Like all Anker products, this uber compact external battery is awesome!Size of a lipstick tube fits into any type of pocket, purse, small carrier

I also use a larger anker portable battery for camping and don’t leave home without one

Great tool...have kids who like to play on my phone when we r out , now i dont have to worry about them draining my battery...

I was looking for a charger that would provide me with one full charge after my handset’s battery was almost depleted.

I like my new portable battery.

All of my portable batteries are anker batteries because they never fail

Also can’t help but think it drains the battery unnecessarily.

I purchased it to be sure I would have enough battery power for my daughters wedding and after charging the device to be ready, the evening I needed it, it failed to work

Great little battery charger for a quick partial charge (depending on your phone).

This is a good, tiny battery pack

I appreciate that the battery is compact and easy to use

I got some really good external batteries from Anker before, but I'm one of the odd men out with this Anker Powercore+ mini 3350 mAh external battery.

** Anker makes a bigger external battery that is perfect for camping -- this smaller battery has been very useful on day trips and sightseeing where I am taking a lot of pictures and not near a power source to recharge my phone - it fits perfectly into a small purse and it recharges my phone pretty quickly

I own many portable battery backs of different capacities

Anker PowerCore 5000, Ultra-Compact 5000mAh External Battery with High-Speed Charging Technology, Power Bank for iPhone, iPad, Samsung Galaxy and more <

the problem, at least for the moment, went away - it happened to be after I had fully depleted the battery from use that the next recharge was correct (as well as the next one after that), but that may or may not be a coincidence

Great little portable battery pack that isn't super heavy

Slightly bigger than most lipstick and holds enough battery to give me almost a full battery!

AMAZING battery life.

Will charge battery over night and will die the next day even before use

So much better than my other portable which lost battery after 1 use on my phone.

I left the charging cable at home by mistake and wasn't able to recharge the portable battery

Their other batteries have the same quality issues.

my battery dies and I need to call Uber.

Nice and small, but a larger battery would be more useful in almost all cases.

If that's the case, I sure won't be buying these again, especially as other backup batteries I own have worked well for years

Great little anker battery, seems to work well enough!Read more

Great back up battery in a small footprint

About the same time, the PowerCore+ red light turned off, indicating its internal battery was depleted

This is the best backup battery I've found -- holds a ton of power and tells you how full it is

Great compact and portable battery charger

It is really a good battery, good design, good product, and great value

I recommend this to anyone that needs a portable battery with a small size and weight.

Really good battery pack

awesome portable battery

This is the worst battery I have ever purchased

Doing so requires using a map app, which drains my battery

The battery is sleek and small

Battery dies pretty fast even after a full charge.

This battery worked well for about a week

This battery is some compact that I can easily take it with me in my pocket with my phone

I actually boosted the battery on my iPhone 6s twice on lunch breaks in the back of beyond

the problem, at least for the moment, went away - it happened to be after I had fully depleted the battery from use that the next recharge was correct (as well as the next one after that), but that may or may not be a coincidence

That is a reasonable price for the guarantee that I'll never be stuck with a dead phone battery.

Battery works for about 5mins.

I LOVED this portable battery charger

It's a shame because my other PowerCore 5000 works great and can recharge a near-depleted battery on an iPhone 7 Plus and a near-depleted battery on an iPhone 8.Updated August 2, 2018:

But this Anker battery stopped working after less than 6 months, and that is with VERY light use (maybe once a week at most)

** Anker sent me a brand new battery- great customer service

Has about enough battery life to charge my phone once before needing to be charged again.

I would absolutely recommend the next battery up.

I had a cheap battery from another site work perfectly for years until after so much use it would not hold a charge

Nice little battery charger.

Perfect size for international travel, carry this with you after you deplete your battery from Google Maps exploring a new city.

Also good battery life.

Everything works well, it has enough battery for my iphone 6s+ to charge more than once

Everything works well, it has enough battery for my iphone 6s+ to charge more than once

I bought this as a smaller portable battery to keep in my bag

The battery drains while the device is not in use and the charge does not last long enough to charge a phone below 25% battery life.

They did not want to trouble me with sending back the defective battery

IOS 11 is draining my battery like an energy vampire, so I used the charger again this morning

Great small portable battery.

Once this portable battery is fully charged it stays that way for quite awhile, and I can charge my iPhone almost 2 full times

This is a great battery to keep in your pocket

After 3 years, battery is totally dead

so I wouldn't constantly worry about not having enough battery life on my phone.

My Panasonic eneloop rechargeable batteries that are made in Japan definitely don't work that way.

Great battery and very portable

Good battery life

I dislike that I have to go to youtube video to find out that the power lighting (indicator light) is also the button you have to press to turn it on or else you would think the battery is defective.

This battery dies quickly.

I use this product multiple times a day with my unreliable phone battery

It holds one full charge on an iPhone 6S, and gains battery back fairly quickly with an iPhone charger

The one they supply only connects the portable battery to the outlet (but you still need the base with prongs).

Great material, good battery life

Great battery pack and easy to charge!

doesn't quick charge, but seriously smallest reliable little battery you can find!

Powerful battery pack.

pretty good nice size as a back up battery for a vibrator

pretty good nice size as a back up battery for a vibrator

Works well, great battery, but if you have an iphone you will have to use your iphone cable

I love this mini rechargeable battery -which is what I use it for

It is very important while traveling, specially if you are roaming at places that the phone would be constantly searching for signal and drain the battery

, I keep it in my purse and I've never found myself in a situation where I didn't have enough battery power available since.

IOS 11 is draining my battery like an energy vampire, so I used the charger again this morning

Great little external battery.

Either way, it does the job after this terrible new iPhone update that drains the battery.

So disappointing as I was planning on using for upcoming trip

I’ve had it for over a year now and it still works as it were new

and it still works as good as on day one.

It doesn't charge my phones as fast as I would prefer so I have to deduct a star

Its not as strong as when i first got it, but i still get a good charge.

I bought one for my mom as well as
