[Q] Voltage on unofficial micro USB charger

My GF ran over my mains charger cable with the vacum cleanerr at the weekend, so i ordered i new one from Ebay. Rather stupidly (as an "official" one would only be £1 more), i bought this unbranded one:
UK MAINS CHARGER FOR SAMSUNG i5700 i9000 GALAXY S on eBay (end time 02-Apr-11 14:51:41 BST)
When it arrived i noticed that the output is different: 5.5v 500ma as opposed to 5v 700ma from the one that came with the phone.
I know tha ampage will affect charging speed, but am concerned about the extra 0.5 voltage. Is this safe to use?

I'm curious about this too... I thought the "U" in USB meant Universal.
I just ordered 2 micro USB chargers from Ebay for my GF's Sony Vivaz Pro and my Captivate... neither work.
Her's doesn't recognize the charger at all... mine beeps and says "charging", but the battery level never goes up.
My chargers are 5v 500mA.
The chargers were listed as Blackberry chargers, but had a long list of compatible phones underneath (none matched our phones, to be fair.)
Now I'm afraid to buy any more generic chargers....

I don't know if the output voltage is part of the USB standard or not. I know that computers output 5v and it seems like a lot of phone chargers also do. However, i've seen some external battery chargers listed as compatible with the SGS listed as 5.2v, so maybe theres an accepted voltage range? Does anyone know for sure if a 5.5v is acceptable?
I'm not sure why the ones you have don't work as the specs seem right,possibly they are faulty?

Yeah, I'm not sure. I certainly thought so, even though it seemed pretty "unlucky" they both might be faulty.
I did ask the seller, and they claim they are NOT compatible with my phones, but I just don't get it. They're offering me a refund, but at $4 each it's hardly worth my time mailing them.
I found some forums online of a small handful of people like me with chargers that won't work. It seems people with this issue were using 500mA chargers, and anyone using a 700 or 1000 had no problems. This wasn't necessarily because all phones either require 500 or 1000.... Someone also said it's only very certain phones that are built this way. That they require newer, or more powerful chargers... but that it's not the case with all new phones/smartphones.
But there were others who said 500 should charge it, just more slowly.
I still think Micro usb is Micro usb, period. That's why the EU (and here) have been looking at making these chargers universal. I think I'll just try my luck again with another charger.

You could try this one, which claims to be (and looks like), an official SGS charger:
http://cgi.ebay.co.uk/Samsung-i9000...ories_MobilePhoneChargers&hash=item2c5b2d355a

5.5V is supported. I've tested a very wide range of chargers for my SGS and all worked.
The voltage range of these chargers is 4.8V - 5.6V and all worked just fine.

I've actually got an original Nokia USB charger which is declared at 5.0v/550mA and it works like a charm...
Model is AC-6E:

Well finally decided to give the ebay charger a go. Plugged it in, a green light lit up and plugged the phone in. The phone didn't recognise the charger, no indication the the notification bar that the battery was charging. Unplugged it and and tried again, and now the light on the charger doesn't even come on! Won't be using it again.

Another question on the topic : Is it save to use charger with higher Amperage ?
I mean original samsung one is 0.7A, could something go wrong if I´ll use 1.0A charger? Thanks
EDIT : Answer no needed anymore - found it in another topic. It should be safe

I believe any microUSB charger will be safe. Ideally, you want the highest voltage and highest current possible.
I've heard that the phone will use the data lines to tell the USB charger what voltage to set. This ensures voltage compatibility. Then the phone itself regulates the current.. it will only draw as many amps as it needs. So if the PSU can handle 2A, your device may only draw 0.725a for example, but it's safe. You want a high current one to ensure the phone has all it can take.
BTW, I'm not an EE person, so double check what I said.

I fear it's not that simple, especially with dumb chargers that can't negotiate current using the USB protocol, and instead may short the data lines, in various ways, instead to tell the device what current to draw...

