Can anyone let me know the risks, if any, of using the OP7 pro warp charger with other devices? I live in the UK if the voltage in matters.
I wanted to have one charger to charge my OP7pro, Sabatt e12 earphones and Nintendo Switch (undocked).
Anything I should think of? I don't know anything about voltages or fast charging. The headphones say to use a charger that is 5v/1a or "risk damaging".
Can anyone advise?
Thanks
Warp charge is 5v/6a, but whatever device you are charging should limit the voltage and amps. But ultimately yes you could damage your earphones.
It depends. Like Konfuzion has said, every device should have overvoltage protection or something, even earbuds. But it will be better (more safe) to use regular 5V/1A charger instead your Warp charger.
If your device use 5V as a power source, there shouldn't be any problem to use the Warp Charger. I've already used it to charge a Nintendo 2DS and Bluetooth devices and it charges normally, because is the device who control the power consumption (and therefore, the current)
Thanks. I figured because the instructions of the earbuds were specific that it might be a bigger risk.
Thanks. Appreciate the replies. Can I get any cables that would limit the charge? I ask because it would be easier to carry two cables and one plug than 2 plugs. Sorry if that is a stupid question. I know nothing about voltages and fast charging...which should be obvious by now ?

The old dash chargers I believe had some technology that negotiated with the phone before it put out the full amps, I'm pretty sure the warp chargers/cables have that too. When you plug your phone in, you will notice it doesn't warp charge immediately, it charges normally for a second then warp charges, so any device plugged in that can't negotiate with the charger should cap out at 2a,which is where the device your charging's protection comes in. You should be fine
Edit: be careful with your switch though, they are known to brick with 3rd party charges (google/youtube that) but it might have just been crappy 3rd party chargers, I don't have a switch to test

Actually, no. If you use a crappy cable, you could get (at least) the cable on fire (It won't happen, but technically is posible if you made your own cable with a very very thin conductor).
As I said before, is the device who limit the current at charging. In the case of the dash/warp charger, the cable has "a little extra" that allow the high current, and that is why you can't use any cable to get the dash/warp experience (if you want more info, read https://www.reddit.com/r/oneplus/comments/928iqn/whats_the_difference_between_dash_charge_cables/ )

So my DHD arrives tomorrow.
After reading about battery life, I want access to as many chargers as possible.
Can you tell me: Will my existing Micro-USB Chargers (Blackberry) be compatible with the DHD? I'm not sure if each unit will require a specific voltage / wattage?
Or can I just plug & play with which ever Micro-USB charger I come across?
Thank you & sorry if it's a dumb question...
Any cable will do fine. Definitely if you're charging through a PC since I've never heard of a phone/battery that can't handle the 5V it outputs (max for USB charging). A mains charger you can never be too sure with since it may have higher current/watt output, but I've really never let this stop me except that I'd avoid using cheap Chinese knockoffs.
It depends... microUSB connected to computer will be of course good, as it is hardware limited to 0,5A. External chargers are good question, but in my experience the phone/battery usually have a charge limiter so even if the charger does allow you to use higher current, the phone doesn't have to use all the power it can get.
For example i used the Nokia AC-10E charger for my Motorola Milestone since i bough the phone, and had no problems with it. And will use it for DHD too.
The official HTC chargers have an outpur of 5V/1A, so as long as your charger has the same output you should be good.
Nokia AC-10E has 1.2A, but as i said - that is the maximum it can give to the phone, batteries/phones have a current regulators so even if you connect a charger which can give you 2A @ 5V, nothing will happen - the phone will regulate the current which is used to charge the battery.
I am going to buy a car charger for my new HOX, but it only has one 2.1A usb output. I know the charging current of the HOX wall charger is 1A, but I think 2.1A should work fine or even charge faster. But my concern is if the larger current would hurt my battery or shorten its lifetime.
Some ppl said the phone itself would take 1A current anyway due to some kind of threshold control inside, but I am not sure about it. So pls let me know if you know the truth. Appreciate it!
ps. I sent an email about this problem to HTC customer care 2 days ago but still no response yet. I will post the official answer when I get their answer.
UPDATE: Here is the official response from HTC about charging current, it seems that HOX does not intelligently control its charging current:
Dear yydnl,
Thanks for getting back to me, yydnl. The One X was designed with the intention of only using 5V 1A chargers. Anything more will cause damage to the phone over time. The phone was not designed to alter the current coming into the phone through the charger. I recommend that you only use the supplied HTC charger with your device.
Yeah I'd like to know. I never opened the oem charger and am currently using my bb playbook charger which shoots out 1.8A. I'm hoping the answer is no damage with a faster charge.
Yep, it'll work fine. Chargers don't "push" the charge, the phone pulls it. If the phone is only designed to charge at 1000ma, then it will only pull that current. So you could use a 10 amp charger and it will be fine, only difference is that with that high a capacity, you'll be able to charge 10 phones at the full charging rate. Changing the voltage, that's a different story.

