This charger carries enough power to charge my phone fully at least 3 times (from about 10% to 100%).

Great power bank and great build quality

We haven't needed a portable power source

Any decent USB cord with a good USB power supply behind it will charge the PowerCore at a solid 2 amps.

I like the fact that it is a super fast charge however I’ve only used this product on 2 trips and now the battery pack loses power with one device charge

One charge to my iPad and lost 1/3 power on charger

Excellent Power Bank

very good power bank

Obviously it's not going to lose power if I don't use it, but batteries will leak slowly over time

Great power and slim and small

Very solid power output under load.

After doing that they took my address and sent me another power bank which worked great

but i guess that is to be expected for such a robust power source.

Unfortunately, it stopped recharging fully after a dozen times use, and now it barely has enough power to recharge a phone before it

All power was drained and I ended up with no way to charge my tracking device except a dollar isle charging block

Excellent power storage and very fast charging time

It's a great power bank when you need something to charge multiple devices at the same time

One even bought a way more expensive power bank than this

Enough power to use ALL day long charging phones

A great power pack

Once fully charged, it had enough power to charge my Android device at least 2 or more time when power level was around 10-20% as well as a second phone or tablet.

I personally would or get a stronger power

It has enough power to charge my phone up 6 times

but it takes forever to recharge once it loses all power.

I had been shipped a defective power bank and I decided to contact customer support

This is the best power pack I ever owned, and the price was great

I could not find UL Certified Safe power banks but Anker's power banks have the best safety record of any brand that I could

Best power bank I have owned.

One of the best power banks I've ever invested in.

and it’s the best portable power

I thought I finally found a power bank worth the

Solid power supply.

Great power block

Best power bank till date!!

This is a great power bank.

, I bought this when I went camping and my phone died and the two power banks I brought with me only charged my phone 25% all tegother, Pissed off with garbage quality power banks, I bought

More than enough power for what I use it for

We lost power during the Nor’easter and this was able to keep all our phones sufficiently charged!!

We still haven't completely depleted the power from this

The charger's compact size means it's just about ~1.5x the size of a smartphone, but packs enough power to charge a phone to 100% and keep it doing busywork all day long

Also great when you lose power at home.

I got this power back back on July 2017 and it worked wonderfully for me until lije2 weeks aho that it started to act a little bit crazy sometimes it worked and sometimes not so I contacted anker support service and the respond super

The good - this power bank has a huge capacity, and the ports charge at the advertised rates

Really nice power bank

It's great for a weekend camping trip where you won't have any AC power available; you can get all the charges you will need.

Great power bank, super high capacity and provides multiple charges for two devices at once!My one complaint is the indicator light is often off from the real current charge, I understand there are only 4 lights

He would be 1700 miles away from home and needed a good power source.

This is a BEAST and definitely the best power bank I have purchased

Thankfully, that one held its charge so I could get enough battery power in my tracker in case of emergency, but not enough to let family

Fantastic power bank

Love that I get multi charges and friends always borrow my power when we are out

So far it's a decent power core

Great power bank, love it

It's a great power bank!

Nice long sustained power

Use it when I go on trips, out to the park, camping, doing anything where there is no power and it works good

However, there is sufficient power to charge several items in a short amount of time.

Also great to power speakers/pandora/iheart radio, when you're sitting pool side, on a golf cart or in a hotel room.

Amazing power bank, I got it for my kids overseas trip and they were able to charge their iPhones and iPads during the vacation trip, I use it at work for my phone and charge faster than a computer

This thing saved us during the hurricane season when we lost power for several days

Spent a whole week travelling and walking over 8 hours a day and not once did I loose power on my phone or action cam... would purchase it again without a doubt.

There’s not even enough power to begin to charge my iPhone 8

Sure I've been doing research for almost a month trying to find the best power bank for my off label use

If you don't want anything fancy and are looking for a quality, solid, reliable, powerful power bank, this is likely where you'll want to look

it holds power really well.

Had great charging power but wouldn’t last long, and now it doesn’t work at all

Never had to worry about my phone not having enough battery power (have a Blackberry Keyone)

Great portable power bank

There were only short unexpected power failures, but nothing protracted.

The power saved in the powerbank did not deplete even when it was not being used for a week

A little heavy but a good power course for several items at the san e time

Great power capacity

I just got a faulty power bank

This is a decent power hold

It gave us great peace of mind to know that we had enough charging power for several days with this device.

Great power get for daily

Lights up like it has power, but doesn’t power anything6/22/2018 update:After giving this item one star, I was contacted by the Anker company who informed me there is an 18 month warranty , and immediately shipped me a new one!I used

This is the best power bank I have had

Anker makes some of the best power banks available, and this one here is no exception

It is every bit as good as my old power bank

Stores enough power to charge my iPhone 8 Plus multiple times without having to recharge.

I travel for work so a high performing portable power supply is a crucial tool for me

Have had it for a while and trust me when I say it's enough power to last several days.

Excelent power bank works pretty good

I use it when I'm not near a handy outlet (my side of the bed, for example or when watching TV and my family is hogging the available power sources)

the best power bank I ever

This has a lot of charge in it and works perfect for weekend trips away from reliable power outlets

I feel more secure when it is hurricane season and we lose our power

We would carry in our backpack and it had enough power to charge 2 iPhone 7’s

I've been steadily using this product now for week and a half this is by far the best power bank I have ever used at a great price this can easily give my Samsung Galaxy S8 two full

AWESOME POWER BANK

This is by far the best power bank I have found.

Enough power to keep 2 phones and 2 fans charged for days

I would highly recommend not only to hikers but also as an emergency backup for those times you might lose power.

The smaller PowerCore of course weighed less but still has more than enough power for 2 or mor e recharges of my devices.

This is a nice power charger, I use this everyday for my phone !!

best power pack in the market

I've bought some power banks, but they don't necessarily provide enough power if you wait until your phone is about to die.

Fast power and convenient

Came in handy when we lost power too

It’s a great power bank but if it runs out of juice one day you won’t be able to use it at it’s full capacity the next day.

Great power bank i ever had.

This is a good power bank

I've had this for a year now and have used it for weekend camping in US national parks, trekking in Nepal (with very sketchy power), touring Europe, and just generally flapping in the wind.

This was not convenient as I could not stay that long just for my power bank to have enough power

With the Portable Charger powering off, it fails to charge my devices.

Anker has definitely got an edge over all other power banks available in the market, Using for a year now, charges up iphone super fast and has an awesome after sales support and customer support team I have seen far

Not to mention, I didn't use it for like 3 weeks because I wasn't leaving the house very often, and it didn't even lose any power

Charged it fully, in case of power outages or lack of power source over a three-week trip.

I contacted customer support with my problemA few days later the defective power bank was replaced by a new one

I tried to fully charge it before I use but it seems like it stuck at level 2 power for forever

The best combination of portability and good power

Best power bank!!

It began to lose power quickly

Perfect portable power source for traveling.

It holds enough power to charge my iPhone 7+ several times, or multiple devices at once a few times as well depending on how big their battery capacities are

and it sucks all the power that i have left out its like it counts down

, I charged 3 phones and there is still power available

Provides excellent reserve power for my electronic needs.

Awesome power!

Do yourself a favor and skip the cheap power banks and get yourself one of these

Awesome, great power core

It has been a fantastic power bank but unfortunately, it stopped working completely

Best power bank I ever have!!

Enough power to do iPad and iPhone

so I wouldn't recommend it to someone looking for a reliable power bank

True quality and technology coming together to produce a strong, reliable, and real power bank

Great power pack.

This is one of the best Power bank I owed

Amazing power supply in compact design and for a great price.
