The Anker 622 Magnetic Battery (MagGo) is a slim, wireless portable charger engineered primarily for iPhone users who want grab-and-go backup power without carrying loose cords. Featuring a nominal 5,000mAh battery capacity, magnetic alignment, and a built-in foldable kickstand, this charger is geared toward commuters, frequent fliers, college students, and office workers using compatible iPhone 16 or 15 devices. Instead of maximizing capacity at the expense of portability, the 622 MagGo prioritizes a pocket-friendly form factor that attaches cleanly to the back of a phone.
In terms of charging functionality, the power bank delivers wireless power directly through its magnetic charging pad, snapping into place for seamless alignment. The 5,000mAh nominal capacity represents the internal cell rating, which serves as a dependable buffer to help keep your phone operational through long work shifts, evening commutes, or travel delays. While wireless transfer and voltage conversion naturally reduce usable delivered energy compared to nominal battery figures, this power bank offers the practical utility needed to prevent a dead battery when you are away from an outlet.
Anker integrates its Advanced Mini Cell Technology into a remarkably slim chassis measuring just 4.13 by 2.64 by 0.51 inches and weighing approximately 0.31 pounds. The Interstellar Gray finish delivers a clean, modern aesthetic that blends well with premium smartphones. One of the standout physical design features is the built-in foldable kickstand, which props your iPhone upright in portrait or landscape orientations. This makes the battery pack equally useful as a portable desktop stand for video calls, hands-free media playback, or desk notifications while your phone receives power.
Operating the Anker 622 MagGo is straightforward, requiring users to simply align the magnetic surface against the back of a compatible iPhone. For recharging the internal 5,000mAh cell, the battery pack includes a 23.6-inch (60 cm) USB-C to USB-C cable that connects to standard USB-C power sources. The charger's slender profile allows it to fit comfortably in a hand alongside the phone, making it easy to continue browsing, texting, or navigating while actively charging without dealing with dangling cables.
Shoppers should keep in mind that this power bank is built specifically for compact convenience rather than high-capacity, multi-device demands. The 5,000mAh nominal rating is not designed to provide multiple recharges or power larger electronics such as laptops or tablets. Additionally, the magnetic wireless attachment is specifically tailored for compatible magnetic iPhone models like the iPhone 16 and 15 series, meaning non-magnetic devices will not experience the same snapping convenience. A wall charging adapter is also not included in the box, so you must provide your own USB-C brick to recharge the pack.
The Anker 622 Magnetic Battery is best suited for iPhone 16 and 15 owners who prioritize lightweight everyday carry and cord-free convenience over heavy battery bricks. If you need a compact backup charger that doubles as an adjustable desk stand for video streaming and daily commuting, this model delivers solid value and reliable build quality backed by a 24-month warranty. Those who require multiple device recharges, high-wattage laptop charging, or multi-port output should look toward higher-capacity power banks instead.
Measuring just 4.13 by 2.64 by 0.51 inches and weighing a lightweight 0.31 pounds, the Anker 622 Magnetic Battery is built specifically for effortless everyday carry. Its ultra-slim profile slips easily into pockets, clutches, or backpacks without creating an awkward bulge, allowing you to use your phone naturally even while the charger remains magnetically attached.
The built-in foldable kickstand adds functional versatility whether you are working at an office desk, relaxing at a coffee shop, or traveling on an airplane. It props your phone upright for hands-free video conferencing or horizontal media viewing, eliminating the need to pack a separate phone stand.
The Anker 622 MagGo is engineered specifically for magnetic-compatible smartphones, with manufacturer documentation explicitly highlighting compatibility with iPhone 16 and iPhone 15 models. The magnetic alignment ensures that the wireless charging coils position properly every time for a secure hold without manual adjustment.
Out of the box, the package includes the Anker 622 Magnetic Battery (MagGo), a 23.6-inch (60 cm) USB-C to USB-C charging cable for recharging the unit, a welcome guide, and Anker's 24-month warranty. Users will need to supply their own USB-C wall adapter to recharge the battery pack from a standard wall outlet.

