Looking for USB Car Cigarette Lighter Adapter

I have had about 5-6 of these.. every one I get my hands on is junk. When using the GPS, with the phone pluged in (non stock cable) I still end up killing my battery dead. The second it comes off the charger is turns off.
Can anyone point me in the direction of one that charges correctly?
Thx in advance!

I use my wife's from Verizon and it seems to work ok. It has a USB port so I can use my normal, thick data cord. You're probably running into ones where the cord is too thin to give proper charge. This one works great with the data cord.

I have the Samsung car dock. It seems to do fine with just GPS. I don't think the Epic can draw enough current to maintain it's charge if you're using any other features. If I'm running GPS + Streaming Music, it will discharge eventually and become very hot.
You need
1. a reasonable quality USB charging cable so that the Epic will draw the maximum current, or a power adapter that grounds the data pins. If the epic thinks it's connected to a computer it won't draw the maximum current.
2. an adapter that will provide 600ma+. I used the one from Griffin until it broke* and I bought the Samsung cradle. http://www.google.com/products/catalog?q=usb+car+power+adapter&hl=en&um=1&ie=UTF-8&tbm=shop&cid=1150301903319147928&sa=X&ei=4h0ZTtSyL4aDgAeA7rH0Dw&ved=0CIUBEPMCMAE
Hope this helps.
*Griffin agreed to fix it, but it's been several weeks since I sent it in. I'm a little unhappy with them at the moment, but the adapter was fine until it broke, maybe you'll have better luck.

seems like a good price. i ordered 3 single usb 1 amp units for 1.99. I'll give feedback once there in my hands.

sounds weird but goto radioshack or wherever & get one for a palm pre it works great charges really fast to, try & get palm brand because thats what im usin

Not as strange as you might think. As the pre/pixi charger is 1amp allowing it to power the touchstone with enough current. Most
12v lighter plug USB adapters are .5amps.
Also the pre/pixi lighter plug charger requires the cable that comes with it. And although it is a micro usb the end that goes in the lighter plug is not standard its thinned and narrower.

+1 on the pre charger... been using one since I had the pre, and it is awesome. phone still discharges when streaming pandora and running GPS, but GPS by itself results in a very slow net charge on my drive to work.
We sell a case logic brand charger at work for 15 bucks that is rated at 800mA, used it a few times and know a few people that have one. I'm sure online price is cheaper.

ive never had that problem mine always charges no matter what

I get mine off of EBay. Just make sure its output is 1amp.

USB and DATA cable
That's because if you use a USB adapter and a DATA cable the phone only charges at half it's rating. This is because it thinks it's pulling the power from a computer USB port and it doesn't want to overload (and fry) the port.
I picked up one of these, opened it up and soldered the two middle USB pins together. Now it allows my phone to charge with a data cable at it's max rate.

there are pretty sweet power inverters that run 30ams, so you can plug in laptops and such. pretty compact, AND they come with 2 usb charging ports.
there under 50 bux.

I use a j-lo brand car charger. Its for a gps and charges @ 1000mah. I also have a power inverter, the cheap one from walmart with 2 ac outlets and 1 usb port. Both of these work very well.

Nokia DT-900 Qi charger Teardown & Review

I picked up the Nokia DT-900 from my local Verizon store for $49. When placing the device on the charger it will charge cycle a number of times before stabilizing into a charge. Last night I had a issue where I had to remove and replace the device because the charger was blinking after failure to charge 10+ times. The positioning doesn't matter as long as it's on the keystone, although the Nexus slides off rather easily.
The stock adapter is +12VDC 0.75A. I tried hacking in a +12VDC 1.75A transformer for faster charging rates but the device failed to do anything. I re-spliced the stock transformer and it still works. With daydream activated the keystone maintains to drains the battery as it cannot provide enough charge to power the device. For $49 this product is a compromise to failure in wireless charging technology due to charging rate and slick surface.
Battery Mix reports +/- 10%/hour charge

Inside the device. The back pops right off with a proper tool. Notice the 3 temp sensors between the coils.
Underside of the circuit

The maximum charge rate is set for 789 mA and at 4ish volts this is less than 4 watts. When the battery gets full the rate goes down, so try again with an empty battery.
There is not much use in a bigger adapter.

This Qi charger isn't good, I tried it .

Nokia Qi charger and magnet
Hi, I'm sorry if the question is a nonsense but.... would a usual magnet, attached to the plastic cover of the charging plate, interfere with charging capabilities of the plate? or is there any Qi standard wireless charger, which would hold the phone with a magnet? would be a good charging accessory of the car.
thank you

Ended up returning mind and going with the WCP-300. Had little to no luck with these, zero issues with WCP-300.

