Good Quality and Quick Spare Battery Charger - General Accessories

I have an LG Lucid which isn't half bad. Unless you factor in battery life.
So I'm ready to pull the trigger on a spare battery or two, as well as a wall charger. You know those ones that you plug the battery into itself.
Anyone have recommendations on an inexpensive, decent charger that will charge a 1800-1900mah battery within maybe 6 hours or so?
Thanks!
Oh- looking on amazon if I can, as I have a gift card.

I just did this for my S3.
I can't recommend one for your phone, but once you know what to look for, it's the same basics across all batteries and chargers.
Do you want it to charge slowly ? You say 6 hours, but that seems awfully slow to me. Is that the point - so you can leave it on overnight ? I have a charger that chargers my 2200mAh battery in ~4 hours.
Look for a charger that will charge at 600+mAh. Often it will charge faster if connected to USB. You want to avoid the ones that charge as slowly as 300mAh. I guess they're good if you want to leave something overnight, but they're going to take ~8 hours to charge the battery !
Anyway - no matter if you want it to charge fast or slow, just look at the mAh output and do the math compared to your battery capacity - you can even use a "calculator" that will do the math for you (but it's really easy - "2200 / 600 = 3.6" - so 3.6 hours, but with some wiggle room for lower than 100% efficiency).
I got mine from the brand Anker - they were one of the few that offered a charger that wasn't ridiculously slow. It's 600mAh from an outlet, 1000mAh from USB (meaning it could charge the battery almost twice as fast). It came with two spares and the charger. All the reviews I read didn't say great things about the "universal" chargers, and they all seemed to have lower rates of charging - but maybe I wasn't looking at the right ones.

This chager charges my phone from 4% to %100 in exactly 3 hours.

So I just ordered this charger and it charged my phone from 4% to %100 percent in exactly 3 hours!

Wow, what a great improvement over stock which takes 6+ hours. This makes me believe, that even though the stock output is rated at 1000ma and this charger's output is only rated 700ma that this charges works correctly!
If you have a 1800mah battery and you charge it at a rate of .7A, it should take it exactly 2.57 hours to charge, (1800/700). With stock it should take less, because 1800/1000 = 1.8 hours, but it takes 6+ hours to fully charge! Something is f'ed up with the stock charger or phone's software...
Yeah. About that. I just got my E4GT yesterday and noticed it does charge extra slow compared to my O.G. Epic.
My wife stayed with hers, maybe I will try charging my phone on hers. I wonder if that would make a difference...

At first my charging was extremely slow but now it'll charge from 2 to 100 in under three hours

I use the Palm charger from my TouchPad. Will go from dead to fully charged in about an hour and a half.
What's you TouchPad charger's output in mah? I think I might have to splice into a spare USB cable and check how much current is actually used by phone when on stock charger...pretty sure it is nowhere close to 1000mah.
2000mah is the output from the TP charger.
According to BatteryMonitorWidget, it estimates avg mA charging at 270mA using the stock charger that came with this particular phone.
I have my original charger from my Evo 4g and have noticed that it charges my phone a lot faster then the stock one that came with the phone. :-( weird

That sounds about right! I'll see if I can test this with my AMP meter tonight and tell you all for sure on stock vs new samsung charger that I've got.

Yeah, at 2000mah it should charge in less than one hour...I would say your actual charge current to be around 1200mah...
i would be careful with these chargers.
i have dealt with a lot of Li-Po's in the past and there was a formula to how fast you should charge them.
i imagine it is the same deal with Li-On.
charging outside such formula could kill the life of your battery or worse.
Seems like i must have gotten lucky as a ton of people are having problems with their phone or chargers.
I just charged my battery from 0 to 100% off the stock charger in 2 and a half hours and i also havent gotten any of the dodgy input problems using the phone while charging.
I went back and took a longer look at the battery history when charging. When starting the charge at 65% it starts off around 828mA, then 540mA, then 360mA, so it looks like (as expected) the phone knows how much current to pull to charge the battery safely and it adjusts based on how full the battery is. Not saying it does this for the charger included with your phone, but that is the behavior for the charger included with this phone.
These are all estimates provided by Battery Monitor Widget because there is no real-time mA current meter in this phone (according to the author)
Ordered one of these. Stock charger takes a lifetime to charge the phone.
My GF got Nexus S 4G and it's stock charger also takes 6+ hours to charge, so there's something wrong with the chargers I guess...
The pins on this charger must me different than the stock charger. Just because the stock charger is rated up to 1Ah doesn't meant the phone or batteries circuitry allows that much output. The resistance and length of the USB pins on the cable are what determines the output of the charger. Simply using a different USB cable with the stock charger will get you faster charge times.
Using a 2Ah charger will get you nowhere, the circuitry doesn't allow that strong of a current. Just a bit of an FYI. Save your money and save your phone, use a different USB cable.
Also, how is the charge time holding up? I doubt you're getting a saturated charge with that charger.

