Anker Magnetic Portable Charger, 5,000mAh Wireless Portable Charger with USB-C Cable, Battery Pack Only Compatible with iPhone 15/15 Plus/15 Pro/15 Pro Max, iPhone 14/13/12 Series and more

I ordered this product because I have been exceptionally happy with Anker’s other products and support. The battery itself works exactly as expected. Like others have noted, it takes much longer to charge up the battery than expected. That’s not a problem for me – when traveling I will just charge it overnight.

I was not expecting a power button. Mine does not turn on automatically when attached to the phone, and I have forgotten to turn it on. Not a problem…it charges the phone fast enough that it just isn’t a problem to turn on the battery when I remember and go from there.

Note: Photos are taken with the chargers on an iPhone 15 Pro with a Mous Limitless 5.0 case.

Size:

The 621 is thinner but longer than the 321 which, as the product description states, means that the 621 extends (slightly) past the bottom of a non-Max iPhone Pro (tested on a 13 Pro and a 15 Pro). However, for both the 13 Pro and the 15 Pro, once the case was on (Mous Limitless 4.0 on the 13 Pro, Mous Limitless 5.0 on the 15 Pro) the 621 was basically even with the bottom of the case. It may extend past the bottom of a lower-profile case. The 321 does not extend past the bottom of the case but is a bit thicker.

The 321 is a couple of grams lighter than the 621.

Appearance:

The 321 has a smoother, glossy-ish finish but seems to show more scratches when tossed in a backpack pocket with keys. The 621 is a more matte finish and not as slick, which may be a benefit from the standpoint of grip but shows fingerprints more easily. Both chargers are about the same when you put the phone in/take it out of your pocket (occasionally comes loose, depending on how tight your pockets are, but not often). Despite the more rounded edges of the 321 the 621 seems a bit easier to put in a pocket without catching it.
The 321 has a round “power” button with inset 4-light charge level indicator on the face of the charger case. The 621 has separate “power” and 4-light indicators on the bottom (either side of the USB-C charging port).

Notes:

Both have the same nominal capacity and seem to charge at about the same rate. Both allow you to charge a non-MagSafe compatible device (or if you have a non-MagSafe case) using a USB-C cable (provided the charge requirements are similar enough to the iPhone). When attaching to a MagSafe phone/case both start charging the phone automatically, but if using a cable you have to click the “power” button after plugging the charger into the device to activate charging.

I paid about $30 for the 621 ($35 less a $5 promotional coupon) and $25 for the 321. Overall I prefer the 621 as the finish seems higher quality and I prefer the thinner box. However, a $5 price difference makes it about a wash (I would still probably get the 621), but at $10 less the 321 is the winner.

