Reviewed in the United States on March 28, 2022

I have used Anker products for a few years now and I have always been impressed with them. This unit is no different I occasionally drive a company truck for work which doesn’t have usb-c charging and that is one of the main reasons why I chose to get this charger. This charger is small and compact which is great because it can fit in any pocket and I love the fact that if I don’t have a charging wire I can just slap it on the back of my phone which is so convenient! (However make sure you have a MagSafe compatible case if you are using an iPhone) The only downside is because of its small battery it will not charge your phone to 100% (via the MagSafe charging feature I have yet to charge my phone via lighting cable) if your phones battery is lower than 25% but it will give you enough charge to get through your day! All in all I’m very pleased with this charger!

I just recently got an iPhone with MagSafe, and I’ve gotta say this battery and accessories like it are a game changer. I can get about an 80% charge for an iPhone 13 pro from empty. It’s so easy and great to have around, far better than the old mophie-style battery packs. I wish the capacity was a little larger, but it’s pretty good. I got it on sale, but even at full price this or the newer version would be a far better deal than the apple version. My only complaint is that the magnets seem a bit underpowered, because in a pants pocket the battery often becomes detached. Overall not a dealbreaker, definitely great if you can find it on sale!!

Great alternative to Apple's MagSafe Battery if you don't care about software integration

Reviewed in the United States on October 17, 2021

This battery is priced much more fairly and has a higher capacity than Apple's own MagSafe Battery. Of course, you won't get the software integration of Apple's battery with Anker, but is the software features worth an extra $50-60, while losing out on battery capacity? That's up to you.

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

Great to Have Away From Home

This magnetic battery pack is great for traveling; grocery store trips, going to class, airports, etc. The magnets are strong and the grip is good (passes the scientific shake test). The battery pack will bulk up the phone quite a bit; I don’t really notice it while using the phone with the charger connected, but fitting this into pockets may be an issue. You can just throw the combo in a bag until you need to use it. It doesn’t charge as fast as a normal magsafe charger or lighting charger, but it’s enough to top off or sustain your phone’s battery when access to outlets is limited or when you’re on the go.

Excellent battery

I love this little battery. When I am home, I walk around with my phone and eventually my phone needs to be plugged in. This allows me to charge the battery while I am moving from place to place. Functionally it stays on great, except when I put it in my pocket. It does what it is supposed to do.
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.

Excellent For Magsafe Phones

Great battery option for iPhone 12 variations at a very good value. I tend to be someone who gets a battery case for my iPhone. I currently have an iPhone 12 Pro Max. Since Apple hasn't released a battery case yet for my phone, I decided to give this one a try. So far I am quite pleased with it. I like the fact that it charges via usb-c. It also has a very good magnetic hold to the back of my phone. As soon as I understood that the wireless charger had to be activated (either by plugging it in or by hitting the power button), it has worked great. For the most part, I have simply left it attached to my phone since I got it. It supports pass-through charging, so I can just keep it attached and plug in the battery pack. I was happy to find that I could still fit my phone with the battery attached into the same pocket that I normally use for my phone, though your pockets may vary. While a battery case can be sleeker, I do like the convenience of being able to detach this easily whenever I want to. I think the only thing that could improve this is if it was an official Magsafe device and could charge at full Magsafe speed. That said, this has not been an issue at all for me so far, and I have to imagine that would cause a price increase. So far, I am quite pleased with this battery.

Heats up quickly, but can't beat its convenience

Reviewed in the United States on November 15, 2023

I'm a big fan of Anker's products, so I gave this one a try since it comes in at about 1/3 the price of Apple's magsafe battery.

What I like:
- USB-C input and output
- Small size
- Feels sturdy
- Reliable

I love that this small power bank can charge my phone without a cable and it makes it super convenient to take on the go. I also really like that it can charge other devices via the USB-C port used to recharge it.

What I don't like:
- Gets hot quickly
- Charges magsafe devices slowly (5W)

The main downside of this battery bank is that it charges your phone much more slowly (5W) than the Apple version (15W). It also heats up noticeably, but not to the point where it is painful or seems dangerous. The only other thing that I've encountered is that it doesn't start charging your phone automatically after it snaps on. Once you stick it to your phone you also have to press the button on the bottom to start charging.

Overall, I'm happy with this product, especially for such a discount over the Apple version. It is great for backup juice on the go, but I wouldn't rely on it daily as the slow charge speed and heat might get annoying.

I have so many charging banks that it might be a slight obsession. Standard bricks, wireless, ones with fold out prongs, solar, credit card size, you name it, I have one. This is the first one that scratched all the itches and was something I didn't know I needed until Apple added the mag option. The fact this battery just attaches to the phone and wirelessly charges it so I don't have to hold it separately or balance or use a cable is awesome. It just works and works well. The magnets hold firm when generally holding it with the phone but it will slip if too much pressure is set. The capacity is ideal to get you that extra few hours of use when needed. On it's own, it's not very large which is great. Maybe a little thicker than I would like, but overall I'm still able to hold the phone with the charger attached without problem (I don't have the Pro). It definitely adds weight to the phone when attached, but not as much as you might think. This is going to be my portable charger going forward.

Compatible with S23 Ultra NOT PIxel 6

S23 ULTRA:
I have a Spigen Case on my phone in which the magnet is almost TOO powerful, especially on my popwallet. This charger is much weaker in attraction. However, it charges the phone nonetheless I am just a bit worried over time. I like the design and feel of the device. Next, I purchased this since it is significantly lighter than the 10,000mah option. When traveling, I can usually recharge my items at the end of the day and only need one for all day touring (lots of photos, lots of bluetooth shutter connectivity etc). The charge is not very fast but that's the nature of wireless charging perhaps. I chose this option since it is cheaper than other leading magsafe chargers but now I'm not sure if opting for a more expensive option would have given me a lightweight and quick charging option with more power.

I have seen many Google Pixel 6 Pro users use a magnetic case with a magsafe charger but no one has tried this particular charger before. I am sad to say this is not compatible with the phone. The magnet works but does not charge. FYI it does wirelessly charge with stands and has charge sharing capabilities.

I would have tried other brands which could accommodate both phones, lightweight, quick charging, and holds more power.
