I know the 2.1 amp chargers are different, but I see a lot of 2.0 amp chargers being sold. Is there a difference between the new Motorola Turbo Charger and all other 2.0 amp chargers?
[X 2014 Accessories] borxnx:
Yes. The Turbo Charger uses higher voltage and scales down as the phone battery becomes more charged. Not sure what the amperage is on them, but the key here is the voltage.

Most, if not all, phone chargers these days are 5V, X.XA. The Turbo Charger is 9.somethingV.

[X 2014 Accessories] dianestory2:
Again, for the Moto x (2013) where can I get one of these?
[X 2014 Accessories] stastnysnipes26:
Doesn't exist. The 2013 doesn't support turbo charging.

Well that stinks...
[X 2014 Accessories] stastnysnipes26:
My girlfriend is disappointed too. Turbo charging is gonna be a life saver.
[X 2014 Accessories] dianestory2:
Oh well... I suppose this is the negative side of not upgrading all the time.
[X 2014 Accessories] Badelhas:
So, to whoever bought a quick charge 2.0 charger: is it worth it or not?
[X 2014 Accessories] stastnysnipes26:
Absolutely. I charged my phone from about 26% to full in under an hour.
[X 2014 Accessories] distortedloop:
Turbo charger takes my phone from 4% to %36 or so in just fifteen minutes.

I only charge my phone fully overnight so I only have one sample of going to 100% with that I timed. It was somewhere between 90 mins to 2 hours from a dead battery.

Is it worth it? Depends on how often you'll be in a situation where you need a 30% bump in 15 minutes to get you through the end of the day. It's pricey, but I don't regret it... I think of it as early adopter tax. I'm sure cheap knock-offs will be along eventually.

Do you have the official Moto turbo charger?

Yes, I do. Two of them, actually. One for the house and one for the office.

[X 2014 Accessories] distortedloop:
Little bit of an update. I'm sure the phone controls the charge rate, but the Turbo Charger doesn't turbo charge unless the phone has a very low battery.

Example, from 4%,it will go up to 36% in 15 minutes. But from 79%, it only takes the phone up to 93% in 20 minutes. That is the exact same amount that my Anker 2 amp charges the phone in 20 minutes.

This is a bit of a disappointment; I'd hoped to get back to 100% in that amount of time. Looks like it only accepts faster charge rate with lower charge states.

[X 2014 Accessories] distortedloop:
Whatever the reason, it's disappointing. I won't say false advertising, but unclear at best in the product description at the time I purchased it.

Call me stupid, but I checked your link and don't see an explanation for why it only rapid charges at the bottom half of the current charge state. Could you be more specific?

I'd just assumed it was a heat control thing.

One thing I saw was the LG G3 on the compatibility list. I'll have to see if I get anything noticeable on my G3 with the Turbo Charger.

Thanks.

The voltage is higher at the beginning and lower towards the end to protect the longevity of the battery
[X 2014 Accessories] distortedloop:
Yeah, that makes sense and is in line with what I thought, but there seems to be a window or floor above which the higher voltage isn't allowed. I'll have to test more to see what it is.

Just now, in 25 minutes the phone went from 34% to 81%. That's pretty fast and gives me more than enough juice to make it through the evening.

Slightly less disappointed now.

[X 2014 Accessories] GatorsUF:
I thought they were pretty clear about how it functioned. It's intended to get you some juice when you really need it, not exactly to fill the battery all the way up right away.
[X 2014 Accessories] distortedloop:
Well, why be arbitrary about what point of current charge defines "when you really need it"?

Before I left the house this morning, I noticed just 79% battery and felt I'd needed 100% to make it through the day. I "really needed" that extra charge to get through the day, but they didn't allow it.

Anyways, no need to quibble back and forth about it.

