I have the Zanflare C4. Its can do pretty much everything and is based on the Liitokala Lii-500 iirc. (Liitokala is a very well regarded charger brand.) Here is a comprehensive review of the C4.
But it is pretty bulky and all the features can be overwhelming if you aren't looking for something like that. Being able to quickly measure a battery's health by its internal resistance is pretty handy though.
Man that's crazy. I'm not familiar with that fast charger, but I've been using a good old BQ-CC17 at least a couple times a week since 2014 without issue. This package is a great value imo: https://smile.amazon.com/dp/B00JHKSMJU/
I'm sure you do?, but If you buy any electronics via Amazon, always make sure it says "sold by Amazon" as actual seller because any fake, refurbished, returned items are generally gonna come from third party sellers. Since Eneloop batteries are legendary, I'm guessing they're the most counterfeited battery in the world, and you have a far greater chance of running into fake batteries than chargers.
That said, genuine chargers obviously can have defects, but to get two in a row would be surprising. Others would know better than me, but although you shouldn't really have issues with any Panasonic charger, fast chargers might be more susceptible to issues than slower ones. Just my theory, could be totally wrong.
If you still have the actual cells, definitely look up the resource from OP on spotting fakes and/or post photos here if you want others to help. The odds of 8 defective genuine Eneloop cells seems like it would be very low, but who knows. Again, maybe go back and see if it tells you who the seller was on those. All I can say is I've bought Eneloops on Amazon since 2011 multiple, multiple times literally without a since cell going bad. I'm still using the batteries I bought in 2011 right now. I buy most of my camera and computer stuff from B&H Photo in New York, and I haven't looked at their battery prices lately, but I trust them way more than Amazon.
Yes, wall mounted. I found the organizers on Amazon, see here. The testers are useful. I've had no problems with batteries falling out, and this is in a room with a heavy door to the garage that gets opened and closed daily. No lids on these units.
> however i dont know what kind of plug the charger uses and the diameter to search online.
It looks like a common 5.5mm (OD) 2.1mm (ID) barrel plug.
Most 12V devices will run fine directly connected to a car supply. But the voltage can get as high as 14V. If you are concerned about this (or just want to run even more devices) consider getting a universal adapter.
what I'm asking for is something like this, but takes AA/AA and for keyboards with detachable cables or wireless rechargeable keyboards.
There are a lot of backlit wireless keyboards with lithium batteries so why not AA/AAA?
And if I end up making the adapter myself, I have a bunch of eneloop rechargeables lying around as spares so power is not a problem, and who doesn't have at least a box of alkaline batteries in their house?
I owned 12 of those AAs and 4 D cells about 20 years ago. I used them for the transmitter and receiver in my RC boat at the time. I still have the charger for them actually. It's called the Rayovac 3 in 1 model number PS3. They have been discontinued for a long time now. Many users at the time complained of leaks, and significant capacity loss after each charge. But I kept mine topped up after each run and they worked great for me for several years. Rechargeable alkaline cells are still produced by other companies. But at this point low self discharge NiMh are so good, I can't think of many cases where you would want to use them.
This new xtar 1.5V AA Battery with indicator for your reference: https://www.amazon.com/XTAR-Lithium-Rechargeable-Low-Voltage-Indication/dp/B0B27JQKPR?th=1
Just FYI, new release from EBL, can do 12 AA/AAA or 6 C/D. Direct AC cord input. https://www.amazon.com/gp/product/B08HRZJ2BY/
In general I think Tenergy is a little better, but EBL is pretty close, and that's a nice feature set. Maha is a step up in quality and the only one I've seen with a 8 C or D capability with the MH-C808M ($100 or so).
This is what I use LCD Display Universal Battery Charger, ISDT N8 8-Slot Speedy Smart Battery Fast Charger for Rechargeable Batteries AA AAA Li-lon LiHv Ni-MH Ni-Cd LiFePO4 https://www.amazon.com/dp/B07YG29YDC/ref=cm_sw_r_cp_api_i_STYTRQPGFXWNX77MR0C5
Don't limit yourself to chargers with usb c. There is a much better selection of chargers that run on 12V. Instead get a 12V usb c cable for a 12V charger.
With a decent charger, you'll get many years of life out of those batteries. I use mostly AA that are Li-Ion with micro usb charge port now, but I still have some NiMh used in controllers that are 10 years old. These things have been through many cycles.