There is no problem of the voltage of the car charger because that is 5V as the oem charger, but do you know if HOX is designed to intelligently pull the proper amount of current? or will it take any current fed to it?

All Li-ion batteries have intelligent charging circuits. Otherwise, it will simply explode.
I won't worry about 2.1A at all. The problem is other way around, i.e. whether or not the phone will take more than 500ma from your 2.1A charger. It depends on how your charger is wired. If the phone only detects a generic USB connection, it will only charge max 500ma. It requires special wiring from the USB port to allow phone to switch to AC charging mode to draw more current. Unfortunately, there is no way to tell until you have the charger and try it out. One thing for sure, those chargers designed for iPhone/iPad typically won't be recorgnzied by other phones as AC chargers.

Gotcha, the car charger I am going to buy is for iphone, but it also claims to be able to charge phones of htc, sony etc. So I guess it is possible to have the ac charging detection.

My money is on that it won't be recognized as AC charger. iPhone has special requirement on data PIN wiring that is not compatible with other phone. Yes, you can charge other phones but probably not at anything over 500ma.
Pls see my updates, it seems that 2.1A charger is not safe.
Hi!
Have 3A charger for car (like this) and i want to get maximum power and charging speed. As i know, if i use simple usb cable, phone will get only 500mA.
How to force it to use more power? Or it use it by default, without any mods?
Found this mod for HTC, and this for Nexus 7, does it will work?

I think the mod (shorting the data lines) should work, but just make sure that the charger is actually capable of delivering the right amperage.
whoa, u really wanna do that, coz the wont hold for a long time, 3A really a big current

As of my understanding you are trying to say that charging the battery at 3A would give shorter batterylife.
Would you kindly post in a way readable for humans to make your meaning clear, as your post as quoted here was a struggle to understand.
And for complying to USB standards the device is probably able to output 2A on one of the ports and 1A on the other, totalling in a amperage of 3A. Now as I took a look at the adapter and it's specifications, it seems to me that it is just a 7805 voltage regulator in an enclosure, which I honestly wouldn't trust even a little bit.

I'm not enough of a techie to confirm or deny if this would work, but I do agree with Velihukka... I got a bad feeling about this...
You do realise to get thing working properly you'd need to wire a new 12V circuit into your car's switchbox right? You don't want to be pulling an extra 3A out of a random 12V line in your car, a lot of your internal electrics are only running 10A fuses.
If you don't smoke, you could use the line powering your cigarette lighter... but then that would beg the question, why not just use a 12V USB adaptor that can output 3A and short the data terminals?
sorry 4 my english mate, im still improving it.. yup, i think that can do, but depends on you... i would rather use 2a current output charger... i hope my batttery would last longer lifetime when i used it
You should simply go for this
http://www.belkin.com/in/IWCatProductPage.process?Product_Id=735847
It will cost you around 400 bucks for 2.1 Amp socket in your local car accessories market
And then use your data cable to charge your phone...

It wont work at all for xperia z. i am an hardware tester and i am sure any mods to hack battery life or charging it fast will destroy your battery.
You cannot force more power into the battery. The phone has circuitry that regulates the charging current, which will have upper and lower limits. If that upper limit is say 2A, it doesn't matter if you plug into a 2A power supply or a 50A supply, it will still only draw 2A.
Sent from my C6603 using Tapatalk
The phones circuitry charges the phone by 500mAh by unnamed or unknown usb cable. when you plug it to a sony cable it will give you "fast charge" so it charges with 900-1000mAh. So yeah, there is something in the cable that makes it different from the other ones.
Try it with your sony cable and you get max amperage, and yeah no point forcing a million amps to it when the phone just takes what it needs.

Xz has battery monitor and its the thing that none can bypass. Also everytime the device heats up the amperage going in the battery gets more limited or even depleting...
Defects or flaw I'm not sure, but thats just it with Xz
How would I know what the max current is a device can support like an accessory? So for example, the stock charger that comes with the Plantronics Voyager Edge is only 500ma. What happens if I plug it into a Qualcomm QuickCharge 2.0 charger like what comes with the S6? Will it blow up? Regulate down and charge normally? Charge rapidly?

it will charge normally. it doesnt matter how big the output of the charger is. the phone will regulate it to only what it wants.
only time you will have an issue is if your charger output is too small. the phone will charge slow, and risk damage to the charger.

