It doesn't warm up much, but it's enough. Tested on an old USB charger, but should heat up more on one with more amperage.

não aquece muito, mas é o suficiente. testado num carregador USB antigo, mas deve aquecer mais num com mais amperagem.

Connected to an old powerbank it heats slightly, slightly above lukewarm, but I believe it better connected to a USB port with more capacity. Anyway, it works.

ligado a um powerbank antigo aquece ligeiramente, um pouco acima de morno, mas acredito que melhore ligado a uma porta USB com mais capacidade. de qualquer forma, funciona.