Ive dealt with 1,2, and 3 cell lipos ranging from 150mah to 5000mah, and every one of them either say to be (or ive been told its recommended to do so) charged at 1C. so a 500mah battery should be charged at .5A, 1000mah at 1A, 5000mah at 5A, etc...
my lipo charger displays a bunch of info as the battery charges and it definitely drops the current as the battery gets closer to being fully charged. if its the same with li-on then I would imagine that .18A should be the most you would charge this battery, but Id rather it take a long time because unless things have changed recently, doesnt the slower you charge the battery prolong its life cycle as well as extend how long it lasts each charge? I only charge mine at night when I am sleeping so who cares if it takes longer than an hour. if I get into an emergency situation I have the cig lighter charger and in the worst case I even have one of those crank flashlights I can use to charge the phone in the event my car battery shorted out or something...

Has anyone had luck with external batteries?

A week or so ago I got a good deal on a nice solar charger, but was rather surprised at how ineffective it was at charging my Kindle Fire. The charger is basically a 4,000 mAh battery coupled with a 1.4 W solar panel, and puts out 1 A at 5.5 V. The Kindle, has a 4,400 mAh battery and can charge at up to 1.8 A (per the adapter), so I figured the two would be a good match.
Sadly, I only got about a +30% charge for the Kindle while depleting the charger. My first thought was that the 4,000 mAh charger battery really was too good to be true at that price, so I tested it with my phone's external battery charger, and got 2540 mAh of charge plus several hours of trickle charging between batteries.
Doing some research, lithium ion batteries have 80-90% charge/discharge efficiency, and charging efficiency is 97-99%. The charging circuits between the two batteries also must pull from these figures. So, 2,540 mAh and a fair bit of trickle charging seems reasonable for a 4,000 mAh battery to supply another battery. That's 80% minus 660 mAh of wasted charging/other inefficiencies.
Now, came the question of why my Kindle is getting less than half of that. Feeling that the charger was getting warm, I figure that the Kindle is taking advantage of the full amp offered, and perhaps more (I may have to catabolize some cables and rig up my multimeter to be sure). Furthermore, there is no way to charge the Kindle when it's powered off, so you get a constant drain from that (on AC power-management settings, no less).
To test that latter concept, I left my 95% charged Kindle on the charger last night, and it completely drained the charger in about 15 hours. This seems quite high for the power consumption of an idle device, but I'm sure it "thinks" it's on AC and there's little reason to conserve. Which explains why I'm getting such poor performance for my external charger. Or so I think...
All that said, does this mirror other people's experiences?

Charging the OP3

What is the optimal way to charge the OP3 in order to preserve the battery lifetime? I don't care about charging speed, I just want the battery to last long with minimal degradation. Is dash charging bad for the lifetime of the battery? Or would I be better off charging the OP3 slowly with a traditional charger? Right now I have this charger
https://www.amazon.com/gp/product/B00SZHOI8U/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
You should be using the OnePlus charger and cable which came with the phone. For optimal battery life, don't let the phone discharge below 10% and charge it till around 90%.
Dash Charging should be comparable with QuickCharge 3.0 which helps preserve battery life. So I reckon the official charger is your best bet.
Charging a battery with high intensity is bad for a battery life, dash charging/VOOC or quickcharge (any version) will be bad for battery in the long run.
But you'll only see a difference in 3 or 4 years and I don't think you'll use your phone more than 3 years. And even if you want to keep it more than 3 years, even if you don't use the phone, age will act on the battery. Even if you charge it slowly or quickly, there won't be a big difference in 2 years. Just be aware that USB-C cable have an active component in the cable head and a cheap USB-C cable can dammage your device.
If you still want to charge OP3 in good way, you have to plug it on a computer so it will charge at 5V 0.5A. It's very slow but it should charge your phone overnight and during the day, charge it while you have any occasion. 10 charge from 70% to 80% have less impact on the battery than 1 full charge from 0% to 100%.
Don't run it flat, keep it above 20-30% and don't fully charge it.
Don't leave it on charge overnight.
I run mine from about 30% to 90% maybe a little over as a 90% charge is what it takes to reset the days battery stats, screen on time etc.

