Review: Potente, Robusto, molto pesante - Sono stati squisiti nel sostituirmi il prodotto, che per quanto robusto e potente di ricarica, era troppo pesante per me.

### ⭐⭐⭐⭐⭐ Potente, Robusto, molto pesante

Sono stati squisiti nel sostituirmi il prodotto, che per quanto robusto e potente di ricarica, era troppo pesante per me.

### ⭐⭐⭐⭐⭐ Ofrece una magnifica reserva de energia
*by M***Z on 14 July 2023*

En general muy satisfecho con el producto, ta un amplio margen de uso con la dashcam, con la que frecuentemente la uso en modo vigilancia o para cargar dispositivos. La única pega, que el tiempo para cargarla es muy elevado, eso que la estoy cargando con un cargador potente de 120 W.