Put these to the test over the course of a few months. Purchased Apple’s version of this for full retail price ($99.99). Figured for the price, i bet it’d do great things for my battery life… Turns out it never gets close to fully charging my phone, it gets me up to only about 30% of increased charge (on a good day). Noticed only about 20% on an average day’s use. Additionally, the Apple one does not come packaged with a charger for the device you’re buying. It is packaged by itself and you’re expected to already have a charger or buy a new one. The product itself dies so fast i feel like i am charging it more than i do any of my apple tech, even my airpods — which really illustrates the irony here. Apple somehow came to the decision of selling us a rechargeable battery with no charging chord included. One thing i’ll say about the Apple Magsafe is that it survived a wash cycle when i accidentally threw it in with my bed sheets, so in all honesty, that was pretty impressive. Now moving onto Anker… first of all, anker comes with a charger! And detailed user manual. More than half the price less, Anker comes with advantages outweighing the Apple name by dividends. Anker’s customizable marketing is insane — browsing through their portable chargers, you’ll see that they have different ones at different prices, specifics vary enough for just about everyone. after choosing the model best for you, select your personal favorite from a plethora of color options! So you get a charger + your favorite color in your purchase…that’s a great start. Now let’s get into the experience. This thing charges my phone nearly 50% at least increased percentage FAST and stays on for hours at a time. I’ve gotten up to 80% charge so many times. Has a dotted illuminated sequence feature along the bottom edge that will convey the status of its charge, as well as remain lit when you power the device on, and diminish when turned off/dead. This is convenient to tell if you’ve left your device on but meant to turn it off, or have it off and need to power it on. The power is triggered by a small side button that requires direct pressure from your hand. It is dense enough to prevent any accidental powering on or off as you hold or carry the device, there are no annoying mistakes made there as one would preemptively assume, which is great to have that intentional detail actually very well serve its purpose. This model is slim enough to hug my phone without unnecessary bulk. Much like any other magsafe devices on the market, yours will increase in temperature and feel warm for the duration of your charge. This is not something you can escape due to any compact battery using the limited space it has to conduct a power charge to another device, so accept the science happening there. Size is longer than the Apple, slightly wider in width by a micro amount, and noticeably taller in height. These size differences were not inconvenient due to how slim the device itself is, and how it sits on the device is comparable to the Apple. Weight is not heavy, but you can feel the difference when charging your phone, won’t lie about it looking lighter than it is. In conclusion, spending $100 on an Apple product seems to be just that — it’s $100 only BECAUSE it’s an apple product, if you want the logo then pay the price, and get a wimpy charge. i would suggest purchasing 2 magsafes to have with you if you’re going the Apple route. it’s just not enough for the reasons targeted customers would need this and benefit from it. To any busy, on the go/working/social human being on the market for a product they can depend on to power through the day in order to make ends meet; remain available to others; or ensure their safety. These things really do impact your day and for that you deserve something that will make all the difference. As i come to an end of argument here, I will conclude with the reason i wrote this very long review in comparison of said two products. The answer is because i was searching endlessly before I found nothing detailed enough to make or break my decision or many questions, so that’s why i just bought them both over time. Hopefully this helps someone genuinely curious about this debacle like i was, and anyone researching before spending their hard earned money. Thanks again to anyone for reading. Just wanted to give the review I would have wanted to read. This isn’t sponsored by the way, i am currently using my Anker charger whilst writing this long awaited review on my flight right now. LOL. We’re currently sitting at 88% and still charging!! Cheers.

I bought 2 of these for my wife and I since we were tired of bringing massive chargers around. I just returned from deployment and hit many ports. I have several Anker chargers from 10K to 20K mAh. These are cumbersome carrying around in a pocket, but this form factor is perfect and attaches to the phone with no issue.

The charging speed is just ok. It will charge when you are out and about not becoming uncomfortable in your pocket. Again, best form factor. 1 of mine will stop charging consistently when connected. I have used it on multiple phones with the same result. It’ll charge for the first 30 seconds and then cut off even though it’s fully charged. My other charger works as advertised. They do get hot in your pocket but it’s not uncomfortable or really an issue, just something to note. Will send the first charger back and get a new one and I’m sure it’ll be fine.

It’s a great battery so far it’s a nice replacement from my mophie one but it has some negatives from my mophie one but it has more positives

Pros:
-it’s very slim
-it charges 5w-7.5w wirelessly
-Very strong magnets
-very strong usbc port
-Doesn’t interact with the camera bump on my 13 mini
-really nice materials and build quality
-it has pass through charging (when plugged in it can charge itself and my phone at the same time
-it has a rubber type material so on the non matte back iPhones it will grip on more making it harder to slide off

Cons:
-it charges very slow im using a 45w ac adapter and it seems to be charging at 20w my mophie one can charge at 45w for 2 hour charging time the anker one has been on the charger for 2 hours and just got to the 3rd led
-it gets warm when charging my mini but if you have a bigger phone your phone won’t get as hot when charging

Misc:
-it turns on automatic my when i put it on the back of my phone but before that I can turn it on with the button and hold the button so it won’t turn on until I want to use it
-the button is very clicks and solid
-the leds are bright enough but hard to see outdoors
-it doesn’t have the official MagSafe charging animation
