Samsung Batteries on EBAY (OEM vs. Generic)

Anybody have any experience with the Generic batteries on ebay going for about $5.00 each. Are these classing "you get what you paid for" or are the oem version just way over priced?
Please advise.
Update:
Purchased two batteries + charger (non-oem)... They last half as long as the Samsung OEM.

I bought 2 batteries + usb cable + charger + car charger for $8.99 (+$3.99 shipping) http://cgi.ebay.com/2x-Battery-USB-...863749?pt=PDA_Accessories&hash=item3f02cc0145
I knew they where not OEM or even not Samsung (like the picture). But they work fine. I have no complain.

@floppy - Does the car charger put out decent amperage? Or is it slow like USB? Also, the picture makes the battery charger look like a monster - is it as thick as it looks? Can the USB port be used to charge a phone while it is plugged into the wall?
thanks!

If you are looking for a decent car charger, get the Kensington PowerBolt K39224US . It puts out 2.1 amps and fits flush in you cig lighter...

if the wall charger is anything like a previous one i've owned, the dock charges the phone and/or a standalone battery... maybe at the same time, but probably sucks :\

Does the battery charger in this package come with its own AC power adapter or do I need to use my Captivate USB charger (or other) to charge the batteries? .

If you look at the additional pics on others and read the specs, you can see the AC prongs on the back of the charger.

you guys know if we already have review of that in the main SGS forum
http://forum.xda-developers.com/showthread.php?t=733705

Also, if you read through the random shut-down thread, one of teh posts says Samsung is blaming the shut-downs on a charger/battery combination. It would be interesting to see if the aftermarket replacements cause such a problem or if its just a line of crap from Samsung.

I got 2 of the aftermarket batteries along with a charger and they seem fine.
not as good as OEM but do a great job as a backup.

I'm sorry I can't answer your first question because my car has an usb port and I don't use the car charger I received with the bundle.
About the size, it's not really bigger than the battery and yes you can charge your phone trhu the usb cable when in the same time your are charging a spare battery

Mine just shut down with the ebay battery.

I bought batteries for my Samsung, works fine. The package I bought has docking for an extra battery so I can have one fully charged at all times.

I think you mean k39242us, unless you need an iphone cable. This one is $5 cheaper, I'm getting one soon if anyone wants a review.

Like this? I thought since it has a usb port, it will charge at the same super slow usb speed?

Nope - the port shape doesn't mean anything. The factory charger has a female USB end and it charges faster then a PC USB port.
Keep in mind that all testing (even with an ammeter) shows that the max current the captivate will draw is about 700 mA. There is no reason for any charger that puts out more then 1 amp.
I bought the Griffin power bolt that has 2 1 Amp USB ports - so i can charge 2 devices at once. Also, most car chargers (with just the uSB port - no cable) need to have the data pins shorted or the phone will only draw 500 mA.
There are a couple threads in the Vibrant and i9000 forum that document all this. I modified an extra cable myself and now my phone sees my 1A car charger as an AC charger.

I just got these along with some other stuff.... the charger. The led is red when charging or when complete?

red when charging, blue when fully charged

Does anyone know if this kind of battery is gonna HURT your phone? I know that it might not last as long as the OEM one, that is fine. Just worry if this kind of battery can get over voltage some time that can be bad to your phone ... Anyone confirm about that? Thanks

I see this on the samsung site, 10 bucks more yields you a stand + charger.
Not bad...I am still debating. Wish it was a dock instead

car charger

Does anyone know - is a 1 amp (1000ma) car charger the recommendation on the mt4g? Where's the best/cheapest place to buy one? It seems like most of the time, amps are specified in product details.
Also, I assume if you charge off of your laptop usb port, that it'll be charging at 1 amp as well?

Belkin makes a micro usb charger that's 5v 1a. I think I paid 20 bucks for mine. It works well and is TINY. You can use it to charge anything that uses a usb cable.
http://www.belkin.com/IWCatProductPage.process?Product_Id=489423

IGo Makes a great line of chargers. I have their car and home chargers. They work great and if you get a different phone all you have to do is get a new tip. This way you don't have to contantly buy new chargers.