Hello to every one!

i have the moto x and try to use a fast charger, but i don't find any in the vicinity.

i bought the Anker 40w 5 port charger that deliver maximum 8a on 1 usb, but with the Currentwidget i see only 1,2a.

i try the samsung's tab s charger (2,1a) and is the same.

can you try with one widget to see how many mah deliver yours? Thank's!
[X 2014 Accessories] qwerty12601:
Lol really? You're using semantics. Obviously you "really need" a quick charge when you only have 15% as opposed to 79%. They were clear about how the charger works. If you're low on battery, and need a quick charge this provides you with a significant bump in power in a quick time to keep your phone from dying...
[X 2014 Accessories] distortedloop:
Again... Why be arbitrary about at what point higher voltage charging is allowed?

As it works now, I withdraw my buy recommendation and make it a don't buy unless you're someone who really might often be in the situation of not being able to charge the phone to acceptable levels during the day, but somehow manages to get to a place where their $40 Turbo Charger is, and a quick 30% (or less!) charge will help them.

I don't see that being a common scenario, at least not for me or anyone I know. Travelers maybe, but for most of us, a cheap 2 amp charger will be just as effective in most scenarios.

Will I bother returning mine? Probably not, but because I'm too lazy to call Motorola, not because the product will add meaningful value to my user experience.

Sent from my XT1095
[X 2014 Accessories] qwerty12601:
Lol there's nothing arbitrary about it! Its more important to get a quick charge when your battery is low as opposed to when it's over 75% full! Who hasn't been there when you only have a few minutes near a charger and you only have 15-20%? Getting a big boost in 15 minutes is a life saver.

Do you fill the fuel tank on your car when its at 3/4, or when you're at 1/4 or near empty? Do you fill your dogs bowl of water when its barely empty, or when it looks low? Humans are all about replenishing things when they're low. Thats just what happens. And getting a 70% charge in 15 minutes when your battery is about to die is much better than waiting an hour to get 50%.

---------- Post added at 08:58 PM ---------- Previous post was at 08:56 PM ----------

And the whole point of limiting the turbo charger when the battery is 70-75% is to prevent over charging, damage to the battery and phone. Its much less likely to overcharge a battery if you limit the turbo charging to work between 0-70%
[X 2014 Accessories] distortedloop:
It is arbitrary, and I don't believe a fast charge from 70% to 90% would damage the battery any more than getting 30% from a <5% starting point.

I also believe that you're just being argumentative. Based on your comment about getting a 70% charge in 15 minutes suggests you don't even own one of these, and have no idea what its capabilities are. Come back and defend the product after you've actually used it.

You do not get a 70% charge in 15 minutes no matter what the starting point is when you start charging. From under 5%, in multiple tests, the most I've ever gotten in just 15 minutes is a bump charge of about 30-35%, tops. From starting points as low as 45%, I've never gotten anything faster than my 2-amp charger gets me.

For most people, given the limitations of this things fast speeds, I don't believe it is a good value at the price it sells for. Who doesn't have a USB car charger to get a bump while in transit? Who doesn't have access to a charger at their desk, or at their home that will serve them better in the vast majority of the time? Who doesn't already have some external charger to throw in their backpack for when in need of a boost?

I've got money to burn, but many in these forums don't. I bought two of them, and don't regret it, but as I said before, I can't recommend it to those who think $40 is a lot of money. The specific conditions under which there is any benefit to using this charger are not impossible, but if they're common, you're doing something wrong.

To your non-phone battery illustrations of human nature:

Back when I drove purely gasoline powered vehicles, I would fill my tank at whatever time is convenient and that I feel is necessary to avoid needing to get fuel at an inopportune time. So, yes, if I had 3/4 of a tank and was going on a drive that 3/4 of a tank wouldn't get me all the way, whereas 100% would, I would fill the tank. I currently drive a plug-in hybrid - and I charge the battery WHENEVER I have an opportunity to, and it doesn't care if it's high voltage or low voltage charging, or what starting point I'm at...it sucks the juice as fast as it can.

I fill my cat's water bowl whenever I see it doesn't have enough water in it to last until the next opportunity to fill it will be, and guess what, when I fill it, even when it's already half full, I don't pour the water in slowly. LOL

Do you really want to argue about my opinion of a product you clearly haven't used?