I use this charger:

Yeah if I didn't have any panels over 20 watts, I'd keep my eye on something around 100w and see what goes on sale Black Friday. Building a kit is fine, but portable power station prices even with Lifepo4 batteries have come down to the point where for me it's almost a no-brainer to pick them up for emergencies and gifts. After seeing what happened in Texas and other places recently, I would get one even before investing in a panel for it and charge it from the wall just to have on hand.
This little guy was my first Lifepo4 and it's come in super handy: GOLABS Portable Power Station, 299Wh LiFePO4 Battery Backup, https://www.amazon.com/dp/B08P5SFV4D/
I bought a larger Lifepo4 station after this that will run a portable fridge, but this thing is so light and portable it gets used way more. I throw a couple panels outside and run extension cord through the doggy door and charge it every few weeks then charge all my little power banks and batteries off this. Funny enough they claim 10 year battery life before going to 80% and 2,000 cycles, similar to Eneloop, haha. We'll see.
For 37.5 cents more per battery you can get genuine Eneloops, which are LSD. I regularly get 2200mAh out of my AA eneloops.
Yeah I'm mainly using it via USB at home but awesome to have AA option--as I mentioned it was only one I saw like this that takes AA. Was $13 on Amazon https://smile.amazon.com/dp/B00YU0W3CY/
All the other cheap similar fans I have like Holmes and O2air are either non-replaceable 18650 batteries or need C or D cells. They do all push a lot more air than this, but are pretty noisy and tend to rattle. This one is cheap no doubt, but quieter, more versatile, and feels like better quality.
If you're new to batteries, this might help:
Imagine a battery is a tank of water (electricity being the water). mAh is how much water the tank holds. Amperage is how big the drainage pipe is. Voltage is how fast the water is flowing through the drainage pipe.
Eneloop Pro AAA's with a charger are the same price as what you linked to, while having 300 more mAh (900 mAh total). Eneloops are also the golden standard of rechargeable batteries. If you want to read up on why; Eneloop101.com has all the info you could ever need. I personally use them in everything I own and they've paid for themselves many times over with their reliable leak-free operation. Hope this helps!
I don't use noise reduction. Still trying to figure out how to get the maximum playing time when listening at "normal" volume (probably 60-70%). I was looking at batteries like these but they may not last long per charge?
Their chargers are only cost-effective when bundled with batteries. Plenty of other choices for good NiMH chargers. Nitecore D2 for example.
Here is the exact listing. Just used the "buy now" button, didn't pick a specific sell or anything. Also, the eneloop101 website has instructions for checking if you got legit Eneloops

Excerpt:
> Amazon offers the Panasonic eneloop Power Pack with charger, 8 AA and 4 AAA rechargeable batteries for $34.99 shipped. Also at B&H. As a comparison, it typically goes for upwards of $50 with today’s deal being the best we’ve tracked at Amazon in years and a match of our previous mention. Panasonic’s eneloops are a must-have for any tech-laden setup. This bundle includes 12 batteries and a quick charger.
The quick charger is nice to have, but to maximize battery life, this is better:
If you already have the standard charger, it might be a good time to add a quick charger to your inventory.
Just wanted to check in to see if that wall charger (Panasonic K-KJ17MCA4BA) on Amazon is still the best wall charger. I've been reading up on the subreddit the past few days and it seems like if I want to make the jump to the eneloops, I should be buying 2 of those wall charger packs (8 batteries, 2 chargers) for ~$35 on Amazon. On the amazon page you linked, there are "quick chargers" and "standard chargers." Did you pick the standard chargers over the "fast charger" on purpose? I think I have read for phones that not enabling "fast charging" helps the battery life over the lifetime of the phone. I'm not sure if that's kind of the same idea.
Is that same amazon page you linked for the charging pack the best place to get the larger battery-only packs for AA and AAA? In other words, 12/16/24 packs? Also, is there any way to ensure you are getting the 2019 - 2020 battery packs (from the "eneloop 101" link)
I bought one of these eneloop pros from amazon about two years ago. I had to throw away one of the batteries because the charger stopped charging it, but other than that, they are still fine. I do remember reading one of your posts saying that some wall charger discharges the batteries a certain amount per hour they are left in it (i.e. remove the batteries as soon as you see they are done charging). Do you know if the eneloop chargers are smart enough to leave charging all night without them discharging?
I believe you also recommended battery caddies - this is the most popular one on Amazon currently but I don't know if it matters - I'm guessing the only reason is to have the batteries spaced out
I don't know if I need adapters for D cells... What is the best option for 9V batteries? Is it the energizer lithium? How about button cells like the CR2032 (car key batteries, tile pro batteries, etc.)? Thank you.
