Traditionally, the danger with fast charging is shortening the longevity of the battery. If "smart" charging of modern battery types avoids this, by accurately monitoring battery status during charge and adjusting charge power accordingly, and can therefore avoid that pitfall, then this sounds like a great option.
Personally, I tend to charge devices (like a tablet) that need daily charging by charging overnight. But for those that don't, or simply forgot, this could be a good option. I'd need to see more details before buying, though.

I do the same, over night charging for my phone. My only problems with this are:
1)You have to make it through the day if it's going to be your only charge! :P
2) My phone might take 3 hours to charge from dead but it's then sip charging for the next 5 hours which I'm led to believe is very bad for battery longevity.

Making it through the day doesn't seem to be a problem with my phone, but hey.
That's not how it works though, 3 hours to charge from dead is fine but after that the phone draws all its power from the charger not the battery, the battery is essentially totally disconnected at that point. When the battery drops to 95% due to self-discharge (takes 6 months for a full self-discharge, not sure about how long it'd take to go from 100 to 95 but probably more than a week) the phone will charge the battery again. Trickle charging should therefore never happen.

Simple mechanical or digital plug-though timer solves that. Set it for 3, maybe 3.5 hours. Job done.
I do this with domestic DECT phones, too.

It can occur if the phone is on - which mine is when charging over night.

What you're saying pretty much explains the behaviour of my LG G3 when on the inductive charger. There once it gets to 100% you can take the phone off the charger and put it back on again and you don't get the "charging" icon. Oh and it also gets through the day on a single charge (unless you spend a lot of time playing games - especially Smash Hit - that puts that power vampire screen on).
Was initially kind of interested in this fast charger, but on second thoughts (especially at that price) I'd rather not take the risk of any battery damage and just buy a second LG charger.

Li-ion batteries are *not* trickle charged; unlike nickel and lead-based chemistries, li-ion cannot accept and dissipate a trickle charge safely and attempting to do so is extremely dangerous, it's not just a case of shortening battery life. For this reason, no proper li-ion charge controller will continue to charge once the battery is 'full', and as CampGareth said, may restart charging if the battery drops below a certain voltage.
As I've said before, this is why the 'leave the phone on for x (often 14) hours for the first charge' you still see in some manuals is complete crap left over from the days of nickel batteries. Once the current to the cell drops below a set point (often something around 0.1C depending on chemistry and structure), the charge is ceased.
You'd know about it if phone batteries were being trickle-charged, and it wouldn't be through shortened life. :boom:

Pretty sure my G3's manual (or the quick start) said something like that. But in their case I think the stated justification was to make sure that the battery was at 100% before you started playing with your new shiny-shiny.
The other "myth" I've seen (unless you're going to tell me that it's true - in which case it's red face time for me) is that you should never use a "tablet" charger to charge a normal phone - that the increased current will cook the battery. I thought (99.9999% sure) that a phone's charging circuit will only draw what it needs from the charger. So a 1A phone will still only draw 1A, even if connected to a charger capable of supplying 2A.
Re: News - Motorola Turbo Charger: 8hrs of battery life from a 15min charge
Yep, also a myth. The charge controller sets the charge rate, not the USB power supply. There are times when doing the opposite (e.g. low current phone PSU with high current draw tablet) could cause issues if one of them doesn't negotiate current correctly e.g. cheapo chargers. But provided everything actually meets spec, you can mix and match as you please, which is the beauty of a unified system. Well, everyone bar Apple of course...

True enough, though.

But with a lot of phones, by the time you wake up it will be at 95% or something like that. Most modern smartphones wake themselves up automatically to check for various notifications and other things too.