There's an explanation here of why different chargers do indeed make a difference:
http://en.wikipedia.org/wiki/Usb#Power
see in particular the note on the Battery Charger Spec.
In particular. my own testing shows I can go from 500ma to 700mA charging current simply by changing a small connector in line between the 7Ahr battery I'm using to charge the phone, and the phone. That's due to the nature of the short on the data pins.
There are proprietary tweaks to this mechanism; e.g. iPhones use voltage signalling between the two data lines and ground to indicate various things to the device.
All of this is only for "hosts", i.e. chargers etc, that don't implement the USB protocol and so can't engage in the normal current negotation that occurs when connecting e.g. the device to a PC.

It's a bit too high.
You have to know that slow charge = long battery life and fast charge = more battery drain after a couple of years maybe months

So usb charging is better then wall charging with original charger? because i noticed that my phone hold it`s charge better if i use the wall charger.

Maybe because the current is higher. My battery voltage is arround 4200mV at 100% and 4100mV with USB
For the solar charger 5.8 is really high but the wall charger is ok

guys can anyone tell me what would be the reason that my Samsung j7 prime charger is giving me 4.63v instead of 5v .. the rating is 5v on the charger. is that possible the ic or some other thing is damaged? in that case what would be solution?

Poor performance of Choetech Adaptive Fast Charger, 5 port 60 watt

I've been a fan of Anker chargers (and other products) as they tend to be high quality and fairly affordable. I have several of the 5 port chargers floating around my home and office that I use to keep various gadgets juiced up throughout the day. I was hoping to find a multi-port charger that was also Qualcomm Quick Charge 2.0 capable so I could bring it with me when I travel. Choetech is the first company I've found on Amazon that advertises a multi-port charger with 2 QC 2.0 capable ports, so I picked one up.
Physically it's about the same size as every other multi-port charger on the market. What's immediately obvious as different though is how light the unit is. It weighs in 5.6 oz (158g) which is less than half the weight of the Anker 60W charger which competes head to head. In this case, I don't think that's a good thing. I haven't cut it open yet but I'm guessing it doesn't have the proper internals to handle power. The other weird physical attribute is that it has recessed USB ports. The actual ports are sunken in by a fifth of an inch (half a cm). I guess the cables can still make contact however, it's a puzzling design decision as you'd imagine that the more contact area the better for power transfer.

Something odd I noticed right away is my Note 4 wouldn't consistently register the charger as fast charger. I swapped out cables, tried unplugging cables from the other ports, jumped and spun around a few times, etc. With my Anker QC 2.0 charger, it would register as a fast charger every single time. I first thought something was amiss after leaving my 2013 Nexus 7 attached to a "standard" port for several hours and then came back to find the battery percentage had only risen 16%. That's really really low.
I reached out to Choetech customer service and they sent me a replacement unit citing the original unit as faulty. It shipped directly from China and took a few weeks. Comparing the two chargers side by side it's clear they've been making small changes to the text on the unit, font size/weight, as well as changing the stated power output from the fast charge ports. At the end of the day it doesn't matter though.
So I tried to be fairly rigorous in my testing and tracked battery percentage over time as well as charge rate over time. A real QC 2.0 charger will hit a charge delta of 80% per hour during bulk charging and taper off as the battery nears full capacity. The Choetech charger comes in at a measly 10% per hour. I put it on at 40% battery and it took all night to get to 100%. You can see from the graph that the charger behavior is to switch on an off instead of providing a clean source of power.
I've attached the same graph (same phone, battery, cable, etc.) with the same axes and time scale but hooked up to a standard charger (non QC 2.0) and it hits a 50% charge rate easily before tapering off. I've verified across two units and two different devices that the Choetech charger is a complete sham when it comes to meeting its advertised specs. I ended up returning my original unit to Amazon and the 2nd unit to the seller in New Jersey.
Reading through the reviews on Amazon, either they're shill reviews or they're from people who haven't actually taken a hard look at what the charger is doing. I'll admit, it does seem to "charge" your devices, but at a snails pace.

I bought one of these units recently. Mainly to charge my non QC2 device.
I thought I'd get one, for when I get the Note 4 or S6.
Anyway, I returned it, it charged slower than my original plugs.
Hopefully another company will release a multi port charger with QC2 soon.

I'm waiting for these to become available. The 3 and 5 port models look enticing.

Yes, number 3 and 5 is what I'd be interested in too.
Hopefully Amazon UK or similar will stock them.
Thanks for posting.

