I was iffy about spending $40 for a mere battery pack. I was on the edge and it was hard to fathom spending that much on some little power bank. But I didn’t cheap out, and I went full send. This was literally my best purchase ever for my iPhone 16. I’m completely appalled at how strong MagSafe really is (I’m a new Apple user, and didn’t think much of MagSafe prior), but now I see why people walk around with those weird MagSafe phone cases. The color is a very nice matte black, and has a smooth feel. When I was an android user, I thought everyone was an NPC for walking around with their little MagSafe cases. I didn’t know what it was and never understood it until now. This was the best $40 I’ve ever spent. On top of that, it’s compatible with AirPods and Apple Watches. It charges fast. Like I said, I didn’t get to play around with it yet, but it’s very promising. I’ll update when I do. And when I say the magnet is strong, I mean STRONG. I can literally hold the Anker while it’s attached to my phone, and allow my phone to dangle. You literally can’t make it fall off on accident. And my favorite part; portability and convenience. You have to turn on the Anker with the power button on the bottom, and that means that it won’t charge your phone until you turn it on. This also means that you can have it attached to your phone without worrying about it charging your phone and wasting battery. It’s literally INSANE. It feels no different in my hand when the Anker is attached. Honestly, this is the best $40 you can spend on your iPhone.

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.

Bought for Easter basket stuffer. My son loves that he can throw it in his backpack at school so if he needs to charge it and it just magnets to the back of his iPhone. Works on my android too, just dont stick as well to an android as it does the iPhone. Long lasting battery and all the kids share it. Definitely worth the money for traveling or school. Very happy and would buy a 2nd one just to have around the house.

Does not charge an iPhone completely and it doesn’t have to much power so it would probably only give you only one half charge of your liking for a portable charger that can last 1-2 days this is not it this is only for a quick charge then you have to charge the pack again. I have it 4 stars cause there is nothing wrong with it just not powerful

Che prodotto eccezionale! Il Power Bank si merita ampiamente 5 stelle. Sono rimasto davvero impressionato da questo caricatore. La capacità di 5000 mAh è perfetta per dare una carica al mio iPhone quando sono in giro, e il fatto che sia magnetico è una svolta. Si attacca al telefono in un attimo, senza bisogno di cavi aggrovigliati o preoccupazioni che si stacchi. La presa è super solida, anche quando lo tengo in mano o lo metto in tasca. Il cavo USB-C integrato è un dettaglio geniale, così ho tutto il necessario in un unico pacchetto compatto. Anker si conferma una garanzia per la qualità costruttiva e l'affidabilità. Se avete un iPhone compatibile e cercate un power bank comodo, efficiente e stiloso, non cercate oltre: questo è il prodotto che fa per voi!

I already have the Anker Magsafe Go UltraFast Powerbank that's available here (the one with the display on the side). The problem with that is that it's the same weight as a brick, and takes up twice the amount of space in my lunch bag (I use one of those Husky ones, the ones you see construction workers use), so that lead me to look for something a bit slimmer. I do have the Apple MagSafe power bank that I got when it first came out, but with the purchase of my 16 Pro Max, using that was out of the question since I wanted to shed myself of using anything that's Lightning related (since all my devices are now USB-C. It does however remain on standby in case it needs to be used, and all I carry are USB plug ins and cords). So far with the Anker 621, it's living up to my expectations. They say you can only use this on an iPhone 12, 13, 14 or 15 series, but I haven't had an issue using it on a 16 Pro Max. With this, there is a power button on the bottom to turn off the charger when the iPhone throws up temperature warnings, which is absent on the UltraFast Powerbank (you have to remove it, let it cool and then put it back on, with the 621, you can just hold the button on the bottom to turn it off, then when it's cool, turn it back on again). Since it only delivers 7.5w of charging via Magsafe (vs 15w with the UltraFast), unless you're using your phone, this will provide a boost but I haven't found out what kind of one since at the time I wrote this, I am on vacation from work. I will update this accordingly after it gets put through it's paces.

Good MagSafe charger, comfortable during charging and holding, also its easy to travel with only Type-C cable and charge the phone overnight using MagSafe, however it gets a bit too hot that could be annoying in a warm weathers if you have phone in a pocket
