If you don’t need a ton of power while on-the-go, perhaps you’ll be happy with Heloideo’s 10000mAh Power Bank at $40. I’ve owned one of these for about a year now and use it non-stop. Its selling point is that it sports built-in charging cables for USB-C, Lightning, and microUSB. It can also be plugged directly into the wall, allowing you to ditch cables while mobile.
