Power banks/portable battery chargers

I was thinking on buying one and was wondering if anyone can give me an opinion/review on any
thanks in advance

I have the New Trent NT120T. It's the highest capacity I found and works well. It has 2 USB ports to charge 2 devices simultaneously. They also have smaller ones available that would be more pocketable.

im a little bit skeptical about these Chinese brand batteries, im afraid that they may provide extra current to the phone and burn the phone

I have the 5000mAh battery backup that's On monoprice for like $27. Has 2 USB ports, one at 1 amp for phones and another at 2.1 amps for tablets. Really nice build and charges my Nexus 4 fast. I def recommend it.

I have an Anker SlimTalk 3200mAh with which I'm very pleased. Slim, lightweight and it has a built in USB cable which means you don't have to carry another cable with you, although I wish the cable was just a little bit longer. Very good value for money.

Ahhh, they are out of stock and it’sbackorder gotta wait.
I like Monoprice they are great supplier/retailer AND they’re in SoCal just 30mins from me

Another NewTrent owner. But I have the 10000mAh one. Not too thick and charges quickly too. This one has two usb ports as well. I got this on sale at Daily Deals for $50 bux.

Looking for a good portable battery

Just switched over from a gs3 to a nexus 4 and I like the phone but the one thing i miss is being able to carry a battery and swap em when I wanted. So now im looking for a portable charger I see anker has a lipstick 2600mah and 3200mah slim. Any recommendations ? maybe different brands.

I use the 3A dual port charger from monoprice and it works very well. I understand that you probably are looking for something smaller since referencing the lipstick models but I can say that monoprice items (especially simple ones) tend to work just fine and are also usually pretty cheap.

i am using this one too and it's one of the best 5000mah packs out there, the capacity is real since i can charge my nexus 7 fully with it and still have a bit left and it charges fast too.
be careful with those ones that greg linked that attached right to the phone without cable. It is very easy to damage the micro usb port on your phone with it. It's ok if you just leave it on a table but throwing soemthing like that in a pocket or backpack can be risky. Might be ok with iphone since the apple socket is a lot more robust than a micro usb.

I bought this and I have to say I'm satisfied and amazed by this little thing.

Safety of replacement batteries

I'm looking for a replacement battery for my S4. Since it's replacement it doesn't have to be as good. What scares me though is that those cheap ebay/dealextreme batteries might hurt my phone somehow (those golden batteries etc). Is this possible, or is it safe to use those 'fake' batteries?
Also I would love if you guys could recommend a decent replacement battery for a good price (even better with a wall battery charger).

ZeroLemon will be doing a regular sized battery as well which is what i'm waiting for. And ZeroLemon are known for their reliability (and actually being 3000 mAh). I wouldn't trust the ebay ones.

i got one of this to test and it was the perfect replacement battery. So just ordered this from amazon expecting delivery right about now...

After some research I came to a conclusion I want that one too. Can you check if it's just the same size as the original battery? As I've seen some Anker batteries which were good but slightly too large.

the one i tested was non nfc, these are nfc enabled but i doubt that would make them that much bigger to bulge, but ill let you know as soon as this UPS man arrives at my office, gotta love amazon prime! :laugh:

I bought the Anker batteries. Get 2 batteries and a wall charger. The wall charger also has a USB port which can output 1A, which it pretty good to carry around if needed. I've read reviews how when these first came out it was a really tight fit, but it seems that they made adjustments because the ones I received fit in just fine, like the OEM ones.

Being that I dont have 10 post I can't post urls this is

Title-3X Battery for Samsung Galaxy SIV S4 GT-i9500 with External Charger 3250 mAh

