Sfmn® 2016 New Mobile Universal Battery Charger + USB-Port for Smartphone Battery

We used this charger to revive the batteries on some old Android phones that were sitting with dead batteries for several years. They would no longer charge from usb cable and this charger was able to revive them. We can now retrieve old pictures that would have been lost. I'm very pleased with how easy it is to use and the price is great

I bought this even though some folks' reviews said the LCD screen didnt work, and were negative. It DOES work. I'm happy. Here's the thing. If the prongs ("+" and"-") are not lined up with the battery properly, the LCD screen will light up and show 100%, but not blink. And the battery will not charge. As soon as you line the the prongs up properly, the screen will blink, and your battery will charge. Easy peasy lemon squeezy. Watch for the blink. The prongs can and will move, so check when you put the battery into it...problem solved. I bought this because my charging port broke. Instead of spending hundreds of dollars on a new phone and losing all my data, I got this. Yes, it charges slow. But for less than $10 bucks, I'll do slow. Lol. Matter of fact, Im considering getting a second one, and getting a few extra batteries, which, even totalled out, is faaaaar less than buying a new phone. I live out in the country, closest neighbor about 1/2 mile away. I do depend on my phone, so having a gadget that works, and a few charged batteries, is worth the peace of mind... Bottom line: Buy it. Line up the prongs, watch for the blink, and you're good to go.

I like how the charger has adjustable pins depending on battery contacts orientation. It charges relatively quickly. I am using it to charge batteries for my old gaming handheld, Gizmondo, and also for my Nokia N-Gage batteries. It works as intended with no issues.

Long lasting battery charger. I've tried several. They usually burn out after a month. Well made.

I saw reviews saying it didn't charge fast or it didn't fully charge. If it doesn't charge to 100% it's doing you a favor. Charging in that manner wears this type of battery out faster. It is not a fast charger. Why? It is a "universal" charger. Fast charging technology is most likely proprietary to each company's individual phones. If you want a fast charger then contact the phone's maker to see if they make a fast charger for external charging. If you need more hours for your phone, purchase additional batteries and always have one on the charger. I have three batteries. Most likely you want a charger because like me your charging port no longer works. If you think my solution is costly get an estimate and find out how expensive it is to fix that port if it is even possible. This does what it can for close to every removable battery out there at a very low price. And some of the complaints are actually "features" that some simply are not aware of. I like my little unit very much. It has been a workhorse and easy on my wallet. Doesn't get any better if you have reasonable expectations.

I ordered three chargers before I got one that worked with my oversize Perfine battery for my LG V20. The best pat about having a phone with replaceable batteries is that you can carry spares, but it's sometimes useful to have a large spare that will last 2 days, like for long travel days where you use your phone a lot. It's also a bonus if you're with someone who also has a replaceable battery phone of a different type. EDIT: Forgot to mention a nice feature I have not seen mentioned. It's also a battery tester. Even when not plugged in, it will tell you the battery level when you mount a battery to it. It's a nice feature when you have lots of batteries, and are not sure which are charged and which are depleted. EDIT #2: Needed to take away one star. I just noticed that it does not top off the battery. I get more like a 95% charge.than a 100%. It also charges very slowly (like 12 hours or more!) . I could deal with the slow charging, since I usually switch batteries in the morning, and 24 hours is enough to finish a charge cycle, but the unfinished charge is not good. EDIT #3: Down to one star. Now it will take days to charge to about 80%. Not sure what went wrong, but it should have lasted at least a year. Some may think this can actually be a good thing to preserve battery lifetime, because the battery does not get hot when charged slowly, and not topped off. However, spare batteries are relatively cheap. I'd rather have my battery fully charged, and replace it when it starts to fail. It seems others are in agreement with this issue, and have taken away more stars due to these shortcomings. Still, it's the only external charger that works on my large extra capacity battery for my LG V20 phone. It can also charge other batteries for cameras, etc. I will still find it useful. At least it's not terribly expensive.

Awesome idea. Works great on several different battery styles I have.
