Due to space constraints of where I'm placing my hub, I'd like to use a different power adapter for my Hubitat Elevation hub. Is a standard iPhone brick rated at .15A sufficient? The supplied adapter is rated for .3A. I want to make sure this won't cause issues with the hub.
Thanks!
Welcome to the community...
I have mine on a multi-usb device that powers multiple usb devices...
I don’t think I would go down in amps.. Going up is always a safe bet
I only mention the multi-usb because you mentioned space constraints
I use this to power 4 of my 6 Hubitat hubs, plus 2 Raspberry Pi.
<-- at Amazon
The supplied power brick for my C-5 hub is rated .15A
Just curious, I thought I read in some earlier posts that the C-5 hub was supplied with a 1A adapter and it was thought that might be marginal.
I know for a fact that my C4 draws between 0.3A and 0.6A. I though the C5 was at least similar.
Does the C5 really have a much lower power draw or am I missing something?
Thanks for the warm welcome, and for some alternate suggestions!
Sorry I should have been more clear - the DC output power rating on both adapters is identical (5V, 1A). But the input rating differs, which is what I referred to in my original post. I figured this would be a great place to clarify whether or not one of these ubiquitous adapters would be safe with the C5 hub. I thought someone else would've tried this by now.
In my case, the iPhone adapter would be the simplest and cheapest option for fitting my hub into a multimedia wall cavity that has an electrical socket in a tight space.
Another option:
<-- I rather like Native Union charging cables.
That's pretty
Most A/C to DC adapters are of similar efficiency. Small variations in input current from unit to unit is more likely how conservatively the company wants to be in there ratings.
As long as it is UL listed you should be fine.
My c4 hub draws about 700 mAh on startup, but I don't know what would happen if less were delivered at startup.
After startup the power draw is very small.
Here's the current my C4 draws on power up. Note the 5V supply is from a laboratory supply with capability of > 5 amps
Data Description:
Dark Blue line, hardware is starting up
Orange line, hardware has settled down and processor is about to start
Green line; processor booting. This ends at 2:20 minutes:seconds (0.5 - 0.6 amps)
Light blue; processor bouncing between idle (0.3 - 0.35 amps) and active (0.5 - 0.6 amps)
Red line; processor shutdown, only power supply and red LED is active (0.050 amps)
Peak consumption is approx 0.8 ampsI wonder what the data would look like for a C-5 Hub with an external Z-Wave USB stick? I wonder if that combination would ever peak above .8A? If so, it might make sense to use a 1.5A-2A power supply.
I don't know, I only have the C4. I tried looking at what might be different with the external stick brought inside. The best I can see is the reduction of one 5V to 3.3V supply, believing the C4 has one in the unit and one on the stick.
Anything closer I would have to test a C5.
Which bench supply are you using? I'm looking at adding another one to my fleet---I've never thought about getting one that has the capability to graph data 
Unfortunately, my supply doesn't log anything. Its a small HP supply.
I measured the current with a LEM-15 hall sensor with a custom built circuit and board. Logging was done with a Measurement Computing USB DAQ.
