Car Charger (Aftermarket or OEM?)

New pocketPC user. Got the Tilt a couple of days ago. First post, so forgive me. Very PC literate - still learning on the pocketPCs. Testing out ROMs now, thanks to all of you.
When I bought my case (Krusell), I just added on an aftermarket car charger (Fosmon). But I've been reading some of the posts about blown USB ports and a few other issues that seem like they could be power related. As a noob, did a ton of searching on the forum and can't find where anyone has given any opinions about aftermarket chargers. Part of me says stick to HTC or even AT&T brand because they are made for the unit (although an actual HTC is a pain in the ass to find and get shipped to me in Florida for an upcoming trip). Another part says they're all probably made in two factories in China and all I'm doing is paying more than twice as much for the same unit. Just don't want to risk having a problem on my new baby.
Any opinions?

I've been quite happy with my VersaCharger Pro from Boxwave -- works as a wall or car charger, and can put out the 1000 mA the Tilt needs.

Bingo! I've used Audiovox(HTC), Motorola and Blackberry home chargers, Motorola and no-name car chargers, my work laptop and my home desktop and all have charged my Tilt with no problem at all.

I'm interested in this particular topic too !
It's actually quite hard to get the specs (current in A and voltage in V) for official car chargers ! (and quite hard for many chargers).
The official wall charger gives 1 A and 5 V.
It would seem that you don't find that many mini usb chargers providing 1A.
You can find some on ebay but then most would provide... 5.5 V... could that arm the Kaiser ? I wonder, if anyone's got an idea.
Going for a lower current would mean the charging would be much slower.
Some extra notes about USB car chargers. Usually they will only provide 500mA and you won't have them work well with a regular sync cable (usb <-> mini usb) except if you mod them by welding two pins in the mini usb part (look for more information on the hermes section of this forum).

Today I had someone tell me that the best option for a car is actually an inverter with a home charger plugged into it. They said that Li-Ion and other rechargeables aren't meant to be charged via DC and that's why they sometimes (albeit rarely) brick via car charging. However, an inverter will prevent that. Sounds like BS to me, but I am not knowledgeable at all. Thoughts on this?

I flag BS! The charging circuits for the li-ion batteries are not built into the charger itself. Its built into the device. The purpose of the plug-in chargers is to provide enough current/regulated power to run the device and charger it.

Charging cable - Is it generic?

I'm in the UK and want to save $20 on the charger
I have a couple of Micro USB wall chargers that i use on my blackberry. They will fit the N1 and plug straight into the wall. Would they be safe to use, to charge my N1. (These charges are rated 750mHA).
I know the N1 will be supplied with a micro USB cable. I also have an IPhone wall socket plug head, the ones where you just put the USB cable into the plug and then it goes into the wall. Are these safe to use too, for charging the N1?
Thanks

the Nexus one connector is standar microUSB and therefore will work with standard microUSB cables and chargers.

So there is no type of resistor or transformer in the official plug head? ... to restrict power. I thought there would be as my blackberry charger has a 750mha rating on it.
I can understand the USB cable will work as its a limited power output from a laptop port. But just wanted to check the official wall outlet plug current isn't being restricted. The last thing i want to do is fry my new N1.
Cheers,

Just plugged mine into my old nokia classic micro usb and it is charging fine

The specs for the wall charger are 5V and 1A.
http://www.htc.com/europe/product/nexusone/specification.html

do what i did. remove the charger from your basket and use the supplied USB with an old htc charger if you have one. If not get one for a few quid from ebay why spend $20 when you can get one for $5 odd from the market/ebay.

I can only speak anecdotally, but I used a Blackberry Storm charger and nothing exploded

this mini, micro, A B stuff is annoying. to clarify for my simple mind, will usb cables that fit into my G1 fit into the N1? or is it a different size?

Last year, Micro USB was decided as the open standard for cell phone chargers, so this should be replacing Mini USB as seen on earlier phones (BlackBerries, G1) in instances where the port isn't.. some.. proprietary crap.

No. The G1 used Mini USB, this is Micro USB. The phone comes with a charger and USB (USB-A 2.0 to Micro USB 2.0) cable.

It's not propitary so it will work with any other charger.

