Power Bank
Power for playing while charging — but think of it together with heat.
What it changes
A run of ranked games outlasts the battery. But charging while playing adds heat, which ties straight back to the cooling entries above. Fast charging runs hottest, so if your phone lets you cap the charge rate, frames stay steadier with it capped during matches.
What to look at
Output (W), port count and pass-through matter more than raw capacity (mAh). If you also power a Peltier cooler from it, budget output for that too. Weight matters if you carry it. If you only play at home near an outlet, a plain charger is lighter and steadier.
