Xiaomi20000mAh Redmi Power Bank 74Wh 18W 3.6A Rapid Charging Dual USB Outputs for Two Devices at Once, microUSB & USB-C Input, Portable Travel Charger iPhone iPad Samsung Smartphone & Gaming Devices

The power bank is great. It lasts a long time and can charge the cell phone several times. Super fast and great quality.

Charges well, quickly charger for phone and ather device , little bet heavy but works good

Este cargador super rápido y le dura la carga lo mejor es que lo mande para cuba es lo mejor que le mande a mi mama

I got the 20k version a few months back but it's too heavy to carry in my purse and only let's you charge one thing at a time. Bought this for on the go for a trip.Pros: can charge 2 things at once, cell and headphones which I love. Passthrough charging - can have it plugged in to charge while charging 2 thingsCons: no fast charge. Need to leave it charging several hours for full charge, but lasts all day.

Xiaomi generally makes great electronics so I chose this particular portable phone charger and so far it’s working quite well! I like how it has rapid charge and I was able to charge my iPhone fully in less than an hour. The unit was barely warm to the touch while charging two phones at once which means the internals are high quality.The power bank is quite slim so it fits easily in my briefcase and also my gym bag when I need to top off my phone while on the go. I was able to charge my switch when I forgot to charge it the night before and was super happy about that.It comes with a micro-USB cable which is nice. At this price point, the power bank does not come with a USB to USB-C cable but I had a spare one and was able to fully charge the power bank fully in roughly 3 hours. Overall I’m happy with the purchase and I plan to get these as inexpensive tech gifts for friends.

Pros: Able to give a full charge to an ipad air 4th generation and still power remaining in the power bank. Can charge a mobile phone about 4 times. Charge transfer rate is vey fast. It can also transfer charge to a laptop, but i have not checked how much can it raise battery level in my lenovo prestige laptop.Cons: heavy and bulky.

Llego con ralladura en unas de sus esquinas apenas a el abrirla, no sé si aya sido por mal manejo de el paquete o a el mal acomodo

I have no complaints so far. Fast charging works like a charm I use it daily and charge it completely twice a week.Some important is that it takes about 8 hours to fully charge using the c type charging port. Takes longer with the other port.