Cons
- 5,000mAh nominal capacity will not fully recharge most modern iPhones from empty due to normal energy conversion losses in wireless charging
- Magnetic wireless charging is significantly slower than wired USB-C charging, so this is better for gradual top-ups than rapid refueling
- Designed specifically for iPhone 14 and 15 series - Android users and older iPhone owners without compatible magnetic cases cannot take advantage of the snap-on feature
The Anker 621 MagGo is a magnetic wireless power bank with a listed 5,000mAh battery capacity, built specifically for iPhone 14 and iPhone 15 users who want a cable-free charging solution they can snap onto the back of their phone. Anker positions this as an everyday-carry accessory rather than a high-capacity backup battery, and its ultra-slim dimensions of 4.13 x 2.62 x 0.45 inches and weight of just 4.41 oz (0.31 pounds) support that positioning. It's best suited for commuters, students, office workers, and travelers who need a quick top-up during the day rather than enough stored energy to power a phone through an entire weekend trip.
The 5,000mAh listed capacity describes the nominal battery capacity of the internal cells, not the amount of energy guaranteed to reach your iPhone. Wireless charging involves energy conversion losses that are typically higher than wired USB-C charging, so users should expect a meaningful partial charge rather than a full battery refill. The magnetic alignment system helps maintain consistent contact between the power bank's charging coil and the iPhone's receiver, which reduces the misalignment problems that can waste energy or interrupt charging on standard wireless pads. The product description notes that the power bank may reach temperatures between 98-118 degrees Fahrenheit during use when ambient temperature is around 77 degrees Fahrenheit, which Anker states falls within international safety standards.
Build quality centers on the compact, flat form factor that mirrors the footprint of an iPhone. The magnets are described by the manufacturer as ultra-strong, designed to hold firmly enough that you can take selfies, make calls, and use the phone one-handed while the power bank stays attached. The product listing specifically mentions compatibility with iPhone 14 and iPhone 15 models. Users with thick or non-magnetic cases, MagSafe-incompatible cases, or Android phones would not benefit from the magnetic snap-on feature. The black colorway and smooth design keep the unit visually unobtrusive when attached to a phone.
Setup is straightforward. You recharge the Anker 621 MagGo using the included 23.6-inch USB-C to USB-C cable plugged into a USB-C power source - note that no wall charger is included in the box, so you'll need your own adapter. Once charged, you simply align the power bank with the back of a compatible iPhone and the magnets snap it into place, initiating wireless charging automatically. There's no app required and no complex pairing process. For daily routines, the slim profile means you can keep it in a jacket pocket, backpack, or purse and pull it out whenever your battery dips during a commute, between classes, or at a conference.
The biggest limitation of the Anker 621 MagGo is its capacity-to-use-case ratio. At 5,000mAh nominal, wireless charging losses mean the actual energy delivered to an iPhone will be noticeably less than the listed figure. This power bank is not designed for users who need to fully recharge a phone multiple times or who rely on fast wired charging speeds. Wireless magnetic charging is inherently slower than plugging in a USB-C cable, so this is a gradual top-up tool rather than a rapid charger. Additionally, the product description does not list specific wireless charging wattage output, supported Qi certification details, or compatibility with devices beyond iPhone 14 and 15, so users with other phones or devices should look elsewhere.
The Anker 621 MagGo is a strong fit for iPhone 14 and iPhone 15 owners who value the convenience of snap-on magnetic wireless charging and want the smallest, lightest backup battery they can carry daily. It suits commuters who just need enough juice to get through the afternoon, travelers who want a slim emergency reserve for flights or layovers, and anyone who dislikes dealing with cables during their day. Users who need higher capacity, faster wired charging, multi-device support, or Android compatibility should consider a larger or wired power bank instead. The strongest reason to choose this model is its combination of magnetic convenience, ultra-compact size, and Anker's 24-month warranty backing.
The Anker 621 MagGo uses built-in magnets to attach directly to the back of compatible iPhones, specifically the iPhone 14 and iPhone 15 series as listed by the manufacturer. This magnetic alignment ensures the wireless charging coils stay properly positioned, which helps avoid the interrupted or inefficient charging that can happen with non-magnetic wireless chargers when the phone shifts slightly. The snap-on attachment is firm enough that Anker describes single-handed use for selfies and calls while the power bank is attached.
It's important to understand that magnetic attachment and wireless charging capability are not the same as official MagSafe certification. The product listing does not explicitly claim MagSafe certification from Apple, so the Anker 621 MagGo should be understood as a magnetic wireless power bank compatible with iPhone 14 and 15 rather than a certified MagSafe accessory. Users with non-magnetic phone cases or cases that are too thick may find the magnetic hold weakened or the wireless charging connection unreliable. For the best experience, a MagSafe-compatible case or no case at all is typically recommended for magnetic power banks of this type.
