Few things are more frustrating than having your iPhone battery die on you when you’re running around frantically from meeting to meeting. That’s the price we pay for having such sleek and slim smartphones — but you’ll never have to pay that price again thanks to a limited-time sale happening right now on Amazon.

Trusted Amazon brand Olala is offering coupon codes that’ll save you money on a slender iPhone 6s battery case as well as two different portable charger models. These deals end on September 4 though, so definitely check them out while you can.