It's a funny thing to find. It's too new to be widely available
I went looking for a car charger and a straight USB A->Micro B cable. The former I found by poking in all the packages for different phones until I found it (found a Samsung charger that uses it, although they did want nearly £30 for the damned thing). The USB A->Micro B I drew a blank - the more clueless salesmen tried to convince me that I was mistaken and I meant Mini!
I thought the blackberry used them but I looked in the pile of blackberry cables the local shops had and they were all mini. Even my local electronics store has every kind of USB imaginable *except* micro.
Edit: Found one! (might be useful for UK users). It's out of stock though... http://www.cableuniverse.co.uk/catalog/cables/USB-A-to-Micro-USB-B-Cable.html

Just so you guys know, not all micro USB's are the same. I bought a car charger from a local Tmo store last week (I forget what phones it was for), and although it "worked" when the plug was perfectly perpendicular to the phone, it had quite a bit of lateral play (which the OEM plug does not), meaning anytime it moved in the car, it would stop charging.
I returned it, and am now just waiting for HTC to decide to manufacture accessories for this ever increasing bundle of worry...

I am using a TomTom charger for my N1, also the HTC hero and the Motorola Droid chargers works to charge my N1.

Seems like it was just a poor quality charger. If it's a micro USB, it should be built to specific specifications. I already bought a few chargers (including a car charger) and cables (for work, home and travel), and they all work perfectly. Technically ALL micro USBs should be the same, unless the manufacturer didn't follow the standards.

Hah, just my luck; I pick up the one out of spec micro USB charger in the entire city!
Although, it must be that particular T-Mobile supplier, as I went to another store and test fitted the same charger, and it had excessive wiggle as well. Either that or my phone is just lame...

I just got a universal charger in Tesco for £5 that has changeable heads (Micro, Mini, Samsung, Sony Ericsson and Nokia 2mm)
Works perfect

- The cable is standard USB. You can use it to charge the phone from your PC, or use another micro USB cable or charger you have
- The Nexus comes with a US 2 pin charger that is dual voltage - works in UK and US. Just spend 50p and get a US to UK convertor plug.
- The charger is rates 5v 1A, so if you have another microUSB charger with the same voltage use that.
I find charging from the charger results in more battery life than USB. The only explanation is charge rate because USB is 500mA and the charger is 1000mA
PS. I removed the UK charger from the order too. You get the US charger regardless in the box.

Compatible chargers

Anyone else have any experiences they'd like to share using non-OEM chargers?
I use my HP TouchPad charger in my living room, as my HP Touchstone plugs into it usually. It charges the N7 at exactly the same rate as the OEM charger.
Just curious about others' experiences.
Oh....and is anyone else w/the HP TouchPad just completely spoiled regarding tablet prices? $250 seemed like a lot of money to pay, LOL.

http://saraoutlet.com/yxt-023-us-2-...for-apple-ipad-iphone-4g-3gs-white-35561.html
I use this, it charges my iphone, ipad, ipod touch, samsung, and now my nexus. I have one for the car as well that is 1A/2.1A.

the blackberry playbook 1.8a charger works really well. indistinguishable from the supplied OEM. available for $16 bucks or so in retail packaging.

I've used the same charger for my Galaxy SII. Seemed to do the job well and just as quickly!

I have a few blackberry chargers one is a playbook one and some other android chargers.. they all work just fine.

I'd love to know if there are any portable chargers that will charge the Nexus 7 without being plugged into the wall, so, I can charge it when I'm laying in bed or something, I have portable USB chargers that I don't thing would work with the 7 The Duracell Powerhouse USB charger and the Sony Media CP-ELS USB Portable Charger with 2,000 mAh Li-Ion Battery, I use them interchangeably with my iPhone 4S and Playstation Vita.

Okay, I went through my "wall wart" drawer and tried 8 chargers and 9 cables. I can't find any pattern to the results
There was one cable (skinny black generic USB) that didn't work with charger, and one charger (from a Kingston Wi-Drive) that wouldn't work with any cable.
The best cable was a white mini-usb (that I used with a mini-micro dongle) that had come with my generic 5000 mAH backup battery; it worked with *everything* except the Wi-Drive charger. The best chargers were the OEM ASUS charger, and a generic small black cube (1A) labelled "KIN"; those worked with every cable except the skinny black dud.
The worst of the working chargers were an "Innergie" dual laptop/USB power supply, and the generic battery backup. Those only worked with that white cable.
Honorable mentions go to an old Motorola RAZR charger (used with a mini-micro dongle) and a small Samsung phone charger. Those have permanent cables, and both worked.
I couldn't pick up any pattern in terms of amp rating (obviously, the lower amp chargers will take longer). It seems to be "luck of the draw".

