Power bank keepalive options

Hi,

I have a few power banks for various electronics, including recorders and my iphones. I've noticed that the power banks will stop supplying power to the iphone to charge it after ~90 seconds. The power banks I have been using are inexpensive ones, about $10-$20, so they don't have different modes to cycle through. It's quite annoying having the power bank connected to your phone and to have the battery on the phone drain so low. What's the purpose of keeping it connected?

It seems this is a known design (for me it's a flaw ;) ) but there are inline devices you can use to keep the power active and to charge the device.
Do any of ya'll have experience with these devices? Here's ones in particular:

If you don't have this issue, what specific power banks are you using? I don't seem to have the problem if I've actively using my iphone - it's charge it. But that's not practical if i want to charge up overnight or something.

I don't think this would be an issue on most recorders, as they're drawing power power than an iphone at rest, but that's just a guess on my part.

Open to hear from ya'll.

Thanks!

I've never had an issue with Anker battery packs and I've owned around 10 or so. Some of the Talentcell batteries have USB output and double as a 9v/12v battery for taping rigs (which is great IMO).

Thank you!

Talentcell or some other battery that features a good-ole toggling on/off switch rather than a momentary push-button.

I found a solution with my iphone until i get a Talentcell or Anker - play a podcast at zero volume (unless you want to hear it) and lock the screen. That will keep the battery out of its sleep state to change my iphone.
