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

My old phone doesn’t charge anymore. This allows me to charge the battery outside the phone. Practical.

Great product, arrived quickly, well made and well packaged. Obvious how to use without instructions, if the user does a bit of research on batteries - specifically, what the two or three battery connections are (+, - and overcharge if present). Purchased it for a camera that came with a ZK07 battery and no charger. Looked for months for both replacement batteries and/or chargers. The camera is great, but of course useless without a charge in its odd-sized battery. Figured out how to use the charger in "seconds". Plugged it into a wall outlet and was immediately shown that the battery had a 25% charge, which was correct. The display blinked and showed a numeric state of charge, to 100% in about 1 hour. Delightful! Saved the day.

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.

The Sfmn® 2016 New Mobile Universal Battery Charger + USB-Port for Smartphone Battery was purchased during august of 2018 for the price of $8.99 plus tax. It's now available for $9.99 plus tax (December 4, 2024).This universal battery charger is a must have for those who have phones with removable batteries. It was a life saver for me during a time when I couldn't charge my phone battery for reasons that have yet to be determined. Basically, it's an easy fix. I had 2 of the same battery...while one was being charged, the other was being employed.Recently, however, it seems as though most of the phones are being manufactured with batteries that are not removable. That could just be my experience , though.In any case, for the price, it's an excellent accessory to have...just in case.

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.

The media could not be loaded. I recently purchased a Docomo FOMA P906i online, and the seller didn’t provide a charging cord unfortunately. So, I decided to look online for one. On Amazon Japan, they have it for cheap, but I was not willing to spend 20 USD in shipping fees, and it wouldn’t arrive until next year. I thought of a device such as this one as an alternative, and decided to bite the bullet to see if it worked or not. At first, I put the battery inside the bank face-up and that didn’t work. However, when I flipped it backwards, it started charging like so!! I’m pretty satisfied with this charging bank at the moment. It fits my battery perfectly and it’s a low priced device that seemingly works well. Although, the only small thing I find questionable is that there seemed to be scratches on the screen, which wouldn’t come off when I wiped it. Otherwise, I’m satisfied!
