Good battery life

Battery dies pretty fast even after a full charge.

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

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

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

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

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

I appreciate that the battery is compact and easy to use

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)

I would absolutely recommend the next battery up.

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

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.

Their other batteries have the same quality issues.

Great material, good battery life

I LOVED this portable battery charger

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

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

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.

After 3 years, battery is totally dead

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

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