..try give it 5-5.2V on one of the 5V pins, off e.g. a 4 cell
"4.8V" NiMh or NiCd battery, charged up to no more than 5.2V.


..beware that both "4.8V" NiMh and NiCd 4 cell batteries can be
charged up beyond 5.3V, so you wanna discharge your battery to
5.2V or use a voltage regulator between your battery and your
RPi4, to protect your RPi4.


..by all means stay below 5.25V (or whatever it is on the RPi4)
on those 5V pins, or you might burn up your RPi4.

Scenarios always come in sets of three:
best case, worst case, and just in case.