How about $1? Yes, $1.16...
http://www.monoprice.com/products/p...=10826&cs_id=1082602&p_id=6766&seq=1&format=2
I have like 5 of these, they work great. Just plug any USB cable in to it and you're set.

if your looking for cheap just hit ebay... you can get the generic's for like a buck with free shipping

i wont touch car chargers with a 10 foot stick... the electirical whine from the alternator distroys Li-Ion batteries...
i use usb to computer or to one of those "emergency battery chargers" just another Li-Ion batt, if you plug the emergency charger into the car, and the phone into the emergency charger the battery in the emergency charger will take the hit....
similar to a couple hundered dollar UPS i have on my server racks

This is a new one for me. Can you back that statement up with proof? (not being rude - just curious)
FYI: A good all-purpose micro usb charger is the Motorola P513 ~$10.00 with S&H on Amazon
Sent from my HTC Glacier using XDA App

i can poke around on the interwebs... but mostly thats from years of experience with phones, years selling phones, and chargers (RadioShack).
you can prevent all damage by charging the phone while the car (alternator) off, or by using a power inverter, or with the extra LIon batt solution i mentioned above...
NEVER plug the phone (directly) into the car, and then crank the motor, the (electrical) whine is at its worst as the alternator comes up to speed...
at the same time, this is what i tell all my customers:
"cell phones are convenience items, if its not convenient to do, then dont do it"
most people will find the tradeoff of having the phone charged "now" vs diminished batt capacity an easy choice to make... but not all people are like "us"
it surprises me that HTC endorses the use of car chargers with car docks...
but those 1$ chargers on ebay are the worst, most are non-regulated, and could dump 12V into the phone at the smallest problem. 12V will absolutely torch your phone...
you will do what you like... just food for thought

Car charger?

Before this forum was made, I was trying to find a car charger that would actually work. The majority of the ones sold on Amazon are just micro USB chargers, which obviously don't work for the a100. I found this one on another forum, so I bought one:
mobile.walmart.com/ip/Car-Cord-Adapter-with-Polarity-Switch/15050431
But when I tried another similar wall charging product, I had to exchange my tablet for a new one because the battery stopped charging entirely. So my question is, is this product (with the proper voltage settings, of course) safe to use?
This is the thread I found the product on:
acertabletforum.com/forum/acer-a100-general-discussion/1168-car-charger-2.html
A few people there claim it works, but I trust xda a lot more. Can anyone help me out?
Thanks, and I'm anxiously awaiting, like everyone else, some custom roms on this nice little device.

Since I didnt get any responses, I decided to just try it, and it worked fine. So if anyone else was looking for a car charger, this one will do the job.

It seems that the eBay one is better. It has 3A output vs the 2A from Walmart.
If you are using the A100 in the car it is better to have a charger with a higher capacity.

Wouldn't the additional amperage cause charging issues and additional wear on the battery?

Car charger specs
After several calls to Acer, I was able to have then confirm that the maximum voltage that should be applied to the A100 is 12 volts DC.
Your car is capable of producing 13 to 15 volts DC while running. Failure to use a REGULATED 12 volt charger could fry your tablet. Your tablet will draw aprox 1.5-1.8 amps while running AND charging. Anything that is capable of delivering 2 amps or better will be fine. A charger rated at 5 amps will Not ham your unit, it is just capable of delivering the required power with room to spare.
NEVER attempt to charge via USB, there is NO physical connection between the USB port and the battery charging circuit.
I have not been able to get the size specifications for the charging plug from Acer. If I can find my caliper kit I will measure mine and post it here.
Hope this helps.

i just bought an extra wall charger and use inverter. i have a 800watts inverter lying around. and it works fine.

So does anyone have a lead on a 12 volt regulated car charger?

I used an 85 watt converter and watched a 90 minute movie with no problems except the converter was rather hot when I pulled it out of the lighter socket.

I picked up a +12V voltage regulator from Radio Shack and soldered it into a cheap Chinese charger I found on Ebay, and it works perfectly. The regulator is only rated at 1.5A, but I'm never using my A100 while it's charging in the car.
Considering the minimal voltage change, I doubt that additional .3 amp draw would overheat the regulator anyhow.

