Recently, Twitter account @ArchiveInternal netizens shared the prototype version of Apple's MagSafe external battery: using a smooth white plastic shell with identifier information printed on the side. Unlike the final retail version, the original rear surface material does not have an embossed MagSafe alignment ring and has an LED at the back.

Through the pictures, we can also see that the prototype still has a blurry circular outline, indicating the presence of MagSafe technology. The prototype may simply be missing the extra rubber layer on the final MagSafe battery.
The MagSafe external battery reportedly encountered development issues and software issues before the release, and since its release, users have reacted to the accessory in mixed reviews.