Tronsmart dual USB 36W Rapid Charger (QC2.0) Review

After a 54W Desktop Charger a few weeks back, this is my second review unit from Tronsmart. It's been 6 days since I'm using this product and I'm definitely inclined towards writing another great review on their product.
Before I start with the review, here's the product listing on Amazon
Like most of my reviews, I'll split this up in following categories:-
1. Packaging & Content
2. Build Quality & Design
3. Functionality
4. Pros & Cons
I'll go through each of them, one at a time.
Packaging & Content
The Tronsmart Rapid Car charger came well packed in a colorful display box with every detail written all over it. Unlike last time, this box isn't one of those recyclable brown boxes but this one do give an impression of a renowned brand too. And there's seal on the box (It's kind of important to me).

"lightbox_new_window": "New window",

}
Following are the in-box items you get:-
- Tronsmart Rapid Charger ( 2 x USB Output )
- 2 x USB Cables (premium quality)
- User Manual
- VoltIQ Info Card
Even if it makes sense to give 2 USB cables since the Rapid Charger has 2 USB Outputs, honestly, I didn't expect that. And both the cables are premium built and long enough to use confortably even while charging (unless you have cigerette lighter port located somewhere far away from the dashboard). Infact, as per Tronsmart, the USB cables are custom made standardized 20AWG cables (thick cable for less voltage drop and strength) specifically designed for Quick Charge 2.0 Ports.
Moving on to the next category...
Build Quality & Design
I'm very picky when it comes to design & build and let me say this outloud, so far, Tronsmart hasn't dissapointed me at all. The rapid charger's quality feels top notch and I couldn't find any flaw in the finishing of the product either. With it's matte black surface, green colored USB Ports and engraved brand name, the charger looks absolutely gorgious. Look at the images and decide for yourselves:-
Overall, this is a beautiful charger which is small (for a 2-Port charger), very light and yet feels very sturdy in hand.
Functionality
Inspite of it's small size, this rapid charger packs 2 USB Outputs with both having Qualcomm Quick Charge 2.0 Certification. In other words, it's a tiny powerhouse which can charge 2 of your power hungry USB devices rapidly and simultanously. The specification on Amazon listing claims that this charger can charge 2 QC2 devices simultanously at 9V/2A (max) and for non QC devices 5V/2.4A (max). With that said, one must know that a phone incapable of handling such high power (mostly old phones) might be adversely affected due to high current/voltage flow. And that's where VoltIQ comes into play.
The VoltIQ
The voltIQ is a smart circuit that controls the flow of current and voltage by identifying the connected device and it's maximum supported power input. For example, a 3 years old Nexus 4 doesn't support rapid charging and it could draw only upto 5V/1.25A (avg) max power. Even, the genuine adapter that came with it had rated output of 5V/1.2A. So what happens if I connect it to Tronsmart Rapid Car Charger ? No, it certainly doesn't damage the battery of nexus 4 thanks to VoltIQ which detects that the device can draw only upto 5V/1.2A and delivers the same power for efficient charging. Similarly, when a rapid charging capable device is connected, the charger delivers an optimum fast charging output to charge that device at a much faster rate.
To validate the claims made by VoltIQ, I tested the review unit with an iPhone 6 Plus, S6 Edge+, ZenWatch and Bluebux X. Following are the results of the OEM charger output and Tronsmart Rapid Car Charger:-
Although I'm more than satisfied with the performance of this tiny charger, there's one thing that I'm not fully convinced about. The Amazon description of the product says this adapter would deliver upto 5V/2.4A for Apple products, however, my iPhone could only draw 5.12V/1.15A which is significantly lesser than the power advertised. But then again, the description could have been for an iPad since I know the iPad comes with a higher power rated adapter compared to an iPhone. I'm just going to ignore this because my iPhone is charging faster than it's original adapter(Yes, iPhone 6 Plus supports fast charging via iPad's adapter).
Update [9/19/2015]: Just heard back from Tronsmart. Here's what they said on charging Apple products:-
Because VoltIQ technology will automatically detect the demanding current for the devices needed. For the iPhone 6 with empty battery capacity, Tronsmart charger will offer the largest currect 1.5A, for iPhone 6 Plus, the largest current offered is 1.8A, and for iPad, the largest current is 2.4A. So in the description it says this adapter would deliver upto 5V/2.4A for Apple products.
When I was charging the iPhone 6 Plus, the current drawn initially was 1.25A (at 90% battery charged) and finally settled for 1.15A (at 93% charged) few minutes later. So the explanation do make sense. As I suspected earlier, only the iPad utilizes the full potential of this charger but either way, the iPhone 6 Plus charges way faster than it's original adapter and it's battery is definitely not affected since it supports fast charging (high current input) - source
Overall, if you're looking for an affordable car charger, this is the way to go. And if 2 ports aren't enough to juice up all of your devices while you travel, you can look into several other Tronsmart Accessories which offer upto 4 USB Outputs on a Car Charger.

