---|---|---|
Charge Through Magnetic CasesCharge iPhone 13 and 12 case-free, or through a compatible magnetic case with zero interference. Not compatible with non-magnetic cases. |
A Pocketful of PowerWith a 5,000mAh cell capacity, Anker 521 Magnetic Battery (PowerCore 5K) provides nearly a full extra charge for your iPhone, allowing 17 additional hours of video playtime and extended productivity. |
USB-C Charging and RechargingUse the multi-directional USB-C port and included cable to recharge Anker 521 Magnetic Battery (PowerCore 5K) or provide a wired charge to other devices. |
1.Will Anker 521 Magnetic Battery Charge iPhone 11?
Yes, although it will take a long time to charge, so we do not recommend using the product this way.
2.Will PowerCore Magnetic 5K Wireless work with phone cases?
Magnetic 5K Wireless charges through phone cases that are no thicker than 5 mm. However, since ordinary mobile phone cases do not have magnets, the magnetic attraction will be very weak. We recommend using Apple and Anker official mobile phone cases with magnets.
3. Is the battery safe to use when it gets warm/hot?
This is a normal phenomenon as overheating occurs when using magnetic charging—a process of converting electrical energy into electromagnetic waves that could generate heat.
4.Will PowerCore Magnetic 5K wirelessly charge an iPhone 12 while plugged in?
Yes, it will charge the phone first, then recharge itself. Both the iPhone 12 and the battery can be fully charged in about 4.5 hours. We recommend using a charger with 5V/2A output or above.

Anker's battery has a more than strong enough magnet that keeps itself locked into place, which would be a huge issue if it didn't. I have an iPhone 13 Mini, and this battery charged my phone from roughly 35%-100% and still had a bit of battery left.
The thing about all MagSafe batteries, though, is extremely low charging speeds. Anker's battery suffers from this as well, I believe topping out at 5 watts. This is also an issue with Apple's version as well, though. I think eventually the manufacturers will figure out how to increase both charging speed and capacity in the future, but in the meantime this is one downside for me as you'll have to keep the battery attached to your phone for hours if you're trying to charge from less than 50% to full.
Something else I like about the battery is how well it fits with my iPhone 13 Mini. It's aligned perfectly as if it were meant for the Mini. This makes the previous issue of charging speeds less of an issue, because using your phone with the battery attached doesn't feel overly cumbersome, in my opinion.
Another nice feature with Anker's MagSafe battery (I believe Apple's version does this as well) is that you can plug the battery into the wall to keep it charged, then place your phone on top of it and use it as a charging pad. I believe you may even get slightly higher charging speeds with this method as well.
If you're trying to decide over this battery or Apple's version, here's an overview:
Get the Anker version if:
- You don't care about software integration
- You prefer a larger capacity
- You don't want to pay the "Apple tax"
Get Apple's version if:
- You do appreciate the software integration
- You only plan to use the battery to top off your phone's battery in a pinch
- You like the all-white design and Apple's simplistic branding
The only mild annoyance I have right now is that I have to press the power button to start the charging. I have forgotten to press the button on occasion and wonder why my phone is not charging. The charging rate doesn’t appear to be the fastest thing. I don’t know if it would be faster without my MagSafe case.

The charging speed is slow; I would look at this product as something that will maintain the phone while connected and not something that will quickly charge the phone.
I like the size, and using my IPhone 12 Pro while the battery is connected is still comfortable.
The magnetic strength with MagSafe cases have been excellent and I am confident it won’t fall off with normal use

La recarga es rápida, obvio no tanto como la recarga por cable y cargador.
Se puede usar sin problema para carga alambrica como inalámbrica, probado en iPhone 13 y audífonos pixel (ambas opciones de carga) y Motorola moto g (solo alambrica), de hecho este teléfono la detecta como turbo power.
UPDATE: Anker customer service contacted me to follow up on my experience. They were prompt, courteous, and knowledgeable. They stand behind their product and are replacing the defective device. Great customer service!
