This isn’t about those batteries (doesn’t help that the battery link is first). It’s about the device.
I have one of those, too, although I use it for something else. My smart heating valve motors use 2 AA cells, but I’m fed up with having to change those all the time. Even once per year becomes a chore when you have one in each and every room. There are dummy replacements for AA cells that you can power from an USB power supply, but those valve motors need a button push after inserting the batteries (or after a power cut, with those adapters). This little cheap micro UPS solves that issue easily.
PS: Also, I get those batteries listed for 10,63€. On a cosmic scale that is approximately 1 Euro, sure…but it also is a bit on the expensive side.
The price of anything on Ali depends on the shipping destination. Please understand the links as examples. Nevertheless, should I delete it since my post seems to have been met with more disapproval than approval?
I wouldn’t go that far. Just drop the links to the batteries (those are trivial to source anyway) and put an image of the device top and centre.
It is one of the few micro UPSs that actually have a sensible price point. There are some in the $40 dollar range, but that’s often excessive and most of those only have a 12V output.
