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)

Does NOT have Samsung "fast charge" or quick charge but will still charge my phone to 100% in a little over an hour (Samsung S7) which is on par with most standard wall chargers.

Battery Charger does not do a fast charge

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

The only reason this is a 4 star and not a 5-star review is due to the lack of USB-C fast charging on our Pixel phones

Like most of these it takes a while to charge up (expect an entire day to charge this bad boy), but once it's charged it will give any of your USB devices a quick efficient charge.

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

Works great, charges devices quickly, and lasts a long time.

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

Very good and fast charging

Pretty solid as a power bank in terms of steady charging.

Not the same as fast charging obviously, but it charged very fast even though I was using my phone while it was being charged

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

Holds a great charge

I got a full charge on my Samsung note 4 in record time and it barely dented the battery in the powerpack.

Fast charge

This is a life saver after it's charged.

Defective on arrival, the charge lasts a few hours then runs out even after leaving it charging overnight

Gives a fast charge like the 3 USB ports but a little heavy

doesn’t care, all they told me was “use the proper charging plug (which they don’t provide) will not buy their product again

Fast charges cell phone and tablet.

Great product, fast charge.

The problem goes away when the 3rd USB port is charging a phone

Great charging

It works well and charged pretty fast.

Charging is slow and takes hours to get fully charged but with high amp wall charger it can be charged faster.

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

The charging was great and lasted for days, but to recharge you have to store a cord and keep track of it.

powers 3 devices at one time never loses a charge

I absolutely love it!This one charged 4 times coming out the box

Held charge well and charged phones and fish finder quickly.

I can confirm that the power supply effectively charges three phones simultaneously without loss of speed or excessive heat, even when fast charging

Today, however, the charging port broke

My husband and I were able to charge both our phones during the day, and mine was fully charged (from 30%) within a half hour, using a fast charging cable.

Very durable and hold a great charge.

Finally a power charge I can trust.

Packs a punch and charges pretty fast

The charge this battery holds is amazing

With this battery is a slow charge at best

Now it won t charge

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

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

Works really well and charges fully overnight

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

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

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

I've gone through two recharge cycles with it at this point, and it's worked great to simultaneously charge my Samsung Note 8 and Tab S3, without barely even denting the charge

I purchased two of these, one for myself and some other one for my girlfriend, and they both work really good and charge fast.

Strong charge and long lasting battery

That's amazingly fast for a phone that doesn't have a fast charge mode

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

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

, then the battery crashed and it stopped charging.

Gives and takes a solid charge.

Holds good charge but kinda bulky and heavy

Super fast charging!

Best charge is regular charger and plug it in overnight.

Multiple charging capability!

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

The charging port dislodges and falls into the charger

Fast enough bank charge

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

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

Excellent product, the charge is great.

The charging is really fast, you can charge your phone like 4 times without re-charging the power bank again

Great charging bank if you wanna go camping or on a trip

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

The charger works very well better than the Anker charges in my opinion

It feels like this bank can holds its charge indefinitely

Love the charge 😍

Just an expensive normal charging battery

Also the charge plus inside the charger didn't work and broke the third time I attempted to re-charge the battery.

It seems to charge better even though the other power bank has a Quick Charge port for fast charging (that port does not work if charging other devices ether).I have tested it by charging my S7, a Kindle fire, and a camera battery at the same time and it performed perfect.

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" !

The safety is great so its not over charging my batteries and causing them to over heat

I was hopeful when I 1st charged

It tends to lose its charge

Held a great charge for my iPhone and iPad while I was traveling.

Takes awhile to charge the unit but was excellent at charging my phone and iPad several times while on a long trip and it never lost its charge!

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

it holds up really good charge for long time

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

Recommend the smart charge slot for the quicker charge rate

Good solid, holds the charge long time, but doesn't charge my iPhone fast.

It fluctuates from regular charging to slow charging, but I have yet to see it actually Fast Charge

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

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

The even more annoying thing is that it is not fast-charging

Heavier and bigger than I expected, but wow, you can get many, many charges from

When it gets really low, you might as well plan on leaving it charging for the night

This power bank's weight is similar to a brick, but I don't mind, because what it lacks in weight, it surely does compensate with fast charging abilities

So i bought another one specifically for fast charging capability.

This thing is heavy, BUT its charge is amazing

and it would not gain any charge.

i have seriuos problem with Portable Charge RAVPower, the battery doesnt work correctly, because dont charge full, charge just one light

This portable last me days when its fully charged

Hands down the best charge I've ever had.

It gives a fast charge and the battery pack lasts a long long time

Works really well and charges fast.

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

This bank kept its initial charge (and my iPhone X topped up) after 5 days in the parks, I only had to charge it once I returned home.

You must charge the battery via a USB charger that you already have - in my opinion eliminating much of the "fast charging" claims from RAVPower.

Great capacity and fast charging, so far very reliable

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

The smart charge port charges my iPhone X (formerly worked well with my iPhone 7) very quickly

Great battery life and charges really well!

Holds a charge well, I ran items overnight and it still had plenty of power.

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

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

Although it has 3 outputs, I would try to stick to 2 devices at a time for optimal charging

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

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

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

My iPhone 8+ gets about 2 full charges before the battery dies

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

Fast charging and enough charge for multiple devices.

It has a very very slow charge for a

Worked great at first but after a few months it will no longer charge

The charge was good, but I have to replace the product after a month.

I keep one at home for fast charges away from sockets, and another one in my car in case my phone is dying or whatnot

Great fot charging tablets.

This thing is great, charged my iPhone X with the smart charge and my galaxy note 5 at the same time

The fact that the 22000 is smart enough to know the best charging power for each device for fastest charging is an added bonus

Perfect to keep everything charged and the family happy.

I bought this because the title says it is a fast charge technology, but unfortunately not QC 3.0

Unit charges from zero in about 5 hours using fast charge

Not as fast as i would like it to be, but it gets the job done
