Indoor only but would work in a watertight outdoor enclosure too.
AmazonBasics 5FT 3 Outlet 3 USB Port Power Strip Extension Cord (1 USB-C and 2 USB-A)
$6.99
2x USB-A ports with 12 watt each (enough for any wyze model)
1x USB-C port with 15 watt (use with USB-C to micro USB cable to run a 3rd cam, or C to C for the cams that have C ports)
17 watts max across all 3 USB ports, enough for 3x 1 amp cams, and probably would work for a single 2 amp cam plus two 1A cams, as long as you don’t use all the features at once.
3 standard AC outlets up to 1875 watts total on those
It would be nice to have one like this with more USB ports and no AC ports, and a very small end to make it easy to fit in a small water tight box, Probably are ones like that out there, but these two are pretty reasonably priced. I’ve generally found Amazon Basics stuff to be good (not that they are fool proof, it is just a white label of whatever company they contracted with).
