I'd bet the Captivate will only see it as USB port and never draw more than 500mA from it. You can check which mode your phone is charging in the settings.

Settings->About Phone->Battery status (first one on the list... when plugged in to the AC adapter that came with the phone it will say Charing (AC) under it)

I got a $3 AC car charger ("For blackberry" but thy're both just microusb) off dealextreme. The connector is a little tight but it works great and charges fast

I've found that my Zune HD FM Transmitter charges well too. Has a USB port on it. Not a cheap alternative, but it's multi-functional and it works. Think the Captivate recognizes anything to charge as long as it gives power...

I'm sure it will charge, but at only 500mA, will be pretty slow (especially if you're using while charging).

I use an old crackberry charger (has usb port on it). 500mA output. Charges phone fine. Just not as fast as the samsung 700ma charger.

I wonder if the iPhone charger would work for it? Anyone tried one?

I haven't tried the car charger, but the AC outlet->USB works great

I purchased the $1.16 car charger from Monoprice.com, and it works great. Unfortunately, board rules don't allow me to post a link. Just search for "car charger" on Monoprice, and it's the first one that comes up. Or, search for the product ID: 3523.
The only problem is that, while the label lists a maximum output of 1A, the Captivate only draws 500 mA from it (USB mode), as is the case with the other chargers listed in this thread. I have not found the lower charging current to be a problem.
For $1.16... It's a steal.
I also purchased two micro USB cables from the same site, the ones with ferrites, but I had to mod the plastic heads with a Dremel to get them to fit the angled port opening. They fit and work perfectly now, though.

Even with the stock 700ma wall charger, it takes almost 4 hours to completely charge the battery. A 500ma charger (most iPhone ones and generic USB ones) will take even longer. This of course assumes you're not using the phone for anything. If you're using the phone for navigation, for example, your 500ma charger will not have enough juice for the phone and the battery level will continue to drop. So, it is important to have the car charger that can supply more than 500ma to the phone.
Currently, I know the Zune HD premium car charger can be recognizd as AC charger and seems supply more than 700ma of juice. And I read some Moto mini-USB car charger (no USB port on the charger) can be used as rapid charger as well.
I've tried two different cheap USB port car charger, one labeled 2.1a and the other is 700ma. Both are designed for iPhone/iPod and hence can only be recognized as USB charger.
If anyone found any small USB port car charger that can be recognized by the phone as AC charger, please post here.

I've heard good things about the Scosche Revive charger. I saw it in a car charger thread on the Android Forums. A guy bought it for his Evo and said it charged nicely with everything running (GPS, 4G, Navigation, et cetera). Here's a link to his post reviewing it. There's also the Revive II which has a 2.1A port and a 1A port.

Thanks for the link. The big question is: Can Captivate regconize it as rapid charger instead of USB? Just because it works with Evo (HTC phone) doesn't mean it will work the same for Captivate. And I suspect the Revive II won't work well for Captivate at all because it is designed for iPhone/iPad.

I can't say how it'll work with the Captivate, but they were having the same problem with their phones (700mA chargers only outputting 500mA). So, I'd have to say there is a good chance it would work. I'd test it out myself, but I really don't need a car charger. My work commute is 10 minutes round trip, school is 20 minutes.

Anyone come across a good combination charger/mp3 adapter?
Oh and this got good reviews on Amazon: (eeeek can't post links yet)

Car Chargers

Hey Everyone,
Thought I would start a car charger thread.
I picked up one of these at Walmart the other day:
http://store.griffintechnology.com/smartphone/powerjolt-dual-universal-micro
And it works quite wonderfully. It's tiny, and even with bluetooth/GPS/Navigation running, it was slowly charging the battery. And it charges it quite quick if you don't have nav running.
It can be a bit annoying to pull out once stuck in, although you probably don't need to do that very often.

I have the single port version of the one you have cracking charger and sits flush worth the extra few pounds over the cheap ones and delivers plenty of juice

I got it the other day but haven't driven far enough yet to need to use it
Glad to hear though that it charges even while using GPS.

what is the exact output of each USB of this Griffen car charger ?
i have a JABRA charger (comes with JABRA Cruiser) and it doesnt seem to charge my GN while GPS navigation is on (even though its saying charging on the battery icon)
it used to work perfectly on my HTC Desire HD (with GPS+Bluetooth+WIFI ON )
any recommendation on how to fix this please ? like a reference output current that is enough to charge the GN while navigating ?
thanks.

