Typical results:
1880mAh @0.5A-81% of claimed capacity
1700mAh @1.0A-73%of claimed capacity
1575mAh @1.5A-68%of claimed capacity
1370mAh @2.0A-59%of claimed capacity
THIS MODEL DOES HAVE A VOLTAGE STEP DOWN.
It drops to ~1.1v for around 480mAh.
This allows SOME devices to notify the user that the voltage has dropped instead of cutting off abruptly like most of these kind of batteries.
MUCH longer time spent at 1.1v, at the expense of less time spent at 1.5v.
Voltage sensitive devices will see less capacity.
If you read the 3* reviews you'll see some people are getting what appear to be defective batteries. All mine work.....so far. Long term reliability and self-discharge are unknown.

The 1.1v plateau feels weird especially when it's trading off the time spent at 1.5v which is the whole point of buying these.
Get a $1 adapter. This is a non-issue.

You are plugging it into a usb-a at the wall outlet (or at least usb-a speeed @ 5v 2a). It's not going to charge any faster with the usb-c and last I checked that's still $4 cheaper than the one you mentioned. This is slickdeals not almostslickdeals.
https://www.amazon.com/Adapter-Co...07MV5NFCH/ That adapter will let you plug it into your usb-c chargers, power bank etc. The usb-c version of this charger is $28 (for the same manufacturer). https://www.amazon.com/HW-3500mWh...B0DHN

SinceHoly 3500mWh are decent getting ~85-90% of claimed at 0.5A. Short time used. No idea of long term reliability.
Dracutum 3000mWh.- on a percentage of claimed capacity this is one of the best ones I have reaching 90-95% at 0.5A draw. They sustain 70-73% at 2.5A which is pretty decent.
The Dracutum ALSO HAVE VOLTAGE DROP, to 1.1v. BUT, they only do that for ~50mAh, so there is a BRIEF notification window of low voltage, but little loss of working capacity. This is the first brand that I've owned that does this.
ALL of them were bought on some kind of special, usually ~ $2-2.50/cell. I would not buy these for $4-5/cell but I really don't NEED any of these, NiMh are fine for me most of the time.
I don't have a door lock or critter cam. Those things have an entirely different demand and usually DON'T do well on NiMh, or alkaline. So those folks end up with lithium primary like $2-2.50/battery for disposable.
For excellent rechargeable lithium AA, and willing to pay the price, look at the Xtar brand.
(Note-Cicnod and JWWYJ are both not too good. Imren are OK but only if bought cheaply.
If you are one of those people that HAS to have USB-direct charging, you WILL give up some capacity fo it. Not much room in that tiny can for chemicals AND electronics). I have not found any brand in AAA size that is even decent except Tenavolt. Just too tiny and the manufacturers routinely mess this up by making them USB-direct charge. Stupid. .
If you don't want to, fine.
FWIW I've got the means to test the resistance of USB cables. MOST of the cables of any sort that come with cheap devices have pretty high resistance. Doesn't matter if it's micro or C. C is no panacea except for being more user friendly...generally. For stuff that REALLY NEEDS C, and at HIGH amps, it's a different story. For that you NEED a really good cable.
NONE of these little chargers NEED high amps. The batteries couldn't take it anyway. Most are limited to 0.5A/battery, otherwise they'd get HOT. Charging control ISN'T the 'charger', it's INSIDE the battery. The 'charger' is simply 5v USB pass-through.

It's so very, very simple. I choose to not use micro usb on any new device I buy. It's not worth it to me to save literally $0 for the privilege of having to pull out an old cable to only use on this one device. Also, I'm not telling anyone not to buy this. Just expressed that it's a deal breaker for me and don't understand why that's an issue, to now, 2 of you.

My micro-USB is attached to the charger that I have to get out to charge the battery anyway.
