Excellent alternative if your phone's charging port is broken! Saved me
I ordered this universal battery charger because the charging port on my phone is no longer working. I cannot afford to purchase a whole new phone at this time and thought this was an excellent solution to my problem. I have a Samsung Galaxy Express so I was worried it might not be compatible as my phone is not a very popular model. The fact that you can adjust both the pins and the piece which holds the battery in place made this no problem whatsoever. When I first placed my battery the light stayed blue which would indicate it was fully charged and I knew this was not the case. My battery had been dead for 4 days. I just had to adjust a pin to be touching a different gold plate on my battery and the light was pink which indicates that it is charging. After an hour, I placed my battery back in my phone just to be sure it was charging and it showed it was at 1/4 battery life. I was impressed as I had said my battery was completely dead when I put it in the charger. I put it back in the charger and let it charge until the light changed blue which took about 6 hours total. My battery lasted me a significantly longer time than it ever did when I was able to use my charging port. I was able to use my phone for about a day and a half which was never the case before. I feel like this charges my battery MUCH better than the traditional method of using the charging port. I don't understand the negative reviews on this. Perhaps those people were using it incorrectly or they got a faulty charger. I love this thing. I am getting more life out of my phone during a time when I am financially restrained $8 is much more doable than $200-300 for me. I appreciate that this even exists.
EDIT: Just thought I would add, if you are in the same situation as me, purchasing another battery to charge while you use your phone isn't a terrible idea. I found myself missing my phone while waiting for it to charge. Extra battery=never without my phone.

I got a charge out of this!
Odd little charger. It has two adjustable pins. Comes in with minimal instruction on the back of the box. But it said it would correct wrong polarity automatically so as not to damage the battery. The side slides and captures the battery and it takes a few tries to get the positive and negative contact of the battery aligned with the two pins on the charger when in place.
I have to say it felt cheap and I did not think it would work. It works like a champ! When the pins are right and you insert the battery, the charger indicator light will be blue indicating the battery needs to be charged. When you plug it in the light is pinkish red while charging. When the battery is charged the light turns back to blue.
Update: 22 May 2015
This little gem still does great! Because in the past and future I will review items given to me to try and review I always disclose that. I never ask first but some ask me. So to clarify, this was not given to me to review. I bought it, as most of the things I review, for myself.

I have a galaxy note 2, and the battery ...
I have a galaxy note 2, and the battery is not what it used to be. I got one of those portable chargers, but it would take forever to charge a battery that come with the note 2, and it was not only a little heavy to carry around all day (I commute a lot for work), but it was also a little bulky. I decided to get a second battery for the phone, and not have to carry the extra charger.
Now this does work, and it does charge Both batteries (one is the original battery which came with the phone,and one is an Anker battery purchased from AlumiGogo.
this is not a simple insert and charge. Although the description correctly states that it works for my phone, the charger has 2 connectors. Both batteries which i own have 3 connectors. So you have to move the connectors on the charger (they slide to fit different size batteries) for it to connect to the second and third connector. If they are not on the right connectors, they light on the charger will turn on, but will not charge the batteries. You can tell that the batteries are being charged when the light on the charger turns red after it was plugged in. If you know that the battery does not have a charge, and the light remains blue, then your batteries are not being charged. There are no real instructions included with the package, (other than what is on the box itself), so I had to play around with it to get it to work. I was on the verge of returning it when I figured out how to make it work.
So in conclusion. yes it does work, but be cautious when buying this product.
UPDATE: I have been contacted by the seller and they helped clarify the issues. They were very helpful, and now I can say I would recommend this product, and this seller. For this price, this charger can't be beat.

"Onite Universal Battery Charger" - A Better Choice To Charge A Battery!
Exactly as described. Would buy again. Would recommend. Great product!
I gladly submit a highly positive review on "Onite Universal Battery Charger".
"Onite Universal Battery Charger" features an adjustable spring-loaded door and sliding prongs.to accommodate various shapes and sizes of numerous 3.7/3.8 volt batteries. This here battery charger does a better job at charging cellphone batteries than if they were charged in their respective cellphones. It provides a rapid, efficient charge without overcharging or overheating. Batteries are charged in approximately half the amount of time usually required to charge a battery within its compatible cellphone. I left my cellphone's battery in Onite all night. Neither the charger or battery became overheated. The charger did not overcharge the battery, either. "Onite Universal Battery Charger" is quite intelligent, as it knows to stop charging a battery when it reaches a full charge. "Onite Universal Battery Charger" also features a USB output port in which a cellphone or other device can be charged at the same time. The charger has a lit indicator, which, eventually, changes from purplish-red to blue as the charging process is completed. By simply looking at this charger, I could not possibly ascertain how durable it actually is. All two hundred pounds of me accidentally stepped on my batteries buddy. It did not break a bit. So, its plastic construction must be pretty sturdy.
Briefly described, this practical product does exactly what it's supposed to do, and performs the necessary task extremely well. "Onite Universal Battery Charger" exceeds expectations, safely and quickly charging batteries.
"Onite Universal Battery Charger" had been initially brought to my attention by the recommendation of a supervising technical expert.
By the way, this product review is with pertinence to my third order of an "Onite Universal Battery Charger". I kept two for my own use and gave the most recent purchase as a gift. Besides, I do, indeed, intend to buy at least one additional "Onite Universal Battery Charger".
I certainly recommend "Onite Universal Battery Charger" to my fellow AlumiGogo customers.
Hope my product review serves as beneficial toward my fellow AlumiGogo customer's buying decisions.
Okay, that's about it. Thanks for reading my product review. Good Onite!