"Cheap" USB A to USB C Cables to work with your old chargers

I was asked in another thread for this link so I thought I'd share here for others since I'm sure we're all in the same boat here.
So like you, I have a billion USB-A cables and chargers around my house, work, friends', and the car. Since we're moving to USB-C connections, that means none of those will work. There's another thread in this forum that discusses an adapter, and that might be the best solution for you. But for me, I decided I just wanted to buy a handful of cheap cables that should work well enough until we have some good options that don't cost a ton of money.
With that mindset, I went looking and checked all of the usual places - Amazon, eBay, Monoprice, etc. While I did find some cheaper options, they all came with the haze of absolutely no idea if they would work well or not. However, I did find a 4-pack on Amazon for $20 of USB-A 2.0 male -> USB-C male cables (i.e. what you need to plug into your chargers you have all over the place yet while working with your new Nexus).
http://www.amazon.com/gp/product/B013RMG5WY
I have no clue if these are good cables but they at least have 30 reviews with a 4.6/5.0 rating. That was enough for me to buy. Once I get my N6p in, I'll test them and compare them against what ships with the phone and let you all know how well they work. Until then, your guess is as good as mine but this was the best option I could find at this time.
Hopefully this is useful to somebody else until Anker, Choetech, or somebody else comes out with some higher quality cables at a low price!

Wow, and multiple colors for that price too?
I'm sold, I was looking too but you did the final research for me. Thanks Jax!

This is tempting, I've been thinking about getting those for a few days now

Same price, all black http://www.ebay.com/itm/321859807320

Thanks for posting that. I saw those too but will wait in the hopes of finding 6 foot ones for around the same price. If anyone sees those, please post.

May be a dumb question but can this use the full potential of a 3A charger or would you need USB C at both ends?

there are several sellers on Aliexpress with cables around $2

I bought that 4 pack on amazon a few days ago and it's being shipped from the UK

FYI on that amazon link, the affiliate is probably not in the USA, based on this time on their detail page:
Continental US Street ETA 18 - 26 business days
I hate falling for this, but just wanted to point that out. But you'll probably get the cables before your shiny new 6P, so there's that! :good::good:

One plus makes nice cables if you want a flat one. I have a micro USB one that I use for traveling and its great. I might buy some of their cables if I can find them for a good price.

I was also browsing and found that Anker makes USB 3.0 to type-C cables, does that have any benefit for backups and data exchange between the phone and a computer?

Found this one on amazon for $5.45 with free prime shipping:
http://www.amazon.com/gp/product/B014J8QQT2

I believe it has to be type-c on both ends to get 3 amp charging. I think you can only get 2/3 charge rate max from a standard 4 pin cable.

@NCguy Nah it just has to be thick enough and rated for that much current

Could not for the life of me login through Chrome, had to use safari...
Anyway thoughts on this?
http://www.banggood.com/Wholesale-Cables-c-2894.html

I plan on phasing out my micro USB cables eventually, but in the meantime I figure the one that comes with it, plus 2 of these will get me by for now. Picture is a link to Amazon, $8 for two!

Those would be the same as these
Except for free shipping with no minimal order.
Just one thought. Are you sure it'd be just a matter of rating?
No "negotiation" involved between phone and charger before the phone would draw the current?
My guess would be that without "negotiation" the phone will only draw 2.1Amps (or less) tops.

