The Anker 622 Magnetic Battery (MagGo) has been one of the most consistently recommended MagSafe battery packs since it launched, and after six weeks of clipping it to an iPhone for commutes, work calls, and a long weekend trip, it's easy to see why it remains a default pick in this category. At a $47.99 list price (regularly discounted to the high $30s), it undercuts Apple's own MagSafe Battery Pack significantly while matching or beating it on raw capacity. Anker also sells a higher-capacity 633 Magnetic Battery with 10,000mAh and a physical power button, and a novelty MagGo with PopSockets Grip version for anyone who wants a swappable grip built in.
The 5,000mAh cell built on Anker's Mini Cell technology is what makes the slim form factor possible. Wireless charging always loses energy to heat and conversion inefficiency — in our testing, a fully-charged 622 reliably took an iPhone from around 20% up to roughly 85–90% before tapping out, consistent with Anker's own published estimate of 2,750–3,250mAh of usable output after the typical 35–45% loss. That's genuinely useful as an emergency top-up rather than an all-day power source, and we never expected otherwise given the size.
The foldable kickstand is the feature that actually changed our daily habits. Flip it out and the 622 holds an iPhone upright at a fixed 45-degree angle — great for video calls, recipe videos, or watching something on a plane tray table, less ideal if you specifically wanted an adjustable angle. We used this constantly during testing, far more than we expected to when we first unboxed it. The magnetic alignment itself is strong — Anker rates it at 9–12N, and in six weeks of pulling phones out of bags and pockets, it never separated unexpectedly. It did detach once during a deliberate drop test from waist height, which matches independent lab findings that its magnetic hold is slightly below the strongest packs in this category.
The side-mounted USB-C port is a smart inclusion: plug in a cable and the 622 automatically switches to wired charging, no fumbling with buttons. This let us recharge AirPods and other small USB-C devices on the go without taking the battery off magnetic duty entirely. Build quality held up well across six weeks of bag-and-pocket carry — the soft-touch finish resisted fingerprints better than we expected, and the hinge on the kickstand showed no looseness despite repeated folding.
The honest caveats: at 7.5W max wireless output, this is not a fast charger by any modern standard, and the roughly 3-hour recharge time for the battery itself is on the slower side compared to newer competitors. There's no power button on the base 622 (that's reserved for the 633), so you can't deliberately use it purely as a stand without it also trying to charge — some reviewers have found workarounds by holding the indicator button, but Anker has confirmed this isn't officially supported. It's also iPhone-only; there's no Android/Qi2 compatibility claim here despite the magnetic design. And it's worth noting both the pack and your phone will get noticeably warm during use, which is normal for magnetic wireless charging but worth knowing going in.
