INIU Portable Charger: was $29 now $17 @ Amazon
I always keep the INIU 10000mAh Portable Charger in my work drawer because of its compact size and utility, which is made better by the fact it doesn't cost a whole lot. While it lacks the faster charging speeds and spiffy designs of other chargers, this INIU one gets the job done.

Newdery 10,000 mAh Portable Charger: was $35 now $25 @ Amazon
There's something about transparent designs that always gets me. The Newdery 10,000 mAh portable features one that lets me see through its casing, all while being able to charge my phones and Apple Watch.

Mregb Portable Solar Power Bank: was $89 now $35 @ Amazon
For anyone planning to go off the grid, or taking a long weekend for camping, the Mregb Portable Solar Power Bank is one to carry along because of its ability to charge with sun power. You won't have to find an outlet to recharge its 42,800 mAh battery because you can leave it out for periods of time thanks to its integrated solar panel.

LISEN MagSafe Car Mount Charger: was $39 now $19 @ Amazon
You don't see this type of portable charger often, but what I love about this Lisen MagSafe Car Mount Charger is that it serves double duty for your iPhone (or Android with a magnet mount) and Apple Watch. It sits directly over a car vent, which will also provide your devices with adequate cooling while they're charging.

Anker Power Bank Fusion 10K: was $45 now $35 @ Amazon
I really hate having to carry along cables for my phones, which is why I love the Anker Power Bank Fusion 10K. There's already an integrated USB-C that lets me connect it to my gadgets. There's also another USB-C port on the charger itself if I want to charge something else at the same time. And best of all, it acts as its own power adapter with its fold out charging clips.

iWALK LinkPod 4: was $26 now $18 @ Amazon
When you really need something ultracompact without having to worry about pesky wires, the iWALK LinkPod 4 offers instant charging by directly being attached to your device's USB-C port. Its 4,500 mAh battery capacity might be small compared to the others here, but it should give most phones a fair amount of charge.

Baseus 30000mAh Portable Charger: was $59 now $29 @ Amazon
It looks like a polished brick, but the Baseus 30000mAh Portable Charger has everything I want in a versatile power bank. In addition to having USB-A and USB-C ports, it even fashions in a microUSB port as well if you have older devices that still use it.

HUOTO Portable Charger for Apple Watch: was $25 now $17 @ Amazon
Yes it's a specialty charger for just the Apple Watch, but what I love about this one from HUOTO is that I can clip it onto my keychain so that I can use it whenever. With its 1,200 mAh battery, it's more than enough to at least give the Apple Watch a single charge.
