It always drained this battery down to 1 led left after one charge of my phone.

Favorite battery pack yet

Although this works VERY well and charges your phone quickly for hours, it completely KILLED my actual battery in the phone and i had to go buy a new one.

I keep it in my backpack & use it pretty frequently thanks to my phone's terrible battery lifespan

Overall great, affordable battery that lasts really long

The conversion in both directions is imperfect, batteries have some resistance, etc

Good battery. gives me about 3 full phone charges.

then the battery drains very quickly (like when charging two devices at the same time or in rapid succession)

My battery on my phone now drains faster that it will charge

Its a little bulky but its the best portable battery I've ever owned

Amazing battery

Good size battery, but why would you build a unit that turns itself off

After a couple months of buying the first product I got, the battery died extremely quickly

it works especially my son would be watching, it helps for extra charge when battery is dead and no outlet available.

The new battery is powerful and charges my

It's a shame because I LOVED this battery but only lasting as year and a half merits a one star reduction.

All 3 phones would end up gaining a minimum of 20% each and the battery in the power bank kept it's charge over 75%

This battery is weirdly amazing

Pretty easy to use, good weight figuring theres probably (4) 18650 batteries in it with the control board.

Also used the battery pack thru out the day charging a wireless speaker and when I got home to plug it in to recharge the battery pack it had only lost 1 bar of fully charged.

The best battery for the price is the better the quality is good.

Another bonus, this battery holds its charge for a long time without draining.

Best portable battery ever, it has a lot of power capacity

Great battery life and charges my devices fast!

I got one use out of it before it started leaking battery acid which us corrosive.

Cheap crappy battery

I’ve had this battery for three years now and it still works great

Really liked this battery for about two weeks until it CAUGHT ON FIRE while charging

Very decent battery

Excellent, long battery life

strong battery life a bit heavy though

so don't drain all your battery in that before plugging it in

This is a great battery and has an excellent price

Even though it’s on the larger side it has great battery life

This is a good portable charger with great battery life

Big fat battery.

Saved me many times on my old phone with bad battery in very important situations

I'm glad this was not an expensive battery pack, because it has been useless.

It's a little heavy, but as expected with a battery pack like this

It worked just like advertised till the battery completely failed a few months ago, I think due to the abruptness of the failure it was just a faulty battery

Battery doesn't last long..worked great for the first month but after its only good for one charge

Amazing how many people either have bad batteries or don't charge their phones before going out.

Great battery for the price

This portable battery sure was helpful

Great portable battery with amazing storage capacity.

Quick delivery, battery is better than I expected

When I disconnect my phone from this battery, the battery gets completely drained even if It was fully charged right before I disconnect my iphone from it

Very cheap and amazing battery

This has been a great battery pack so far

Good battery charger.

This is a great battery pack for older devices and has saved my bacon multiple times on long travel days

Unlike other portable batteries, this one doesn't seem to leak too much power

it works especially my son would be watching, it helps for extra charge when battery is dead and no outlet available.

Have owned this battery for almost 4 years (Aug 2014 - Jun 2018) before it finally died on me last week.

While using this power bank, I actually still lose battery if I am using the tablet

I bought this charger because my phone's battery is really bad, so when I have to spend all day walking or doing something outside my house my phone always end up dying

You will not find a better battery pack for the price

and I told my co worker my battery is going to die soon

: This is an AWESOME battery pack for the price.

Its a little bulky but its the best portable battery I've ever owned

This battery has served me well so far

then the battery drains very quickly (like when charging two devices at the same time or in rapid succession)

Great battery back up

Also when it charges, it never tells me when the charge is complete , the 4 th LEDs should stop flashing but it never does and the battery gets so hot that I am afraid it will get on fire.

Although this works VERY well and charges your phone quickly for hours, it completely KILLED my actual battery in the phone and i had to go buy a new one.

Good battery life

The battery is great i can charge multiple Devices, The battery last long always got it with me

This battery solves that problem

These are great battery banks.

Good battery life and the 2 USB plugs allow charging of 2 devices simultaneously

Not bad for an inexpensive backup battery.

This is a great battery pack.

I'd recommend spending a few more bucks for a more reliable battery.

Very compact, very powerful rechargeable battery

I was looking for a cheap battery to charge my Galaxy S6 during my trip to Europe

Excellent battery

This product started leaking battery acid from the creases and ruined my headphones that was in the same bag with it

Pretty amazing little battery pack for the price at the time

Great battery

The batteries must be inferior.

Only thing she uses it like crazy and depletes the battery and it take about 6 hours to recharge.

When I used my car again I looked at it, thinking the battery may have drained but low and behold it was fully charged

Well, this battery is officially DOA.

I've bought a lot of portable batteries from here...generally when they were the deal of the day and seemed like a good deal.
