Great price on a widely available 2-channel charger.
With most people using batteries in pairs, the limitations of a 2-channel charger shouldn't be significant. However, note that you don't have to pay a million dollars more for a comparable 4-channel model (where each battery is recharged independently).
I have over 40 amazon basics rechargeables. Most garbage batteries ever. Low charge, quick drain etc no matter which model version. I wont waste a single penny on these ever
After spending a bunch of money trying out different brands of rechargeable batteries, I have decided to simply stop using them entirely. They all suck.
The biggest problem is that rechargeable AA batteries have a nominal voltage of 1.2v as opposed to 1.5v of a typical battery. For some devices this works fine, but I have simply run into too many instances were they don't work, or only work for a very short period of time. Some devices, for example, require six AAs. That would normally be 9v, but with 6 rechargeables it's only delivering 7.2v - the device powers on for a split second and shuts off again.
They also seem to lose quite a bit of charge when sitting idle.
I'm going back to waiting for the $0.25 per battery deals on normal AAs. Way less headache, they're actually full when you grab a new one, and I also don't have to worry about losing them.
I'm sure for other people it's different, but for me they're just not worth using.

Check out harbor freight's alkaline batteries, kevreviews has had excellent results from them.
the 2000mah batteries are MORE durable. it is the inner construction that matters, not the mah. you get more capacity and less durability an electronic geek told me concerning the Eneloops.
While that is true with AA/AAA NiMH batteries (and the spec you look for is 1000x recharge cycles vs 400x), in the Li-Ion world, the mAh has been increasing in the standard size (18650, 21700, etc). Though they don't report the number of recharge cycles in Li-Ion.
Feels like the 8 battery brick for $21 is a good deal even if the Amazon batteries are no good ?
I personally have never needed to charge more than 4 batteries at one time. Add to that, the IKEA charger 4-bay, 4-channel charger is a mere $7.
However, if you do have an application for charging more than four batteries at once and value the convenience of a single, USB-C based charger (rather than, say, using a couple of 4-bay chargers) then you might consider the Amazon option a good deal.

I bought a few rechargeable batteries but I stocked up on enough Energized batteries from Microcenter for the next 10 years lol

Only the high power output needs exactly the nominal 1.5V. They are only a few and in this case you should use the high power Li battery instead. The majority of devices will work fine with the rechargeable batteries.
I no longer recommend NiHH for most devices. The nominal 1.2V cells put you at a 20% disadvantage from the start. I have multiple devices that CAN use 1.2V but because the nominal voltage is already 0.3V below the required 1.5V, I have to recharge/replace very often.
Going to be diving into 1.5V Lithium cells for the holidays. We'll see ...

If you are ever willing to try again, lithium rechargeable batteries have higher voltages and perform better
Went back to check the support documentation and I think you're right. Basically, they never updated the product listing, which quotes rates for charging pairs of batteries. However, the PDF for the product does indeed suggest charging any number of batteries between 1 and 4.
While that is true with AA/AAA NiMH batteries (and the spec you look for is 1000x recharge cycles vs 400x), in the Li-Ion world, the mAh has been increasing in the standard size (18650, 21700, etc). Though they don't report the number of recharge cycles in Li-Ion.
Most companies advertise the estimated number of cycles based on a completely unrealistic standard. A newer standard, with slightly more realistic estimates is out but I haven't seen any manufacturer that plasters those numbers on the front of the package or advertising material. If they disclose it at all, it's usually in the fine print.
I consider 2000-2100mAh the sweet spot for NiMH AAs. Going higher, you sacrifice considerable overall lifespan, as well as some additional self-discharge. All of my 2100mAh (made in China) Rayovac Hybrid/Platinums from 2007-2011 are still limping along. Meanwhile, most of my 2500mAh (made in Japan) Eneloop XXs from 2012 are dead, despite generally having less use.

Oh I know that is the case for NiMHs, I was just pointing out the differences in advancements in the Li-Ion world.
For NiMHs if you haven't seen it, I consider the gold standard of cycle testing is aacycler.com, though it tends to be perhaps too stressful. It's what makes me skeptical that Ikea LADDAs are basically Eneloops. And you can see a very large variance for even modern LSD batteries in your 2000-2100 mAh sweet spot range.

In fact, IKEA has their model [ikea.com] widely available for $7.
Alternately, Costco has often sold a four-channel charger in starter kits (so with batteries) for under $20.
Good luck!

The charger in that example is a 8-battery, single-channel USB-C powered model (you have to supply the USB-C power brick).
Definitely a diffferent beast to the charger on offer here or something like the $7 IKEA model mentioned earlier.
Good luck!
