Thanks everyone! Nailed the answers so quickly. I ended up buying the aeotech z-wave one this AM - $72 AUD delivered. Pricey, but i figure this can be my “polished” roving one around the house when im curious about power draw. The small profile, changing LED color per power draw amount, and USB power ourlet out the side justified the purchase. Ill keep an eye out on the kogan ones though also for the cheap and cheerful more perm ones. How much is sale price ? (Showing about $70AUD for 4 now - which is already pretty good!).
