Mophie Juice Pack for Galaxy S4.

A quick heads up that the Mophie Juice Pack for the Samsung Galaxy S4 — which we reviewed last week — is now available for $99 (plus shipping).

Our take? It's not inexpensive, and we'd still question the necessity of a battery case for a phone that has a removable battery — you can buy a spare and a nice case for less than you'll pay here. But Mophie has done a fine job with this new Juice Pack.
