1 out of 5 eggsDefective

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: -Amazing potential

Cons: This is my second request for a replacement to UnU:

"I purchased the UNU Black 14000 mAh Enerpak Vault Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS on 7/30/2013 from Newegg.com. This device failed after only two charges and would no longer hold a charge. I requested a warranty replacement of this product on 12/5/13 and was shipped a second device. I have finally had occasion to use the second device shipped to me and have found it has the same defect. After only two uses the battery will hold no charge at all. Only the single blue LED on the top of the device will blink when the device is plugged in, and the remaining two LEDs will never illuminate reflecting a charge in the device. It will work at most for 20 minutes of charging."

Hopefully the next one they ship me will actually work... Time will tell. But I wouldn't recommend this to anyone.

5 out of 5 eggsUNU 1400mAh Battery Pack

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: Simple
Sleek looking
Bright power-remaining lights
Flashlight capability.
A 2.1 amp port for fast charging of tablets.
Dual ports, so two devices can be charged at the same time.
Fairly light weight (12 ounces?).
Comes with a USB cable.
1400mAh, which is enough for 6 cell charges or two fully dead tablet charges.
Relatively fast recharge of the battery. It took under 3 hours.
Flashlight is only triggered when button is depressed for about 4 seconds. That minimizes accidental turn-Ons while it's bouncing around in my pack.

Cons: Flashlight isn't bright (but it's not intended to be... it just aids in connecting wires in the dark, so it's not really a negative.
It's not water resistant (but what battery extender is??).

Other Thoughts: I purchased this battery extended for a trip to remote areas of Central America. I'm a freelance project manager and needed the power for my tablet (just incase). No one seemed to mention its size and weight. So, here it is: 5"x3"x1" and I'd guess it's about 11 ounces. I'm putting it in my backpack and didn't find it's weight objectionable. It has a solid feel to it (not frail and nothing juts-out).

5 out of 5 eggsPowerful little thing

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: With a lot of modern devices, this is almost necessary to make it through a day, or at least to mean one never must choose between having enough battery to map one's way home and listening to some music. It's small, it has a lot of power and holds it for a long time, and has a useful flashlight function built-in. I charge mine about once a week with moderate use.

Cons: It's too easy to accidentally turn the flashlight on by bumping it, which drains the battery and sometimes is embarassing. It's not always clear how much charge it has.

Other Thoughts: I've recommended this to many friends and they've all been happy with it too.

5 out of 5 eggsNever worry about not enough juice for my phone

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: I was impressed that this portable backup battery carries a 14000 mah battery capacity within a reasonable price, it is extremely powerful source to keep my usb recharged device and smartphone operating on those long work days and while I am traveling to New York. It charges my iphone really fast, and giving my iphone almost X 8 times juice, nowadays I am no longer need to worry about my phone battery because I got this little sucker to backup my phone battery.
Here is a brief merits of this product:
1. Large capacity
2. Duo USB charging ports (allowing me to charge 2 devices at the same time)
3. Durable
4. Fast Charging
5. LED flashlight
6. Portable
7. Great for trips, camping, and gift

Cons: None that I have found as of now, except it is kind heavy but bearable. I am probably doing another update of the device performance to share about this product. So far, I would recommend this product to anyone.

5 out of 5 eggsHuge reserve with a flashlight to boot

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: - large capacity
- LED flashlight

Cons: - only comes with a micro USB cable and doesn't include different tips to power your various devices
- premium price (prices vary, but at the time of this review this sells for just 89 bucks)

Other Thoughts: This is one simple lithium-ion power bank with a whooping capacity of 14,000 mAh. It includes a micro USB cable for charging the device, just use any your existing USB AC power adapter, preferably rated at least 2.1 amp for faster charging. It came with about 75% full capacity, so you can use it out of the box. The case is made of shiny black shell with both sides protected with a plastic film. Make sure to remove the films for better heat dissipation.

