Charging Nexus 7 - travel charger

Hi all,
Can I please get some advice from someone who might know better than me. I have been using the following charger on my travels to charge an iPad and Samsung galaxy nexus at the same time:
http://www.amazon.co.uk/Skross-Char...?s=electronics&ie=UTF8&qid=1342643375&sr=1-23
I've just plugged my nexus 7 in on its own and I get nothing.
I didn't think the nexus would need a higher amp than the iPad? The Asus plug that's charging the nexus says its 2amp and the travel charger says its 6.5amp. Am I being amazingly blind or stupid here?
And if I need a new travel charger for my trips into Europe can I have some advice on what to buy before I buy something else useless.
Thanks all!

Nexus 7 trouble with other chargers
I see the same issue.
The Nexus 7 charger lists: Output 5.0V===2.0A, Nexus 7 will charge.
iPad 2's charger shows: Output 5.1V===2.1A;Max 10Watt, Nexus 7 will not charge,
Philips universal charger: Output 5V===2A; Max 10Watt, Nexus 7 will not charge.
Blackberry phone charger Output 5V===500mA, Nexus 7 will not charge.
Blackberry phone charger Output 5V===700mA, Nexus 7 will charge.

To answer the OP: The Amazon product page clearly states Output 5.0 VDC / 1000 mA max. N7 needs 2000 mA (2A). Derping in public again. Don't mind me. :silly:
To add to the list:
Samsung Galaxy Tab 2 7.0 Charger: Output 5V ⎓ 2A; Max 10Watt, Nexus 7 will charge.
XtremeMac IPU-IH2-11: Output 5V ⎓ 4.2A (2.1A per port); Max 20Watt, Nexus 7 will not charge. (Galaxy Tab 2 7.0 charges though.)
The N7 seems very picky about chargers, unfortunately. My XtremeMac is now powering my charge cables for my wireless mouse and keyboard, freeing up 2 USB ports, so not all is lost I guess.

I have a 2.1a car charger, but it doesn't charge it.
http://www.amazon.com/gp/product/B007TV88F2/ref=oh_details_o00_s00_i00
EDIT: Interesting. It will not work on the car charger wiht my "charging only cable" which has shorted out datapins to register as an AC source. But, it does charge on a normal USB cable.

I have a tf201 charger (here i refer to the usb block, not the cable) that seems to super charge the nexus 7, that is to say, very fast. The tf201 charger is 18 watts. Also, I have noticed my usb 2.0 ports on my desktop will not charge the n7, but my usb 3.0 ports will.

I started a related thread asking if anyone has examined the proprietary aspects of the charger here:
http://forum.xda-developers.com/showthread.php?t=1780211
Basically, we should be able to build (or eventually buy) some type of adapter to enable proper charging with any 2A charger after we figure out exactly what the charger is doing. I wouldn't be surprised if all Asus tablet chargers already worked properly without an adapter.

This answer is clouding up a lot of legitimate discussions. The current rating doesn't matter to this conversation at all. If the current is above 0 the device should show the charging icon. If not, there is some other problem.

You are correct that my remark about the OP's charger's current was not a valid point. I have stricken it from the record.
That said, some serious weirdness is going on with the N7 regardless. On the XtremeMac charger the N7 will charge. But incredibly slowly, and the battery status reads as discharging, even though the line on the battery graph is rising. I don't even know where to begin in trying to explain that.

Agreed. I bought a pair of dual 2A chargers and neither of them will charge it at all (no charging icon). I tried shorting the data lines and still nothing. The dual charger that came with my Razr will charge it slowly (about 16 hours from 0 to 100%). My old 700ma Blackberry charger works just better than anything other than the OEM charger. Frustrating and I don't want to keep ordering different chargers with my fingers crossed.

I don't know what a XtremeMac charger is, but I'm assuming it's for charging an iphone or ipad or something? the Nexus 7 and the apple products don't share the same charger design, so the Nexus is probably only drawing 500mA while charging from it.

You can also add the MonoPrice 8856 charger to the list that do not work with Nexus 7

Mine is charging with Galaxy Nexus 5.0v 1.0A charger.

I have two chargers that work.
1: Nokia 1.2a fast charger
2: Blackberry 1.8a charger
both have integrated charging cables, which are 6ft in length.

The Asus transformer prime which is a USB charger with proprietary cord also has something weird. Other USB chargers with the same power specs connected with the Asus USB cable won't charge the prime. Or they charge where it literally takes like 24 hours to reach 100 percent.
There's something different in that Asus power plug on both devices it seems.

I'm not sure what It's output is but the standard Verizon branded micro usb charger does a great job charging my N7. I think they for sell around $30 in the VZW stores tho.

The 1.0a charger that came with my LG Revo works great, almost as fast stock. I bought 2 extra of that charger on amazon about 9months ago for under 10 for the pair.
Also the charger for my old Droid (.7a iirc) works as well, but it's slow as hell with the screen off, and barely keeps up with just web surfing.

