Hi all, not sure if this is already well known in the community, but I thought I'd post it anyway in case someone doesn't know:
I've owned an OP3 for a few years and as such I've collected a few Dash-chargers. As most people who switch brands I now have a mix of cables, chargers etc. and I've been using them kind of agnostically, assuming that the only thing I'll ever lose is the "fast charging" capability.
Long story short, it turns out that both my Dash chargers will only charge my Samsung phone with "USB-speed" regardless of what cable is used. If I move the phone with the same cable over to an iPhone charger (the smaller ones), it AC charges like expected. This also works as expected with an old Asus android charger (with a OP3 USB-C cable).
So, if you have Dash chargers lying around and you assume they work just fine with other phones, you should verify if this is actually true by using an app like Ampere. What I've found is that they never go beyond USB charging, so they're more or less useless for anything but OP phones.
What's your experiences?
I don't think it's a good idea to charge other devices with your Dash Charger. I did that with my friends OP2 and the cable didn't Dash Charge my 3T anymore. Luckily I had a spare cable that came in with my Dash Car Charger.

Much to my amazement I discovered that the charger for my new Sony RX100 pocket camera also charges the Nexus 7!
I don't know about you, but the assortment of connections, adapters, power cables and chargers can be intimidating to keep straight.
Maybe there are others that would work too, but the accident of plugging in the wrong charger amazed me.
Nexus 7 just uses a standard microUSB cable so any cable from a modern device made by a company that isn't obsessed with proprietary chargers should work.
You're right on, I agree
Pawnty -
It's not that simple. While MicroUSB is indeed standard, not all cables will work on all devices. A friend of mine has a Nexus 7, and it is very picky about what cables and power sources it will charge from. I just got a Sony HX20V and am running into the same problem. It will not charge if I use the iGo AC charger that I have been using for my phones for the last 2 years, my retractable USB-MicroUSB cable, or my AT&T-branded car charger. So far, it has only charged with the cables that came with my Captivate and Galaxy Nexus, plugged into a computer or their corresponding AC adaptor.
I have this Griffin Dual USB PowerJolt Car Charger and its been working perfectly on all my devices, Playbook, Blackberry 9900, Samsung Galaxy S3, iPhone 3G, iPad 2 and many others but for some reason, this charger just don't want to work with my Nexus 7. I don't know why its so picky and wondering if you guys could help me identify the problem and preferably with a good working solution.
I tried opening it up and follow the advice from http://www.amazon.com/gp/customer-m...m_ciu_pdp_images_0?ie=UTF8&index=0&isremote=0. Both pins are already been soldered together but the Nexus still isn't charging!!
This makes me wonder where's the USB standard? How are some device / chargers so picky? What did the manufacturers do to prevent charging on other devices or charging through a non compatible charger?

You may get flamed for this question because chargers have been discussed a LOT in this particular forum. It seems that none of the discussions show up on the first page at the moment.

Thanks a lot. I did read up all the posting regarding the USB charging issue on the N7 but I still can't find the answers. I read about people having the Griffin PowerJolt and not able to charge their device.
After downloading the Battery Monitor Widget and plugging to my Griffin PowerJolt (short D+, D-), the device is charging (estimate: 384mA) but still not showing as charging. It shows Discharging and Unplugged. I don't think its the USB cable since the cable works on my PC.
So what causes this issue?

It doesn't matter why, just that your Griffin does not do a good job of charging. If you want more either buy oem or any charger designed to work with Samsung, those devices should work better.

I guess I still blame on the N7 for being so "picky" since the Griffin USB charger charges ALL devices, including iPad, Playbook, Samsung S3, iPhone and Blackberry but just not N7.

Yep, the Nexus 7 is picky. No question about it. But your chargert *does* charge your Nexus 7, the Nexus just doesn't indicate it's charging.
Personally, I bought two KMASHI chargers from Amazon. It's a 5V 2A charger and it works great. Charges at greater than 1Ah and the N7 indicates it's charging. Won't charge an iPad but it works for me. The one I bought is http://www.amazon.com/gp/product/B008XQYH1G but it shows as unavailable now. I suspect the other KMASHI chargers will work the same, though.

