¿Cuánto tiempo tarda en recargarse un Power bank? ⌚

El tiempo de carga de un power bank dependerá del cargador y cable utilizado, así como de las propias especificaciones del power bank.

También, otro factor que influye es la eficiencia energética del proceso de recarga, es decir:

Para conseguir una recarga completa del power bank, cualquier cargador siempre suministrará más energía de la almacenada en la batería interna del power bank.

Este exceso de energía, manifestado en forma de calor, dependerá de la calidad del cable empleado y del circuito interno del power bank que gestiona el proceso de carga de la batería.

La eficiencia energética en la recarga de un power bank se puede expresar mediante la siguiente fórmula:

Eficiencia Recarga = (Energía almacenada Power bank / Energía suministrada Cargador) x 100

En nuestras pruebas realizadas comprobamos que la eficiencia media en el proceso de Recarga Estándar (5V) de un power bank era del 85%. Esto quiere decir que el cargador debe suministrar un 15% más de energía de la que almacena la batería interna del power bank.

Con esta información, podemos utilizar la siguiente fórmula para estimar el tiempo mínimo requerido para poder recargar completamente un power bank:

Tiempo mín. de carga = [Energía Power bank (Wh) / Potencia máx. entrada (W)] x Eficiencia

Además, para poder usar esta fórmula se deben tener en cuenta las siguientes consideraciones:

  1. El power bank carga de forma constante a la potencia máxima indicada en el puerto de entrada USB.
  2. Se utiliza un cargador que suministra esa potencia.
  3. La eficiencia del proceso de recarga es del 85% (multiplicar por 1,15).

Lógicamente, un power bank no se recarga a una potencia constante ni tampoco es posible conocer la eficiencia energética cuando se recarga, pero usando esta fórmula nos permite conocer de antemano el tiempo de carga estimado.

Por ejemplo, si estamos interesados en comprar un power bank de gran capacidad, por ejemplo de 20000 mAh, y hemos visto 3 modelos con un precio similar, podemos utilizar esta fórmula para decantarnos por el modelo que se cargue más rápido:

Modelos Potencia máx. entrada Tiempo mínimo de carga
PB01 5 W (74 Wh / 5 W) x 1,15 = 17 h
PB02 10 W (74 Wh / 10 W) x 1,15 = 8,5 h
PB03 18 W (74 Wh / 18 W) x 1,15 = 4,7 h

Finalmente, en la siguiente tabla podemos ver datos reales del tiempo y la eficiencia del proceso de carga de algunos modelos analizados por nuestro equipo, tanto carga estándar como rápida:
