As part of its 4-day Sale for the 4th of July, Best Buy offers the Mophie Juice Pack Helium iPhone 5/5s battery pack in silver for $39.99 with free shipping. That’s 50% below retail and the best current price we were able to hunt down. Also, keep in mind that it’s rare to see any significant discounts on Mophie gear from reputable vendors.
The Juice Pack Helium arms your iPhone with up to 80% more battery life in an ultra-thin design. Use the included micro USB cord to charge your iPhone and the Mophie battery at the same time. It’s made from a durable polycarbonate to protect your iPhone from bumps and falls.
This temporary price drop may be related to Mophie’s recent announcement that it would soon be shipping a 64GB Space Pack for iPhone 5/5s. It joins the previously released 16GB and 32GB versions as one of the most convenient ways to add storage to an iPhone.