It charges it but its slow. Being rated at 1A, its can only charge at 300mA+ so its rather disappointing plus the charging isn't consistent. Sometimes when I plug in, it will charge, sometimes not so its another disappointment. But I guess I quickly adapt it and don't bother too much now.
I can still use my in car Head Unit with a build in USB port. At least I am getting 400mA+ and it shows as charging so I am ok

Ive been recommending this Sprint 2A dual usb charger to everyone. Its a OEM charger so you can expect a high quality product that works as it should and it puts out the required juice to rapidly charge the N7. It also has the added benefit of doubling as a wall charger. Ive had mines for about a week so I can confirm it does indeed work! http://www.ebay.com/itm/130712043019?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_1459wt_1399
Hey All.. I looked forever to find a solution. The Targus 2A car charger has a small (3") adapter cable that comes with it purportedly for Galaxy Tab. That little cable with the data wires shorted on the device end allows the N7 to be charged from ANY 2A car charger. I'm using the adapter with a Scosche dual 2.1 Amp Car Charger

Edit: I just built a usb cable with the data wires shorted on the Nexus end (cut, strip, short micro usb end green and white, remake connections red to red and black to black, insulate splices individually, wrap all in electrical tape or heat shrink for strength and beauty) and it works with all chargers. Took about 20 minutes.
Hello, Long time follower, first time poster.
I cannot post the link, but if you search "Juiced Systems 4.2 AMP" in ebay it's the first item under "Best match" and it's $19.99
Has anyone tried these chargers that claim 2.1A per USB port? Or does anyone know of any similar car chargers that charge 2 devices @ 2.1A?
I just want to buy the best charger that isn't going to blow up my phone, and a dual charger would be excellent if possible.
Thanks in advance.

If it's the same one here from amazon http://www.amazon.com/Juiced-System...dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 it appears to be apple only.
The one Android customer from that Amazon link said:
I bought this assuming it would charge my Droid DNA at an AC rate. Unfortunately, it charged at a USB rate and could not keep up with usage while driving.
It sounds like with that particular device, in order to get an Android phone to charge at an AC rate is to either modify the charger (through soldering) to short out the data pins or use a USB charge-only cable (DIY modification of an existing cable or purchased one). The Android phone should then see the charger as AC instead of USB for, hopefully, full and faster rate of charge.
I know you are looking for dual port, each with 2.1A - but I wouldn't hold my breath this one will output dual 2.1A without throttling down one of the ports. Its impossible to fit quality circuit in a small cigarette lighter package where due to excess heat the efficiency of your converter will decrease. And even if they manage to produce 4.2A you will either blow your fuse or melt your charger. Just think about it, you won't have any air circulation to even cool it down.
I only trust dual port chargers with 2.1A/1A rating. I reviewed one before - HERE from iSmooth which does work! Also, to my surprise, iSmooth charger was actually made for iPad/iPhone but it WORKS perfectly with Note 2. I can't voucher for other Apple converters, and as a matter of fact I have another one with a separate Apple and Android ports and Note 2 doesn't charge from Apple port. But the one from iSmooth I'm using right now works perfectly for Note 2 and also looks awesome in the car with a blue glow light
I have a few of the belkin/off brand dual USB auto adapters. But they all have output of around 500mA so basically when using bluetooth and GPS on the rd I'm drawing more power than I'm getting. I've looked around on amazon for some usb adapters but seems like a lot of them for some reason only really fast charge with IPads or other apple devices and for some reason they slow charge android devices. Apparently iphones have some sort of communications with the chargers to draw more power.
So my question is does anyone have one or know of one that works with the G2 and fast charges. I'd prefer one that is flush like my existing belkin and not one that sticks out a few inches. Dual ports would be nice, but at this point I'm not picky. Having said that, I'd like to not spend $30 on it.
To add to it, I installed some battery monitor widget and while in the car today I just popped it open and noticed that it said "USB Connected Discharging" So basically It actually drains power quicker than if it wasn't connected to the charger at all!

There is a long thread on this already.

It seems that the bigger issue is not finding a 2amp charger, but a USB cable with the correct gauge similar to the oem one. I believe the oem cable is 20 gauge and I believe I found one on Amazon.

I don't get why it's such a difficult thing to find? Doesn't LG make a car charger that charges it's own phone?
I use my older Motorola ones and they work fine. Not full 2 amp but I can stream iheartradio or Pandora and the phone will charge up still. But the screen is off, not like using GPS. Still would like a fast charger tho.
I have an Anker 24w 2 port charger and it charges my phone as fast as the wall charger. I tested it with a charger doctor and it does read 1.8a current flowing thru.

