4 out of 5 eggsBig Not pocket friendly

This review is from: Power Walker EnerKing Rechargeable USB Power Bank K12500 - 12500mAh 1A/2.1A Dual Output Max Total 3.1A Output (Black)

Pros: 12500 mAh thats alot of juice I charged mine and my wife's S3 to 100% at the same time. did not take long at all.

Cons: will not charge my Asus Transformer tablet it needs 15v in and this power pack only outputs 5V on both ports one at 2a and the other at 3a. it says it can charge tablets. I am sure with my tablet off it might trickle charge it. I might be able to go 2USB to one and make it 10v and it might work enough for the plane trips.

4 out of 5 eggsBe careful with DC IN port

This review is from: Power Walker EnerKing Rechargeable USB Power Bank K12500 - 12500mAh 1A/2.1A Dual Output Max Total 3.1A Output (Black)

Pros: 12,500mah Wow! This battery will charge my Samsung Galaxy S3 fully, and still have lots of power left over for a second or third charge.

Cons: My unit was purchased 02/17/2013, and on 04/20/2013 my "DC IN" port was loose. Sadly 04/21/2013 it broke and is now rattling inside the unit (Dont know if it was workmanship or something I did). Yes...that means I can not charge my unit any more :-( . In the process of trying to contacting Powerex....it is under warranty.

This review is from: Power Walker EnerKing Rechargeable USB Power Bank K12500 - 12500mAh 1A/2.1A Dual Output Max Total 3.1A Output (Black)

Pros: 12,500 mAh of power. Great for long plane rides where there's no place to recharge your iPad/iPhone.

Cons: None so far.

Other Thoughts: I got lucky on this one. Got it when it was on sale for only $40. Very handy gadget.

4 out of 5 eggsShes a Brick House!!!

This review is from: Power Walker EnerKing Rechargeable USB Power Bank K12500 - 12500mAh 1A/2.1A Dual Output Max Total 3.1A Output (Black)

Pros: So as other reviewers have stated this thing is pretty dam beefy. I charged one up and have placed it in the center console of my care with a line out. (my car charger is broken) I have been recharging my Note 2 phone for a couple days and its still got alot of juice left so once it runs low i will swapp it with the second brick and rechage this one up.

Cons: I didnt pay attention to the dimensions of this thing and was expecting something a bit smaller more pocket friendly. However this is mostly my own fault for not paying attention to that small detail.

Other Thoughts: Overall i am pretty happy with these units. Hopefully they will last me a couple years in the rotation i plan to use them in.

5 out of 5 eggsGreat

This review is from: Power Walker EnerKing Rechargeable USB Power Bank K12500 - 12500mAh 1A/2.1A Dual Output Max Total 3.1A Output (Black)

Pros: WOW! 12,500mAh! WOW!

Cons: Not really a CON for me...But yeah it's kind of big (I keep it in my SwissGear bag) , but its size makes up for what it is CAPABLE of doing.

Other Thoughts: Keeps my Samsung Galaxy S3 going. Yeah Mugen Power Batteries has an extended battery for the Galaxy S3, but no protective case....not really feeling the product from Sedio.
