One of our favorite magnetic power banks is on sale for 42 percent off right now. The Anker 622 Magnetic Battery is down 42 percent to $28, which is almost as low as we've ever seen it. This steep discount is also available at Anker's online store with a coupon code that the company provides. This 5,000mAh MagSafe-compatible charger with a foldable stand is a slim and portable battery that can keep your devices going on long days away from a charger. Anker says the 622 Magnetic Battery can recharge a dead iPhone 16 or 16 Pro to just over 80 percent, and an iPhone 16 Pro Max to just over 60 percent. In our hands-on review of the portable charger, we liked the magnetic stand that folds out into a 30-degree angle. Users can rotate their phone to either portrait mode or landscape mode while charging. The Anker 622 is an older charger, so it outputs a maximum of 7.5W when charging wirelessly. If you need to refill your battery faster than that, you might want to pick up one of the newer Qi2 power banks. Though a Qi2 power bank will, of course, cost more, some of our favorites are having great sales right now.
