The iPhone and iPad accessory market is huge, with a solution for every need. Apple itself makes relatively few add-ons, but when it does, it’s something special. Apple’s deep integration between hardware and software allows it to add features that no one else can achieve.

For example, when you go outside, you see people with charging cables running from their phone to a battery pack in their pocket or bag. You even see battery packs attached to phones with rubber bands.

With Apple’s planned MagSafe battery, the whole solution is more elegant: you just stick it on the phone and forget about it. This magnetic battery is another example of the superior accessories Apple can make. Because it owns the whole system, it can add deep-rooted features that aren’t available to other manufacturers.

“Apple has great system integration,” CocoSign co-founder Caroline Lee told Lifewire via email. “Apple has complete control over the manufacturing footprint of iOS devices and their accessories.”
