    As usual, good quality and excellent value from Anker. It's really not that complicated - they make solid stuff, it works as it should, and it's not super-expensive.

    Pretty cool portable battery charger - has two USB-A ports for devices, and one USB-C for charging. It's inexpensive and has a nice carry bag, would have been nice if you could charge with the USB-C port, but for most things it's fine.

    Took a couple of hours to charge fully, but lasted all day and got my phone to max charge after I let it die in about 1.5 hours. Onky negative is if you need a usb-c to usb-c charging port. But I recommend it.
