Hello everybody,
I will soon get my Nexus 7 and want use it as a GPS. Now I am trying something really difficult in the World of iDevices still not having the standards applied.
I am searching for a dual USB charger cappable of fully charging (not just usb mode, but AC) both the Nexus 7 and my One X at the same time.
So it would need a 2.1A Output matching the Nexus 7 and a 1A for the One X...
All I found was some chargers mostly designed for iPad's and other iDevices...
Please help me if you know more than me
Thanks for your advices !! :fingers-crossed:

Car Charger and Cable from Deal Extreme 146751 Doesn't work in faster charging "AC" mode.
So after having owned the Toshiba Thrive and now am using the Samsung Note 10.1, I have to say I'm disappointed at how slowly the Note 10.1 charges... Even after leaving the Note plugged in to the stock Samsung 5V 2A charger while using it, I can discharge it faster than it can charge (mostly playing games), which is sourly disappointing.
I saw a singular 5V 3A charger on Ebay, but it was for a car... not to mention no telling if it was legit.
So does anyone have any suggestions on a better charger?

There isn't one- there's two charging modes- "high-power" and "USB", and the rates are set by the hardware (with help from the kernel software) so getting a 3A supply won't charge it any faster.

I believe the Toshiba Thrive has a 10.8 volt 2030 mah battery and the charger puts out 19 volts........ so it should charge a lot faster.
The 5v 3a chargers generally are a 2 port charger and one port usually puts out 2a and the second only 1a.
.
It seems the chargers are a little bit different for this model. I had the 2012 N7 and tried like 5 different cables and cahrgers before I settled on the PowerGen Dual USB 3.1A 15w High Output Car Charger from Amazon.
However... I looked at the back of the Ac Adapter with my 2nd gen and its specs are input: 100-240v .25A 50/60hz / output: 5.2v ~ 1.35A
I think the 2012 N7 was Input: 100-240V, 0.3A / Output: 5.0V/2A,10W
What difference will that make in getting some extra chargers...?
I haven't tested my 2nd gen in the PowerGen Dual USB 3.1A 15w cus I don't want to fry it.
The device will only take what it needs, current wise.
If the voltage is 5V, then anything 1.35A or above at 5V should be no problem.
Is there a dual port car charger that would work for the Nexus 7 and my Samsung S4 for them both to be on the charger at the same time?

Do you charge both items at the same time while they are operating?
Do you use the standard USB cable for the device in this unit?
I want to use the Nexus 7 GPS and get the signal from my Galaxy s4, so both will be running and need to be on charge most of the time together. Will this work?
My question is would using a 2.1 amp wall charger over the stock charger pose any danger of damaging my Flo?

My stock charger is still unwrapped.
I'm using a 2A charger for all my tabs (Nook HD+, Nook Touch, old & new N7s).

The charger spec just lists the max output. The tablet is the one that decides how much current to pull. So it is safe to use the 2 amp charger.
How fast will it charge with an 2,1 amp charger ?

At this point, I don't think it has been determined. Install a battery monitor to see if it draws more current with a 2a supply over the stock 1.3a.
I am living in Germany so I don't have a Nexus 7 yet. But the charger of my mobile phone is broken and I would buy the 2amp charger, if it charges faster because I can use it with my Nexus 7, too.

There is something to be aware of when buying a 2a supply. The original Nexus 7 required the data pins (2 and 3) of the charger to be shorted in order to draw full current (don't know if the new one behaves similarly).
The majority of usb chargers out there are designed with Apple products in mind, which shunt a resistive load across these pins to tell the device how much current is available. The result of using the original Nexus 7 with these chargers is that the device only draws about an amp.
My experience has been that HTC chargers have the correct pins shorted, while Monoprice's do not. Your on your own with any other brands. You'd need to measure those pins with an Ohm meter to be sure.
Hi
Didn't think of this before I bought it.. But I've just received a QI charger from Amazon.
Which charger do I used with it?
The one from my nexus 5 or the one from the nexus 7 2013?
Ideally I want to be able to charge either device.
The QI states 5v 1500ma input.
Also what's the best app to monitor the charging, time, input heat etc?
Thanks

