One of the first guides I ever worked on for Engadget was about power banks. In the years since, I’ve tested more than 50 portable batteries to keep our top picks as up-to-date as possible. Now that the iPhone 17 is on the horizon — and rumored to be the thinnest ever — we wanted to devote some space to MagSafe battery packs in particular.
I gathered up a new crop of batteries to test and compared the results with our existing data to pick the best MagSafe-compatible battery out there. As we learn more about the new iPhone’s battery specs and get our hands on banks enabled with the new Qi2 25W charging standard, I’ll continue to update this guide. For now, our top pick is Anker’s Qi2-enabled MagGo 10K power bank. It has a big capacity, fast charging times and handy extra features like a stand and display. But there are also options here for minimalists and the budget-conscious, too.
The best MagSafe power banks for 2025
Amy Skorheim for Engadget Best MagSafe power bank overall Anker MagGo Qi2 Power Bank Specs: 10,000mAh capacity, Qi2 certified, display, stand, USB-C port Who is this for? The person who never remembers to charge their phone overnight. Anker’s MagGo power bank was one of the first Qi2-certified products to come to market — and it’s still one of the most well-rounded MagSafe banks you can get. It charged an iPhone 15 from 5 percent to 60 percent in a little over 45 minutes. It took under two and a half hours to get the phone from near-dead to full, and it had enough power left over for an additional 70-percent refill. A small display tells you just how much charge remains (and how long until it’s full when you’re recharging the battery). The kickstand is sturdy so you can use the phone hands-free in portrait mode, or you can twist the phone to watch something in landscape orientation. Like many Anker products we’ve tried, it has a sturdy build and a clean aesthetic. Plus, it comes in purple, blue and green in addition to the standard (and comparatively boring) black and white. Though it’s on the pricier end of the battery pack spectrum at $90, it’s often on sale for $70 and has sold for as little as $50 on Amazon. Pros Delivers a fast charge
Enough juice for 1.7 iPhone 15 charges
Sturdy stand lets you watch while charging Cons Pricey when not on sale $90 at Amazon
Amy Skorheim for Engadget Best slim MagSafe power bank Anker Nano 5K MagGo Slim power bank Specs: 5,000mAh capacity, Qi2 certified, under 5 oz, 0.34-inches thick, USB-C port Who is this for? The minimalist; the person who wants their power bank to blend in. iPhones are sleek and slim — if you want the same from your portable charger, Anker’s new Nano 5K MagGo Slim is a good pick. It’s one of the thinnest chargers I’ve ever tested and has a nice, smooth matte texture. Since it’s thinner and a little wider than many battery packs, it’s ideally proportioned for a standard iPhone, stretching edge-to-edge on the back and sitting just below the camera. That makes it easy to grip your phone and use it as it recharges. There’s no stand, strap, screen or any other extras, but that’s the point with a minimalist accessory like this. It took an iPhone 15 from 5 percent to 90 percent in about two and a half hours. Like all power banks, it slowed down significantly after the pack was half drained, so it’s worth noting that it charged the phone to 40 percent in less than an hour. Pros Slim enough to blend in
Minimalist design
Premium build Cons No stand, screen or strap $55 at Amazon