The Charger with the HTC Desire seems to be charging - though slowly as its a 1A charger.

Does anyone know whether the International Samsung Galaxy S II charger works?

The TF101 charger works great, and fast too - about 1% a minute.

My Samsung SG2 (i777) charger seems to work with the N7

Aukey Quick Charge 2.0

Hi! I bought a wall charger from Aukey that allow to charge up to 3 devices at the same time, what is great since I'll be able to charge the phone and the tablet at the same time! According to the manufacturer the charger is able to adapt the output to the needs of the devices! So my question is, can I use this charger to charge the GWR without damage the watch, since the output of the original charger is only 0.85A!

I think it should be fine. I have used my charger a couple of times without issue for my GWR and now my Huawei

I've been using an Aukey quick charger for a month now and no problems whatsoever. Normal charging times obviously (blisteringly fast on S6 however)

So I don't need to hurry about the output current, or in other words, get the watch too much warm and reducing the battery life?

It is completely fine. The charging circuits of these devices (watches, phones, tablets etc) takes only what it is allowed by the limitations set to the charging IC circuit when supplied with 5v power over USB. I have an USB amp meter and the GWR barely uses half of the original chargers 0.85a capability. I've used my OnePlus One charger (a high quality 2A charger) to charge my watch as well occasionally, which also charges my Nexus 7 2013 regularly and that never takes more than 1A~ from this as well.

I've been using a Aukey Charger for a couple of months and no problem so far. The current regulation is supposed to be made by the device, not by the charger anyway ...
For those who wonder, I also checked if our G Watch R has QC 2.0, but it doesn't. It still charges at 5V on a QC 2.0 slot.

Need a charger capable of rapid charging

Just bought a Nexus 5x off Swappa and it didn't come with the original LG charger, just a USB C to A cable. Are there any 3rd party charging blocks and cables that work well and provide rapid charging for the 5x? I've looked at a lot on Amazon and Ebay and there don't seem to be any that work as well.
There's this from SONEic....
Also, can anyone tell me if you'll get faster charging (like Type C to Type C) if you use a USB 3.0 to Type C cable, or does it matter?
Thanks,
Jank.

This CHOETECH power supply works well: link
You need a type-C to type-C cable to take advantage of the full speeds. I use this one: link

Check out this sheet for chargers, for cables and accessories.
https://docs.google.com/spreadsheets/d/1wJwqv3rTNmORXz-XJsQaXK1dl8I91V4-eP_sfNVNzbA/htmlview
Also Google"Benson Leung". He's put a lot of time into testing a lot of products and can probably save you a lot of headaches. There's a lot of really questionable cables and chargers out there for USB type-c so you want to be careful. It's not like the old micro USB days where anything worked. Bad cables can burn your phone, charger or worse

@adobeman - appreciate the reply. I have seen that spreadsheet but noticed nothing had a review date for this year, 2016. I had hoped something more current that was a sure winner would have been released by now. Maybe not, maybe it's just the SONEic and Choetec so far. There are a ton of the LG OEM cables/chargers on eBay but they all ship from China so are questionable at best, don't know if they're knockoffs or real. Oh well. The problem with the Google cable on the play store is that it's a single piece, the cable isn't removable.
Guess I'll give one of these other two options a shot and go from there. Thanks again!

I have tested LG OEM cable/charge on Nexus 5X, the charger support Quick Charge, it works well with device but it didn't charge as quickly as stock Nexus charger. I remember that it took me about ~1.8 hours to charge from 20% to 100% with LG OEM charger. LG OEM Charger output is 5V/1.8A, 9V/1.8A while stock one is 5V/3A.
If you want to take full advantage of Nexus 5X fast charge, you should choose charger that can output 5V/3A current. You can get more information in this article.

@SuperBoUDS - thanks. I went with this option this morning: SONEic USB Type C rapid charger & this Anker USB C to USB 3.0 for another cable. They should be here Friday and I'll review and confirm how well they work. CUrrently, I only have a legacy USB 2.0 to Type C cable that came with my used phone. It only charges up to about 1400 mA when the batter is really low.

FYI, since the spreadsheet is outdated as of 2016 the best (albeit disorganized) source for USB-C cables/charger/accessories that are compliant is probably benson leungs amazon profile feed:
https://www.amazon.com/gp/cdp/member-reviews/A25GROL6KJV3QG/

if you don't want to go with choetech or tronsmart, you can find oem LG chargers and cables on eBay for $15-$20

I have three choetech USB C wall chargers. I've had inconsistent performance with them -- at times the phone does not register it as a rapid charger, and so far one has stopped working completely. The USB cables are from Anker and I haven't faced any problems with them.
You can't go wrong buying an OEM or Google made charger.

