This is great news if you’re a Samsung Galaxy S3 user who wants more battery: Mophie, who has been making high quality battery-and-case accessories for the iPhone since the iPhone 3G, has just launched a Mophie Juice Pack for the Samsung Galaxy S3. We thought that Mophie’s iPhone Juice Pack was pretty excellent (if pricey) and we love the Samsung Galaxy S3, so this is a match made in heaven. Even more exciting for SG3 users is what this annoucement portends: Android’s anything-goes model means that premium accessory makers avoid the platform, instead opting for iOS devices which are countable and have a large enough market to support the sunk costs that go into designing an accessory. However, Mophie seems to see an opportunity to snag SG3 users–this could mean that Samsung’s ecosystem is strong enough to encourage more cool accessories.

The Mophie Juice Pack is $99 and comes in black or white.
