As someone else mentioned it's 1-9W not 1.9W for the H3 and H3+.
I don't particularly trust the numbers, generally the N6005 runs hotter than the N5105, which makes sense since it's the same process and largely the same chip with more GPU EUs.
ServeTheHome mentions VERY similar boxes (same CPUs) "At idle, we saw between 10-12W depending on single versus double SODIMM configurations. Maximum power consumption hit just over 30W. Both at idle and at maximum, this is significantly higher than the J4125, but one also gets more performance, so there is a clear trade-off. At the top end, adding ~5W over the N5105 was unexpected based on similar TDPs."
On the N5105 (they reviewed at least two) "Power was not a winning point of this solution. At idle, we saw between 10-12W depending on single versus double SODIMM configurations. Maximum power consumption hit 24.5W even with the Topton configured (512GB/16GB) unit. There is clearly room to go up from there. This is a lot higher on both idle and maximum power consumption than the Celeron J4125 that we looked at previously."
I suspect that H3/H3+ numbers are on the DC side with an eMMC module, a single DDR4 SO-DIMM of the lowest capacity, with the most aggressive power management settings, and nothing else attached. 1.9w idle is plausible but not what people are going to see with a realistic running configuration measured from the AC end.
