Mophie’s new Snap+ Juice Pack Mini is a well-priced and well-designed compact portable battery that plays nicely with MagSafe, but there are some caveats that potential buyers should be aware of before purchasing.
It would be easy to conclude that the new Snap+ Juice Pack Mini is MagSafe certified. After all, the company’s own marketing repeatedly references Apple’s MagSafe, noting that the battery pack is “compatible with MagSafe for iPhone 12 models.”
However, that’s not actually the case. Mophie’s new battery pack simply offers Qi wireless charging, holding the battery in place on your iPhone 12 with a series of magnets that align with the MagSafe charger.
Because it’s not MagSafe certified, that means the recharge capacity of the Snap+ Juice Pack Mini is just 7.5 watts — half of what “true” MagSafe is capable of.
However, if you bring along a USB-C to Lightning cable and recharge that way, it increases the output to 12 watts.
That major caveat aside, as a small, pocketable 5,000 mAh battery pack, we like the Snap+ Juice Pack Mini a lot. Mophie says a fully charged battery can give an iPhone 12 in default settings a complete charge from 0 to 100%.
Both the iPhone 12 and iPhone 12 Pro feature 2,815mAh batteries. That means owners of the iPhone 12 Pro Max, which boasts a 3,687mAh battery, won’t get a complete recharge from this accessory — but they will get some extra juice to finish out the day, if necessary.
In our own tests, with an iPhone 12 Pro, the handset recharged at a rate of about 1/3 capacity per hour (slower, naturally, as the phone approached 100%), but with enough juice to top off a near-dead phone. Recharging was a bit faster — about half-capacity in an hour — when using a USB-C to Lightning cable.
And for recharging the battery pack itself via its USB-C port, that was accomplished in about two hours.
Another plus of the product, along with the rest of the Snap accessory lineup, is that it comes with a “Snap Adapter,” a metallic ring with an adhesive that can be attached to non-MagSafe compatible devices, like the
