I found the 'Goldilocks' of travel chargers, and I don't travel without it (plus it's on sale)
Even when traveling with a laptop, I find that a 65W travel charger is the ultimate sweet spot, offering plenty of power without the bulk and weight.
Finally, I found a wireless charger for my iPhone with a built-in fan and Qi2 support
Wireless chargers are known for their predisposition to generate heat during charging. The Torras PolarCircle solves this problem - and solves it well.