I got one of these.. and the 1st few times I tried it, it was working great.. no issues at all...
now I can't get my N4 to stay charging for more than 5 minutes (then it stops, beeps, tries again, fails, etc)... I leaning towards returning it.

Does anyone know what the thickness without the casing is?

I've got some new tear down pics I will post soon. I just ended up using this charger in my car based on your review and a few others. thanks for posting this.

I would also like to know this!

I've heard no but it goes against the physics, so I'd say yes. It's not a good idea to have magnets next to a phone anyway, unless it's a weak case one. That ought to be OK on the charger too

Wireless charging

The only thing stopping this from being a perfect phone is wireless charging.
Maybe Sony will release an add-on to give it Qi capabilities?
How about using the Qi adapter into the micro-sd connector route? Would it retain waterproofing if it was plugged in?

The Z premium is powered by Qualcomms latest snapdragon 810 chipset. There is also another news is that smartphone has three version like premimum ,compact and Sony Xperia Z5.There are 3 generous GB of DDR4 RAM in the flagship, and 32 GB of storage, along with a microSD card slot for expansion. This feature must to be add waterproof quality.THat is why it may be the extraordinary feature.

The solution is to use this adapter with a case.

Will the phone still be waterproof if something is plugged into the micro-USB port?

No idea, i would assume that it wouldn't matter if anything is plugged into it, however that adapter isn't really dubbed as being waterproof so while the phone is waterproof the adapter certainly isn't.

HIi
I think your information is very informative and your information is given below again ( Posted by gregk232

May I ask why you want wireless charging?
Sent from my Nexus 5 using Tapatalk

USB port on the Z5 isn't covered with a rubber flap, so it must be able to withstand water bridging the wires in there, so I think it's safe to assume, as long as no power is applied until it's completely dry, just having something plugged in shouldn't hurt it . Though, as stated, the Qi receiver itself may not fair so well.

1) Convenience: It seemed silly to me too until I tried it, but it's actually way more convenient than plugging/unplugging all day. Just set your phone down and it's 100% when you're ready to go. I have a couple at the house and one at the office, now my phone rarely spends any time out of my hands not charging.
2) Durability: My girlfriend finally had to give up her Galaxy Active because the one part that wasn't bulletproof was the USB port. Once that gave out the phone was useless, but if it had Qi charging, with reduced wear it'd still be running fine. Additionally, Qi lets you charge (nearly) regardless of cases, unlike docks, which I usually had to take phone out of to fit in a dock. ...Which is why my Nexus 4 was naked when I dropped it. I wised up, got a Nexus 5 and a few Qi chargers, and have never had the N5 out of a case since.

Infuriating
Its so frustrating when companies go backwards with tech; big names like Sony should be able to add things to their products not take them away! The Z3 had magnetic charging and even my Z1 which is due for upgrade soon has a magnetic charging port.....! It doesn't seem like the Z5 has come on leaps and bounds since the Z1 which I would have expected by now!

I tried the wireless Qi card on the Z5, it works out to be about 10+% per hour but the phone really heats up.
Decided against it and went back to charging the normal way.

It's a shame that they removed the Magnetic Dock i was already planing on buying that phone, but after i saw it today in a Store i'm really not so sure anymore if i will actually buy it :/
I think i will just sit this one out and wait for the Z6 and hope that Sony will listen to us customers and give us the dock back or add qi charging into the phone without something from a third party.

Don't think magnetic charging will come back....

You might be interested in this, I think its due out by January.
Turns your micro usb into a magnetic port.

oh yes i have got some outstanding information from you.Thank you very much

I really don't like the location of the power adapter on the phone.
The length of the cable is also to short.

Will magnetic USB charge cables screw up waterproofing?

This is a question about magnetic USB cables and waterproof phones such as the Galaxy S8...
I assume you know what I am talking about when I say 'magnetic USB cable' ... One of those cables where you leave a magnetic 'lug' plugged into the micro usb or type c port on the phone so that you essentially get a magnetic charger setup similar to the mag-safe port found on Macbooks.
My question is, if I leave one of the lugs plugged into a waterproof phone, will the exposed copper pins cause the phone to short out in water (or even pocket sweat for that matter)? Does anyone have any experience with these cables (such as the WSKEN Mini 2) and using them in water? How does the waterproofing mechanism work on the phone's type c port? If it works by detecting a 'short' between 2 pins and disabling the port while wet,
maybe the exposed pins would create the same effect, depending on which pins are brought out of the type c port...

