if using fast charge cable).My only petty complaint is that it's a bit bigger than what I was previously used to, but it's really not a problem at all: just don't stick it in your pocket expecting it to fit comfortably

Initial charge wasn't lengthy either

I shows the top completely then used it to charge my iPhone 7 got me about eight charges did have an issue later on but Customer Service resolved fast.

If IPod, IPad or phone dies on me @ a bad time, I connect my Quick Charge and I am good to go in a couple of seconds instead of waiting hours for electronic device to recharge.

The fast charge port charged in about an hour, the other port charged a little slower but got the job done

It has charged both pretty fast, and it gives me more than enough charge to have no worries on a longer trip

The only "negatives" I'd mention with this device are that, while it supports "quick charge" and will charge larger devices, it does not support "dash charge" of OnePlus devices.

They support up to 18W but with this your iPhone can only charge up to 12W!Apple calls 18W charging “Fast Charge” and it makes use of new USB Power Delivery chargers.

I love it that i gave one to my family member and got me another one and love the fast charge feature

It has a decent charge and is able to charge my iPhone 6 times over

Fast charging, lasts many charges on my iPhone 7, great construction

I knew I wanted about 20Ah, Samsung rapid charge technology and light weight

It took me 3 or 4 recharges to drain the partial charge the device had when I received it

Was happy to see the "fast charging" pop up

Although this is a fast and powerful charger as it charges my phone using fast charge port in 2 hours but it seems that it loses its charges faster than old Anker

Great charge!!

I bought an Anker powerbank years ago, back when it used a proprietary charging input cable and charged my phone at a snail's pace (I lost that proprietary cable within the first year, but that powerbank charged so slowly that stopped using it anyway)

Wish is had dual inputs for faster charging

(Not used on this product) while it doesn't say it supports fast charging, the higher output side DOES fast charge my S8 even while charging another device.

Very good charging speed, too

It went through airport security in St. Louis and Las Vegas with no problems and the included cable allowed for fast charging my Samsung Galaxy S7.

given its size, it does a solid job at fast charging.

Fast charging and that extra USB port is convenient.

This can charge 2 devices at once, and it has a generous charge capacity, even when it's on the last bar of energy.

Great product, fast charging and capable of charging multiple phones, loved it!

Had some issues with led lights flickering on and off while charging

Has great charging capacity

holds a charge great and charges my phone as fast as Qualcomm quick charge.

I never forget to take this item on any of my trips, charging is also surprisingly fast

Granted there may be a compatibility issue in trying to use the anker portable charging bank with a laptop but it should at least charge a phone

My phone loses charge quickly so this battery bank has been tagging along with me.

Regarding the charging capability issue, though this model is already one of our comparatively high capacity model with heavier weight, usually an external battery could supply 60%-70% power to other devices

The unit does not show all lights indicating a full charge and the USB connector as well as my two month old A1265 charging adapter are toast

This device charges my phone as fast or faster than the standard Samsung Fast Charger and holds enough charge to recharge my phone at least 5 times

Granted there may be a compatibility issue in trying to use the anker portable charging bank with a laptop but it should at least charge a phone

It does not have fast charging capability for galaxy s8 as advertised, otherwise good product

My samsung galaxy S6 reports "fast charging" though I don't know if it's as fast as with the samsung wall charger.

Great portable charging bank, very durable feeling, takes a while to charge but charges my devices very quickly and lasts for days.

Holds a charge, easy to transport (a little heavier than I expected) and will work great for an upcoming trip.

Durable, capable of charging multiple devices at once, and, a whole lotta charge at that....

This unit will fit in a pocket and has no problem keeping you charged from the US to Asia and beyond.

Fast charge works great on the S7.

Fast charge works great on the S7.

There are other models that explicitly support the "Quick charge 2.0" or "quick charge 3.0" capabilities but that is irrelevant if your handset does not support those -- do a little searching on your handset to figure that out to make sure you find the right one for you

Although this is a fast and powerful charger as it charges my phone using fast charge port in 2 hours but it seems that it loses its charges faster than old Anker

However, to get the most of Anker's fast charging ports a higher quality fast charging cable is required.

I was deceived by Anker marketing that says "Fast Charge of iPhone, ..." into thinking this would provide the same sort of charge, it does not.

The only "negatives" I'd mention with this device are that, while it supports "quick charge" and will charge larger devices, it does not support "dash charge" of OnePlus devices.

Reliable , fast charging 18v , great capacityWorth every penny

It is small, fairly light weight, and seems to hold a good charge.

This charges my Samsung S7 Edge with the fast charging feature in less than an hour

The fast charge port charged in about an hour, the other port charged a little slower but got the job done

It appears that using the rapid charge port (it has one rapid charge, one regular), while it does charge faster, is not as

This item holds a nice charge and allows you to press the button to see small LED's light up in circle pattern to tell you percentage of battery power

It also charges quickly enough with a fast charging adapter

and it shows fast charging when hooked up

It seems that if number of charges is your most important spec you should not use the rapid charge point.

Fast charges too

The device itself charges relatively quickly and starting from a full charge, it was able to charge my Samsung GS7 4 times with some charge left over ... so far pretty good.

and it still has enough charge left to provide power for another week or two.

I have found both quick charging and 'regular' charging (18W and 12W port, respectively) works as expected

Lately the phone battery will actually go down because of the slow charging.

Device is phenomenal, very smart power features and very efficient charging

It holds a charge for weeks as well

Charge last a very long time as well

Fast charging input and output

I also tried using a wireless charger connected to it however the fast charge won't enable

Pros: - Carries a big charge at full capacity (capable of charging iPad tablets, phones, etc.

, I'm confident that it can charge to 100 in less time if I enabled fast charge

I get about 2x the charges as my older 10.4AH unit that does not have rapid charge

Anker might use the term “Fast Charge” but they mean something different than what Apple means

I also should mention it's doing this with samsung fast charging

Great charge, i was able to charge my Droid Turbo

This seemed to be one of the lightest units Anker had in this power range that said it supported Samsung charge

Also supports fast charging for my Galaxy S7, which is great.

I needed a portable charger that won't last long because I have multiple devices that are charged on the goal whether it be my iPhone or iPad, I also like how there is a fast charge port where it can charge your phone or any other device twice as fast as any other charger , I recommend you charging the device when it's fully dead and not in between to make sure the battery last longer than expected which is recommended by the manufacturer

It took a couple hours to charge (we used our own fast charged that we have) and held the charge for a couple weeks

This charger charges must fast than previous version and holds a charges longer as well

Has Power IQ 2.0 technology to recognize fastest charging speed by device

The reason I bought this was because of the 18 watt charging... faster charging means I can refill the battery easily

Fast self-charging "using an Anker fast charger "

My samsung galaxy S6 reports "fast charging" though I don't know if it's as fast as with the samsung wall charger.
