I'm looking for a "small and lightweight" auxiliary battery or charger that I can use when I have no access to an AC outlet to preserve the phone's battery charge. A small device that I can connect to the microUSB port of the Captivate with a short USB cable while I watch my movies. Preferably with a built-in rechargeable battery, but would consider a device that can take AA or AAA rechargeables. I know I can get a couple extra phone batteries with a charger for a few $$$ in eBay, but I want something I can take out of my briefcase and in a second connect it to the phone without the inconvenience of having to remove my Amzer Argyle case and the back cover of the phone. I'm afraid I'm going to stretch my phone case out shape by taking it off and putting it on, mess up (loosen) the locking mechanism of the back cover or will end up, somehow, bending the simulated carbon fiber back cover. Not to mention the fear of dumping my coffee on the internals of the phone while it sits with the back exposed on the food tray of a plane/train/bus or on whichever surface I happen to be having my coffee. The icing on the cake would be if this auxiliary power source could also serve as a phone stand.
Thanks in advance for your suggestions.
I ordered one of these - there are other variations; but this is 4000mAh (so almost 3 times our current battery), The USB port is a full 1A, and will also charge my camcorder battery. They do make one with 2 USB ports:

It was $25 when i ordered it last week - now it is more.
Tekkeon MP1550
I've been using this to charge several usb devices on the go. i had it for several years now. its better if you pair it with sanyo eneloops.
its $14.99 @ newegg $22.30 on amazon
Many thanks for your suggestions... but is there anything smaller? That Energizer XP4000 looks like an excellent option at $25, but at $50 it is a little too big an expensive.
Edit:
I just ran across the Duracell Powersource Mini.... Anyone using this with a Captivate? Also, does anyone have any details on the specs of the battery in this powerpack? I could not even find any details in the Duracell site.

Duracell
I also found this one, but for $1.49 I don't know if it'll end up killing the phone. But it could be nice rechargeable AA batteries.

I won't buy anything that I can't find tech specs on - so the Duracell unit could be 1000mAh or 3000mAh - for the price i would say it is around 1000. The 2 AA chargers have to up the 3V to 5V and so the best available power is about 1000 mAh (i base this on the altoids chargers specs using 2 2500mAh AA batteries).
If all you want is a 1000 mAh in a small form factor, Target sells one (the Energizer XP 1000) in the store for about $20 with a bunch of tips. Keep in mind that our batteries are 1500 mAh so you won't get a full charge.

The Duracell appears to be the exact same device as the Xantrex Technologies 852 2051 Xpower Mobile Mini. If this is the case, then it appears to be a 3000mAh device. I like this charger because it has a built-in mini USB connector and a separated regular USB which makes it very convenient. I wonder who the OEM is... Duracell or Xantrex?
I also came across the IOGEAR Gear Juice Mobile, but based on some of the users' reviews it appears to have have 2000mAh rechargeable battery.
I saw that one that looked like the Duracell but i could not be sure. Wherever you buy make sure you can return if it is not what you want.
It seems hard to find much that is 1500 mah or larger without getting to big.

It is good enough;
The good news is that Xantrex makes both and they are 3Ah. The only down side is that you are limited to .5A charge - same as USB. I picked the Energizer as it is capable of 1A output, although our phones only draw about 700 mA max.
Wait one other downside - miniUSB not microUSB so it won't fit our phones without an adapter. This must be an "old" product as the spec sheet says it fits "New Motorola phones such as RAZR and ROKR" neither are made any more.
Given that the Xantrex appears to be an old product I have continued to look around for an auxiliary power source. I found the Kensington K38056US which has a microUSB and a MiniUSB output connectors and uses a regular built-in USB connector to charge. So the element of convenience is very high given that it can also be charged with the Captivate charger. Only thing is that the battery is 1200 mAh, but it appears to have an output of up to 1000 mAh. Amazon has it for $30. The specs sheet says that it started shipping on 5/1/10 so this one is a "fairly" new device.
In terms of power I have not yet found anything that matches the Energizer XP4001 for its size, but it is a little heavier than the Kensington (5.4 onz vs. 4.0 ) and you also have to carry an additional AC adapter.