Best portable battery?

Hi all,
I'm wondering if anyone has any experience with portable battery packs. I don't mean extended batteries either. I mean the universal usb charger kind that packs several thousand mAh.
I'm looking to get one for a nine hour flight, and I want to know what is a good brand.

I can't answer your question, but a lot of planes have a USB/charging input now. I know when I fly Air Canada, they have it.

I have had an Energizer XP18000 for about 3 months now and it has surpassed my expectations.
It holds 18000 mAh of power and will charge my Gnex and my Xoom at the same time (need to order a special tip for the Xoom/non standard device). I use it for long train rides to keep my phone topped up.
When watching HD video over 4G my battery level will drop about 1-2% every half hour, so it is not charging as fast as the wall charger, but it is enough to keep you from having a dead battery when you get to your destination. With my usage I can go 3 to 4 days and never need to look at a wall outlet.
The size is about as big as a external hard drive. There is also a wall charger that has a good size power brick in the middle of it. You can remove it when you don't need the wall charger, but I keep everything in one small bag so all I have to do is set it down next to an outlet and top up the external battery, then fold the cord into the bag and pull out what ever cord I need when I am on the move. It works just fine with the original Samsung usb charging cable.
I picked mine up from Amazon but you might be able to find a better deal if you look hard enough. They make a smaller model too that is only 8000 mAh.
I always keep it in my bag and it works so well for me that I don't even need the extended battery and leave 4G on all the time.
http://www.energizerpowerpacks.com/us/products/xp18000/

Beautiful. Thanks Dante. And yeah, I heard some planes have USB chargers now. Unfortunately I'm not flying with them. I live near YVR, but Air Canada is having a bunch of problems with their workers right now. Last thing I need is flight delays or bad service.

I did a ton of research before buying mine. I wanted a pocket sized one, that had large capacity (enough to fully charge the phone twice), and could charge a device at a full 1 amp. After much research, I bought the original version of this one:
http://www.newtrent.com/store/iphone-external-battery/iphone-battery-imp50d.html
Mine has less markings and I believe both ports on mine are 1 amp, where as the new one has one 500mA and one 1A port. Mine was also like $55, this one is on sale for barely over $40, an even better deal.
It is very powerful - 5,000 mAh will charge the phone 3+ times - much bigger than other "pocket batteries", fits in a pocket nicely (I wear cargo pants) because it's skinny, like a deck of cards. Fairly light too. Only complaint is that I bought it before MicroUSB became the new standard, so it charges with miniUSB instead.
I carry a retractable mini-usb cable, and a retractable microUSB cable, in an altoids tin, in in my pocket with it. Works great, can charge my friends phones at the same time as me. Had it for 2 years, still going strong!
There are newer designs they have now too if you look at their website.
It does take a long while to charge - 8 hours to charge fully or so if you charge off a 500mAh USB port, because it's a huge battery! a lot less maybe 4 hours if you charge off a high speed 1A charger.

i was looking at this one http://www.amazon.ca/Anker-8400mAh-...UTF8&coliid=I3IVVC4G6YETK&colid=1ILTNQ88L4FE5
it has a 2amp 5v port, this can charge a transformer prime with the screen off.

I got this one recently:
http://www.amazon.com/Anker-SlimTal..._1_2?s=wireless&ie=UTF8&qid=1335035472&sr=1-2
Its (much) smaller than my Nexus, has a built in micro-usb cable, and charges via micro-usb as well. While it doesn't have the capacity of those listed above (only 3200mAh), it was only $20 and the size really does let you take it everywhere.
It can fully charge it the phone from dead about 1.5 times.
I bought mine due mainly to the fact that it includes the micro-usb cable that hides away when not in use. It has a standard USB port as well for charging other items, but the appeal of only having to carry one item and no extra cable sold me.
My only complaint is that the built in cable could be a bit longer.
It has a flashlight too... lol

Been researching this topic lately and found that Anker's 10,000mah external battery is looking the best

I use the Veho Pebble and it's fine for my needs. I get 2 charges out of it.

