Are you sure though? I have one and whenever I charge both, using the pack as a wireless charger, things get piping hot. The same btw if you connect a full pack to a nearly dead phone…

Imagine what will happen with even poorer heat dissipation when stacking multiple of these…
hadn’t thought about that—will be interesting to see if Apple has anything particular up their sleeve for heat dissipation (yeah you can’t beat physics, but…wishful thinking I guess)
 
You can get multi-connector, high quality braided cables from Native Union, but they are expensive 😂
Cable is an expensive piece of junk. Connectors disconnect from cable making it impossible to charge your device. Had one cable replaced; wired the 2nd one together for charging android phone. Native Union will not honor warranty from Ebay even though they replaced one of 2 cables purchased new through Ebay. Horrible company. Look for the negative reviews on Amazon before you buy.