worth it
I almost always buy the cheapo chinese batteries for my phones. Here are my findings:
They will last throughout the day about as long as genuine batteries... for the 1st year
After the 1st year, they will start to degrade.... depending on your use, lack of use, temperature, etc... I have some 2.5 year old chinese epic 4g batteries that still work.. but only last about 4 hours. My original battery will still go a good 12hrs. I only keep them around for emergencies, but I don't really use that phone anymore.
The cheapo chargers that come w/ it is very handy and usually work pretty well.
Depending on how much you use them, they will last you a couple years.
Why i think they are worth it:
For ten bucks, they are a great backup battery. By that I mean, when get home from work and my battery is almost dead.... I can swap out the battery for the rest of the evening and don't have to put my phone on the charger till bed.
I'm a normal smart phone user, a normal batter will last me the day most days. I don't game or do too many intensive things..
I get them because I know that I will get a new phone every 1.5 to 2 years... so why do my batteries need to outlast the phone?
Who shouldn't use them:
People who really drain their batteries. They simply won't go as many recharge cycles as a normal battery (by that I mean full empty to full charge).
Tips:
Mark your crappy batteries with a permanent marker. The chinese clones look so good that you probably can't tell the difference between them and a real on. Mark the fake ones so that you can use your real on days when you know you really need lasting power. This isn't so important the first 9 months... but after that it could be.
Watch for reviews on a good battery seller (if buying from ebay)... there are good cheap-o batteries and their are crappy ones. I like to let other people figure it out

Pocketable power bank charging at 3A?

I've looked around with no luck. Considering that most of the "lipstick" ones must have a regular 18650 battery inside, the 3A output is *amply* inside the range of good batteries output (several manufacturers offer 18650 batteries capable of constant 10A output with 3.500mAh capacity, I hope that there are products like this.
Thank for the help.

There aren't many. Your best bet is the one that tronsmart makes. It's available from Amazon for 30 bucks.
I ended up going with the ravpower 20,100mah USB c bank, it sorta fits in my pocket.

I suppose you are referring to this: http://www.tronsmart.com/products/tronsmart-presto-10400
While interesting is different from what I'm seeking. 6p has got a 3.500mAh battery, I would be good with a power bank worth one full charge. I come from a Note 3 and I always went out with a spare battery in my bag. Weight was less than 100g and size... well it's a Note 3 battery, I think the idea is clear. Now the "lipstick" shaped power banks are the right size and given their capacity it's obvious they have a 18650 inside... but I can't find any supporting USB C fast charging (5V/3A).

This seems interesting, too bad it's not buyable anywhere at the moment (not that I can find, I'm in Europe).

^That looks cool...

Yes it does. To be honest I'm surprised at the dearth of products on offer that support USB-C fast charging. It's been adopted on enough phones that I was expecting something more in the sub 10,000mAh range. Bringing a 10,000mAh with you is beyond the scope of even heavy phone use on a daily basis. Whereas I can see myself needing to top up at most one full charge during a day. For that, considering the loss due to efficiency, a 4,000mAh power bank would be enough for Nexus and other phones.
Let's hope that this LeEco power bank comes to US/Europe soon (or at least to websites such as GearBest and GeekBuying).
The official product webpage: http://cn.lemall.com/product/products-pid-1001514.html

I can recommend the ORICO 10000mAh usb-c battery pack.
It's not 3A, but 2.4A, however it still charges my Nexus 6P in about 1h 30m.
The good thing is that it supports charging two devices at the same time (one over the usb-c, and one over the standard usb port).
It also looks great, it's worth checking out.
I think there's a review of it here on xda.

AUKEY 5000mah small 2.1 amps charging. can carry in dress pants pocket with cable rubberbanded to charger. I have taken longer air flights with this little guy rubber banded to my 6p to watch videos for hours and hours. this has been a winner for me. $12.99 with prime

So absolutely not what the OP was asking about then?
To the question actually asked, unless you can fit this beast in one of your pockets, I'm pretty sure there's nothing out there that will meet your needs..
https://www.amazon.com/Anker-PowerC...8&qid=1481511899&sr=8-4&keywords=anker+type+c

after having this phone for about a year, the battery health has gone down so that it is almost always dead by 7-8pm now.. and carrying around a battery has become absolutely necessary in case I go out for dinner or drinks w/ friends after work...
when I have my bag w/ me.. the Orico is fine but when I'm going out w/ just a jacket.. I would like a smaller lipstick sized solution too..
Its frustrating that even after a year (and now w/ launches of the Pixels), its still so hard to find USB-C accessories :-/

Ever seen this one? It's size is manageable, it's a GMYLE 10000mAh and has a micro USB in, just in case you don't have a type C cable around

Thanks, but I really would like something that took the 18650 battery form factor and built a charger around it. I know their capacity, I know they are more than enough for whatever need I might have. Once I have a full charge with me I'm set. Unfortunately I'm not finding it... I might even accept to forfeit the USB C fast charging capacity if there was one...

