This slim 5000mAh battery is awesome

This is highly respectable as most decent battery only delivers 70% to 75% of it's rated capacity in real life

I used this charger about once a week for almost 2 years but, like other users have reported, the battery swelled up and the case split open

For now, this battery bank is the best option I've found for a slim, highly portable battery bank.

I've purchased 7 portable batteries of different sizes from different companies.

I've definitely buy this again when the batteries in mine are fully depleted.

This is a nice slim battery that will put my Iphone 7 back to 100% from 30-40% twice and more

Some external batteries are bulky, this one is nice and slim and just enough to get me through a night out

great small, light, and powerful battery pack.

The perfect battery for when you need to charge your phone but do not need the extra bulk of my batteries

My goal was to find a compact battery and some small USB adapters that would all fit inside the pouch on the solar panel.

Then when it's time to charge your phone, you have the option to connect the battery to your phone as appropriate.

It's also stylish, if batteries can even be 'stylish'

Nice looking battery.

After the battery on the Slim 5000 was fully drained, I charged it to 100% again

I think this is a EDC dream for portable batteries.

Charges it up and the next day she had to use it because her battery on her phone went dead.

Great little battery.

Too bad all of the other portable battery packs I am seeing on Amazon or no-name and presumably cheap Chinese

Great battery backup for Samsung S6 - my wife loves it

Great portable battery to carry with a phone

The battery inside was defective and bulged out making the plastic casing crack

so I purchased this portable battery.

This is a perfect compact battery for all day recharging of your phone.

We're awfully sorry to hear that you’re having problems with the PowerCore Slim 5000 battery and sorry for the inconvenience has caused

Well, the battery is expanded again

As is the case with every Anker product I have purchased, this battery works well and actually performs slightly better than advertised

If you are looking for a small, slim portable battery then look no further

For portable battery with 5000mah or less, the common form factor is the lipstick style cylindrical shape.

This is definitely the best sub 5000mah external battery to date.

life• I like the form factor way better than my Anker 2nd gen Astro E1• Nice little micro fiber pouch for storing the battery while it's not

so in my eye this battery is the best to have during your travels

Great battery, very slim for the capacity and charges rapidly

I find it can charge my 6S from a completely dead battery about 2-3 times which is great for how slim it is.

Yes, there are larger, bulkier cellphone batteries, and a few even thinner designs out there, but Anker balances both energy and comfortable dimensions

This battery is awesome

Great battery.

Conclusion: Great battery bank

Overall a great battery.

what a great battery

The new battery is working just as good as the last, and is making me as happy as the first

Great battery back up

good design and good battery life

Great battery - every bit as good as the Mophie but significantly less expensive.

Love this battery

Other than the price, it's a nice little battery but holding only 5,000 mAh, it's not worth the money they want for it anymore

This gives my Iphone 6 more than 3 complete charges, but my phone's battery is pretty deteriorated.

I really like this battery

I ran my battery down on my iphone 6s to 50% and I immediately started the chargering my phone with this portable battery

We both have iPhones and this battery was enough to give us each an additional charge ( phones were not completely drained).

Compact and good battery life

Great battery. can fully recharge my cell phone three times, or get hours and hours of video streaming

This is a great portable battery for your phone

The carrying bad is somewhat annoying, but the battery itself is very nice and is got a good grip too.

I purchased the PowerCore 26800 about a year and a half ago, and that can charge devices at up to 3.0 amps, so I was a bit surprised at how much slower this new battery is.

It's a useful pocket sized battery.

The battery has clean smooth edges, the USB cable fits snugly, and the LED lights are informative

Will recommend to friends (especially us who now play Pokémon GO that drains our battery so much!)

Anker has improved on their stellar battery reputation with this one.

This may be the perfect external battery for every day use

We both have iPhones and this battery was enough to give us each an additional charge ( phones were not completely drained).

The battery is very stylish, with one side having curved edges and the other side having a textured pattern to grip onto with your hand/phone

These batteries are great when I don't have access to an outlet

Other than the price, it's a nice little battery but holding only 5,000 mAh, it's not worth the money they want for it anymore

The solves the problem of bulky battery packs

I have had several ANKER portable chargers, purchased as gifts as well as for myself, but this one is easy to hold with the phone

Don’t think about it just buy it cause it is so good and charges your phone as fast as it can

Do wish it would charge my cell faster but nothing is perfect...then again this is as close to perfect as you can get.