hey...sorry for irrelevant posting...but your name sounds familiar ..! are you from Pune?
btw Splash Intense 5400mAh should work with captivate, 5400mAh is lot of power, i guess it can recharge captivate at least 3 times considering its 1500mAh battery..
Well, I just received the Duracell Powersource Mini which I ordered from Amazon as it's on sale for $19.50 down from the MSRP of 59.99. The [URL="http://www.amazon.com/Xantrex-Technologies-852-0251-XPower-Mobile/dp/B000R9T3T8/ref=pd_sim_ol_4"]Xantrex Xpower Mobile Mini [/URL]which is the same device is still selling for $45.50.
I added a music CD to my order as the Powersource Mini is eligible for free shipping on orders of $25+. Given the Powersource has a Mini-USB male connector and a regular USB female port built-in, I also got a shorter 2.5ft USB to Micro-USB cable from ebay for $2.99 to use with the Powersource Mini. (Also with free shipping and it fits perfectly in the Captivate) This short USB to Micro-USB cable will be used to charge my Captivate and the built-in Mini-USB connector will be used to charge my MP3 player and Camera. The Powersource Mini comes with a USB AC charger and a USB Vehicle DC charger adapter which gives me added flexibility.
The only issues I have found, so far, is that the DC input port of the Powersource is proprietary, so you always need to carry the 4.5ft USB charging cable and "possibly" the AC adapter. The USB AC adapter that comes with the Powersource is just a little bit bigger than the USB AC adapter that comes with the Captivate. A very negligible size difference, but I'd be afraid of using the Powersource AC adapter on the Captivate for prolonged periods of time as it "might" damage the phone. In the description of the AC Adapter of the Powersource it says that it is a AC/DC "Switching" Adapter. This "might" mean that it's designed specifically for the Powersource to switch off when it's fully charged. Also the output specs of the Powersource adapter are 5.5 volts 800mA compared to the 5.0 volts 700mA of the AC adapter that comes with the Captivate. I'd be nice if I only had to carry one AC adapter. Any thoughts on these USB AC/DC adapters being interchangeable?
Edit: In a previous post it was said that this device might be old because it had a Mini-USB instead of Micro-USB connector. A sticker on the device says that it was manufactured on 09/26/2008... So it is a bit old, but not extremely so.

Its only a 1500 mAh, but its pretty compact and it fits around your wrist.
Seems more convenient than a typical power source.

Did you ever buy this? I'm considering one for some travel and wondered how it worked out.
http://www.energizerpowerpacks.com/my/products/index.php#externalbatteries
I have both the XP2000 and XP8000 and both work very well.
I can't link but I bought a "Satechi icel 5200mAh" batter extender off amazon. It will charge my phone 3+ times before I need to recharge it. I use it to travel. Works great with all my portable devices as long as they use a USB charger. If I could take pictures I would show the size against a phone. I've put them both in a jacket pocket before without worry

I have a portable charger with capacity of 1900mAh. Its lightweight Its output is 4.5 to 5.5v 800mA Max. Though the charge time is around 2 to 4 hours, it would be rite for your need and purpose. I am not sure of Thinkgeek, but if you can check gadget store Chinabuye, there are more ranges of power charging, you can check and choose the better one, I ordered it from them at reasonable rate.

I got one of these from xs cargo for $10, at 3000 mAh it can charge the phone completely and still have some juice left. The non-usb charging port is annoying, but i've been thinking about modding it.

Just purchased 2 or these today. Getting ready for my new Nexus.. I charged these up and to see if they are working put a Iphone 5 on the charger. Neither one of these chargers will charge this phone. Says on the site and the booklet that they support Iphone 4 and 5. Any thoughts?
Found the answer.
Models that Require a Wireless Charging Case / Cover Adapter:
Samsung Galaxy S4 i9500 use directly if the QI receiver built-in back-cover case of the phone, if not QI wireless receiver is required
Samsung Galaxy S3 i9300
Samsung Galaxy Note II
iPhone 4 4s 5
The 4 and 5 if I'm not mistaken does not have qi charging capabilities, I think you need the qi receiver case for the iPhone to work. It's for all the iPhone.
The device will only charge wireless if the phone supports wireless charging. The Nexus 5 will work out of the box, a Galaxy S4 you would need the special back cover they sell. It will not charge any iPhone wirelessly at all. Not unless you had a special back or piece that turns the iPhone into a wireless charge ability. It will charge an iPhone though using the usb cable, maybe thats what it means by charging an iPhone.
This charger is best of both worlds, you can keep it on your desk for wireless charging and take it on the go if you have a long day.

If the price were a little cheaper I would bite but I'm not sure it is worth the price? Someone who has the product want to convince me?
Too expensive for something made in china.
Typical external battery efficiency = 70%
Typical Qi efficiency = 70%
6000x0.7x0.7 = 2940
Expect the phone to charge less than 1.5 times if you use Qi for power.
You'd better use it as a normal external battery that can also be used as a wireless charging pad.

Since the efficiency is so low, if you want to use it as a backup battery, you'd better use a cord instead of using qi.
As a qi charging pad connected to AC, it's fine, though.
I just got this today;
http://www.ebay.co.uk/itm/Qi-Wireless-Charger-PAD-for-Samsung-Galaxy-S3-Note2-S4-Receiver-10000mAh-Battery-/141047804367?pt=US_Cell_Phone_PDA_Chargers&var=&hash=item20d71ab1cf
basically the same, a qi charger with a built in battery, but with 2 outputs.
great idea to have this as a qi charging pad at home and on a long day can unplug it and have an external battery pack charged and ready to go!
only downside is there isn't a light to show its charging the phone via qi.
I love this charger, IMO it's the best. Here is my review on it, highly recommend it.
I've been using this for a couple of months with my N4 and N7-2013, and it works flawlessly, though I can't speak to 'true capacity' as I've never drained it fully to test # of full recharge cycles it provides.
There's a slightly smaller capacity unit also available (I can't post links yet, but search Amazon for "Qi 4800mAH") that may or may not be a better option, the benefit of that smaller unit being, well, size, in that it is more pocket friendly. Though if you would also use your Qi for a tablet, the slightly larger footprint of the 6000mAH unit might be preferable.
How fast does these Qi wireless charging charges the phone?
I got the LuguLake charger Wednesday, and I must say at first I was impressed, however shortly after I was very, very disappointed. The flaws I have found, at least with the unit I purchased:
Does not charge a 2nd device while plugged into AC power
As of yet, I have been unable to get it to charge the internal 6,000mAh battery since I depleted it once.
I'm going to keep toying with it over the weekend, but either I got a defective model or I'm doing something wrong. Also, anyone with one of these bother to "read" the guide / warnings? I just have to remember not to torture the battery, and to be weary if it ever becomes smelly!