I use this one while traveling. Benson Leung approved. It works great and also allows to charge another USB A device at same time. https://www.amazon.com/Charger-GMYLE-Adapter-Macbook-Chromebook/dp/B01193T77I

After using the SONEic USB C to C charger I purchased above, I can say that I've rarely, if ever, seen it charge faster than 2.15 mA. That with the battery fairly low so I would think it should be charging faster. It does come up as rapidly charging though. It works well enough, just was hoping for more.

I can confirm that the Soneic didn't go above 2A using Ampere app . I tried the Choetech and it went upto 2.5 A once.
Both say charging rapidly. I'll be returning the Soneic
I've seen varying performances with all chargers, none of them seem to sustain the charging rate even if the phone is <10%
Not sure if it's the same behavior with the OEM charger

How about this one? Is good enough for 5x ,

Mi Mix Factory Charger/Type C USB Question/Issue

Hey guys,
A few weeks ago I made a thread about my Mi Mix NOT detecting on any PC despite trying different Type C usb cords and the factory one.
I've never really timed how long it takes to charge my phone and recently I downloaded this Ampere app that measures the voltage and mah.
My Mix was at 40% and I plugged it in and left it in for 20 min and checked the app. It said something like 3.7 voltage and charging at 120mah minimum and 190mah maximum.
From what I'm reading, thats really bad.
So I plugged my phone in with an Anker Type C usb and a charging block from an LG 5.
Phone was now charging at 1600mah ish.
I'm assuming there is an issue with either my charging equipment AND / OR the charging port of my Mix. I've already ordered a new charging port from aliexpress 3+ weeks ago because of my PC unrecognized issue.
Anyway I just want to confirm that getting 120mah- 190mah on the stock charger is NOT normal?
I've ordered this https://www.amazon.ca/AUKEY-Charger-Samsung-Qualcomm-Certified/dp/B00RJO6AHM
and another Anker Type C cord to replace.

I don't have it with me, but I think the original Chinese charger that comes with the Mix is a 2.5A/5V one.
I've never used it, don't trust the Chinese chargers, rather have used an original Xiaomi EU approved (CE marked) charger that came with a Redmi Note 4.
That charger is "only" 2.0A/5V, so you don't get any "fast charging". But the Mix will still get fully charged in max 3 hours, which is fine for me.
And I figure the battery will last longer, it gets quite hot when charging at higher rates.
I know because I tested on a Mi Note 2 which came with a 3.0A EU approved charger. That charger works fine, really fast, and I trust it from a safety point of view - much heavier and thicker than the Chinese one.
But I charge the Note 2 with the 2.0A charger also, to spare the battery.
Normal charging current is 1500mA and up, depending on the chargers capacity. It will be less towards the end of the charging cycle, when the battery is nearly full, and sometimes also in the beginning, for some reason.
Don't understand why, never figured that out.

well it sounds like my factory charger is messed. 190ma when it should be getting at least 1000ma. I hope that the Aukey charger I ordered is safe for it, I've done some reading with other xiaomi phone owners and they've purchased it but I haven't seen a Mi mix owner review it. It says its CE approved.

Aukey has a good reputation, but I prefer the Xiaomi original EU approved chargers, just because they are "Xiaomi". (and I am located in the EU, of course.)
There "might" be some sort of intelligent interface built in that especially suits the Xiaomi phones.
No particular reason to believe so, just color me superstitious.

i understand you. It is typically safer to always go with factory rather than aftermarket. But in my case, my phone is not charging correctly as I'm only seeing 190ma on the amp meter.:crying:

That can and does happen on certain custom ROMs and rapid charge doesn't kick in all the time. I can also say I had this issue on lg g5 and the charger proved to faulty on this occasion. So try the new port with old charger see how it goes. If no improvement try a different charger, the ones that come with the phone are very good. IMO

Question Slow charging

Hi!
I'm a bit annoyed about the charging speed of the Pixel 7.
Tested with a bunch of chargers and cables and charging is not going 15-16w.
Pixel 6 was charging with up to 21w with the same hardware.
Anyone having the situation?

The Pixel 7 does not charge very fast, yes. I got the original charger from the Google Store (for 30€) and it takes ca. 1,5h to charge the device from 5% to 100%. It won't get any faster I guess. Not every USB PD charger supports PPS, keep that in mind and buy only chargers that fully work for the Pixel 7.

All the chargers and cables I'm using are capable and we're charging the Pixel 6 up to 21W and the Pixel 7 is specified just like the Pixel 6 so i assume my one is kind of faulty

Understand that best practice is to:
1. Use low power charging
2. Charge up to 80%
3. Do not allow the batt to fall below 30%
This will help with battery durability.
Just my 2 cents.

Yes, but when you're on a bike packing trip in race mode you need a fast charging phone.
Beside that, I'm also pissed that devices don't fulfill their own specs
