AI Verdict
This 5,000mAh MagSafe-compatible power bank offers a partial charge for iPhones 12-16, prioritizing compact size and magnetic attachment over fast wireless charging.
This power bank is a situational fit for iPhone users who need a small, magnetically attaching battery for a partial charge. Its 5,000mAh capacity and 7.5W wireless output mean it's best for extending battery life rather than fully recharging a device, especially given the real-world capacity delivery is lower than advertised.
If you need faster wireless charging or a full phone charge, look for a MagSafe power bank with Qi2 15W certification and a 10,000mAh capacity.

What Buyers Say
Many users appreciate the compact size and the strong magnetic hold of the Anker 621, making it convenient for quick power boosts on the go. However, a recurring complaint is that the actual charge delivered to the phone is significantly less than the advertised 5,000mAh, often only providing a partial charge. Users also frequently mention the device getting warm during wireless charging, and some express desire for faster charging speeds than the 7.5W it offers.
“Ugh, this thing barely gives my iPhone 14 Pro Max half a charge and it gets kinda toasty, but at least it sticks on there like glue and fits in my tiny purse. I just wish it charged faster for what it is.”
Common Praise
- The magnetic attachment is strong and keeps the power bank securely on the iPhone.
- Its compact and slim design makes it easy to carry in a pocket or small bag.
- The convenience of snapping it onto the phone without cables is a major plus.
- It's effective for providing a quick battery top-up when away from an outlet.
Common Complaints
- The 5,000mAh capacity doesn't translate to a full phone charge, often only providing 50-70% of a charge for an iPhone.
- The power bank gets noticeably warm during wireless charging.
- Wireless charging speed at 7.5W is considered slow by some users, especially compared to wired options.
- Some users wish it had a built-in kickstand for media viewing.
Ownership Tips
- After a few weeks, you realize it's more of a battery extender than a full charger.
- The magnetic connection holds up well even with daily attachment and removal.
- The warmth during charging becomes a familiar characteristic, not necessarily a defect.
- The included USB-C cable is handy for recharging the power bank itself, but you'll likely use your phone's cable for faster wired charging if needed.
Frequently Asked Questions
How many full charges can this provide for my iPhone?
Due to efficiency losses in wireless charging, this 5,000mAh power bank typically provides about 0.6 to 0.8 of a full charge for most modern iPhones, depending on your phone's battery size and usage during charging.
Does it work with phone cases?
It works with MagSafe-compatible cases. If your case is not MagSafe-compatible, the magnetic attachment will be weak or non-existent, and wireless charging may not function correctly.
Is it normal for the power bank to get warm?
Yes, Anker states that slight heating due to efficiency losses in the conversion circuit is normal during wireless charging. If it becomes excessively hot, discontinue use.
What is the wireless charging speed?
The Anker 621 provides up to 7.5W wireless charging for compatible iPhones. This is slower than wired charging or newer 15W Qi2 wireless chargers.
Can I charge the power bank and my iPhone at the same time?
Yes, it supports pass-through charging, meaning you can charge the power bank while it is simultaneously wirelessly charging your iPhone.
Buying Guide
When looking at portable chargers like this, you're balancing capacity, charging speed, and portability. You need to consider how much extra battery life you actually need and how quickly you need it. Don't expect a tiny power bank to fully recharge your phone multiple times; they're usually for extending your day or for emergencies. Also, wireless charging is convenient but often slower and less efficient than wired charging.
5,000mAh battery_capacity
This number tells you the theoretical energy storage. For a phone, it means you'll likely get about 60-80% of your phone's battery capacity delivered as usable charge, not a full 5,000mAh, because energy is lost during conversion and wireless transfer.
Wireless Power Bank
This means you can charge your phone by simply attaching it to the power bank, without a cable. It's super convenient, like a magnetic hug for your phone, but it's typically slower and generates more heat than plugging in directly.
MagSafe-Compatible
This ensures a strong, precise magnetic alignment with your iPhone 12 or newer, so the power bank snaps into the perfect position for wireless charging every time. Without MagSafe, a wireless power bank might not stick or charge reliably.
Alternatives
If this power bank doesn't offer enough charge or speed, look for models with 10,000mAh capacity for more power, or those with Qi2 certification for faster 15W wireless charging.
