Nexus 7 Car Charger

I was just wondering if anyone here has spotted a Nexus 7 car charger? Does it not matter if it's not specifically made for the Nexus 7? I'm trying to find one to buy online and I'm having some troubles. First post here I think I came to the right place though. :laugh:

Clicked thanks on accident lol. Any USB car charger should work, but I would make sure you grap a 1 amp one just so it has enough output to charge the tablet at a decent rate.

probably better with a 2amp one. samsung makes one for the tab2, about $12 on amazon, and just use your own microusb cable to connect to it.

Yup, go with a 2Amp one. Most of the cigarette lighter usb chargers are 2.1A.

Avoid the cheap Chinese 2+Amp car chargers, they can be so badly made they cause enough interference to wipe out your FM radio.
/edit 1Amp will be fine but don't go lower, the N7 would likely burn it out.

FYI I tried a 5v 1a wall charger and my gnex7 said f u wouldn't take the charge. 2a or nothing I say

Do you already have the Nexus 7? If so, can you take a look at the charger and see if rated at 1A output and/or try to charge it with a charger that came with your phone?
I am just curious if it can actually charge with less than 2A. The charger listed in the Play Store outputs 2Amps and I thought most tablets require 2A to charge.

Still waiting, should only be a couple of days now though...

I know this is something most people never do...but if you read the manual for the Nexus 7 it says you can charge it on a standard USB port with the Nexus 7 in sleep mode (no doubt because the power draw is much less). Standard USB ports are typically .5A...sometimes less. I would say that's the actual minimum. For the fastest charging 2A is what you want though.

The ASUS charger that comes with the N7 is rated at 2A (10W). I tested an old BlackBerry 0.85A (~4W) micoUSB charger and it seemed to work fine and the N7 didn't complain though I didn't do any scientific tests against the charging rates.
The 0.5A (2.5W) chargers probably won't even charge the unit if you're actively using it.
Cheers,
Kermee

Yeah...read my previous post...the manual says you can charge on a standard usb port (0.5A sometimes less) but only if the Nexus 7 is in sleep mode...ie you're not actively using it. If you can't charge it while connected to USB and it's in the sleep state...then your usb port is probably a low power USB port (<0.5A).
For those looking for a good backup battery charger for it...I recommend this one: http://www.amazon.com/gp/product/B005NGKR54/ref=oh_details_o05_s00_i00
works perfectly with my Nexus 7 (just make sure to use the correct USB out port on it as only one of them is 2A)

DealExtreme Charger
Saw this one on DealExtreme, even come with cable:
http://www.dealextreme.com/p/car-ci...-port-for-google-nexus-7-tablet-146751?item=8
Will be ordering will update when arrives. Also they're carrying Nexus 7 Cables in Pink, Green and Orange.

Was using a Sprint micro-USB plus charger (model PVX8823) with attached cable and standard USB port for 2nd device that I was using for my phone. Output is 0.65Amp which isn't sufficient and will slowly drain the N7 battery while in use. ~$35 at Sprint retail store. Wouldn't recommend for obvious reason.
Fortunately, had a spare Motorola SPN5400A 1Amp I bought with some screen protectors from Amazon because it was cheap like ~$5. 1Amp is sufficiently to maintain the charge while in use at near worse case running 3D games like Dead Trigger, Shadowngun, etc. So, 1Amp is minimum threshold.

You need a charger that:
1) Is capable of 2A (1.5A may be sufficient, 1A is a little too low)
2) Shorts D+ and D- together - This rules out most iPad chargers.
If it says it is made for iPod/iPad it will not work without modifications or adapters.
Samsung tablet chargers will work.
If you take an iPad charger, open it up, and short D+ and D- together, it will work.

