One of many first guides I ever labored on for Engadget was about energy banks. Within the years since, I’ve examined greater than 50 transportable batteries to maintain our prime picks as up-to-date as potential. Now that the iPhone 17 is on the horizon — and rumored to be the thinnest ever — we wished to commit some house to MagSafe battery packs specifically.
I gathered up a brand new crop of batteries to check and in contrast the outcomes with our current information to choose the very best MagSafe-compatible battery on the market. As we be taught extra concerning the new iPhone’s battery specs and get our fingers on banks enabled with the brand new Qi2 25W charging customary, I’ll proceed to replace this information. For now, our prime choose is Anker’s Qi2-enabled MagGo 10K energy financial institution. It has a giant capability, quick charging instances and helpful additional options like a stand and show. However there are additionally choices right here for minimalists and the budget-conscious, too.
The most effective MagSafe energy banks for 2025
What to contemplate earlier than shopping for a MagSafe energy financial institution
Select the fitting capability. Most transportable MagSafe chargers have both a 5,000 milliamp hour (mAh) or 10,000mAh capability. Clearly, the bigger capability batteries are bodily larger, however because of an iPhone’s magnetic attachment factors, you may nonetheless use the telephone comfortably because it costs. For those who’re apprehensive about total bulk, you could favor the slimness of a 5,000mAh battery.
Simply word {that a} 5K battery pack gained’t ship its total capability to your telephone on account of vitality loss from voltage conversion and warmth dissipation. Over time, I’ve measured round a 60-percent supply fee for wi-fi banks. For instance, which means an iPhone 16 with its 3,561mAh battery will get about 85 to 90 share factors from a 5K battery. A 10K financial institution will cost that very same telephone totally as soon as, with sufficient for a 50- to 60-percent enhance subsequent time.
Perceive MagSafe versus Qi2. All iPhones mannequin 12 and later have MagSafe expertise, which depend on embedded magnets to align the telephone with a wi-fi charger and might assist charging speeds of as much as 15 watts. The MagSafe title is owned by Apple — third-party chargers can’t freely use the time period and as a substitute name their equipment “magnetic,” or apply a branded title like Anker’s MagGo or UGreen’s MagFlow. Make sure to verify the product particulars earlier than shopping for: something that works with Apple’s expertise shall be listed as MagSafe-compatible.
Qi2 is a regular from the Wi-fi Energy Consortium (of which Apple is a member) and has the identical stipulations as MagSafe (15W charging and magnetic alignment). Any firm can submit their tech for this certification. iPhones 13 and later are Qi2 appropriate.
A brand new customary is coming this fall; it’s known as Qi2 25W and bumps wi-fi charging speeds as much as 25W. The WPC says an authorized smartphone utilizing an authorized charger can wirelessly go from lifeless to half full in about half-hour. These gadgets will begin hitting cabinets within the fall of 2025 and it’s extremely doubtless that the brand new iPhone 17 will assist it. Plus, it’s doubtless that iPhone 16 fashions will retroactively achieve the certification since these telephones already assist 25W speeds when utilizing Apple’s official MagSafe Charger puck.
Bear in mind journey restrictions. You might have seen information reviews of flights being grounded as a result of an influence financial institution caught hearth within the cabin. Presently, the TSA permits them in your carry-on baggage so long as they’re rated at 100 watt-hours or decrease (about 27,000mAh for lithium ion batteries).
However some airways have enacted additional restrictions. Southwest, for instance, requires you to maintain energy banks out of the bag and visual whereas charging. Even when your airline doesn’t make such calls for, retaining an influence brick out within the open whereas it’s in use is a good suggestion — it’ll hold it cooler and also you’ll be extra more likely to discover if it begins to overheat. Most, if not all, MagSafe battery packs are available at underneath the 100-watt-hour restrict, so touring must be simple with one.
Think about the additional options. Chances are you’ll not want them, however the little additional perks of a MagSafe energy financial institution can turn out to be useful. Some have stands so you may watch your telephone whereas it refills. Some have LED shows that let you know how a lot cost is left, which generally is a little extra exact than the lighted pips different banks use. Some even have straps to make the financial institution simpler to hold round or fish out of your bag.