Hello, I'm not into magnetic chargers and there's no details about how it works at some point, however i thought about your question and it was simple to answer regarding the info available on the Internet.
the magnetics also will transfer the their energy into an electric one, thus, if you put it in water, you know how electrical energy and water go, so i don't recommend placing it in water as it will have the same effect as the normal charger,but while doing my researches, i noticed that some phones that after they got a wet port, the usb cable chargers didn't work, where as the magnetic charger did.
About the Galaxy waterproof
water can remain in the handset after it's been dunked – and if you add electricity, that can lead to terminal short circuiting. so if it was to detect something wrong with the amount of current running to it, it wouldn't charge and will warn you.
I hope that i could help answering the questions

I have direct experience with this situation via my Motorola G3 mounted on my motorcycle. This past week, the unit charged fine on a 600 mile trip, some of which was wet. However, on the return home, the phone went dead, and I realized it wasn't charging correctly. Upon disassembly, I found the magnetic lug visibly blackened on the "male" section. Evidently some moisture got in and things shorted out. In addition, the phone's charging port is now critical of how a standard usb charging cable is plugged in, so I assume there is some damage to the charging port, as well. Luckily, this phone's charging port is a fairly easy and inexpensive repair (<$10 part, no soldering). I did try to use a second mag cable and lug on the phone, but it was non-functional, hence my assumption of damage to the phone's USB port.

Noob asks: What is POGO and the Samsung Xcover Pro

POGO: I have Googled but cannot determine if it is a generalized interface type, a standardized proprietary plug/jack, an clever acronym, who knows. Would some kind soul point me at a tutorial?
Samsung Xcover Pro: Because I want a rugged smartphone with a removable battery and no bloatware, I got one of them. It's common else where, but not in the US. It's been my smartphone experience that one of the smartphone weak spots is the connection, which gets plugged and unplugged so many times, is around and collects crud...and when it fails, you are SOL. This phone has a POGO plug. Is there a USB to POGO cable for this phone? Since the US market presence is so small, you cannot even buy the replaceable battery, you have to get it shipped from Europe. Gamber-Johnson makes a nice cradle with a POGO connection for this phone, for a mere <gasp> $150
I know, I know, I am a masochist who always takes the path of greatest resistance (to say nothing of impedance and reluctance).
Maybe the simplest thing would be to get a magnetic USB-C cable to preserve the socket on the phone.

It's called a POGO because of the gold-plated pins. They are spring-loaded like a pogo stick. They are used in applications where a drop-in cradle provides support for the device that's to be charged.

I have purchased a Samsung Xcover6 Pro and I'm also looking at 3D printing a dock. Did you or anyone else find any electrical details of the POGO pins? Can we just apply voltage to the pins (in which polarity?) or is there a communications protocol required to enable charging?

Apologies everyone. I didn't think to check Thingiverse. There's a design here and it appears to accept voltage with VCC left and GND right.
XCover Pro Pogo Charger by xnappo
Remixed from @julvr's excellent work for XCover Pro. I used these pogo pins:https://www.amazon.com/gp/product/B07FQ52W88/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 (and I have a lot of them so....) 9V is needed for Quick Charging - could support higher but 9V should be safe for now. Once...

Good find! I ended up buying a commercial unit from KOAMTAC. It was expensive but I do not regret it after more than a year of use. The charger for a spare battery was a plus.

EDIT: oops..never mind...just realized I was looking at a different phone model..I'm a tool, lol.

I can report that I have designed and printed a cradle for my Xcover 6 Pro but the tolerences are very tight and it requires fiddling with the position of the phone to get it to work. I initially used a bench power supply which resulted in good charging speed but I connected to the positive and negative of an old broken (phone end) USB lead and I am getting slow charging speed from a USB charger. I assume that some circuit is required on the data pins to enable high current on a USB outlet. I have tried several USB power supplies.
EDIT: I have replaced the USB cable with a 5V 3.5A PSU (non USB) and AccuBattery is reporting ~6.5W charging speed.
I can also confirm that there is no increase in charging speed between 9V and 12V and charging shuts down at 12V.

Typical way of enabling fast charging is to short the USB data pins together, but this maxes at 1.5amps by USB spec, or 7.5 watts. Beyond that you're getting in to data signals to negotiate higher charge rates.
A fairly decent explanation is here - https://microchipdeveloper.com/usb:bc12