Most chargers for android phones will work. I use my HTC charger for ,mine and I bought a car charge that has the standard micro USB connector but also has another USB port so I can charge 2 devices at the same time with 1 charging unit. You droid razor charger will work just fine. You just need to locate a charger that is capable of charging 2 devices at the same time such as this one

Check out this oem charger from Sprint. Its a dual port charger with a 2a output and you dont have to worry about buying a knock off charger that may or may not perform as expected. It also can be used as a wall charger. Good price too....

So are any of these confirmed 100% to work? the one a few links back (GTMax) says works with iphone, and I thougth that meant would NOT work with N7. So I am confused on what will work, and I am already on my 2nd Nexus7 being I blew out the USB trying a bunch of differnt chargers for the car.
I would like something that is small and can have multiple USB plugged in, but not a show stopper, just hope to find something on Amazon (Prefer Prime) so I can oder with my case today. Really want to use this in the car more (GPS\GoogleMusic..ect.), but with no power not a great option.
Thanks in Advance,

[Q] Charger

Can someone tell me if the Htc One charger is the same as the One S please.

Most chargers nowadays unless an iDevice are the same 5v micro usb

Thanks, just making sure. Replacing chargers and car chargers and HDMI adaptors is almost as expensive as the phone itself. :laugh:

Careful. HTC does something funky with the wiring in their chargers and phones such that, when using a non HTC charger, the phone will only charge at 0.5 amp, vs 1 amp with an HTC charger. Net result is that your phone will take twice as long to charge with a non HTC charger. There are several threads on this subject, and I've observed it first hand on my One. The non HTC charger shouldn't hurt your phone though, only your patience...

I've never had an issue.. have had HTC for years now and have gone thru several chargers bought from walgreens and they all seem to work fine. I usually charge overnight anyway so I never time the charge lengths. Ymmv I guess?
Sent from my HTC One using xda premium

I usually charge overnight as well. But I travel a lot, and when I do the GPS - a battery burner - gets a lot of use. What got me started exploring this, was when I saw my HTC ONE battery going in the wrong direction (slowly) while charging in the car while using the GPS. This led me to learning more than I ever wanted to know about HTC chargers and their funky wiring ... Apparently you can get around this by shorting two wires in the USB cable, but I have no intention of trying that!

I don't think the problem is at HTC but the charger you might have. I have successfully charge @ ~800mA (1000mA = 1 Amp)with different chargers ( Asus charger, Samsung charger and a newer palm charger). My new blackberry charger can charge @ ~600mA.
If I use my older palm charger, my Nokia charger, my old blackberry or a dollar store charger, it will only charge @ ~3xxmA.
If you read the spec carefully, you will see most newer *smartphone* charger max @ 1A, and older charger max @ 500mA. (or my BB charger max @ 800mA. )
So it's OK to use non HTC charger, just be sure to read the spec and find one charger =>1A.
Hope this help.

I'm on the lookout for a car charger someone can confirm will charge the One at full 1A speeds. I don't mean one where it claims to on amazon's site, but that you've actually witnessed it. Thanks for any help!

That is correct, usb specification is 5v, with 500mA (0.5A) maximum, hence the modified cable you refer to. The simplest way if you don't wish to modify cables is to buy HTC car charger

You can find HTC chargers on amazon that will give you the full 1 amp. Look for older phone models like treo pro or mytouch 4g and they'll be cheaper but work fine.

What happens if I charge the phone with a 2am charger? Does it damage my battery? Will it charge faster?

The charger *should* only provide 2A if the device (phone) request it.

