Good value starter kit
Good value starter kit to get into the Eneloop ecosystem. The charger is "smart" which ensures it doesn't overcharge batteries, among other features. Eneloop batteries are widely considered the absolute best for rechargeable batteries. Note that the black Pro batteries have a higher capacity than the standard white batteries, but cannot be charged as many times.

AAAs fall out too easily
Advertised as a portable battery bank, I find it is not portable. As the four AAA batteries become dislodged at the slightest tap. May be ok as a desktop charger, but that is not how this is marketed. The sliding door does not secure the AAAs. Maybe a spacer is needed to insert on top of the AAAs to keep them from being dislodged at the top (positive) terminal. Also the negative terminal is very minimal. Wish it had a sliding terminal like other charger brands.

Me encantó que es multifunción, el cargador incluye un cable USB a micro USB, puedes utilizar el cargador de tu celular, tu laptop, power bank etc. para conectar el cable a su puerto micro USB y recargar las baterías incluídas (ADVERTENCIA sólo puede cargar baterias recargables), la recarga va de 1 batería a 4, y puede ser AA y AAA, el tiempo de carga llega a variar dependiendo de las pilas, pero no es nada lento a comparación de otros de la misma marca. Digo que es multifunción ya que puedes cargar tu celular, ya sea con baterias recargables que vienen en el empaque con el cargador (Eneloop Pro) o algún tipo de pila desechables (alcalinas), cualquier batería servirá para cargar tu teléfono o cualquier otro dispositivo USB, sólo apretando un botón y conectando el cable en su puerto USB de salida. El tamaño es pequeño pero es muy práctico, sólo le veo un detalle, creo que hay que cuidarlo más que a los otros cargadores, ya que la cubierta deslizable se ve ligeramente frágil, pero está hecho de una excelente calidad. Recomendado al 100% es el mejor cargador que tengo hasta el momento.

I initially brought it because of the charging capability to charge 4 batteries at a time. But i was really sold when i start to bring it around with me and to charge my phone whenever I'm low on my battery. Overall if you want to use the portable charging capability, just treat it as a last min resort or emergency whenever you are unable to find a charging area instead of relying heavily on it for your daily needs.

Me gusta que puede usarse como respaldo, ya sea con pilas recargables o pilas alcalinas (No recarga pilas alcalinas!). Sin embargo es medio latoso por que no acepta todas las marcas de pilas, a veces, aun con pilas recargables nuevas, manda mensaje de error, siendo estas de otra marca. Es relativamente rapido para cargar las pilas. Lo recomiendo a secas....

I'm surprised at how light it is, although it does make it feel cheaply made. It works well so far. May update this review after I've done 1 full charge cycle. It's quite pricey but I'm happy with it so far.
