Today's Dealmaster is headlined by a discount on Anker's PowerCore 10000 PD Redux, a USB-C portable battery that we've previously reviewed and recommended in multiple buying guides. It's down to $30 on Amazon today, which is only $1 more than its all-time low and well below its usual going rate of $46.

We recommend the PowerCore 10000 PD Redux primarily because of its portability. It measures 106i-52.3i-25.5mm, making it noticeably shorter than the average smartphone, and it weighs just seven ounces, so it should fit more than comfortably in many handbags or (men's) pants pockets. It pairs that size with an 18W USB-C Power Delivery port, which is fast enough to charge most modern smartphones (including new iPhones) at maximum speeds. It's worth noting that new charging standards should increase smartphone charging rates even further in the future-devices like Samsung's 2020 Galaxy phones already accept more power with first-party chargers-but since power banks with those improvements aren't yet common, we think this Anker model is still a good value for a travel battery at $30.

Either way, the PowerCore has a 12W USB-A port alongside the PD port that lets you charge two devices simultaneously, albeit at a maximum of 18W combined. The battery's 10,000mAh (36Wh) capacity should be enough to get two full charges out of most phones. Anker includes an USB-C to -C cable in the box, and the device is covered by an 18-month warranty.
