I think the reason most go for the Talentcell is because it has a physical ON switch rather than any sort of smart functionality based in software to enable power delivery or not. Most powerbanks can go into a sort of idles or sleep mode which could turn off the proton pack unexpectedly. There are, however, little gizmos you can get to trick powerbanks into always remaining on although I don’t have any links to any right now. The capacity has no relevance to the output which will be 5v although technically the pack expects 6v (4 x 1.5v batteries) so Frutto technology have created a little buck converter which sits in between the battery and the pack to ensure it has full power. https://www.etsy.com/uk/listing/1765609211/talentcellpowerbank-booster-for-haslab
Edit: Looks like I have a slightly older version, the current model he sells has smaller components now so it’s a little more compact than mine. Same thing though.
So, let me get this straight: if I buy the Xiaomi powerbank, I will need a separate device to keep the powerbank alive AND another device to adjust its voltage to 6V, is this correct?
This is all apart from getting a keep alive mod for the pack itself, right?
Hey, not sure where you’re located but I should mention that Talentcell isn’t available here in Australia either (occasionally they show up on Amazon AU but they’re usually HUNDREDs of dollars, although there seems to be some cheaper ones right now which is unusual).
However, I found Talentcell clones which have worked perfectly for me across two builds and have (so far) lasted 4 years.
They definitely sell the 10,000mAh version but this particular seller is out of stock right now.
They may not have USB output so if that’s what you need, you’d need a 12V to 5V USB DC converter, but those are easy to find (they’re used in cars). This might give you some ideas of some keywords you can search for (eg “for LED strips” and “CCTV”).
These powerbanks don’t have the keep-alive issue that USB phone chargers have. The switch is either on or off.