I've tried probably 4-5 different chargers including a Motorola wall charger plugged in the wall, and also plugged into a power inverter in my truck, a motorola car charger and an oem wall charger and have no issues with any of them.

iPad 3 charger compatibility
Can anyone confirm if N7 charges using the new iPad 10W charger? Mine only supports the charger that came with it. Does that mean that the usb port is broken and I need to replace it or is it the way all the units behave?

It charges using my iPad2 charger, which I think is the same charger as the new iPad?

The Nexus 7 does not show charging when plugged into any of my OEM/aftermarket Apple chargers.
It does not appear to matter whether I use the USB cable supplied by Asus, or a standard commodity micro USB cable.
There is evidence from other users that the tablet may be charging at the 1A rate even though the charge indicator stays off.
I have not personally confirmed this yet.

I bought 10 of the HP Touchpad chargers for $5 shipped a few weeks ago. They work perfect for the Nexus 7, same plug, 2AH charging..

I've had one of those OEM/aftermarket Apple charges blow up on me (not shrapnel, it stayed in the plastic casing), so I wouldn't expect much from those anyway. Have you tried with any standard micro USB phone charger?

Chargers that work:
- Motorola Droid Pro (hard-wired micro USB). Rated at 800 mA but seems to charge almost as fast as the OEM.
- Kin One (Uses any USB cable). Rated at 1A, works with every USB cable I have (almost; there were a couple that didn't work with anything). These are available on-line for less than 10 bucks:
http://www.amazon.com/Sharp-Standard-Wall-Charger-CNR1002/dp/B005IY428Y
http://www.aftermarketcellular.com/ic/CNR1002.html
This is nice and compact; I'm going to order a couple of more to have as spares.
- Motoroloa RAZR (hard-wired mini-USB, used with mini-to-micro adapter). Rated at 500 mA. Works, but probably pretty slow.
- Samsung (from unknown phone; hard-wired micro-USB) rated at 750 mA. Didn't test charge time.
As an aside, I have a 5000 mAh backup battery that I've used with phones and my Nook color (http://www.amazon.com/5000mAh-External-Motorola-Blackberry-Nintendo/dp/B004P8E612). It works with the Nexus, but ONLY with the mini-USB cable that the Power Bank shipped with. Every other cable I've tried chokes. It's intended for an iPhone and puts 6.5V across the power pins (with no load; this is about the same as the Kin) and pulls the data pins to 3.4V. What's weird is that I can connect a 2-conductor (charge only) extension in series with the working cable, so that the data signal never reaches the Nexus. If I use a 2-conductor cable by itself, the Nexus doesn't charge.

When you say they work, are they showing as AC charging when you use them or are they just charging.
Go-to battery stats and it will say either

Or

Compatable car charger
It's really disappointing to know N7 is so picky about chargers. Can anyone report on a working small/short car USB charger that is compatible?

You might want to check that your vehicle can provide 2amps from its cigarette lighter plug. Normal only utility plugs can do that.

Car charging (or not in this case) how to monitor?

Little help chaps.
Ok i've just bought this http://www.ebay.co.uk/itm/390566738301
I presumed (not sure if rightly or wrongly) that it would be sufficient to charge my Nexus 4
I'm using an older usb cable I've got to charge it in my car however if i'm using navigation then the battery still decreases.
I've got a funny feeling that the cable is the culprit but i'm not 100% sure.
Is there anyway to monitor how much juice your phone is getting from the charge?
P.S in the battery monitor screen it says AC not USB
Thanks in advance for any help
Stret

Battery monitor widget pro. It monitors the mA that's being used, mV, etc. Maybe the phone is pulling more mA than the charger is supplying.

You need to go into your battery settings/status while your phone is plugged into your car charger.
It will show one of two statuses:
Charging(AC) and Charching(USB)
If it is showing charging(USB), then the phone is detecting a false data connection. This can be solved by taking apart your USB charger and soldering the middle two pins of the USB. These pins are the Data(+) and Data(-) pins. I attached an image of the two Data pins soldered together on the usb charger.
If it is showing Charging(AC), then your USB charger is not pushing enough mA to charge your phone. Most cheap car USB chargers are in the 500 mA to 700 mA range. The stock USB wall charger that comes with your Nexus 4 is 5V 1200mA.

