches thick, it's one of the thinner magnetic batteries available. Anker attributes this to its "MiniCell" technology, which it claims reduces the overall size of the battery without compromising power or charging efficiency. This design choice makes it comfortable to hold while attached to an iPhone and allows it to fit easily into a pocket or small bag, even when connected to the device.
Magnetic "Snap and Go" Functionality
The core of the MagGo experience is its magnetic attachment system. Designed exclusively for the iPhone 12 and 13 series (and compatible magnetic cases), the battery features a strong magnetic connection that snaps it firmly onto the back of the phone. This "Charge in a Snap" feature provides a secure hold, ensuring the power bank doesn't easily fall off during normal use. This allows users to charge their device wirelessly without being tethered to a wall outlet or dealing with loose cables while on the move.
For the most reliable magnetic connection, use this power bank with either a caseless iPhone 12 or 13, or with a phone case specifically designed for magnetic charging compatibility. This will ensure a strong attachment and efficient power transfer.
Versatile USB-C Port
While wireless charging is its main draw, the Anker 621 includes a single USB-C port that serves double duty. It functions as an input to recharge the 5,000mAh internal battery, and it also works as a 12W wired output. This means you can use it as a traditional small power bank to charge other devices, like headphones or an Android phone, using a USB-C cable. This versatility adds a layer of utility beyond its primary magnetic charging function.
While the total output is listed as 12W, this corresponds to the stated USB-C output. Users should not expect the fastest available wireless charging speeds, which are typically 7.5W for iPhones with this type of accessory.
Design & Build
The Anker 621 MagGo sports a slender and minimalist design. Its dimensions of 4.13 x 2.62 x 0.45 inches make it a highly portable accessory. The exterior features a PU leather coating, which serves to protect against scratches and scuffs, a thoughtful addition for a device that will be magnetically attached to a phone. The power bank is available in several colors, including Interstellar Gray, Dolomite White, Buds Green, Misty Blue, and Lilac Purple, allowing users to match it to their phone or personal style.
Who It's For
This power bank is tailored for iPhone 12 and 13 users who prioritize convenience and portability. It’s ideal for the individual who needs to get through a long day with guaranteed battery life but doesn’t want the bulk of a traditional high-capacity power bank and cable. Its 5,000mAh capacity is enough to provide a significant boost—roughly one full charge for most compatible iPhone models—making it perfect for daily commutes, short trips, or evenings out.
It is not intended for power users who need to recharge multiple devices or require the fastest possible charging speeds. Instead, it appeals to those who embrace the magnetic accessory ecosystem and want a seamless, integrated way to keep their phone running without interruption.
To recharge the Anker 621 Magnetic Battery, the manufacturer recommends using a power adapter with at least a 12W output for best results. This power adapter is not included in the box.
