honestly i've been through so many of these and most are kind of a letdown tbh. the iphone 14 pro max has such a huge battery that these little 5,000mah packs barely even get you to 60 or 70 percent before they tap out. the physics just aren't there because wireless charging is incredibly inefficient... you lose a ton of energy to heat which then makes your phone throttle the charging speed anyway. i tried the Apple MagSafe Battery Pack thinking the official one would be better but it was honestly pretty disappointing for the price. it integrates well with the lock screen but the capacity is tiny. if you really want one though, the Belkin BoostCharge Magnetic Wireless Power Bank 5K is probably your best bet for build quality. it stays cooler than the generic ones i found on amazon but it's still just a slow 7.5w trickle. if you're doing anything intensive like navigation while charging, the battery level might even stay the same lol. just keep expectations low on the speed side.

The Anker 622 MagGo is hands down the best. 5,000mAh capacity, strong magnets, and charges at full 15W. Been using it for months and the kickstand is super useful. Worth the $80.