The Griffen claims 1A per USB port, and I believe it.
Online reviews say some users with other phones need to mod the Griffen to charge their phone, otherwise it only supplies 100mA. Some crack open/mod the Griffen to short two terminals to get the full charging ability, and/or use a 'charging cable' which shorts the terminals within the cable.
As a reminder, the Griffen seems to charge the Note full blast, but perhaps something similar is needed for the Jabra. I suggest installing 'Currentwidget' to see what sort of charge you are getting.

SGP has one as well, it will lit up BLUE!

Thank you for the reply.
I have battery monitor widget installed & it shows charging via usb when i connect it to jabra charger, but the weird thing is that the galaxy note starts mtp mode once i connect it!
Could it be the cable? Or shall i just take the griffin charger to solve this?
By the way,griffin charger works out of the box out do i have to solder modify it?

I just bought this dual port 2.1A + 1A charger on eBay for £2.49 inclusive and delivered the following day....
http://www.ebay.co.uk/itm/2-1A-Dual...neChargers&hash=item19ca66b4df#ht_2865wt_1163
At first it seemed the phone was only drawing a "USB" level of current, so I was all set to rip it apart and solder the centre pins to force AC charging, but when I double checked with a dry run and a temporary short the phone switched to AC charging. Now it seems to be continuing to draw "AC" levels, so maybe I had a poor contact initially and a few (un)plugging operations have made the contacts more reliable. I'll try it out later today with satnav running and see if it keeps up with the pace and report back.
EDIT : Charge level draining like water out of a sieve with this thing whilst running satnav, and the phone said it was "AC" charging too. Switching ports didn't help.

i'm using the official car charger from my old nexus, the only charger i found can charge my phone with 3g and nav on because of the 2A output. other cheap usb chargers i tried with so called 2A output just don't work

+1.5A Dual Android wall charger?

I recently picked up an Anker dual car charger (link). It has two ports labeled Apple, the other Android. Both ports can supply 2.4A, for a total of 4.8A.
When I charge my phone from the Android side I get very close to 1A, but when I use the Apple side that goes down to around 500mA. To note, I used the same cable and only one port was used while testing. I used Battery Monitor Widget to track the charge rates.
Either side is strong enough to charge our phones, but it would be great if they both charges at full charge rates. So now I am looking for a wall charger and ideally I would like a dual port charger that can charge two Android devices at over 1.5A. I know we can't use 1.5A but it will future proof the chargers for a while, or will work with tablets.

Maybe look at getting a powered USB hub? I know the 2 I have at home can supply more than the 500mA USB2 spec as they've back powered my raspberry pi with a hdd attached before.

from my limited research, apple and android phones use different methods for signaling AC charging.
Android phones like to have the data pins in the USB cable shorted to each other to signal the phone for AC fast charging.
Not sure what Apple does, but it's not the same. That's why there are two different ports on the charger. Android ports have the data pins shorted together.
On a side note, you can also buy "charging only" cables on amazon that do the data pin shorting inside the cable. this may let you use your android phone with the apple labeled USB ports.

This is correct. Apple devices want to see some combination of 2V and 2.8V on the data +/- lines to signal wall adapter charging. They do it this way because it allows the charger to tell the device what amperage it's capable of delivering (500mA, 1A or 2A) which is pretty cool.

It's been my impression that even using an charging only cable/adapter an Apple charging port will only give you 500 mA.
For what it's worth I recently emailed Anker about this and they said as much. I don't have an appropriate cable or charger to test it on. But Anker also told me they will be releasing new chargers in December that feature their smart charging port which detects what type of device you've attached (Apple, Samsung or generic Android) and then behaves accordingly. I just ordered one of their external battery packs (Astro3) which has one of these ports for 2.1A plus 2 x 1.5A Android ports. A similar AC charger would be nice if you can wait.