> I’m just putting them in some Xbox controllers man, charging time won’t matter when I get days of playing from one charge. I’m not trying to ultra maximize the longevity of my batteries for 10 years, I just want some decent rechargables that don’t cost a ton like some of these larger brands at the store. I’m not paying 20 bucks for 4 batts and no charger just to power some remotes. I can get 8 Amazon Basics and a charger for like 35 bucks and free shipping.
In that case, the $17.99 Eneloop package I recommended is the most economical deal. It comes with the good charger, and 4 AA Eneloop NiMH batteries. You can buy 16 more Eneloops for about $34 on the same page, but it's probably better to just buy 2 of the cheaper packages to get 2 chargers and 8 AA batteries. Here's the link again:
You won't save money with AmazonBasics, and your use case is actually ideal for Eneloops. If you do buy some AmazonBasics, you won't need any other charger because you can use the Eneloop charger is the best, and you can use it an any NiMH batteries, including AmazonBasics.
The Eneloop charger only adds about $6 to the cost of AA batteries. You can get 4 AA Eneloop NiMH batteries without a charger for $11.99 if I remember correctly, so if you only want 1 charger and 8 AA batteries at minimal cost, your total is $29.79, which is less than the $35 you're planning on spending for lower quality AmazonBasics.
Again, you won't save any money on AmazonBasics. You will pay more, and get less. That is all.
Interesting, especially for the price. Any thoughts on the cover that goes over the batteries as far as how durable and would it stay in place if the charger got moved around a lot in a backpack? I bought the similar Panasonic/Eneloop unit after someone posted about it here a couple months back, and the cover is flimsy and slides off way too easy or falls off the tracks completely with just a bump:
https://smile.amazon.com/dp/B07WTRGRCV/
As a charger, it works great and is faster than my regular Panasonic charger, but it's just not as portable as I hoped because of the cover since I always feel like it's gonna break in my backpack if it gets bumped. As a powerbank, it has even less output (1amp), but it does charge my phone.
If anyone is interested, only $10.99 on Amazon:
This is a good combo pack. Panasonic K-KJ17MCA4BA Advanced... https://www.amazon.com/dp/B00JHKSMJU?ref=ppx_pop_mob_ap_share
I’d recommend getting extras so you don’t have to wait on them charging.
Also these sleeves may serve you if you have C.

> Does eneloop make rechargeable Cs and DS or just spacers?
In general they're not as common. Apparently Amazon has some that claim 5000mAh and low self discharge.
This is pretty ridiculous looking and not AA, but maybe someone with more knowledge than me could make it work with AA batteries. I just remembered reading how to turn your QC25 headphones into Bluetooth headphones when phones started dropping the headphone jack. This adapter was in the article I read at the time but it's got a built-in battery.
>They're made in Japan
They are not anymore.

> AAA rather than AA (not quite perfect to the mantra of this sub), but the principle of it working on common enough batteries is there.
True, but AAA is AA-compatible, and thus AA Master Race approved. I will check it out. If I can find one that takes AA, obviously I will prefer that because it will last twice as long, but I do have a few AAA Eneloop NiMH batteries laying around I could use.
The best candidate I have found so far is this one that takes 4 AA batteries:
Of course, what I really want is AA battery wristwatch, but sometimes I want other people to be able to see the time in a room too, so something like the clock above would work, and it doesn't need to be near a power source.
Excerpt:
> With the NEBO Z Bug, a single button switch controls all the light functions — a spotlight when the unit is closed and a soft white light that will cast light over a small area, like a table top, when you extend the unit to its full height. > > Hit the button again and a blue ultraviolet bug-attracting light comes on with the white light and energizes the bug-zapping rails in the light. One more press of the switch turns off the white light but leaves the bug-attracting light and energized rails on to help rid the area of mosquitoes and any other flying bug. All this using only three AA batteries.
Just be mindful UV bug zappers aren't effective against mosquitoes (they're attracted to CO2), and UV light causes eye and skin damage, so you don't want it close to you, family, or pets while it's in UV mode. It works just as well when it's half a mile away, since it attracts flying bugs from long distances, so there's no need to keep it close to where you are. Just remember, if you can see it, it is hurting you.
More info:
They don't throw off a ton a light but definitely light your way.
Completely different, but a friend gave me one of these during a power out and it was super practical when you need a lot more light. The magnet part was very useful for hands free:
Evelots Compact Flashlight, Swivel Hook, Magnet Back W/ 27 LED Lights https://www.amazon.com/dp/B00NABPYDY/
The ones he had were yellow and he got them from a Harbor Freight store so they might even be cheaper there.
(sorry, I don't think they're AA, haha, but still cool for price)