Just thought I would chime in on some observations here. Long story short, when I bought my HTC One, I left the charger in the box and continued to use my multi-port USB charger with 3x1A ports and 1x2.1A port.
When connected to the 1A port, I found it quite strange that my phone was taking 4 hours or longer to fully charge. Also observed the same thing when connected to the 2.1A port. I was thinking that something was up with my phone somehow limiting the maximum charge current.
Anyway, I read a suggestion to use SystemPanel Lite to check for USB or AC power connected and sure enough it was reporting USB power. I remember the case with my Xperia X10 where you have to short out the two middle (data) pins on the cable or in the charger so that the phone detects that it is being connected to an actual charger. I tested it with my old Xperia charger, another generic USB charger, and the HTC charger and managed to get SystemPanel Lite to report it as AC connected.
But here is the interesting part. I have a car charger rated for 1A. Initially it never worked with the Xperia X10 until I opened it up and shorted out the two data pins. It has worked ever since. However, when I connect this to my HTC One, it still reports it as USB connected.
This has got me thinking that there maybe something more than just shorting out the two data pins for the HTC One to detect that an actual charger is connected. Just some food for thought.

Don't tell me HTC pulled an Apple and we have to buy only HTC chargers to get full speed charging? Does anyone have a confirmed non-HTC car charger that reports "AC" charging in SystemPanel Lite?

As per my post, I tested a generic USB 1A charger (it's at home, but it was one that was supplied with a Netcomm MyZone) and with my stock Sony Ericsson USB 700mA charger, both of which reported as AC connected. There has to be another way that these can be detected as chargers other than a simple short of the data pins.
Tested not to work so far has been an iPhone charger, Amacrox AX025-TACH1, Philips Power Bug, and two generic USB car chargers both with the data pins open then shorted.

Non HTC charger plugged into wall reports ac power. Proof

Good point. My apologies. The work "car" managed to be skipped as I read it.

Well, here's a new one..

Last night on my brand new One, I was wifi tethering when I got the message that the phone was using more current than the charger could provide. This was on ac power, which the phone indicated. I never had this problem on the previous One that I exchanged for a screen problem. The phone will literally run its battery to zero sitting on the charger.
It is happening still after multiple reboots and different chargers/sockets.
Is this a faulty battery? Faulty charging circuit? How would I go about finding out?

well if you got the coconuts you could hook a vom to the battery and then the charger and see the difference...

The charger that comes with the HTC One is a joke... 1,000mAh. I only use 2,000mAh chargers. I don't know how much amperage the One can pull with the fast-charge feature disabled in firmware, though.

I'm no expert but I'm pretty sure the fast charge feature is only so it will pull a higher current on USB charging mode. Thus far I haven't had any issues with my stock 1000 mah chargers I have laying around. The only time I lose power while charging is when I'm on a weak charger like my BlackBerry or samsung charger (750 and 800 mah)

Has anyone tried this charger?

My dog ate my charger and I'm looking to buy this one till I order a new one. Anybody have any thoughts on it?
http://www.bestbuy.com/site/insigni...lack/5690015.p?id=1219148349637&skuId=5690015

Seems like it would work but there are two things i would like to point out. First this is not a quick charge 2.0 charger so fast charge will not work with it, it will charge at normal rate. Also for myself i try to get wall chargers with removable cables just in case my pet eats thru it I can replace them easily and trust me i have gone through 4 cables in the last 4 months. That said i have had good experiences with ones bought from Ebay as well since the prices are far too tempting.

Is rapid charge the same as quick charge?

Usually not at all. What people claim as "rapid charge" is just a small increase in amperage (usually 2+ amps). By reference, USB 2.0 spec is 500mA.
Quickcharge 2.0 increases both the voltage and the amperage it can supply (is. even more wattage). The exact values are negotiated by the phone and what it draws - which is dependent on the current phase of charging.

Here's the exact same one we got with our note 4, OEM and everything! Plus it's way cheaper than the insignia one

Note, however, that the owners manual says fast charge doesn't work when the screen is on. So if your goal is to keep the phone charged while using Navigation or other battery draining apps, a QC charger may not help.

I use the Quick Charge 2.0 version of the exact same modal and it works fine. It is normal that the phone gets a little warm during charging, it gets warm while charging with the original adapter as well. You can always turn of quick charging from the settings.

Not to highjack the thread, but what about the bases (wireless charger themselves)? Which are compliant?
