MagSafe battery packs are a genuinely useful category, but most of them add enough bulk that the phone stops feeling pocketable the moment you snap one on. Anker’s Nano power bank solves that with a 0.33-inch profile and Qi2-certified 15W wireless charging. Right now on Amazon it’s down to $45, off its $54 list price, which is the best price this power bank has sold for since launch.

0.3 inches thin, Qi2 certified, 15W max
The Anker Nano measures 0.33 inches at its thickest point, which puts it roughly in the same thickness range as a standard passport. That is not a meaningless vanity spec: thinner means the phone stays pocketable while charging, which is the entire point of a MagSafe power bank. Most competitors in this category add enough bulk that the phone-plus-battery combo becomes awkward to hold one-handed, which defeats the purpose of a magnetic wireless charger you are supposed to carry everywhere.
Qi2 certification at 15W max means this charges an iPhone at the fastest speed the wireless standard allows. Anker’s internal testing puts an iPhone 16 Pro at 25% after 42 minutes of wireless charging from flat, which is a meaningful number for a top-up during a commute or between meetings. A USB-C port adds 20W wired output for everything else in your bag.