Does this also apply to the headset I mentioned? How would the current being too low damage the charger? USB ports and car charger are very low current in general

1. yes
2. i didnt say it would damage the charger, i said there is a risk of it. thats because if its too small, the charger is working at maximum all the time.
3. usb's are regulated, not maxing out potential. im guessing car chargers do the same, however im not sure why. likely has something to do with a safe level considering the fluctuation in input voltage from the battery.
Hmm... So what about using a non-QC 2.0 charger (such as some that Anker make) on devices that support QC 2.0? Is there some safety issue or will it just charge slightly slower?

sorry, i dont know about those.
maybe you misunderstood before, i cant think of any common instance where there would be a safety issue.
as unlikely as it is that you will ever burn up a charger (or device for that matter), the only thing that will happen is some small electronic parts will go bad. not some huge fire or whatever. sure on the device there could be a nice exploding fire, but there about always from defect and also extremely rare. it happens maybe 1 or 2 times a year, and its gets posted everywhere, then people think its an epidemic and start asking all these unnecessary questions. im sure the yearly device sales are in the hundreds of millions work wide. if a couple a year blow up, well s happens.
As I'm sure is the case for many of you, I have a ton of typical USB chargers around the house, which supply anywhere from 0.8A to 1.5A output. Going with the assumption that I don't care how long it takes to charge, is there any risk with using the USB C-A cable that came with my pixel and plugging into any of those old USB chargers? They should all work, right? Just as different speeds depending on the output current?
I am not an expert, but from my research into the safety of USB-A to USB-C cables, the "risk" will generally come as a result of purchasing a cheap cable that does not have the appropriate (56k) resistor. The cable that came directly from google has the appropriate resistor and is not low quality, so it will be safe to plug into any functioning USB port (either on your computer or a charger).
That being said, if you have a malfunctioning charger, or there is power surge etc., that is an "act of god" and what happens happens
You may actually be better off using these old chargers if they work correctly. The slower you charge your phone, the better it is for the longevity (years) of your battery.
Yeah, that is why I didn't care about charging speed. For plugging it in next to my bed each night, I figure slower is better. However, I just received a mini USB to USB C from Amazon, and used that to plug my pixel in last night to a 1a charger. And while the phone did say charging over USB, it didn't gain any battery overnight and instead continued to discharge until I woke up in the morning. Is anyone else seeing anything like that?
Not trying to be mean or name call but I personally think you all are crazy. Buying a $700 phone and using a cheap charger that could have the risk to break your phone. Especially if you know better. Honestly, spending the $30-$40 from a charger from Google or an approved charger is just smart for the long term and not risk losing $700. Just my 2 cents. I did the same for the car charger.
Sure, I hear your point. But honestly I know that it is better for the battery to charge slower, so I would rather use a low power charger next to my bed each night, and only use the included quick charger when I need a quick top-off.

Have to consider 2 points since there are so many inaccuracies about this subject:
1) Inadequate chargers with insufficient output cause batteries to become overheated, consequently reduce battery charging cycles. Smart batteries are not adversely affected by certified quick chargers.
2) Turbo chargers do not "top off". When a battery gets to around 80%, the appropriate charger begins its slower charging as to not overload it. Once at 100%, charging stops, and the maintenance process begins. As battery level drops to around 97.6%, trickle charging begins.
In sum, a certified, OEM-equivalent quick charger, even with higher output would not damage batteries.
The phone supports most standards however usb c and Qualcomm quick charge are not compatible and you fall back to 5v 3 amp at best. Make sure to fully insert the cable into the phone. It has to click. I've accidently not charged overnight that way.
I've got a bunch of turbo chargers that I've accumulated over the years. Using a non-[manufacturer of current phone] charger has never damaged my phone. I just bought a 10 pack of USB C adapters and popped one on every charger so I can continue using my old ones. No issues yet and I don't anticipate any.

Sure, you can use non-oem chargers. That's not the problem. Issues only potentially arise when the chargers do not provide adequate output, or their "smart" capabilities are not up to specs. I use all kinds of chargers bought at Verizon, Best Buy, etc. I also use Amazon chargers as long as they're not too far off OEM requirements. Also, people don't think about the importance of a good, thick cable.

Many will say no big deal. However, I'd say let's hear it from the horse's mouth. Here's Google engineer Benson Leung https://plus.google.com/+BensonLeung/posts/cEvVQLXhyRX. You be the judge.
Bottom line, to answer your question, no, quick charging methodology used by Samsung and Motorola is not supported by the Pixel. Your phone will charge at a slower rate. Will it damage the phone in the long run? Likely not. Well, I'll let you guys test for me.