Edit: all that said, I do see that one of the footnotes/fine print items on the charger's page says "battery must be substantially depleted; charging rate slows as charging progresses." That still doesn't change my opinion of the thing's value
[X 2014 Accessories] borxnx:
Your "belief" vs. science is what's arbitrary. I can "believe" that water flows uphill all I want. Voltage must increase and wattage decrease as the battery is charged to prevent damage. Charging balls-out at over half-capacity will render a Li-ion useless. If these phones had a removable battery it'd be much less of an issue.

If the link below is removed, a simple google search will be quite informative.

[X 2014 Accessories] qwerty12601:
You're absolutely correct. I don't have one, and STILL know how and why it works the way it does. You on the other hand, bought it without bothering to read how it works, why it works the way it does, then come here to complain because it doesn't work the way you believe it should when it was clearly advertised EVERYWHERE how it works.

You've made it very clear the mentality of the individual I'm debating with, and I've now deemed it pointless. Enjoy blindly "burning" money ;)
[X 2014 Accessories] distortedloop:
Almost TL;DR, but I did. I don't see where a rapid charge from 70 to something short of saturation will destroy the battery, but I'll concede your point anyways. I'm not sure how quickly that would occur at any rate, and given the relatively short time many on these forums hold onto a single device, I don't know that it would be an issue for most.

I do see where in that article you got the misperception that the Turbo Charger will take the phone from dead to 70% in 15 minutes, but let me assure you again that it doesn't.

The article seems more focused on charging current as opposed to voltage. The Turbo Charger uses higher voltage to work is magic.

I'll assume that since you didn't dispute my assertion that you clearly don't have one of these Turbo Chargers, that I was correct. With that in mind, your condemnation of my opinion of the value this Turbo Charger product considering the cost/benefit ratio for it versus its performance relative to any far cheaper 2.1 amp under most conditions is meaningless.

Go buy one and tell me after a month if you feel the limited conditions it works as a turbo charger are worth the step premium price.

For anyone curious for some stats, I just got my Turbo charger and let my phone run completely dry. After a timed 15 minutes (only booted up after the 15 were up), my phone was at 29%. After a second timed 15 minute segment, it was at 57%.

That's not as good as I'd hoped, but it's certainly better than any other charger I've used.

Got my turbo charger today. Plugged my Moto X 2014 in at 26% and it is now at 63% after just 18 minutes. The phone got a little warm at the beginning, but now I believe the charging is slowing down and the phone is back to normal temp. I'm not sure if it is good for the battery to get warm for a short period every night, so I might just switch back to my regular charger for overnight use and just use the turbo charger for emergencies during the day...
[X 2014 Accessories] Shadowdancer123:
Yeah, definitely don't use the turbo charger every night.

It's more for topping up before lunch if you believe you will really need it etc.

The battery wears much faster, and I'm surprised there hasn't been any warning about this anywhere.

With my RC quadcopter I charge 1C at most, which is 5000 mA to a 5000 mAh cell.

Using 2C heats up even that huge 200 gram battery.

The turbo charger is capable of delivering 3000 mA, which is a little bit more than 1.3C..

I wouldn't hesitate if the battery was removable, but not with an integrated battery like this.

Just my thoughts. =)
[X 2014 Accessories] ssick92:
The thing that made me think that it wouldn't hurt the battery is the fact that the Droid Turbo comes with the Turbo Charger as it's stock charger in the box. Motorola would HAVE to assume that people are going to be using it everyday, and I find it hard to believe that they would ship the phone with a charger that will ruin the battery over time...

I won't be using it nightly because I don't like how warm it gets, but I also find it hard to believe that they would sell a charger that would ruin batteries....
[X 2014 Accessories] rvbarton:
I bought my turbo-charger based on this article. http://www.techanalyzer.net/2014/11/03/htcs-rapid-charger-motorolas-turbo-charge-worth/

States

"So when it comes to the Motorola Turbo Charger, the HTC Rapid Charger and any other Qualcomm Quick Charge 2.0 chargers that will come along the way, in terms of battery deterioration, there’s nothing to worry about.

