I think these are popular for battery-operated Blink cameras because they meet that criteria (including the voltage sensitivity), though Blink says not to use rechargeables.
Generally speaking, a high-quality NiMH like Eneloop is going to be a more cost-effective purchase. You don't need these in your TV remote.
Community Reviews
These USB C lithium AA rechargeables stand out for devices that need a steady 1.5 volt supply, especially Blink cameras and other voltage sensitive gear. The constant voltage can make low battery behavior more predictable and avoid the false low warnings common with NiMH cells. They also get praise for strong output in some high drain uses. The main knocks are misleading capacity claims, slower charging than hoped, and uncertain longevity, with some reports of sudden cutoff and weak USB output. A niche pick for the right device.
Common Questions (4)
Yes. They hold a steady 1.5V, which makes Blink low-battery behavior more predictable than 1.2V NiMH cells. In Blink doorbells and cameras, they can avoid the constant low-battery warning seen with NiMH, but they may still drop off suddenly when depleted.
3600mWh at 1.5V works out to about 2400mAh, so the listing's number can look larger than a typical mAh rating. That puts them in the same general energy range as good NiMH AAs, though the higher voltage can help in voltage-sensitive devices.
They can work in high-drain devices, but runtime and punch may be less impressive than other lithium AA brands. One use case reported was Quest 3 VR controllers, where they lasted about 5 months and gave roughly 10 minutes of warning at low battery.
No. The USB-C connection is for charging only, and the battery itself does not act as a USB power source.

These would be a cheap way to find out about this chemistry. Do some homework.
Emphasis on CHEAP. Since it's a new chemistry no one REALLY knows how long they will last.
I've got some Tenavolt Li that are 4+ years old that are still doing fine. But, they aren't the cheap ones.
I do have some HW Li, but NOT the USB version. Only had them maybe 6 months, so don't know longevity.
False capacity claims are a hallmark of this kind of battery. 70-80% of claimed capacity seems to be in the usual ballpark.
They do NOT have the claimed capacity. > 1768 to 2010 mAh
There is a trade-off of less capacity while USB charging vs proprietary charger.
This capacity review is worth checking out.
