Pros: I have had this thing for almost a year and it works great. We used it several times when we went to the lake to maintain our cell phones. I charged 3 iPhone 5/5c's from less than 5% on each phone and still had juice left. I have not ran it all the way down yet.

Cons: It takes a really long time to charge but a long time to discharge as well so the trade off is good.

Other Thoughts: I got it on special for less than $30, not it is $89 ouch.

Pros: solid, great design, fast charges my nexus 6p which was completely unexpected.

Cons: none

Other Thoughts: I have had other brands that ended up being shoddy and losing power immediately.

Pros: great pack. gives me 4 full charges on the s4 and s5 samsung cell phones. full charge in less than an hour using the 2amp connection. easily charges 2 devices.

Cons: carrying pouch needs to be a little larger to hold all the cables.

Pros: I have had several powerbanks and none better than this! I have an iphone and can charge it up to as many as five times maybe more before it dies. It is larger in person than it appears but it is amazing and i love the carrying ouch it comes with. Also nice deal for $22 on sale :) thank you!

Cons: None

Pros: Works great to charge one or two devices at once. Solid performer at charging almost all devices. I have used it to charge: Blackberry, IPad, IPod Touch, Samsung S3, bicycle lights, bike computer.
Lots of battery power.
Bought on sale, I thought it was a great deal for the amount of power.

Cons: Will not charge my ASUS transformer.
Can not charge the RavPower battery and your phone at the same time (at least I couldn't get it to).
No AC charger, must charge the RavPower from your computer or other USB wall charger.
Instructions are not great.

Other Thoughts: This is a rather large and heavy battery, but it's also 14000 mAh. I don't know if I'd call it portable - it's a bit too big to walk around with. I took it camping and it worked great.

Sometimes when you plug in your phone to charge it doesn't automatically start charging it, but pushing the button always starts the charging.

The flash light is a bit gimmicky. Some reviews say it never worked. Mine did work.

Pros: I got two, one for my wife, one for me. we both use Galaxy S-4s curly, I also have the galaxy tab 7. My wife can charge her phone 3-4 times from dead, or keep a full charge all day at Disney on her phone. I've charged my phone and tablet from completely drained twice (each) before having to recharge it.

Cons: It does get warm once in a while when charging, but little to worry over.

Pros: the kid loves it works great

Cons: n/a

Pros: Excellent capacity, simple effective design. Takes a couple hours to charge but can recharge my cell 4 times, keeping me going for a week.

Cons: Shorter provided cable is starting to fail at the connector. Have to hold it a certain way to charge. This is minor as I have a much more durable cable I use, but knocks off 1egg.

Other Thoughts: The flashlight is kinda unwieldy on a device this large and could have done without.

Pros: Good for charging one cell phone for one time only. You have to charge it use again.
easy to carry.

Cons: Battery will not last for 1 day.
Have to charge it every day
it takes 12-15 hours (Overnight) to fully charge up.
USB cable of filth quality. Rubber covering on USB cable easily comes out.

Other Thoughts: I was using this mobile charger for more than 6 months,battery does not last more than 1-2 days. I was excited after reading the reviews, and bought it and i recommended for my friend. Neither I am nor my friend is happy with this charger. This charger charges my samsung galaxy s 4 in 15-25 minutes. It takes overnight (10-12hrs) to fully charge the battery.

Pros: Enough capacity for multiple devices, 2.4 AMP speed available, multiple devices charge at the same time, smooth design fits in pocket

Cons: 1AMP charge on one USB

Other Thoughts: This is a great powerbank to have with you on travel. I look forward to the next flight I take and not have to be tied to a wall outlet waiting, or having my tablet die mid-flight (or mid-movie).

I have an LG G2 (3000 mAh) and an LG G Pad 8.3 (4,600 mAh) and with this RAVPower power bank I'm able to:

A. Charge my tablet twice and my phone once, or...
B. Charge my phone 3 Times and my tablet once, or...
C. Charge my phone 4 times, or...
D. Charge my tablet 3 times.

...and still have some juice left over for a Bluetooth speaker.

The only con I have is that one of the ports is maximum 1AMP. Both of my devices take up to 1.8AMP so this slows the charge rate on of the devices significanlty. It will still charge, just not while I'm using it and slower.
