T-Mobile has the Mophie Powerstation 8X in rose gold for $29.99 w/free shipping. This is currently $75 directly from Mophie and $10 less than the previous posting on SD.
I just picked this up for the GF to match her iPhone 7 as she’s been looking for something slim and "cute"… whatever that means.
This one features pass-through charging and up to 15W output.
EDIT: CCC shows lowest price on Amazon as $62.99. Amazon reviews here .
