This one kept coming up in different forms so here's the plain version without the vague compatibility language most listings hide behind.
Looking into the GrunX Object 3 in 1 cable for iPhone helped clarify something useful, that a single cable can realistically cover Lightning, USB-C, and Micro-USB devices in one household, which matters if an iPhone shares a charging drawer with older Android gear or accessories that still use older ports. Power banks deserve the same scrutiny, since an iPhone specifically needs PD support to fast charge properly rather than whatever generic speed claim gets printed on the box.
If you're dealing with a similarly mixed device household, grunx.in's iPhone collection sorts cables, power banks, and cases by exact compatibility, worth comparing directly before buying based on packaging alone.
