When I first purchased this portable battery, I thought that there's no way it could be that great and durable, considering it was under $40

This battery works phenomenally, much like my larger 26800 model

Great battery and even better price

And my iPhone 5s has HORRIBLE battery life, it will jump from 70% to 30% to being completely dead with the opening of a simple app

I believe I had a faulty battery the first time

This is a killer battery

Love this battery

Great battery pack

Great portable battery

Amazing battery

its a battery.. if it works then its good.

the search for a good connection drains a phone battery or two (or three).There are slightly cheaper Anker chargers with similar form factors but only one USB port, as well as giant ones that have the same number of ports but much larger capacities; I’d recommend skipping all those in favor of this one

I totally understand there's always a slim chance for a battery to just be a lemon, and they handled it great

suck drain my cell battery like crazy

Love this battery

Actually 13,000mAh, unlike most portable battery claims... also it's really smart

I'm honestly never buying another cheap battery pack

Love it includes a mesh pouch to keep all included parts (external battery and its charging cable) together

Love this battery

I have had this PowerCore since May 2017, and I must say it is the best external battery I had ever had

The battery for the most part is exceptional, the capacity compared to its size is unmatched

This is a nice battery and I can charge a number of devices as I’m on a day trip

This battery is amazing, Charges my phone in about 30 min and doesn't event make a dent in the battery's capacity

Very good battery.. super like 👍🏻

Great battery charger

This extended battery is awesome

Excellent battery pack at reasonable price

COMPLETE RUN-AROUND, no replacement of defective battery and

I fully drained the battery to see how long it would take to fully charge.

They're by far the best battery pack I've used.

This is a great external battery...it lasts for hours

Great battery pack

I bought this to have with me on a long business trip to avoid the dreaded battery drainage

Awesome battery.

Perfect for long days at Disney World that drain a phone battery quickly

This portable battery is amazing !

Even works great to top off my camera batteries that let you charge the camera via USB, like the Panasonic TZ100 and G9.

Great battery life

Its awesome battery pack for travel and better because it doesnt bulk your phone.

It's not too bulky and the it has a great battery life.

Anker makes THE BEST backup battery chargers in the business.

For the first week, the battery was slow to charge

In particular, I purchased the "Portable Chargers RAVPower Luster Mini 3350mAh External Battery Pack Battery Bank External

GREAT BATTERY

I had to replace a lost Jackery external battery that I had for about 4 years

Mine is always dead battery even if it is fully charged I think it's defective 😢 bought just last September 2017

Maybe I got a faulty battery

I own 3 portable batteries and i've used many others, this one really stands out

I love this battery.....it delivers as promised

great additional battery

Great back up battery bank

The battery charges the phone at an abysmal pace, slower than the phone runs out of battery

No more Battery problem

This battery back up stopped working after some time

Poor grade battery cell is used for this power bank.

This little battery packs a punch and can charge my two phones no problem before I have to charge it.

I was able to charge my s7 edge 3 times with one charge on this portable charger (my s7 had horrible battery life)

If the batter life for it is only a year then I guess it's a good portable battery because it made it for 11 months.

If you need a small portable battery bank, that will actually fully charge your phone a few times over

Great portable battery that has never let me down.

Now I stopped the discharge when the pack's LED started blinking to indicate a low battery and I realize that there is some headroom to keep the batteries from fully discharging and damaging the cells, but 3 Amps seems a little excessive.

Says the battery could charge a Samsung Galaxy and I got warning message that said my battery was damaged due to a third party charging device

If your reading this you have found the best battery out there

However, if the battery is in my backpack and the charging cables are hanging out, attaching a device does not start charging

Great battery pack.

Really useful little backup battery

Super fast charging and the battery lasts for a long price

(it takes several hours even new) and she's using it as a portable battery

Very inconvenient when battery is not easily accessible like when in backpack.

My favorite battery pack EVER

Great for trips too so your phones don't die on you as they always do.

Works as it should if not better!

All in all, a good purchase with a product that works as it should.

You’ll want to charge this overnight if drained as it takes a while to do so
