I can't tell if fast charge works on my Galaxy S7 because it doesn't say fast charging on my phone but it is possible the phone doesn't recognize it as fast charging but it does appear to charge pretty quickly.

how much charge life it has and it has wireless charging that's easy to use as well

The battery did not even work for more than 2 times of charge, contemplating that although it has a good duration, it is very slow charging, I was disappointed

It charged quickly and held a charge for a long time, but in the last couple of days stopped taking a charge and drains really quickly (I'm talking one charge fast)

It works great and charges just like

Doesn't show as "fast charging", but the speed has been comparable

and then I bought a new phone the Galaxy note 20 ultra 5G which I discovered has a new charging cable a type C to type C super fast charging

Excellent charge life even after charging a couple of phones100%.

The charge on this item is enough to recharge my phone in emergencies

It does not say fast charging but i went from 9 percent left to 100 as if i was plugged in

Works great for fast charging phones

This portable charger is pretty slim and light weight, but allows for fast charging of all devices

This portable charge is small and light, I can put in my small purse during the travel

This charged my phone the first time decently but was drained charging only my phone one time

Superior charging power over those other portable chargers

Only con is that it doesn't do modern quick charging speeds, but that's honestly fine

Keeps the charge well

Great for travel, but charges slower than I would expect on USB C, especially off a MacBook charger

I suck at plugging in my phone at night, but I'm good at keeping my portables charged

It holds a nice charge and is great to keep with you as an emergency charge center (as in the nearest outlet is next to the middle of nowhere)

It works as intended but charges slow

Very slow charging phone and slow charging the battery itself as well

However, once it's charged up, the self-discharge rate is slow, so you don't have to constantly keep it plugged into a wall wart, etc.

It works as intended but charges slow

Hoping for a fast charge and it does

Very slow charging phone and slow charging the battery itself as well

Fast charging and fast recharging

it does what it’s ment to do and has fast charging

Not fast charging at all…

This is a fast charging battery pack, only good for 2 charges on a Samsung S20 ultra at 1 hour each, at 5%

Great life and charging speed!

That being said it does charge my LG Wing which only accepts fast charging

I went to use this battery with fast charging cable for my Samsung

Kept a charge for a long time.. but 2 months later it wont work correctly

It charged quickly and held a charge for a long time, but in the last couple of days stopped taking a charge and drains really quickly (I'm talking one charge fast)

Holds a great charge

I’ve had several different kinds of portable charges and this is far and away the best one

This portable charger gets me 21/2 charges on my iPhone 11I use 2 different Anker chargers and my old one has lasted 2 years and still gives me 2 full charges on my phoneAnker is the best portable charging devices on the market in my opinion

The battery takes forever to charge (and I’ve tried different outlets) and gets extremely hot when charging

Slow charging

Rapid charge time and long life!

works amazing keeps me charged on the go

Love that it charges quickly - not a full speed fast charge, but something like 90% of the speed

Small, light, fast charging for my Android.

Slim size, holds a great charge, and super convenient.

Does the job well and quick charge

Sure they're are more powerful charging power banks but this one is sleek and gets the job done and lasts plenty long

Power bank has enough charges to power my phone for almost 2 days.

The lights indicating that the charger is charged are illuminated

The battery life feels like it could be a bit larger, but it had enough charging power to fully charge my Samsung a20e once and my bluetooth earbuds case 3 times on a single charge over the course of two

Yay, right!Fast forward 4 months after replacement, another dead charged.

Very portable, only 2 charges on a samsung a10e

I have a 45watt brick for my laptop from them that has fast charging function with the the smart iq technology and they both fly when it comes to charging

One of the slimest batteries I've seen and amazing fast charging.

Fast charging, and long lasting

Works great, 5 full charges on my Samsung Galaxy phone and still has battery power left.

At 10,000 mAh, I figured I should get enough charge to get me through a jam

It retains its charge very well and it’s sleek enough to carry on in my bag

I get one good charge from it before it runs out of battery.

We travel alot & it has a good charge, that lasts & keeps our phones going.

Also holds nice long charges on my iPhone

Heretofore I was tethered to a cord in the nearest outlet or waiting for enough charge to continue

It retains its charge very well and it’s sleek enough to carry on in my bag

I like the charging

Fast charging power, good battery life and light weight for traveling.

when that didn’t work I though it only worked with the charger it came with which is hard to believe and when it didn’t work with a usb c

Priced low enough to let the kids use them for their school tablets (& not worry about them dropping my other more expensive portable chargers) as well as to buy more for backup use

I've purchased several for myself as well as for gifts.