At 4.13 x 2.62 x 0.45 inches and 4.41 oz (0.31 pounds), the Anker 621 MagGo is one of the slimmer magnetic power banks available for iPhone users. Anker credits its MiniCell technology for reducing the number of internal components, which contributes to the compact dimensions. The power bank is thin enough to snap onto the back of an iPhone and still fit comfortably in a jeans pocket or small purse compartment, making it practical for everyday carry without adding significant bulk or weight.
For travelers, the slim profile means it takes up minimal space in a carry-on bag or personal item. The 5,000mAh nominal capacity falls well below common airline battery limits, though travelers should always verify current airline and regulatory battery rules before flying. The included 23.6-inch USB-C cable is short enough to coil neatly for storage but long enough to reach a nearby USB-C port for recharging the unit overnight at a hotel or desk.
The Anker 621 MagGo package includes the magnetic battery pack itself, a 23.6-inch (60 cm) USB-C to USB-C cable for recharging the power bank, a welcome guide, and coverage under Anker's 24-month warranty with customer service support. No wall charger or power adapter is included, so buyers will need to use an existing USB-C charger or purchase one separately to recharge the unit. Any standard USB-C power adapter should work for recharging, though the product listing does not specify a recommended input wattage or recharge time.
FAQs
Is 5,000mAh enough to fully recharge an iPhone?
A 5,000mAh magnetic power bank can provide a significant partial charge to most iPhones, but it’s unlikely to deliver a full 0-to-100% recharge. The listed 5,000mAh is the nominal capacity of the internal battery cells. Actual energy delivered to your phone is always lower due to conversion losses during wireless charging. Many iPhone users find this capacity useful as a midday top-up rather than a complete refill.
Do these Anker MagGo power banks work with all iPhones?
No, not all iPhones. The magnetic snap-on attachment requires an iPhone with a MagSafe-compatible magnet ring. The Anker 622 lists compatibility with iPhone 16 and 15 models, while the Anker 621 lists compatibility with iPhone 15 and 14 models. Older iPhones without built-in MagSafe magnets won’t attach securely. A third-party magnetic case might help, but alignment and charging reliability could vary.
What’s the difference between the Anker 622 and the Anker 621?
Both share 5,000mAh of listed capacity and magnetic wireless charging, but they differ in design. The Anker 622 Magnetic Power Bank includes a foldable kickstand for propping up your iPhone during video calls or streaming. The Anker 621 MagGo Power Bank skips the kickstand and focuses on being as compact and lightweight as possible. Your choice depends on whether hands-free viewing or maximum portability matters more to you.
Can I charge these power banks while they charge my phone?
The product specifications for these models don’t explicitly confirm pass-through charging support. Some users report being able to recharge the power bank via USB-C while it wirelessly charges a phone, but this behavior isn’t guaranteed by the manufacturer’s listed features. If pass-through charging is a must-have for your setup, verify this detail directly with Anker’s support before purchasing.
Do these wireless power banks work through a phone case?
Magnetic wireless charging can work through thin, non-metallic cases, but thick cases, metal plates, or wallet-style cases may block the connection or weaken the magnetic attachment. The manufacturer doesn’t list a specific maximum case thickness. If you use a bulky case, you might need to remove it for reliable alignment and charging. MagSafe-compatible cases generally offer the best results.
Are these power banks safe to bring on a plane?
A 5,000mAh power bank at a standard 3.7V nominal voltage would be under 20Wh, which falls well below the typical 100Wh carry-on limit set by most airlines. But the manufacturer doesn’t list a specific Wh rating for either model, so you can’t confirm the exact value from the product page alone. Airlines require lithium battery packs in carry-on luggage, not checked bags. Always check your specific carrier’s current rules before flying. For more Anker options that suit travel, see our picks for Anker power banks with zipper bags.
Is magnetic charging the same as MagSafe?
Not exactly. Magnetic charging refers to using magnets to align a wireless charger with a device. MagSafe is Apple’s specific magnetic and wireless charging system. Both the Anker 622 and Anker 621 are described as MagSafe-compatible battery packs, meaning they’re designed to work with iPhones that support MagSafe. But “MagSafe-compatible” doesn’t necessarily mean Apple-certified. The distinction matters because official MagSafe certification can affect maximum wireless charging speed on certain iPhone models.
