Works really well and charges fully overnight

Fast charge for devices and the power bank itself holds a long-lasting charge as well.

I’ve tried left on it die completely as well as charging it all day.

The battery works very well, and actually fast charges my Galaxy

I thought it was charging slower than usual but that’s not the case, I’ve changed outlets 2 times & changed the charger cord 3 times.

Super fast charging with long lasting battery

It worked great for a year, then it stopped charging any devices

Awesome portable charge for phone or tablet when you don't have access to a usb charging port

Held charge well and charged phones and fish finder quickly.

worked well for a couple months, then it stopped charging, i have an asurion

Just under 1 pound and delivers a ton of power with Smart charging

So i bought another one specifically for fast charging capability.

This charging back is amazing in the least it gets you a full charge very quick and you can use it time and time again before you have to charge the pack plus the use of simultaneous

I was hopeful when I 1st charged

This thing is heavy, BUT its charge is amazing

Great battery life and charges really well!

Hands down the best charge I've ever had.

The charge this battery holds is amazing

Although I don’t recall a fast charge feature advertised, this bank charges our devices rapidly.

But every time I find there is no charge even not a single point remains charged i.e. completely dead though I stored it fully charged by "48 hours" !

Compared to the smaller battery cells I own that only charge an iPhone 8+ two or three times max, this has a solid 10+ charges and offers three USB ports to charge multiple phones at the same time

They sent me a new one, no hassle, no extra charge.

It charges our devices, one android and one iPhone, multiple times before it loses its charge which is ideal for traveling.

Takes a while to charge up but gives a good, fast charge!

Fast charges cell phone and tablet.

It feels like this bank can holds its charge indefinitely

The iSmart system works well and charge phones in about 2hrs (if not less) which is pretty nice for the target costumer of this product (regular people who don't demand quick charges and don't deal with USB-C)

I’ve tried left on it die completely as well as charging it all day.

Sturdy hardware, packs a lot of juice however it's does not register as fast charging for my USB C devices, this isn't good for me since I use pixel devices

Great capacity and fast charging, so far very reliable

Very good and fast charging

, then the battery crashed and it stopped charging.

It held a great charge, able to charge my iPhone 3

At FULL charge, it looses more than half of its charge after charging only 1 (

Very happy customer!Loved this at first but after 5 months the charge is depleting very quickly.

Charge time takes between 10 to 12 for a good full charge.

Best charge is regular charger and plug it in overnight.

Perfect to keep everything charged and the family happy.

Very durable and hold a great charge.

With this battery is a slow charge at best

Holds good charge but kinda bulky and heavy

The smart charge punches my phone from 20% to 100% in an hour.

I get several charges on my phone, excellent for emergencies.

and it would not gain any charge.

My "actual" Samsung fast charger works perfect and the phone says "fast charging"

so I probably only got about a dozen charges out of it before it died

The smart charge punches my phone from 20% to 100% in an hour.

Great fot charging tablets.

Gives and takes a solid charge.

This product sucks.the charge goes down to fast without using it after fully charged

We had three people using it and it kept its charge great.
