Anker PowerCore 13000 C, $28

Anker recently made a new version of its popular PowerCore 13000, this time with a USB-C input port. To be clear, that port won’t charge your phone; it’s only for recharging the battery itself. But that means if you already carry a USB-C charger for your phone or laptop, you can use it for your battery now too, rather than schlepping a gross old microUSB cable with you.

$28 is an all-time low, and it’s actually $8 less than the old, otherwise identical microUSB version.