I use this one and I love it. Also has a nice extra usb port so you can charge your 6P alongside another device, or charge a device while the battery pack charges. I get probably 3 full charges out of it.
https://www.amazon.com/gp/product/B01A6HKP7E/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

Single 18650 requires voltage step up and won't fill the battery,biggest 18650 I've seen is 3400 mah. That is about the size of 6p battery but its not a 100% efficient process. You lose some from the step up to 5 volts and lose some to heat and some to resistance of connectors and cable.

http://www.ebay.com/itm/262640284381 ?

I use and love the aukey one. I think is around 15000mah. It's nice and slim. And it charges faster than my 3a car charger from aukey lol

Check out this one here. Although the Ebay website's description is incomplete, other websites clearly indicate the Aukey PB-Y5 is capable of 5V-3A output. Looks like the ticket for one full charge. Unfortunately they are not shipped from the US yet so I will wait. Credit goes to MrTemz.

This one works rather well for me. The US link to the same company mentioned above.

Oh man, THANK YOU. Even better ('cause it saves me a little money), I found the AUKEY PB-Y8 which is only for USB Type C. In Europe, Amazon carries it: https://www.amazon.co.uk/d/Cell-Pho...-Input-Output-Cable-Devices-Nexus/B01M0UEMYV/ (not only for UK). Thank you so much!

Looking for a good new battery

Guys, my note 4 is almost 2years now, my battery is getting old, and may be it's time to buy a new one, because i intend to go on with this wonderful Note 4.
So, which new battery should i look for? OEM? Some special brand? My goal is to avoid those fake pseudo Samsung batteries, and pay what it costs for a really good one.
What's your opinion?
Sent from this galaxy
EDIT. What about Anker or Zerolemon? Are these better than Oem?

I recently bought a battery for my note 4 as well. To avoid any issues I went to the samsung service center and ordered it from there. I suggest that you check the official online store of Samsung.

I bought the Anker 2-pack with travel charger from amazon. They're holding up pretty well. I've bought Anker for my other phones as well and have never had any issues with their product.

They're talking about a 2-pack of internal after market (non-Samsung) batteries. Anker is a good brand, as far as I've seen.

Here,take those ones.My opinion is that this are the best ones.Not cheap but long live,good for using.https://www.amazon.de/original-JuBaTec-Akku-Samsung-SM-N910F-EBBN910BB/dp/B00UMMHG76

If you don't mind your phone being a brick, try using Zerolemon or Hyperion? If you use Zerolemon you might need a kernel fix though!

I killed my Note 4 battery by using a cheap eBay Qi receiver. Charging made it very hot, and the battery swelled and died.
I bought two replacements, both supposedly Samsung OEM batteries. I got one from Sprint, and another from Amazon. They look identical, but the one from Amazon is almost certainly a cheap clone. It doesn't hold a charge as well as the one I got from Sprint, which is probably the true OEM.
By the way, I switched to the Samsung OEM Qi wireless charging cover, and now it charges fine with no heating up. If you want to go wireless charging, I strongly recommend avoiding the cheap crap.

I've been buying Anker batteries for my S3, Note 3 and now Note 4 and I recommend them. Solid and reliable and if you have any issues, Anker are great to deal with.

ANKER for sure. Equal or better than OEM quality, and you really don't want to mess with low quality batteries. Be careful of supposed OEM batteries on ebay or Amazon, many are counterfeit.

This is the first time I've been disappointed by Anker. Bought a 2pk a while ago. They barely fit in the phone and kept popping out of their charger too. They sent me a replacement and they weren't much better. I pulled the bottom plastic piece off, scraped off the black adhesive and glued the bottom piece back on. Fit better. Still kept the old ones too. Rotated them all. Used a rubber band to keep the first two in the charger. Well they all pretty much started to bulge. Some worse than the others. I gave up on them. I have Anker batteries for 3 different phones, and these are clearly inferior in basic build quality to them. So I abandoned them.
Went with the Akku Polarcell. I also have a new OEM battery. After about 3 months of rotating the two, I feel ilke the Akku last a little longer than the OEM. Purely perception. I don't have the time nor inclination to test them properly. But here's someone else's review on here: Polarcell Review

Wireless charging
So using an aftermarket wireless charger is likely to kill the battery quickly?

Don't think so. I've been using a Choetech wireless charger for 18 months with no problems. As long as the charger and receiver are Qi compatible there shouldn't be any problems. What will kill your battery is using wired charging with fast charging enabled all the time.
