Perfect for long days when on the go

Slim and compact which is perfect for carrying if you’ll be out on a day trip. This is much better than having to carry a larger and heavier power bank. It doesn’t get very warm when I’m charging my iPhone 15PM via MagSafe. If I charge my iPhone by USB cord as a typical power bank but not attached by MagSafe, it does get warmer but it will also charge faster. You can leave this attached to your iPhone by MagSafe but charge using a USB cord if you hold on to the button for a few seconds. Charging this way does leave the battery almost coffee cup hot. It seems the battery gets hotter with wired charging and when attached by MagSafe, the extra warmth from the iPhone itself makes the battery hotter like a cup of coffee for comparison. Not dinging Anker for this since all power banks get warm to hot when charging. Note that all power banks can’t charge a device at the power banks’ maximum capacity since there’s some energy loss (about a third of the total capacity) when charging a device. This is noted in a few of the product images but not really detailed in the description. The compact size, portability, and MagSafe/Qi more than makes up for this since I really only need this for long days where I might not have access to a power outlet or on the go without having enough time to plug into an outlet. I don’t need to recharge my phone 100% and the Anker Nano Power Bank provides more than enough to get me through a long day. The white case has a matte finish. The sides appear to be aluminum. I avoided the black one since photos from other user reviews show a lot of finger prints and smudges. Build quality seems really solid. Magnets seem pretty strong; stronger than the MagSafe puck sold by Apple. It can rotate with enough force when pushed from the bottom corner but there is an alignment magnet. Otherwise, it attaches pretty securely with MagSafe. It’s as secure or more secure as any MagSafe accessory made by Apple. Only minor caveat is that it can be easy to accidentally press the power button if the power back is attached by MagSafe and you’re holding and using the device. This will disable MagSafe charging. If it stops charging and you know there’s power left, just press the button again. Read more

Good product. Amazon shipping sucks

The power bank does everything fine and looks high quality. It’s small and light, providing the right amount of charge that I usually need. But I have to criticize how poorly Amazon handles their shipment. I purchased this one as new, directly from Amazon. When it arrived, the package was obviously opened and the interior packaging material was also removed. I had to returned it. It’s not just a waste of people’s time, including their own staffs’, but also hurts its credibility from a customer’s perspective. Read more

Solid slim battery pack that charges well, but like others, does get hot.

***Update*** Anker contacted and gave good recommendations and expectations for slim high speed battery charging battery pack. This is a good travel in a pinch battery pack to keep level battery when traveling when slim design is a priority. It's a solid slim battery pack for the price. It's a great way to top up my iPhone Air. This charges quickly and I use it wireless if I need a quick top up, and if I need all the juice, I use my short USB-C to USB-C cable. The battery pack does get warm, if not hot when topping up my phone from very low phone battery. I've gotten the message that the phone charging is paused due to heat, but I've gotten this with every wireless battery pack so far except for an Apple battery pack. For the price and size, and with my proper expectations, works great. The magnetic strength is as solid as my Belkin and Baesus battery packs. Works well on my iPhone Air, my spouses 14 Pro, and my 13 mini Read more

Perfect Portable Charger for My iPhone 17 Pro Max

⭐️⭐️⭐️⭐️☆ I fell in love with the color the moment I opened the box—it looks even better in person. I brought it with me on a trip to San Francisco, and its portable size and lightweight feel made it easy to carry in my pocket and bag. Definitely 5 stars for size and weight. I tested the power on my iPhone 17 Pro Max, starting at 18%, and it charged up to 80% in one session. It did get slightly warm while charging, but nothing extreme compared to other Qi magnetic power banks I’ve owned. The compatibility was perfect—just snap it on and it starts charging instantly with no alignment issues. ✅ Pros • Beautiful color and premium look • Very portable and lightweight—great for travel • Strong magnetic hold on the iPhone 17 Pro Max • Charges smoothly from 18% to 80% • Doesn’t overheat like some other power banks • Good balance of size, power, and design ⚠️ Cons • Doesn’t fully charge the iPhone 17 Pro Max to 100% in one cycle • Gets warm during charging (not hot, but noticeable) • Would be nice if it had a battery percentage display • Works best with MagSafe cases—may not stick as well with thicker cases Overall, it’s a great compact power bank with solid performance, especially if you want something stylish, travel-friendly, and reliable for quick boosts on the Read more

Good buy 👌

Nice and slim, just like the description says. No extra cords to carry so ladies, this should fit into whatever handbag you’re toting or your jacket. Guys this should fit like a second wallet. I have an iPhone 17 and it fits perfectly. Secure too. I have other Anker products and I’m pleased with everything so far. They all fit my Apple products perfectly. Even my Apple air pod pros 3 case fits on it. It comes with everything you need. You will need to charge it out of the box first as it doesn’t come with a full charge. Read more
