I forget how much I rely on my mobile phone -- until that battery indicator turns red and the phone shuts off. Whether I'm just kicking around town or stuck somewhere miles away from a power outlet, I don't want to be left literally powerless. My favorite magnetic battery charger for iPhone hits the sweet spot of price, power and portability, and it's one of the more popular items on sale now during Amazon's October Prime Days event, with up to a 55% discount.
The Anker 622 MagGo is a small slab of battery with a few features that make it an ideal on-the-go accessory. Amazon often drops prices on specific colors, so be sure to click through each model to find the best deal.

The Anker 622 MagGo is small enough to go anywhere a charge is needed.
Here's why I've stuck with this little charger for so long
Have you seen people walk around with a loop of cable hanging from their pocket to their phone? I've been there and hooked that loop on too many chairs and table corners. Never again. The ring of magnets in the Anker 622 MagGo aligns with the MagSafe magnets in every iPhone since the iPhone 12, latching securely and charging without wires.
It's also compact -- a little backpack feeding power to the phone while you're holding it or have it stashed in a pocket, even a jeans pocket if your fit isn't too tight.
Those features alone would have convinced me, but the Anker 622 also includes a fold-out back flap that props up my iPhone and can also hold the phone in its wide orientation for StandBy mode. With a power adapter such as the Anker Nano Pro (not included) and a charging cable, I've taught long classes with the phone angled to help me keep track of the time without checking my watch.

MagSafe-compatible charging
I've owned several battery chargers, and each one has some sort of compromise. They're bulky. They require a cable. They charge wirelessly but don't include a magnet to keep the phone in place, so it's hard to maintain that connection. There's always something.
The Anker 622 is half an inch thick and snaps onto the back of my iPhone using the MagSafe-aligned magnets. I don't have to turn it on to start charging -- power flows as soon as the connection is made.
Now, this isn't the highest-capacity (5,000 mAh) or fastest portable charger. That's fine. What I usually need is a way to eke out a few more hours of battery life on my iPhone. I can typically get a full top-off of my iPhone 15 Pro.
The Anker 622 MagGo is smaller than an iPhone 15 Pro.
Making a stand
The other appealing feature of the Anker 622 MagGo for me is its built-in stand. Honestly, it doesn't look like it should work well: It's a fabric-covered set of plastic pieces that lie flush against the case, folds in two places and attaches to the back of the unit with a magnetic strip when extended. Yet I've had no problems with the stability of my iPhone 15 Pro or even the larger iPhone 15 Pro Max size.
The stand on the Anker 622 MagGo slides down and adheres with a magnetic strip.
This also lets me use StandBy mode by turning the iPhone to landscape orientation (the magnets are strong enough to hold the phone in place) when it's on a table or desk.
Flip the iPhone horizontally to take advantage of StandBy mode while charging.
Smart port placement matters
The charger gets its juice from a single USB-C port, which is positioned on the edge of the case, not the bottom. That means you can replenish it while the stand is open -- many chargers' ports are stuck on the bottom.
Having the USB-C port on the side keeps it accessible even when in its stand configuration.
That USB-C port also acts as a charger for other devices when you plug in a cable, such as when your Apple Watch needs a boost.

How the Anker 622 MagGo compares to similar power banks
Before getting the Anker 622 MagGo, I carried an Anker PowerCore III 10K Wireless, which doubles the battery capacity, includes a USB-A port and charges wirelessly but without magnets to hold the phone in place. That meant if I didn't use a cable, the phone and charger needed to be stable and level; too often I'd find the iPhone slid off its wireless perch and not charged. It's also larger and heavier. I still use it, but it's the power bank that goes into my carry-on suitcase as a backup charger.
The Anker 622 MagGo is much smaller and lighter than my old reliable Anker PowerCore III 10K Wireless, which is now a solid backup.
Since I've owned this Anker 622 MagGo, the company has released a few updated models. The Anker 633 packs 10,000 mAh into a slightly thicker brick, includes a USB-A port in addition to USB-C and has a metal kickstand for resting the phone upright. Right now, it's on sale for Prime Day for $40, or 50% off.
For $62 for Prime Day you can get the chunkier Anker MagGo Power Bank that delivers 10,000 mAh and follows the same idea of compact magnetic charging and a convenient kickstand. Its main appeals are faster 15-watt magnetic charging and Qi2 compatibility, plus a small display on the side that reports the battery capacity and an estimate of the remaining battery in hours.
