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)

Costco charger works
I bought my vibrant at Costco and it came with some accessories, tested the car charger, it works.

Buy a cigarette USB adapter. Buy a micro USB Galaxy S cable. Connect the two. That way it works AND is more versatile than just being stuck for that specific phone/purpose.
I bought a Griffin dual USB adapter and a cable from amazon. Both were ~15. The Griffin has 2 USB ports so I can use the other for something else. Even if both are plugged in, it still charges the phone, even under intense GPS usage.

Bought the cheap $12 walmart charger for wifes Slide and it seems to work just fine for me.

I use the "official" T-mobile car charger I got for my Cliq. It works but charges the phone really slow. I plug it in on the way to work, about 20 mins, and it only charges it about 3% to 5%.

Before you write off a charger, use the hack in this thread to kick the phone into high rate charge mode.

Will the high rate charge mode whack out the battery life and send it to a quicker death?

It shouldn't. The hack is a HW one that shorts the data pins so the cable looks like a charging cable the current goes from 400 mA to 600 mA. Well within the supported range. The phone limits the current to ~600mA.

Agreed. The only reason there is a limit of 400mA is so you don't draw too much power from your USB and harm your computer. If you use a wall charger, it would charge at the full 600mA & all this is doing is making it so it doesn't get registered as a PC USB device.

bought a $6 one from frys but while it would charge the phones temp. would go up by 30 degrees and became super hot to the touch, needless to say I never used it again. It works great on my sons Ipod Touch though.

as I just posted a bunch of info here:

But this works:
http://www.dealextreme.com/details.dx/sku.25177
Status: Dedicated charger, not USB device, which is good because...
Widget reading: 1100mah
Basically we need any 1amp charger that is detected as a charger (rather than a USB device) and our phones will pull its max charge of about 1100mah (according to the widget)
If you already have a charger that is detected as a USB device, you can short the data pins (2 middle contacts, use a tiny piece of foil if you want =D) in your USB cable and it will then be detected as a charging device and pull the 1100mah.
I would love it if we could compile a list of chargers (wall chargers, car chargers, and USB chargers) that are detected as car chargers out-of-the-box.

I picked up a Rocketfish flush mount USB car charger. I hate Bestbuy, but was in a pinch and needed one. It works great and I can still close the ash tray cover on my VW.

Unfortunately it does show up as a USB device.
Max I logged was 863mA but average was between 855 and 860mA.

ah too bad, if the thing opens up easily, it might be fairly easy to connect the data pins (inside two pins of the 4 pins in the usb connect) and "convert it" to a dedicated charger.

Baught some cheap charger off ebay for like 5 bucks, made in china, looks like it should cost about 25 cents to make, doesn't work. Charges for 2 mins, then stops charging, then starts again, then stops, then starts then stops, just loops.
Used the costco charger, came with the phone, works good so far. But phone gets warm charging.
Also have a 40 dollar charger, works the best, no problems with it.

Posted this in another thread but this might be more appropriate:
Just use this charger by Samsung it is compatible with all Galaxy S phones according to Samsung and it is cheap $6.69! The widget shows and output of 1095 and these chargers support the Samsung rapid charging. Doesn't trigger the USB connection.

Also I found that some of the micro sd data cables will not mount.
Here is a compatible Samsung Branded micro sd data cable that does work with Mac OS and Windows $2.35!

Portable Chargers Comparison

For some of you coming from phones with removable batteries, you may have some anxiety about running out of battery life and not being able to swap a spare in. I was the same way a year ago, but I didn’t let that fear keep me from buying a newer phone without a removable battery. So I decided to just grab a few portable chargers to use and I’m glad I did.
Below is a comparison of the portable chargers I have. To try and compare them as fair as possible, the process was simple. Reboot the phone, fire up the stopwatch, set to 15 minutes, shut off the screen, plug in the charger, and leave it alone. The readings were taken from Battery Monitor Widget which was set to update the history every 60 seconds. I used a charging cable from my HTC EVO 4G LTE. I didn’t have my N5 charging cable with me and we know sometimes the cable can play a big role. So take that in to consideration if you think my numbers are off.
The portable chargers from left to right.
1.New Trent iCarrier 12000mAh Portable Dual USB Port - $39.95 (Amazon)
*The one I have is an older model which doesn’t included the “Recharge by USB” option. Mine can only be recharged via AC Wall Adapter. The new model has both options but doesn’t included the wall chargers.
2. Anker® Astro 5600mAh Portable Power Bank - $29.99 (Amazon)
3. Anker Astro Mini 3000mAh Ultra-Compact Portable Charger Lipstick-Sized - $19.99 (Amazon)