Universal model has some quality and design issues but overall does work
The first charger broke one of its pins the first week, probably because some batteries don't fit well in the universal model without wrapping a rubber band around the charger and battery to hold it in place. When I wrote a review, the seller immediately contacted me (good customer relations department!) and sent me a replacement. The replacement universal model works fine with Samsung Galaxy S4 batteries as the spring door hold the battery against the charging pins well. However, skinnier Galaxy S5 batteries are just about as wide as the slot and thus tend to get pushed away from the pins. A rubber band across the battery can fix this. Advice - be careful with the pins as they are fragile. Several reviewers commented that there were no instructions. My package did contain instructions on a tiny card which simply say that one aligns the battery against the sliding pins to align the pins with the + and - on the battery, using the sliding door to hold the battery in place (which it does not quite do with S5 batteries). The instructions also say the polarity of the pins does not matter as the charger recognizes the battery polarity. Overall, for $8, this is an acceptable and useful charger.

I love this product! Works perfectly! Saved me from buying a new phone!
I was about to buy a new cellphone, because where I connected my charger to my phone broke. However, I thought maybe there is some type of Universal Cell Phone Battery Charger I could buy. It turned out there was! I bought this charger and LOVE IT! It works perfectly! It charges my battery about the same amount it took for my regular phone charger, but I don't care, it WORKS! So easy to use, too!
I had previously bought a new battery for my phone as well, months ago, because I thought my old battery was going bad. I had decided to keep that battery, no idea why, but I'm glad I did. It turned out there was nothing wrong with that battery. It had to have been the beginnings of my charger plug going out on my phone. So I actually have two batteries for my cell phone.
I'm able to use this charger for both batteries! So I always have one in my phone, while the other is charging.
I love the fact that this charger is a smart charger, and automatically stops charging when the battery is full!
Thank you for making this product! You saved me from needing to buy another phone!

This Onite charger is 100%, without a doubt, worth the money. And it's not that expensive for the freedom it gives.
I've been doing a lot of road trips recently, and wanted the ability to swap out batteries instead of constantly having the phone plugged into the car adapter when on the long drives back and forth.
Charging both batteries through my phone was honestly a nuisance and just not healthy for my phone, so purchasing this was a no brainer.
It also helps that there is a USB port on the side of the charger, so that charging both batteries simultaneously (one in the phone, one out) is a possibility. The sliding door adapts to any size battery, and the prongs are movable as to accommodate the - and + ports. Really happy with this purchase and will recommend.

Rapid is a relative term. However, I would say that 6.5 hours to get a 60% charge doesn't qualify as 'rapid'
3 stars because the battery fits, it does charge (albeit slowly) and the price is affordable. All in all its functional value is 3 stars
Pragmatically however it would be a solid one star as that is just a ridiculously slow charging time and is not practical for a backup charger. Typically I need a fresh battery around the middle of the day (5 or 6 hours into work). If this replenish rate is indicative of future rates I will be looking for a different model. Fingers are crossed that SOMEHOW the slower charge translates into a longer battery life. not likely but one can dream.

I absolutely love this little baby! I have an older Galaxy S4 phone, and as typical of this phone, the charging port has weakened, resulting in the phone not getting fully charged. I was having to charge my phone three times a day even though I do not play games or watch videos on my phone. I purchased a second battery and keep one charged in the Onite Battery Charger all the time. It is so nice to have a fully charged battery when I need it. And it's a lot easier for me to carry an extra charged battery with me than it is to have to deal with a plug in charger or a car charger. I had questions when I first got the Onite Charger and had to contact customer service. They could not have been any nicer or more professional. I would definitely recommend this product to anyone who wants to keep a fully charged battery on hand.

It performs as promised, I do not have to buy another phone.
I was hesitant to post a review fearing the product would suddenly stop working. Quite the opposite has happened. The reason I purchased this product was that my phone will no longer charge using the standard power cord. I have an Android. While the charger does get hot, just a warning, it has successfully recharged my battery every time. The charge is relatively quick. Since I do have to power off my phone I will use the charger after hours while I working or piddling around the house. I would recommend this anyone in a similar situation or to someone who has a second battery and wishes to keep it charged as a backup. The product has more than delivered on it's promise. Yes, I would purchase another one without hesitation.