The LED flashlight can be turned on by pressing the power button twice, and turn off by doing the same. It is not very bright but enough to see your way in a dark hall or fumbling for lost keys in your drawers.

These kind of back-up battery solution saved me multiple times on the road when my iPhone5 runs out of juice pretty fast. My wife carry a smaller 8,000 mAh or less in her purse. For iPads and tablets, the bigger the better and the Unu Enerpak is one such powerhouse. You can in fact charge two devices at one time using the two slots. They are labeled conveniently as "Tablet" and "Smartphone", 2.1A and 1A respectedly. To determine how much juice is left in your power bank, press the power button once. Depending many blue LEDs are lit shows you if you need a recharge.

5 out of 5 eggsAmazing Backup Power Supply

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: I was impressed that this sleek design backup battery carried 14000 mah capacity to keep my usb recharged devices operating on those long work days (it did last few day if i used to charge my iphone). So far I used this battery for two weeks, and i couldn't be happier with it.

Here is the merits of this battery pack after I used for two weeks:
*Durable
*Fast Charging
*Large Capacity
* Duo USB charging ports
* Portable for (trips, camping, and shopping)
* Has a bright LED light
* Kind of heavy but is bearable
* Able to charge two devices at the same time without worrying about not enough juice.
* Reasonable price

Cons: None that I have found as of now...... I will be doing an update after 1 or 2 month to share the device performance. Now, I would recommend this product to try it.

Other Thoughts: Tonight i am having a crazy idea, where i want to study how the lithium battery arrange inside, and the chip connects with the usb outlet. Thinking of how can I adjust the output, so i would charge the phone faster. After few more minutes, i stop because I am not going to risk of my money. hahaha

5 out of 5 eggsGreat charger

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: Charge capacity
Ease of use
Charge speed
Size

Cons: Little heavy

Other Thoughts: I bought 2 of these, one for myself and one for my wife. I am super impressed with the charge that these hold. After 7 full charges (the amount of times that the instructions say you can charge a device on a single charge) my unit was still at 2/3 charge. The charger is simple to use, small enough to take anywhere and works perfect every time. I recommend these to all my friends and family. The only downside is that they are a little heavy, but it is a small gripe considering the amount of power they store.

5 out of 5 eggsBattery pack!!!

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: I recently purchased the Extreme for my brother but after trying it out once, I decided to keep it for myself. I really like the overall features and quality of the battery pack. First off, it has just a single button which you can use to do everything. Simple is nice for me since I am somewhat technically impaired. I also like that the Extreme has two charging ports so I can charge my phone and my husband’s phone at the same time. The glossy black texture is pretty sleek as well.

Cons: : I would say the biggest con of the Extreme is the weight of it. I do find it to be a little heavy and would never put it in my purse, I usually leave the Extreme in the car and use in during my hour long commute (especially in the afternoon), this way I never have to really carry it around.

Other Thoughts: I recommend charging it overnight since the battery is big and takes a while to recharge.

5 out of 5 eggsDOING GOOD JOB

This review is from: UNU Black 14000 mAh Enerpak Extreme Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS

Pros: The uNu Enerpak Extreme is really great. I am constantly traveling due to work and can be gone for up to a week at times, the Enerpak Extreme does a great job of keeping all my products charged for a couple days. At any given time I have at least a iphone and Samsung tablet on me, so the fact that the Extreme can keep these two devices going for so long is amazing. One thing that I appreciate about the Extreme is the fact that it has two input ports so I can charge both my phone and tablet at the same time. Other additional pros include a built-in flashlight and also a very easy to use single button for switching the case ON and OFF and also to check the current power levels.

Cons: I found the Extreme to be a little bit bigger than I expected, but it still has the ability to fit in a pocket, just not as easy as I had hoped.

Other Thoughts: At first I found the Enerpak Extreme to charge somewhat slowly, however, I realized that I have to charge the Enerpak with the included cable and also make sure to use the 2.1A port for extra fast charging. Doing these two things made my charging experience much faster.