Review for Each:
New Trent:
I originally bought this to be used with my Nexus 7 (2012) since it was REALLY picky about what could charge it. You can tell this is a lot bulkier than the other two and isn’t something you’ll throw in your pocket. I keep this in my backpack and only use it when I don’t plan on moving around. Or if there are two people/devices that need to be charged. The plastic housing feels a little cheap, but I understand the idea was to keep the weight down on an already ‘heavier’ portable charger. It has held up well.
I’ve used this thing 3-4 times on my phones without it dying which is nice. This one re-charges using a AC Wall Charger (No longer included) or via USB (5v 2A…no charger included). NOTE: I have the older model which does not have the “Charge via USB” option. Only the AC wall charger option which it did come with. I can’t imagine how long it would take to charge via USB. It already takes a long time using the AC Wall Adapter.
Anker Astro:
This has been my Go-To portable charger for over a year. And it still charges my phone at least twice. When it comes to size vs. capability it is the clear winner. It also includes a LED Flashlight built in. There is a 4 light meter that tells you the status of the battery when charging a device or when being charged itself. Or you can just hit the button to see how full it is.
It can easily fit in your pocket or purse. I have a few very short micro-usb cables laying around so I’ll bring that with me too so I don’t have a 3ft cable in my pocket.
Anker Astro Mini:
I just bought this on sale and was surprised at it’s weight when it arrived. It has a metal casing so that probably adds to the weight. The fit/finish is very nice looking. When holding this in one hand and the Anker Astro in the other, you don’t feel much of a difference. Yes the Mini is round/smaller, but it isn’t a huge difference for me. The mini fits in your pocket nice.
If you are looking for something very portable, a little cheaper than the other options, and a charger that will charge you up once (maybe 1.5 times), then this is a good option. But if you may think you’ll need the portable charger for more than 1 charge while out, go with the Anker Astro (5600 mAh).

I have the Anker astro, but it takes AGES to charge my n5, almost as if it was being detected as a pc usb port rather than a charger.. any ideas? Stock rooted...

What cable are you using with it?
Get the battery monitor widget app and see what it says when plugged in.

Nice quick review.
Strange that New Trent 2A output is less powerful then regular usb..
And the average charging mA for Astro mini seems bit lower than it should be. Both Astros have the same output rating, arent they?

Review of MPow 4.2A dual usb car charger w/lots of pics!!!

This is a review of MPow 4.2A dual usb port car charger. http://www.amazon.com/Mpow®-4-2Amps-Charger-Android-Devices/dp/B00HLHHBHA/
Car charger is probably one of the most common smartphone accessories. We all like to take trips, stream our favorite music stations, keep our eyes on the traffic with Google maps, make some phone calls, and maybe even have wifi hotspot running for other passengers in the car. All this is going to drain your phone battery in no time. That's why we need to keep our phone on a charger while driving. And not just any charger, we need something that's going to source enough current to charge your phone at max speed. Let's take a closer look at what I found.
Both of the MPow car changer units, black and white, arrived in a nicely packaged box with a front display showing the actual charger. Taking it out of the box revealed a very compact dual car charger, about 3.5" in length and almost 1" across usb port side. When I say compact, I mean it was a size of a regular single port charger, while they were actually able to squeeze two in there. Another good point about compact size is that it won't take too much room in cigarette outlet and won't interfere with anything next to it. Once plugged into the outlet, it has a nice soft blue light to indicate the power is on and also to guide the connection in the dark. I do have to note that usb connection itself is a bit on a tight side which is actually good to hold the cable without falling out. But at the same time pulling on the cable will actually remove the charger itself unless you hold it down with your hand.
The most important test is if it can actually deliver 2 amps per port. A lot of the chargers claim they do, but it only works when one port is plugged in. In this case, I was able to confirm charging my Note 2 at max speed (the same reading I get from my original 2A Samsung wall charger), and I was able to do that while also charging Nexus 7 (HD, 2013 edition) which charges at 1.5A. Although I don't have two Note 2 to verify full 4.2A dual charging capacity, I have a feeling that won't be a problem.
Overall, I found this dual usb car charger to have great performance, solid build, and delivering it's advertised charging capacity without a problem. Covered by 18-months warranty and currently on Amazon for $6.99 (down from original $9.99, need to use code MPOW01CA at checkout) - this is one fantastic value!
Here are the pictures.