External Battery Chargers That Work with Extended Batteries?

I have two of the 2X capacity batteries from Perfine with included case. They're a bargain at < $25US, but the challenge is finding an external charger that will charge the batteries when they are outside the phone. Most chargers are either those "slot" chargers that only fit the standard size battery. Some others inexplicably put the contacts on the opposite side of where the V20 puts it. You have to put the battery in upside down to fit., so the extended battery is too thick to reach the contacts. The standard battery fits fine, even thought it needs to go in upside down.
I did find one generic charger on Amazon that almost works. https://www.amazon.com/gp/product/B01JZLHTHG/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
The drawbacks to this charger are that it charges extremely slow, and it does not completely charge the battery to 100%. It finishes charging at about 95%, regardless of how long I leave it on the charger. I could probably deal with the slow charging, since it's for an extended battery that lasts upwards of 48 hours, but would love to find one that finishes strong with a 100% charge. It's the only one that will actually charge an extended battery, so I still find it useful, but I was wondering if anyone has found one that will at least charge an extended battery to 100% charge.
Anybody find a good candidate?
Thanks

Wall Charger 1Amp or 1.5

Hello guys,
To offert at my battery the best treatment I'm looking for a lower amperage wall charger for my Pixel 2XL.
Between 1 and 1.5 Amp it will be excellent. I read some interesting suties about battery life and how manage it and fast charge is part of that.
Thank you all anf have good evening.
I am sure it will charge on either one, but how fast who knows? If you are rooted and have Magisk, download the ACC module and you can control your charging that way instead.

Older USB chargers are mostly slow 1A chargers, like the cube Apple chargers

I am an electrical engineer, and have some knowledge about how Li batteries function.
I have always wondered this, I always see people mentioning that slower charging is better for the longevity of Li-ion batteries. There is always a trade-off here. Slower charging also means the battery takes much longer to charge, and the battery stays hotter for longer period of time, which should affect it's lifetime. Fast charging also does the same thing, but the temperature is much hotter but is exposed for shorter period of time.
Now these is merely a speculation on my part, I don't have any theoretical or experimental evidence to back this up - I think regular 5V 2A charging is a balance between those two scenarios.
Also, I recall that the peak charging current is limited in P2XL, so using the stock charger shouldn't harm that much either.
Pixel 2XL is my first smartphone who do not Come hot when it charge so...
But I know that high temperature are not the best things for battery in general.
And about the level of charge ? Some people said they stop at 80% to manage battery

I use a 5 watts charger and the phone stay completely cold during the charge process.
Also there was a recent 2017 scientific paper that tested what degraded the battery. It's a really interesting read with many tested model.
https://www.researchgate.net/profil...e-model-under-different-charging-stresses.pdf
Number 1 cause is high battery voltage at the end, second one is battery charging speed. Any speed faster than 1c will degrade the battery much faster.
This is why i charge at 5w plus stop charging at 80% (unless i know I'll need 100% that day, where i fully charge, but for my usage 80% is more than enough for the usual day).

I charge my phone every 48h and when it is full I unplug it from wall charger. And I charge it from 20-25% (some time I go lower because of my usage)
It's your famous amazon wall charger?

I download AccuBattery and charge my phone from 25% to 80% max. The app detect directly the stock capacity of my battery (3520mAh) but after my charge, the new capacity estimated is 2982%. Is the first value is reliable or I have to do some other charges?
You have to wait for about 10 cycles. It says in the application something like that.
