Anker is an excellent brand for chargers, batteries, and accessories. So I trust I am getting quality components and can focus on specs. It is really nice that they keep coming with the latest fast charging technology (PowerIQ 2.0) and up to 18W output that will far exceed most phones (at least as of 2019). And it is all packed into a sleek little device shaped small and flat enough to go anywhere. This has 10,000 mAh capacity, which is a lot, considering an iPhone 11 has 3,110 mAh (and others range 1800-4000 with most being 3100 or less). I like that it is easy to check the battery level status too. And the button doesn't seem prone to getting accidentally turned on. It comes with a nice little pouch to carry it, its recharging cable, and any of your short phone charging cables to connect to it. This is one of the most optimal and worry-free balance of form, capacity, and weight in ordinary circumstances.
BATTERY CAPACITY = WEIGHT
You can put it in different shapes, but it still all weighs the same proportionally to the battery capacity (in mAh). So you really have to decide how much battery backup capacity do you want versus how much weight to you want to carry around? I have a little lightweight 1,000 mAh battery stick that seems to weigh nothing, and will give you some emergency power, but far from refueling your phone. This 10,000 mAh could refuel the same phone 3 times or more. And I have a 26,800 mAh Tecnipro P26 that is a brick. Anker itself has seemingly every different possible battery capacity option out there, so too many choices may seem overwhelming. But the more you go, the more weight you'll carry. I took this to Disney World in a backpack. On its own it is perfectly fine. But as you add everything up, you end up carrying around a lot of total weight. So shaving some ounces can be good if you are going to be on your feet all day carrying it in a bag or backpack. But this one is slim enough to fit in a pocket which doesn't hurt my back or shoulders. Personally, I'd go a bit smaller for being on your feet all day carrying it in a backpack. If you aren't on your feet all day at Disney, this is a great balance of capacity, form, and weight.
CAPACITY
This one hit the sweet spot for me, a lot more than my 1,000 mAh little lightweight battery stick, and fits & weighs a lot less than the 26,800 mAh Tecnicpro P26 brick that I own (good for when you want to go big or go home but not suitable for literally carrying a long time). With 10,000 mAh, it is more than you need to refuel your phone once or twice in a day. For comparison, here are the battery capacities of recent iPhones --
3,969 iPhone 11 Pro Max, 3,110 iPhone 11, 3,174 iPhone XS Max, 2,942 iPhone XR, 2,716 iPhone X, 2,658 iPhone XS, 2,675 iPhone 8 Plus, 1,821 iPhone 8. This is more than an emergency reserve, but full refueling for a few in your family.

TOP Batería Externa
Reviewed in Spain on December 31, 2018
NOS GUSTA 👍:
✅ Está construida en material plástico de alta calidad y tiene unas dimensiones reducidas, destacando su espesor mínimo
✅ Una de sus caras está hecha con material antideslizante para que no resbale en las superficies más lisas o cuando la utilizamos cargando junto al móvil. Además, se suministra con una funda de tela para protegerla.
✅ Incorpora carga rápida en ambos puertos, siendo de tecnología QC 2.0 en la entrada y QC3.0 en la salida.
✅ Para cargar dispositivos tiene un BUEN rendimiento, especialmente en el modo de carga estándar (5V), manteniendo en toda la descarga del power bank una potencia estable que puede llegar hasta 18W.
NO NOS GUSTA 👎:
❌ Tiene un único puerto de salida USB.
❌ La indicación por LEDs es algo imprecisa en su último tramo, permaneciendo mucho tiempo en la descarga con el último LED encendido.

ANÁLISIS ANKER POWERCORE SLIM 2 DE 10000 mAh
-------------------------------------------------------------------
RECARGA DEL POWER BANK 🔋
El power bank Anker se puede recargar a través del puerto micro USB en modo Recarga Estándar (5V/2A) o en carga rápida Quick Charge 2.0 (9V/2A).
Según el modo utilizado, el tiempo de recarga del power bank fue:
-Recarga estándar 5V: 5h
-Recarga rápida QC 2.0: 3h 30min
Recordamos que para el modo de Recarga Rápida es necesario utilizar un cargador compatible con QC 2.0 o 3.0.
CARGA DE DISPOSITIVOS 📱
Este modelo dispone de un único puerto de salida USB-A pudiendo cargar dispositivos en modo carga rápida QC 3.0 o en carga estándar (5V/2,4A) siendo 18W la potencia máxima capaz de suministrar.
Además, permite cargar dispositivos de baja potencia (superiores a 0,3W), por ejemplo: NO carga Mi Band 2 y SÍ carga unos auriculares bluetooth.
Sin embargo, no permite Pass Through Charging (carga de dispositivos mientras se recarga el propio power bank).
DESCARGA DEL POWER BANK ⚡
Para comprobar el rendimiento del power bank Anker y conocer la energía máxima que es capaz de suministrar a nuestros dispositivos, lo hemos descargado completamente en cada modo de carga disponible en sus puertos de salida.
Si el power bank Anker tiene una energía acumulada de 39Wh (10000mAh/3,85V), la energía obtenida a la salida es:
-Descarga estándar 5V: 31,91Wh (82,88%)
-Descarga rápida QC 3.0: 30,02Wh (77,97%)
