ZeroLemon iPhone 7 Plus Battery Case, $40 with code P8H9ZHRO

Plus-sized iPhone owners have traditionally been left out in the cold when it comes to battery cases, but ZeroLemon finally made one for the iPhone 7 Plus, and you can get it for $10 off with promo code P8H9ZHRO.

The 7 Plus is a big phone to begin with, so I’m not sure I’d want to use this thing full-time, but it could really come in handy for long days with few chances to plug in.