after hours of my own research I also bought the Anker Slimtalk. I dont travel enough to need one that is huge and can charge my phone 8 times. This seems small enough to toss in my pocket and not bother me since its so thin and light. For $20 and the convenience of having its built in micro usb cable sounds like a perfect little invention to get me through the day.
If I traveled more I would of probably got the Energizer XP8000. Their tip program is awesome. Free tips for life but really its $2 shipping each. if you want this device to charge a whole bunch of things it can. My Acer netbook, EVO 3D, girlfriends RAZR, 3DS, bluetooth, iPad 2, Nook, and the list goes on. I've been trying to ask New Trent for almost a week if their products would be compatible with the Energizer Tip program but found that contrary to what I've read their customer support is terrible, but their prices are better than energizer. So they loose out on the sale since over the last few times of researching has allowed me to find the Slimtalk which for the price and for my needs is perfect.

Exactly why I went with it. Even while traveling I'm generally within range of a car or home charger, especially now that pretty much everyone without an iPhone has a micro USB charger somewhere.
I just wish it had a built in AC adapter as well but I'm sure the size would increase by quite a bit. Someone (iGo maybe) makes one like that but it only has about an 1100mah battery if I recall.

I found something here in the Netherlands, and I'm not quite sure if you guys in the US have the same thing..
The thing this has going for it is it's portability. It fits in your pocket, and if you don't mind a big lump in your pockets, it even fits together with your phone.
Click over there <<< to check out the dutch website of duracell. It basically is a battery with a socket plug on it, and 2 USB outlets.
Tech. info:
Output voltage: 5 volts DC
Input voltage: 5 volts DC, max. 1 amp
Capacity: 1800 mAh
Offcourse, this is the dutch version, with the dutch socket plug, but maybe there's an US version as well?

Thanks for all the info here guys. I have that crappy Black and Decker Pocket Power from a few years back, that well, isn't living up to the charge these days, so I need something else.
Still a bit too many options, but I'm sure I'll find one that works the best.

[Q] What should i look for when getting a car charger?Does USB cable make difference?

http://www.flipkart.com/belkin-f8z4...rger&ref=1121df98-c23e-4571-b4a3-5f8776ad5243
I saw this Belkin charger and says 5V and 1A charging capacity. I read that S3 maximum charging is 1A , so will this charger work ? or does 5V is not enough ? or go for 2A ?
Also does USB cable matter in charging ?

the usb cable makes all the difference.. ive used cheap ebay cables and they dont charge quite as good as oem or the mediabridge hi-speed i have.

I have just bought a couple of these cables:
http://www.amazon.co.uk/gp/product/B00FAAHT0E/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
and one of these chargers:
http://www.amazon.co.uk/gp/product/B00D82O68Y/ref=oh_details_o02_s00_i01?ie=UTF8&psc=1
as my Belkin 1A wasn't really as adequate as it could have been.
The cables may be a bit over-kill (and a tad pricey, but I took up the 30 day free Amazon Prime trial so got free next day delivery), but as a combo they work admirably and can cope with charging my S3 and my Nexus 7 (which needs 2A) simultaneously.

Can you guys suggest a brand which is available all over world.. both listed items are not available in india. And Cant spend so much too

USB is digital (except for power). Anything a bit pricier than the cheapest cable will do.

Get a cable like this, with a charger that provides 2.1a out of a single port. If you're on a custom kernel that allows you to change incoming amperage, you don't need the dedicated cable.

Where do people get the idea that a USB cable is gonna make a difference for charging your phone??
I've used ebay, dollar store type cables my whole life and have never had a problem other than cheap build quality where the cable doesn't last very long. It still passed the same power or signal as any well known and overpriced branded cable.
I assume these people are the same suckers who buy $100 Monster HDMI cables that work the same as $10 ebay or monoprice stuff.

Be careful with those "mini" car chargers. The cheap price is daunting, but I bought a package that came with 2 with retractable USB cords for only 5 US dollars.
The adapter would not stay firmly in the car and pull out whenever I tried to extend the cord to plug in my phone, and my phone's battery decreased while plugged in...
While this could've been a car issue, I'd just use caution. Instead I purchased a regular sized one with a retractable USB built in for only 8 dollars, I'll link you if you're interested. Good luck!