So is Quick Charge 2.0 chargers worth the battery deterioration? The simple answer is that it won’t cause any harm that’s not expected for the duration of the average battery life."

Hope that really is the case. I haven't used mine yet, but keep it in my bag if I need a quick charge...
[X 2014 Accessories] ssick92:
That's what I assumed, but it is scary having your phone getting pretty warm when it charges and I'd rather only have that happen when I really need the extra juice. I realized that there is exactly 0 necessity for me to use the turbo charger every night since what is the difference if it takes 1 hour or 3 hours to charge since I am asleep anyway... But thanks for the info, now I won't be as scared to use the turbo charger whenever I want.
[X 2014 Accessories] Shadowdancer123:
Strange, but I guess the expected life is no more than two years. My old XT910 still works fine after four years, and two years mistreated post-retirement as a wireless RC camera. :P

Heat is the killer for everything electronic, batteries are no different. Especially since they contain alcohols that easily evaporate and boil.

I wonder if the turbo mode can be altered in software? To allow slow charge nightly and such?

Even if the calculated life is similar, I know I will never trust Li-Po 100% for safety when they warm up.

I accidentally left my phone under my pillow during the night charge, it was still scorching hot when I woke up...

I know they've added temperature sensors and such, and arguably, they only charge a certain range at maximum amperage.

When I charge my RC models they run max amp until the very end of the cycle, heating them a lot more for sure...
[X 2014 Accessories] Badelhas:
I am sorry but I refuse to believe that they invented a technology that damages the battery
[X 2014 Accessories] Shadowdancer123:
Well, when you think about it..

I know that virtually all battery technologies have their lowest internal resistance somewhere between 25-75% charge.

I guess it's possible that the wear, if you extremely accurately monitor temperature, charge state and resistance, is minimal.

My RC chargers do it the old fashioned way, just ramming those Amps until it stops accepting charge.

EIther way, I would use it sparingly until I've seen what experiences pop up in forums a year from now. =)

[X 2014 Accessories] l_stevens:
There's no getting around physics. Heat deteriorates batteries. Period. Faster charging will create more heat. Period. So, using the Turbocharger WILL deteriorate the battery faster. How much faster is not known. It is advisable NOT to use it as your daily charger, but only when necessary if you wish to keep your battery as "young" as possible.
[X 2014 Accessories] Badelhas:
conspiracy theories
[X 2014 Accessories] l_stevens:
Yes, and some people still think the world is flat! :cyclops: However, as a Particle Physicist, I don't entertain many conspiracy theories! Anyway, science aside, my "theory", (what I stated in my last post is basic physics/fact), is that the deterioration caused by the Turbo Chargers extra generated heat/resistance is low enough that the manufacturers don't care about the loss of charging ability because of their use, figuring that you'll get a new phone in a year or two. They're all about convenience (that's what sells phones), and don't care if you lose 10-20% more capacity over time. For my money I need every minute of an already too small amount of battery capacity, so I'll use mine only when necessary.
[X 2014 Accessories] shamelin73:
I just received mine and will use it when traveling as I am away from the house 60% of the time I would consider it to be my primary charger. They wouldn't have included it with the Turbo or the Nexus 6 if they thought it would damage the phone.

I also have the Moto care insurance if it causes issues after the 1st year.
[X 2014 Accessories] l_stevens:
It won't "damage" it; only reduce full charge capacity an unknown amount over time. But, you DO bring up an intersting question. At what point would Motorola consider the battery's charge capacity low enough for a replacement?
[X 2014 Accessories] spongers:
You're making one very large assumption, that charging it faster creates more heat. My understanding of the Algorithm used in the Qualcomm circuitry is that it prevents this, or tries to. As it charges the phone, it slows down the charge itself, depending on the percentage the battery is at at the time.