And when I say "negotiation" I mean one of:
- Some kind of ID pins (which give out charger capacity) - like VGA id pins
- One or more shorted pins on the C plug to indicate current capabilty - like Asus uses, shorting a pin at the chargers USB3 plug making it give out 12v instead of 5v
- Any other other kind
Or it just uses several C plug wires for + and other as much for - and that's it.
I've seen that, even for USB2,type micro-B, different chargers make different things to the usb data pins, for instance (grounding, pulling-up) effectively with different outcome on outgoing current.
Cables that only have 2 wires will give out a different behaviour than those with 4 wires on these chargers.
For instance "charging on AC" vs "charging on USB" showing on battery monitor (or looking at the kernel values in /proc)
I have a "China Charger" with 2 outlets "for SAM" and "for IPAD" with very different results depending on the cable and device I connect there.
And I know both will output up to 2.1A (or perhaps even more), that's for sure.
My old SamSung DUOS would only charge if the charger "wasn't able" to provide more than 1Amp, for instance. Had another dual car-charger and would plug it to one of the outlets and nothing. As soon as I plugged something into the other (limiting the max current available) it'd start charging.
So there's a lot to it to be cleared on USB charging.
Anybody with some bright know-how?

The best thing about the One Plus cables are that the Type-A end is reversible too! They're a little more expensive than some of the other cables listed in this thread, but that convenience alone made it worthwhile to me.

The only downside is that they are limited to 2.4A but I'll manage with that as a backup. I need to stock up on cables so I'm buying a variety of them including the OP ones I've already ordered.

Type A to Type C High Amp Charging

After tons of consternation, I'm starting to feel a little better about charging the Nexus 6P. The Android Life Post, unscientific as it might be, clearly shows that the Type C phone is not dropping to legacy USB power profiles. In addtion, the Type A to Type C cable on Google's Store site carries this footnote:
¹Charge rate will vary depending on the capabilities of the legacy USB port.
Read "legacy" as Type A. This clearly intimates that the charge rate will vary based on the output of the USB port. Hence a 2.4Ap charger will charge up to 2.4A and not 0.5A or 0.9A which are legacy rates. Hence, it is possible to run 3A from Type A to Type C given he appropriate charger and cable. But even 2.4A isn't bad.

2.4 yes, but not 3A, the 3A is only obtained from the extra pins in the type c connector. I don't think it will be that big a deal. I don't know about everyone else, but not every single charger I have has to be a quick charge. I will get one or two for the house, and one for the car. The rest can be legacy plugs. Also, don't forget that the quality of the cable matters a lot. You will find some cables only charge at .5A

You can provide 3A though Type A. The number of pins is not the limitation at this level of charging..

Absolutely. People keep confusing the power specification and control with what the wires and connectors will actually do. As long as Google did not enforce the power specifications such that when the phone can not communicate with the charger it drops to legacy, then it is possible to pump 3A through to it. A few manufacturers have made 5V/3A charger for tablets in the past. I recall my friends transformer charger came with a warning label not to use it for anything but the tablet.
Here is an Asus Charger for the Transformer (TF100) which is a captive wall charger at 5V/3A using micro B.

You can provide 3A though Type A. The number of pins is not the limitation at this level of charging..

Yes, you guys are right, although I am pretty sure no one has a USB type C to type A cable that will do 5V/3A yet, right?

The one on Google's store specifically states it can do 3A at 5V. As I'm sure the one that comes with the phone likely will be able to (even though its from Huawei, not Google).

The one that comes in the box is a stubby one, so not sure it will allow the full capacity.

They do actually:

But it's hard to find and generally expensive.
(Edit: more are showing up/ i'm finding more: http://www.amazon.com/dp/B016PDLA68?psc=1)
And as has been mentioned, Google lists one yet to be released, in their store.
Also USB A wall chargers putting out 3A are rare outside of Quick Charge 2.0 Class A, which likely won't work properly without the 810 chip telling the brick what it wants. But as Quick Charge is not yet enabled (yes it can be switched on), but the 6P meets a quick charge standard, my theory is that Google is pushing Qualcomm to certify for USB A to C quick charge (3.0?). As far as I'm aware ( I might be wrong), there are no USB C phones out yet that support Quick Charge yet? Could be the first. Who knows.
