Pros: I like that it has both a 1A and 2.4A outlet. I use it to charge a smartphone and can get about 10-12 nightly charges out of one before recharging.

Cons: None

Other Thoughts: I alternate between this one and another RAVPower Deluxe unit.

Pros: 2 Cell phone Full Charge
Stylish
Sturdy
Well built
Flashlight

Cons: Don't know why but doesn't charge Ps4 controller

Pros: Seems well built unit.

Cons: - Little bulky, size of a portable hard drive
- using the charger with a new Galaxy S6 complains about "slow charging" and "user original charger".
- Estimated time to charge my S6 with this power pack: (14000 mAH with either 1A or 2A) : 2 hrs 15 minutes
- Estimated time to charge my S6 with my old DEWorld (5200 mAH) :1:20 min.

Unsure about the higher capacity and new technology

Pros: comes with a neat carrying case, two cables, as well as a bunch of different adapters
Product holds a lot of charge, can charge two USB devices, flashlight

Cons: A bit large and unwieldy

Other Thoughts: This product has definitely saved me a couple of times where I had to drive to unfamiliar locations (couple hours). My phone is my GPS and was at the point where it would die when half a day passed. I just keep my phone plugged into this power bank and I'm good to go.
The device also lets you know how much juice it has left (4/4 lights is full). On a two to three hour drive, I think only one of the four lights went out (3/4 still on).

It's a bit large as stated above, but that's perfectly fine with me as long as it does do its job appropriately.

Pros: Pretty, can charge two devices at the same time, high capacity, LED flashlight. charge level indicator lights, protective mesh bag.

Cons: Failed to recharge even once!

Other Thoughts: The device came charged up, and everything seemed to be looking good. We took off for our extended trip on which we were planing to rely on this battery to power our video camera on long shoots, but once the initial charge was depleted, that was it. The battery pack would not recharge... dead! The whole trip could have been a disaster were it not for the cam's battery pack performing much better than expected.

Pros: It works good. Just like it was advertised.

Cons: My wife took it. So, now I have to buy another. She travels for work and bought one of those not battery banks from one of those "we have everything useless stores". So I gave it up when she was complaining about battery life.

Other Thoughts: If your married, buy two of them.

Pros: It works pretty well. It looks and feels like a quality product. The one usb port charges pretty fast for a battery backup. I don't know why it needed a light on it but it's pretty bright.

Cons: None really.

Other Thoughts: I really wanted the black one but I got this as the super egg saver deal and the special price was only good on the white version, not a big deal but I wish they would put both colors on sale when they did it.

Pros: Two USB ports!
14000mah.
Comes with two Micro USB cords and a pretty nice carrying pouch.

Cons: Heavy but that is expected.

Other Thoughts: This device has been wonderful. I use a Windows 8.1 tablet as my 'laptop' so being able to power two devices (tablet and phone) through Micro USB has been awesome! The device [understandably] takes a while to charge but it lasts a long time to!

Pros: It charges my device quickly and is very easy to use. It sure comes in handy when you are away from home with a dead phone battery! It re-charges quickly and is ready to use again. It is small enough to fit in your purse and carry around with you.

Cons: None.

Other Thoughts: I really like this power bank. I had no problem understanding how to use it to charge my iPhone or iPad. It charged the battery back up to 100% on both devices. I also had no problem figuring out how to re-charge the power bank itself. I would recommend this power bank to my friends and family!

Pros: I have used this unit for over a year now. In fact I have ordered two more since.
It has a very large storage capacity and does an excellent job of charging.
Sturdy construction.
Extremely reliable.

Cons: None