This math is incomplete and may not work. You're ignoring voltages. At what voltage does the 6000mah come out at? Assuming the standard 5V that the USB output is at is usually the wrong assumption for these things - they're often 3.3V. If that's the case, you need to step up the voltage as well.

the 20-30% loss for standard power banks comes from exactly this in combination with any losses in the charging circuit of the phone.
I think the point is that you get crazy losses if you need to both change voltages, and do wireless charging from a limited power source.

I purchased one of these and sent it back. It worked great with the nexus 5 but I was never able to get it to work with the nexus7(2013) I believe I received a faulty unit. The customer service was great but it would just not work properly. I bought a "Maxboost Pulse 10000mAh Dual 5V 3A USB External Portable Power Battery Pack Charger with Digital Display (Piano Black) - Compatible with Apple iPhone 5S 5C 5 4S 4 ; iPad Air 5 4 Retina 3 2 1, The New iPad ; iPad mini retina 1 2; Google Nexus 5 4 7 FHD 2 ; Samsung Galaxy Note 3 , Galaxy S4 S3, Galaxy S4 Mini S3 Mini; HTC One M7 Mini M4 ; LG Optimus G2 ; Samsung Galaxy Tab 3 7.0 8.0 10.1 ; Kindle Fire HDX 7.0 8.9 ; Nokia Lumia 1520 1020 920 900 [3 Charging Connectors + Carrying Case Pouch]" from Amazon for $35 (had coupon code) and I am looking for a separate wireless charger
Just wanted to pass this savings along for a Anker 48W 9.6 Amp 4 port USB car charger for $11.99 w/code at Amazon.
I have 3 of the Anker 2 port car charger but found that 2 ports just wasn't enough for my needs with all the electronics that I have. So when this new 4 port car charger came out from Anker, I bought 2 of these at the $14.99 regular price and they are worth every penny.
This car charger came in handy last week on my trip with the family as I had a GPS, 2 cell phones and a tablet plugged into this thing and it charged them without skipping a beat. Also this charger has a rather small footprint given that it has 4 USB ports.
It is one of the most powerful car charger in the market. 48 watts of power (2.4 amps per port or 9.6 amps overall) lets you charge up to four tablets, smartphones or other devices at full speed simultaneously. I recommend this charger to everyone and it would also make a great gift.

You don't think 10A out of car socket going to blow your fuse? I would worry a bit having 4x plug connected to a single socket with every charging port loaded.

Someone made a similar comment:
"4 ports and "9.6 Amps" is all well and good, but keep in mind the fuse rating of the car's port. I would say they range 5-10A. "
And here was a reply/explanation:
"That is 9.6A at 5V which is 48W (as also indicated in the product description). Figure 80% conversion efficiency (it is likely better than that) and you are looking at the car port delivering 60W. Worst case scenario is car off and battery voltage at 12V. That would yield a current of 5A. Better case scenario is car is running and at 14V. That would yield a current of 4.3A. Either way, you are far from maxing out the circuit. "

Hi,
i've bought a wireless charging receiver on ebay, but charging is very slow (450-500mA).
Someone has a receiver with "fast charge"?

I got a receiver similar for my 10 but the port is black instead of silver. I just used it in my Tacoma (has built in wireless charging) and I gained about 8% in my 30 minute commute. Not the fastest thing in the world, but with my streaming and phone calls, I'm happy with it filling up a little though it may not be a ton.
Don't have a pad at home yet so I can't test it fully. But looking around it seems that a product like this isn't gonna be some miracle fast charging solution. The majority of these pads are 10 or 15 bucks so you're gonna get what you pay for. I'd love to see a fast charging version though.
I have very good experience with this product:
Nillkin Brand New Magic Universal Qi Receiver Tags Wireless Charging Pad Coil USB Receptor Adapter
This fast wireless charging stand allows you to charge your phone in portrait or landscape more. Very useful when placed on your desk next to your computer while you work.
Unlike other chargers, this one does not overheat and does not overcharge your device. The green indicator light will not bother you while you sleep.
It’s compatible with cases up to 4 mm thick (I haven’t tested with a thicker case).