It's not the charger that seems to be the problem. 2a Chargers can be had in many places. It seems a 20 gauge wire is the difference.
Here is a link to a post I made in another thread with a tested and working setup in my car
Cheap too.

No, the problem is the op isn't using a charger designed for Android.
Has anyone had issues using Anker PowerIQ chargers with the Nexus 5X? I've purchased an Anker 2nd Gen Astro E4 13000mAh 2-Port (3A Output) and when connected to the Nexus 5X it keeps connecting and disconnecting. It does not appear to be a cable issue (my old 2A charger works fine through the same cable). Meanwhile the Anker charges the old Nexus 5 without any issue - it's just the Nexus 5X that seems to experience problems.
I'm wondering whether it's Anker's PowerIQ having trouble working out the correct power draw for the Nexus 5X. If anyone's had similar issues with PowerIQ or other chargers, I'd love to hear potential fixes or confirmation that I'll need to switch it out for something else.
I have encountered the exact same issue with the Anker Astro E4 battery. At first I figured it was the cheap Aliexpress USB-A to C cable I was using, but I think you're onto something about the PowerIQ not knowing how to negotiate with the 5X correctly. I contacted Anker Support on Twitter yesterday and was told to contact [email protected] about the issue. I haven't yet pursued that avenue, but I'll update once I have.
I don't think I have any issue with my PowerIQ non-quick charging 6 port desktop charger or 2-port battery park (15600 mah)
I have the same issue with my Nexus 5X. After I posted a negative review due to this on Amazon, Anker reached out to me and has shipped one of their 4 port chargers which they think will resolve the issue. We shall see...
It still could be a cable issue. The difference is that your Anker may contain smarter charging tech inside and it is self regulating what the cable is asking for (possibly 3A) when it cant really deliver that. With your other charger, it is possible it is blindly delivering an overcharge for its rated max and may brown out soon if not over time.

In my case, I'm 99% certain it's not the cable, as I'm using an OEM / Google A->C cable.

I honestly don't know, as I don't have an OEM type A wall charger to test it with. I would assume so, since it came from Google. I did receive Anker's 4 port car charger last night, but need to wait until this evening commute (once my battery drains) to see whether it works. Plugging it in this morning showed just "charging" when I was at 98%, but it wasn't cutting in and out like the 2 port one was.

My OEM cable is on its way as well. If you get a chance to test it on a different charger later on, please post the results. I would love to see that OEM cable say "charging rapidly."
Followup: I tested the Anker 4 port charger with the OEM Google A->C cable, and it does register as "charging rapidly." Using Ampere, I measured 1340 mA / 4.08 V peak to it. I also tested my new Tronsmart charger (with built-in USB C cable), which measured 1710 mA / 3.903 V peak.
I have same disconnect issues with aukey quickcharge battery pack
After a little back and forth with Anker email support, they are sending me an Anker PowerCore+ 10050 USB-C Battery Pack as a replacement for the Astro E2 not charging the 5x correctly - at no charge! Very impressed. It's been shipped but I haven't received it yet - from what I can tell spec-wise it has native USB Type C and A ports, but I can't yet confirm if this can fast charge the 5x at the same output as the stock wall charger.
I'll report back once I've had time to test.
sounds like an combo issue of the cable and battery pack/charger.
have you guys seen the thread about a google engineer (benson leung) reviewing usb -c cables?
basically usb-c standard cables should have a resistor in them which the phone uses to detect if the charger is able to supply 3A or not. without this (most cables seem to not have this, including the oneplus one) the phone thinks it can draw 3A and tries to do so. this can result in damaging you charger as that is more than it can produce. but apparently it can also damage components in your phone as the current it thinks it is receiving is higher than the actual current being received.
The disconnection issue sounds like the charger has a protection mechanism and realizes the phone is trying to draw more power than it can provide, so it cuts off to prevent overloading.
I tried the PowerDrive 2 and it has the same isse where it charges for a few seconds, stops, then charges for a few seconds, etc. I emailed thier support but have not heard back.
I have the same issue with Aukey PA-12, tried two different cables. The charger works fine with my wife's quick charging phone.... I hope it is a kernel issue that can be fixed. The original Google charger works flawlessly.