I can't say for what apps to monitor times etc... But
Did your qi charger not come with a mains power adapter.
I can't say for the nexus 7 but the nexus 5 comes with a 5v 1200ma charger so it won't be able to supply the current that your qi pad needs.
Have a look on your nexus 7 power brick. It will tell you what it outputs.
Nexus 5
Input : 100-240V
50/60hz 0.2A
Output : 5.0V 1.2A

what brand? you can try plugging it in your laptop. mine (Nillkin) says Input: 5V/2A but it still works just fine if i plug it in the laptop.
otherwise I use the Nexus 5 charger. I think it's just the maximum your charger can handle.
You can use any USB power source... What varies is charge rate. I picked up a 2amp supply from amazon. You have to figure in less than 70% efficiency... Especially taking into account non laboratory ideal conditions and manufacturing...
1 amp input will be like slow charging from a computer at best. 2 amp will be on par with regular wall charging if not better. You always want an adapter that is above what the charger can handle to make full use of the charger... Lower ones will still let it work to lesser and lesser degrees till it doesn't charge the device depending on supply and device needs

It can be used with either the Nexus 5 or Nexus 7 AC Adapters. The Nexus 5 is 1.2A and the Nexus 7 (2013) is 1.35A I believe. Neither will fully power the Qi charger, but it will still be enough to make it work. The charging time for your phone will just be longer since the Qi charger is not being provided full power, so the current the Qi charger can provide to the phone will also be lower. If you want your Qi charger to operate at full efficiency/power, try to use an AC adapter that is 1.5A or higher.
Since your Qi charger only requires 1.5A, the Nexus 7 AC adapter is the closest, so I would recommend using that one.
In the future though, you might want to consider buying a higher output AC adapter:
The Blackberry Folding Blade Charger is 1.8A output, and microUSB, so you can plug it directly into your Qi charger (or phone if you ever need to charge you phone at rocket speed!):

The Boxwave Fast microUSB charger provides 2A output, microUSB as well, so if you ever buy another Qi charger it would be good, as many Qi chargers require 2A input.

You could also just buy an adapter similar to the Nexus 5/7 without the cord attached. For example, something like this.

As for the app, with all of your criteria, I would suggest Battery Monitor Widget

+1 on ccc71's apps -- I had several of his first-generation ones and recently took his generous offer to consolidate into Android Tuner (his all-in-one app). He has been great to work with on a dev level and his apps reflect his top-notch skills.

I've tried my nexus 7 charger with the qi pad and ran battery monitor widget.
Tablet showed at -432ma, sat it on the qi pad and it changed to -124ma!!
Why a negative figure ? I assume I'm using more power than its charging.
Would a 5v 2a charger male much difference ?

Hi
Just had a thought the value I'm ready is when the screen is on, out it being off make any difference ?

Try using currentwidget (free) to read just the current being provided during charge.
Set it to update at 1 second intervals.
Even with the screen on, if you are not using navigation, streaming stuff, gaming, etc. it should charge even if it is not getting the full 1.5A current provided to it. It would just charge slower not discharge.

As I learned from another thread, the cable makes a significant difference. After using a 2a charger, current widget, and checking the charge of all my cables: 2 provided about 1.4a, a few 1.1a,and a large number of cables cut power down to 600 down to 300.
You need a capable 2a charger, a quality cable that you have actually tested, and a qi charger that accepts 2a and doesn't lose a majority when converting to induction.

Did it happen to be this thread? http://forum.xda-developers.com/showthread.php?t=2609087
You might have read that from one of my posts hahah.
I've said in different Qi charger threads to have a good 2A charger and to replace the included micro USB cable with higher quality cables (premium monoprice cables, or the Motorola Ecomoto)
I did a video demonstration on USB cable quality here. Didn't expect that drastic of a difference.

Hi.
I'm using a nexus 7 charger
1st models charger is 5v 2a
I've tried the following cables: included, nexus 5, nexus 7 (1st edition and 2013) and a couple of other cables.. All with very similar results.
Think I'll send this charger back and then with a recommended one.
