5.0 out of 5 stars Great Product October 20, 2010
Verified Purchase
I have had this product in my hands for a few days now and have used it to charge my Nexus One and an iPod Touch. The product itself comes with adapters for three different types of USB including Apple 30-pin, Micro and Mini. I don't use the mini that much but I do use the 30-pin and micro quite often to charge my various Apple devices and my phone. Because the battery has a 5000mAh charge it works great for my long days that I often spend going from work to school with little time in-between. I recommend this product for anyone that spends time away from a wall outlet or just wants an extra backup battery.

4.0 out of 5 stars External Charger January 22, 2011
By eDuBB
Verified Purchase
Works as advertised, purchased ahead of a 14 hour flight to Japan to charge Nook Color and iPod during flight. Charges both from dead at least 1x along with numerous partial charges. Of note, on Nook Color, the device does not acknowledge the external battery however, does charge. The same is true for an iPad, it will say "Not Charging" but charges, albeit slowly which works for me. Good device if you are traveling with an iPhone, iPad, Nook Color, or other usb chargable device.

5.0 out of 5 stars Cool gizmo March 18, 2011
Verified Purchase
I was looking for a battery pack to charge my Nook Color. Did try Trans4m Travel Charger earlier which said it could charge Nook ereaders, but it didn't do the job. I guess they meant the classic Nook, not the Nook color. Anyway, the ClearMax CM-500 works just fine. Please note, the nook does not display the 'charging' status, but it does charge nevertheless. I've not charged the NC from 0 to full with the clearmax yet, but I believe it can be charged to full capacity at least once, if not more. Great product to have, especially if you are planning to use your Nook color during a long international flight.

1.0 out of 5 stars Major Limitations March 26, 2011
Verified Purchase
Standard USB Port to connect to for charging your device but they felt the need to switch the polarity of the connections so that you must use the 3 adapters they provide you with but if you have your own USB Cable, like the one for the Blackberry 9780 or the older blackberry's or any Apple "i" products, your products won't charge.

Very very very cheap and crappy marketing and it is being provided as nameless and a variety of names but the same idea.

With no availability of different adapters or replacement of the "1 main cable provided for both the recharging of the device and for charging of your cell phone etc" it has a very limited life!

5.0 out of 5 stars Very Good External Battery Pack - Highly Recommended December 27, 2012
This Clearmax 5000mAh External Battery Pack works well and is very handy to have along on long car trips. We have several of these types of battery packs and they have become indispensable since we are a very gadget heavy family. Here are my observations:

Pros -
+ Design; relatively compact and good looking
+ USB Port Cover; this is a nice feature that keeps lint out of the USB port when being carried in a pocket or purse
+ Connectors; comes with a retractable USB cable and heads for Apple (30-pin) iPod/iPhone, mini-USB, and micro-USB
+ Power; worked well to charge my HTC EVO 4G, iPod Touch, iPhone 4, and Kindle Fire
+ Indicators; uses three red LEDs to show current charge

Cons -
- No Carrying Case/Bag; you will likely need something to carry the cables and heads with the battery pack
- Proprietary Charging Cable; you have to charge the battery pack with the included retractable cable

It should be noted that one of the earlier reviews erroneously states that the USB port has reversed polarity and you can not use your own USB cable to power your device. This is simply not accurate, and I was able to use my own cables without any issue.

Highly Recommended!

5.0 out of 5 stars amazing back up November 19, 2012
Verified Purchase
I had been to Barns and Noble and asked if there was any back up battery for my Nook Color. I do a lot of traveling on long flights and needed a longer lasting battery. There comment was that there was "nothing" out there. I did a search on amazon and found this product and the review comments said that it worked well for Nook Color. I ordered the product, recieved it within two days. It works beautifully to extend the battery time on my Nook, and I am extremely pleased.

5.0 out of 5 stars highly recommended for oversea trips January 3, 2011
Verified Purchase
i was flying from US to China on a 14hr flight and i was worried about my iPhone. The plane that I was taking did not have any power ports under the seats. I already owned a Dexim 2650mAH battery charger that can fully charge my iPhone one time only. I did some research online and found this unit and 5000mAH is well enough for 3-4 recharges. I highly recommend this unit. I wish it was more form factored to the iPhone width though. I give this device a 5/5 stars.
