The Practical Meter sheds light on smartphone charging times

Ok, so the cheaper price is for a cable and not the meter at all? Even while the real tech here is the meter? Is that a typo or just nonsensical? edit: I checked and it's just nonsensical.
Either way i totally want one but not at all for charging a phone. I have no smart phone, tablet, etc. I suppose i'd use it on my Raspberry Pi to monitor power use during different OC profiles or running a game like minecraft, Or just as curiosity on everything from my KB, mouse, mic. Could be a nice tool, a fine tuning kill-a-watt on the other side of the circuit. And it lights up, who doesn't like that?

Doesn't the size and the state of charge of the battery also determine the charge time? If the battery is only 30% down when you plug it in at full power, it will charge a lot quicker than if it were 90% depleted.
It seems that to be really Smart - it needs to know the state of the battery before charging starts, and the capacity of the battery. Otherwise, it is just a wattmeter.
I'll have to check the Kickstarter site to see if there is more information.
Meanwhile - this should be built into the phones!!

On my Android device a battery saver/level indicating application gives me an option to display time to charge to 100 % AND time to discharge at present usage level. To do this it senses battery level and the charging current. I find it to be within 95 % accuracy range. Why do I want this gizmo???
BTW as the battery voltage level builds up the charge current will drop !

yep a phone app would tell you exactly not this thing that doesn;t know what the battery can hold or what the initial charge state is
