I’ve had no difficulty width 3b+es and phone power supplies with a 2a nameplate rating.  It is highly likely that freebie grade micro usb cables (and ohms law and 28-30 awg wire) are to blame.  Consider trying Anker or other higher quality cables that are rated for fast charging of phones.

Speaking of which if you have a herd of tiny ARM devices that want 2 amps, I’ve found that the 6 port 60w Anker power supplies are most excellent for the workbench or rack.  They also make nice presents/stocking stuffers.  https://www.amazon.com/dp/B00P936188

And yes, they now have versions that do usb-c if your newest phone needs that.  Anker makes good quality products at the right price.  Two thumbs up.

Also, yes, dhcp leases are sticky by MAC address.  They tend to not be durable across router reboots though unless you have an environment where you can make the lease permanent. If you have a Linux box you can use nmap to scan your subnet and find your stuff (and if you run it as root it will tell you about the OUI in the MAC address which can be handy,

Lastly, since you have a herd of these beasties, on Raspbian at least you can set them up to run sshd out of the box, which eliminates the need to set up a console for one that is freshly installed.  Wouldn’t surprise me if other distros follow this.  https://hackernoon.com/raspberry-pi-headless-install-462ccabd75d0
