Battery bank turns on and off randomly

I bought this little patriot fuel active 2600mah charger on sale on Black Friday hoping to keep it in my backpack as a quick top up for my Nexus 6p, which often dies about an hour before I finish my day. Today, I was charging my phone while at my desk from 0% and I as it got to around 67% the charger turned off. This was to be expected as 2600mah isn't nearly enough to fully charge the 6p but weirdly, it started charging again a couple of seconds afterwards, then turned off after another couple of seconds. It did this a couple of times before I unplugged it. Is this normal? I'm not really sure what's happening. The box said the battery has safeguards against undercharging so could it be that? I don't mind it cutting out, but what worried me the cycling, and how it might affect my phone. Any help is appreciated, thanks!

Possible options:

 

a) working as intended due to interval charging do be nicer to the phone battery

b) protection circuit jumping in, meaning phone is drawing too much energy and this turning off is a safety thing

c) power bank broken, or dunno ;)

Anghammarad : Asrock Taichi x570, AMD Ryzen 7 5800X @4900 MHz. 32 GB DDR4 3600, some NVME SSDs, Gainward Phoenix RTX 3070TI

I'm trying to be optimistic, it charged normally until the end so ... option b? the battery is low and the phone is drawing too much?

or option a... 

 

There are some powerbanks that have this "intelligent" charging... not to stress the phones battery by not going "I GOT JUICE! DRINK IT UP YOU SON OF A DURACELL DOUBLE AA BATTERY!!!"

Haha, but would it be on or off within seconds... it seems too fast, then again i dunno too much. Also this is a really really basic powerbank so it might not have this feature.
