AI Verdict
A 5,000mAh MagSafe-compatible power bank for iPhone 12-16 series, delivering around 3,000-3,500mAh at 7.5W wireless charging.
This power bank is a situational fit because its 4.41 oz weight and 0.45 inch thickness make it exceptionally portable for quick top-ups on MagSafe-compatible iPhones. However, its 7.5W wireless charging speed and actual usable capacity of 3,000-3,500mAh mean it's not for users needing fast, full charges or extensive power delivery.
If you need faster charging or more capacity, look for power banks with 15W Qi2 certification and 10,000mAh or higher battery capacities.

Pros
- Measures 4.13 × 2.62 × 0.45 inches and weighs 4.41 oz, making it highly portable.
- Features ultra-strong magnets for secure attachment to MagSafe-compatible iPhones.
- Automatically begins charging when snapped onto an iPhone, without needing a button press to initiate power delivery.
- Includes a USB-C port for recharging the power bank and for wired charging other devices.
- Comes with a 23.6 inch (60 cm) USB-C to USB-C cable.
Cons
- Wireless charging speed is limited to 7.5W, which is slower than the 15W MagSafe standard.
- Actual usable capacity is approximately 3,000-3,500mAh, not the advertised 5,000mAh, due to energy conversion losses.
- The power bank and connected phone can reach temperatures between 98-118°F during wireless charging, potentially slowing the charge.
- May not provide a full charge for larger iPhone models, with some users reporting only 40% charge on an S24 Ultra.
- Lacks a built-in kickstand, a feature found on some competing magnetic power banks.
Dimension Scores
Wireless charging is limited to 7.5W, which is half the speed of 15W MagSafe chargers and can be slower than wired alternatives.
Anker's MiniCell technology and strong magnets contribute to a compact and secure design, with a semi-rubberized surface for grip.
It is specifically designed for MagSafe-compatible iPhone 12-16 series, limiting its universal application to other phone brands or non-MagSafe cases.
At 4.13 × 2.62 × 0.45 inches and 4.41 oz, it's exceptionally small and light, fitting easily into pockets or small bags.
Best For
- iPhone 12-16 series users needing a temporary power boost during short outings.
- Individuals prioritizing minimal bulk and weight for pocket or small bag carry, at 4.41 oz and 0.45 inches thick.
- Users seeking a simple, cable-free charging experience for MagSafe-compatible iPhones.
Not Recommended For
- Users expecting rapid wireless charging speeds, as it delivers 7.5W wirelessly, not 15W.
- Those requiring a full charge for larger iPhone models or multiple device charges from a single power bank.
- Android phone users, as its magnetic attachment and primary wireless charging are designed for MagSafe-compatible iPhones.
Watch Out For
- The real-world power delivered to your phone is closer to 3,000-3,500mAh, despite the 5,000mAh internal battery, due to energy loss during wireless transfer.
- Wireless charging is capped at 7.5W, meaning your iPhone will charge slower than with a 15W MagSafe charger or a faster wired connection.
- The device and your phone can get noticeably warm during wireless charging, with temperatures reaching up to 118°F, which can trigger thermal throttling and slow down charging.
- If you have a thick phone case (over 2.5 mm), the magnetic attachment might not be strong enough, or wireless charging might not work reliably.
- It might only provide a partial charge for larger iPhone models; for example, one user reported only a 40% charge on an S24 Ultra.

What Buyers Say
Many users found the Anker 621 MagGo to be smaller and lighter than expected, making it convenient for quick power boosts, but the actual charge delivered often fell short of a full phone charge. The 7.5W wireless charging speed was a recurring point of discussion, with some noting it felt slow, and the device getting warm during use was a common experience. The magnetic attachment, however, was consistently praised for its strength and reliability.
“I bought this thinking 5000mAh would easily charge my iPhone 15 Pro, but it barely got me to 60% and felt like a hot potato the whole time. The magnet is strong though, so at least it didn't fall off.”
Common Praise
- The power bank's 4.13 × 2.62 × 0.45 inch dimensions make it very compact and pocketable.
- It weighs only 4.41 oz, adding minimal bulk when attached to a phone.
- The magnets provide a strong attachment to MagSafe-compatible iPhones, preventing accidental disconnections.
- Charging starts automatically when the power bank snaps onto the phone, without needing to press a button.
Common Complaints
- The 7.5W wireless charging speed is noticeably slower than other charging methods, sometimes struggling to keep up with active phone use.
- Real-world testing showed the usable capacity to be around 3,000-3,500mAh, not the full 5,000mAh, leading to incomplete phone charges.
- Both the power bank and the iPhone can become warm or hot during wireless charging, which can be uncomfortable and may reduce charging efficiency.
- It often fails to provide a full 0-100% charge for larger iPhone models, serving more as an emergency top-up.
Ownership Tips
- The power bank consistently gets warm, sometimes hot, during wireless charging, especially during extended use.
- The actual percentage of charge delivered to an iPhone is often less than expected, typically providing a partial charge rather than a full one.
- The magnetic attachment remains secure even with daily handling and movement, holding the phone firmly.
- The power button primarily serves to check the battery level indicators; charging initiates automatically upon magnetic connection.
- Using the USB-C port for wired charging provides a faster power delivery than the wireless MagSafe connection.
Frequently Asked Questions
What is the actual usable battery capacity?
Due to energy conversion losses inherent in power banks, the actual usable capacity delivered to your device is typically around 3,000-3,500mAh, not the full 5,000mAh internal capacity.
How fast does it charge my iPhone wirelessly?
This power bank charges MagSafe-compatible iPhones wirelessly at a maximum speed of 7.5W. This is slower than the 15W speed offered by some other MagSafe chargers.
Does the power bank get hot during use?
Yes, it's normal for the power bank and your phone to get warm, potentially reaching 98-118°F, during wireless charging due to energy transfer.
Will it fully charge my iPhone?
It may not provide a full charge for larger iPhone models, especially those with larger batteries; it's more suited for topping up your phone's battery.
Can I charge other devices using the USB-C port?
Yes, the USB-C port can be used to charge other devices with a compatible USB-C cable, offering a wired charging option.
Does it have a built-in kickstand?
No, this specific Anker 621 model does not include a built-in kickstand.
Buying Guide
When looking at portable chargers, you need to understand that the advertised battery capacity (mAh) isn't what your phone actually gets. There's always some energy lost in the transfer. Also, wireless charging is super convenient, but it's often slower than plugging in directly. Magnetic attachment is great for iPhones, but make sure your case isn't too thick.
battery_capacity (5,000mAh)
This number tells you the raw energy stored in the power bank. However, due to conversion inefficiencies, your phone will only receive about 60-70% of this, so a 5,000mAh bank might only give your phone 3,000-3,500mAh of usable power, which might not be a full charge for larger phones.
Wireless Charging Speed (7.5W)
This indicates how quickly your phone will charge wirelessly. 7.5W is considered a standard, but slower, wireless charging speed. Faster MagSafe chargers can deliver 15W, so this one will take longer to top up your device.
MagSafe-Compatible
This means it uses magnets to snap onto the back of iPhone 12 series and newer models. It ensures a secure connection and proper alignment for wireless charging, but you'll need a MagSafe-compatible case if you use one.
Alternatives
If you need faster charging, look for power banks explicitly stating 15W Qi2 wireless output. For more charges or larger devices, consider options with 10,000mAh or higher capacity, potentially with a built-in kickstand for added utility.