Good review. My car has a USB port built into the head unit, and it really isn't meant for charging. My Galaxy S III would just barely stream music via Slacker and hold the same battery percentage. If yoou're getting the same kind of charging capabilities out of this as you do with you wall charger, that's mighty impressive. I think I'll have to put this on my list of general accessories to get.

Hello Vectron, I just checked the amazon link, it's $7.99 now.

Do you know the lowest price of a car charger? I found many car chargers which range from $7.99 to $14.99.

Battery Cases? Slim battery pack with quick charge?

So coming from a Samsung Note 2, 3,and 4, I'm missing the peace of mind that carrying around a freshly charged spare battery gives. I always felt lame tethering a phone to a battery pack while waiting for it to charge. Well, I love this Axon 7, so there's gotta be some auxiliary portable power to make up for that.
I ordered This portable battery from Amazon that is supposed to be the slimmest portable battery that still has Quick Charge. I'll have to see how it works/fits and report back. If anyone has seen anything else similar, please recommend.
I did find a 6" USB-C cable to use with it so there's not a lot of extra cable to keep coiled when charging.
Also curious if anyone has seen a battery case for this thing?
I don't plan to use them all the time, but sometimes I'll be away from a charger and I need to communicate with work.

I'm using the Xiaomi power bank pro (10Ah) that has USB Type-C and also Quick Charge and my phone is charging insanely fast (30 min to 80%). I got the powerbank for 25$ on aliexpress.
ps: that 5Ah power bank in the link you posted is a joke, you will be able to charge your phone just one time if the powerbank is full. ( real capacity around 3.5Ah).

Thanks for the feedback - I'm actually looking for the slimmest/smallest power bank that I can get to charge in-pocket, as I already have a large 14,000 one that has QC that's about the same size as the Xiaomi one you mentioned. I only care about a single full recharge cycle - but one that does it as fast as possible for this need.

If you are happy with one charge then go for it.

I love these tiny phone-sized chargers as well - one charge is plenty for me as well (usually only need it when I'm walking around all day as a tourist or something). I just wish they would start to make some of these with USB-C cables built into them. I used to have one with built-in USB-micro and lightning adapter and loved it - when it was connected to the phone it was just like having a charger case in your pocket anyway...

Yes, I used to have one with the built in cable, too and that's actually the first thing I looked for, but being that there's not a lot of USB-C devices yet, I wasn't surprised that none existed with the built-in cable. Would be awesome if someone made one, though- I would immediately buy that if it was a single-charge slim w/ Quick Charge.

Just wanted to post my findings and pictures of the iKits unit.
Note that the shortie USB-C cable I ordered separately and does not come with the iKits unit! The iKits has a standard micro-usb that it comes with.Also be aware that the battery is labeled QuickCharge 3.0 - but that's only for charging the battery itself - I believe the capability to charge the phone is only at QC 2.0 (you'll see this sort of explained in the product description on Amazon link below).

I ran my battery down all day to about 34%. Plugged it with this cable and battery unit and was to 100% in a little over an hour, so I am happy with charging speed. Also in the battery stats "power management" area of the Axon, it definitely stated "Quick Charging" during this period.
I'm still interested in a battery case if anyone runs across one.
Here are the links to the cable and charger on Amazon:
$6.88 6" USB-C Quick Charge supported cable
$29.99 iKits 5000Mah Quick Charge 2 portable battery

So does anyone know of a case that fits the Axon 7 that has a built-in battery, similar to the Morphy JuicePack?