Hard to say. From my experience, you get what you pay for. A USB charger that cost less than 2 GBP seems unlikely to support the kind of mA throughput that the Nexus 4 requires.
Some ways to check this are to check the power supply and draw through a battery monitoring app, use a different USB cable or the USB cable that came with your Nexus 4, or take apart the USB charger and inspect the hardware to see if it actually is built to support a 2A supply. That last one is a bit of a headache.
Here is an iFixit teardown of a similar USB charger which goes into detail about some of the working parts of a car USB charger.
To quote the final part of the iFixit teardown:
Quite simply, the device is a rebadged 500mA or 750mA USB charger at best. It is NOT 1A capable, despite what the sticker on the body says.

No problem! You should try and remember that the Nexus 4 is a pretty sophisticated piece of hardware. I'm not advocating that you go out and spend 20 GBP on equipment, but you don't want to use a cheap generic piece of trash to interface that electrical connection. The build quality of your charger can put your handset at risk to being damaged by electrical shorts and/or heat.
I would liken it to parking your sports car in a cheap parking garage on the bad side of town. Sure, you can do it, but there are risks involved!

1.8 amp car charger

Reading from the AC adapter, this thing can charge at 1.8 amps. I'm doing some research on car chargers that can output 2 amps to the phone via a USB cable, but the trick is getting the phone to pull more than .5 amps from a car accessory outlet. So far I haven't had much luck. There seems to be a lot of info on ipad stuff, but not much in the way of high powered Android devices. So I thought I'd start a thread about compatible car chargers that will allow a full 1.8 amp pull from my car outlet, and see what you guys and gals think and have tried. I've attached a pic of my current setup. It's a Proclip holder on a 2012 Mustang. I've used this same setup for several previous phones (S2 Skyrocket and S3). The holder itself is adjustable to accommodate various phones with cases.

Data pins need shorted together, either in the USB cig plug, or some micro USB cables are this way...

Additionally, the USB cable you use needs to have thick enough power wires to support 1.8A charge draw. Many USB cables use 28 AWG wire for the data conductors, and then you get varying degrees of wire gauge for the power conductors depending on manufacturer. Some people use 28 AWG for both, some use 26, and good cables are made with 24 AWG wire. The thicker wire gauge means less resistance so less power is lost and more can be put into the battery. To pull a proper 1.8A the phone probably should have 22AWG power wire in the USB cable really...

I have a custom 5 inch up angle micro USB cable I ordered from www.usbfirewire.com. It is a very thick wire, thicker than the charging cable the G2 came with. The one in my pic is probably not thick enough for a 2 amp charge.

Spot on. FWIW, the LG OEM cable is 20AWG on the power wires. This is the only viable explanation as I can't get the OEM wall charger to work with any cables I have sitting around (24AWG at best).

So would we be better off just using the factory charger with a power inverter or is there an actual car charger that will work?

Provided you short the data pins in whatever car charger you buy (if they arent already) and you get a cable with beefy power conductors then you should be able to draw 1.5-1.8A of power through a car charger. You have to make sure the car charger will do what you want though, many 2A chargers also have 2 ports to plug into. What they don't tell you is that each port is limited to 1A and both together will give 2A draw, but not to charge one device. The car itself also may limit power to the charger as well, I know my car specifically says 1.4A max through the cigarette plug. So it is possible to do, it is all just dependent on so many other things that you have to check off the list.

I like the Powergen dual 2.1A USB charger I got off of Amazon. Has served me well. But really, anything 1.8A+ that's quality will do. The trick is going to be the USB cable. Still trying to source one from a reputable site, but you want something with 20AWG for the power. If I find something, I'll post it. Thus far I found two sites, kinda obscure, but not thrilled that the shipping alone costs more than the cables which run $6.

I suspect the phone can detect the charger capacity because my OEM LG cable works on both the Apple and Non-Apple ports on the Powergen charger. Since that's the case, the phone doesn't seem to care if the data pins are shorted or not. And the Powergen is advertised as 4.2A total, so 2.1A per port.

Something worth considering is looking at charging cables labeled for tablets. They usually charge in this amperage range. I plugged my g2 into my kindle fire HD charger (1.8A) and didn't get any slow charge warnings.

Doesn't that come with the same Amazon branded usb cable you can get by itself? Take a look on the cable. A lot of times they label the wire gauge.

my amazon branded micro usb cables are 28awg and they still allow quick charge with oem wall charger.

The charging issues associated with this phone has been a huge PITA. I've been carrying my stock cable around just so I can charge my phone!!! Subscribed so I can maybe help out with some info...

Are you certain that's not just the data side that is 28awg? Very surprised you can pull 1.8A at 28awg.

They are unmarked.