Wireless charger question

I just purchased a white 32gb Nexus 5 to replace my Galaxy s2 that is dying a slow death. The phone is currently somewhere in transit via the usps. I am currently stationed in Italy and over here the outlets are 220v, not 110v. I want to purchase a wireless charger for my N5. I would purchase a 220v charger here, however, I am headed back home to the states later this year. I would hate to buy a 220v charger here, only to have to sell it, and purchase a new charger when I get home. So... anyone with a wireless charger, can you tell me if your particular charger is dual voltage?

The Qi chargers themselves are universal and don't use the 110v - 220v. So don't worry about that and pick up whatever Qi charger you want. They are all DC 5V 1.5A - 2A input. They generally just come with the charging plate and a USB cable (unless you buy for example the official Nexus 5 wireless charger which also includes the power adapter that supports 100 - 240v anyway). So you can plug the Qi charger using USB into a PC if you really need to (charges slower though).
What you will need to consider is the AC adapter/wall wart (what plugs into the wall, with a USB port or micro USB cable attached) that you usually buy separately (make sure it is 2A output). The AC adapter is what you need to make sure supports 100 - 240v. Most USB wall adapters are travel adapters by design, so they already support 100 - 240v. So it really shouldn't be a problem for you, but just double check it before you buy one.
For example, an AC adapter like this: AC 100 - 240v Input → DC 5V 2A Output. Then you just plug whatever Qi charger you have into it.

I have a Qi charger in my car which I typically only use during my 30 minute commute to and from work so I mostly do not lose any charge during my commute. I am looking to get another Qi charger to use at home and I was wondering if wireless charging stops when phone is fully charged. I am worried that wireless charging will stop in the middle of the night when phone gets charged giving me a partially charged phone in the morning.

Mine just uses a 12v DC input and it came with a 110v AC to 12v DC transformer so worst case you might just need to buy an adapter. But then again my charger was less than $25 shipped: http://www.att.com/shop/wireless/accessory.chargers-nokia-wireless-charging-plate-sku6290260.html

Question about the charger included in the box

As I've seen in some early reviews, the charger included in the box has a USB-A female while the charger included has a male USB-C output in both sides, so the question is: How the h*** do I charge my device with the included adapter?

The cable that comes with the phone is USB-A (male) to USB-C (male)

This adapter (Micro USB female>USB-C male) comes with the phone. It'll allow you to use your existing micro USB cables. It definitely won't support 25W USB-C fast charging speeds, you'll need a proper and supported USB-C cable for that. I'd guess it'll support standard (last year's) fast charging though.

At some point, the idea of USB -C is to have the "C" connector at both ends, and eliminate the "A" on one end. However, they clearly have not moved in that direction yet.
This would make USB -c omnidirectional in every direction. No wall side/device side and no up and down.

It seems like C on both ends is the proper way to migrate over, on the other hand buying A to C cables lets me re-use my wall plugs. Either way it's going to be a mess while my tablet and external battery pack are micro USB and my phone is USB C. What's everyone else planning on doing?

Qi Wireless fast charging is the way to go. Overnight I'll use the Wireless Charging Cradle and in the car I'll use the usb C cable to QC 2.0 Car charger. On the go I'll bring the OEM wall charger and cable. If need be maybe invest in a USB C External Battery Quick Charger.

For wireless charging which I use heavily, nothing. The Note7 will fast charge wirelessly at the same rate as the Note5. I ordered a 1' A>C Orange-E (they're 100% spec compliant) cable to use in my car for Android Auto. When the price drops I'll order a second Samsung OEM adaptive charger and Type C cable which I'll use in the office when I need faster charging than I can get through wireless. I'll use what comes in the box at home and when I travel. The latter is most important to me because that's where 25W charging matters most. A4C.com has the OEM Samsung 10,500 mAh fast charging brick on sale for $29.95 so I ordered one and that'll charge at 2A, last year's fast charging standard. I connect wirelessly 90% of the time for data transfer so Type C doesn't offer a lot of benefit on the data side for me so no need to "cable up." With the adapter that comes with the phone all existing micro USB cables will work fine. The only thing the adapter inhibits is 25W charging speeds. YMMV.
