If you’ve been scrolling through the complaints about the Apple Air MagSafe Battery, you’re not alone. At $99 it’s the kind of price tag that makes you pause mid-scroll and wonder if someone’s joking. Then there’s this other option: the 5000mAh MOVE SPEED 0.3″ Ultra Slim MagSafe Portable Power Bank, for $20.99 (was $29.99).
Complaints about the Apple pack started the moment it hit shelves last week. People expected a seamless extension for the razor-thin iPhone Air, but what they got was a 3,149mAh capacity that barely nudges the phone’s runtime from 27 hours of video playback to 40. That’s a 65% boost on paper, sure, but in real life, it means one solid day of heavy use before you’re hunting for an outlet again. And at nearly $100, that feels like paying premium for a polite suggestion rather than a full solution.

When you switch to the Move Speed pack, the contrast sharpens quickly. This power bank fits 5,000mAh into a body that’s only 0.3 inches thick—thinner than a stack of three credit cards and light enough to forget it’s attached to your phone. Snap it into the rear of your iPhone Air (or any MagSafe compatible model starting with 12), and you’ll have enough electricity to fully recharge the battery at least once, with enough left over for a second partial top-up. It’s under $30 and includes a USB-C connector for self-recharge, with a normal power adapter to fully charge in about two hours.
Size is important in portable charging and the Move Speed wins hands down. Apple’s battery, designed for the iPhone Air’s slim profile, measures about 3.8 by 2.7 by 0.3 inches and weighs a feather-light 3.95 ounces—impressive on its own until you remember it’s optimized for a phone that’s already pushing the limits of thinness. The Move Speed has the same 0.3-inch depth but measures about 4.1 by 2.7 inches, so it fits comfortably in a pants pocket or purse without bulk. At 4.2 ounces it’s an extra gram but provides over 60% more juice.
The Move Speed can deliver up to 7.5 watts wirelessly (18 watts wired) which is compatible with the iPhone Air’s specs. Plug it into a 20-watt adapter via USB-C and passthrough charging allows you to charge the bank and your phone at the same time, which is faster than Apple’s configuration in most tests. Real world tests show that it can charge an iPhone 16 to 70% in 45 minutes, faster than most other competitors in the sub-$30 range.
