- - - Overview - - -

Many brands to choose from. Prices are bouncy and coming down.

This 8400 mAh model is enough to charge your iPhone 3-4 times, your iPad-2 80%, or your iPad-3 40%. Tablet users may want larger. (Note 1 explains mAh)

They're not forever. Usually rated for 500 charge cycles, but they can die much sooner. Warranty and customer service matter.

You can save money by waiting for price dips. There's an "Online Price Alert" that will email you whenever this or any amazon product dips below your target price. Google it. Or try camelcamelcamel.

The manufacturer gave me this product for review. I believe my review is impartial.

- - - About the PowerGen 8400mAh - - -

After checking it out for a month, I'd say this is a solid product, probably comparable to the alternatives listed below.

PROs:

- 1 year warranty (see comparison below)
- Charges iPhone 3-4 times at full speed (see Note 2)
- Fit and finish are very good
- Power-in is a standard Micro-USB connector. (Use substitute cords of any length, and any AC adapter. Some other brands have a round power-in jack with dedicated AC adapter.)

OKs:

- Capacity 8400 mAh: Great for smartphones. Tablet users may want more.
- Reliability: New model, but the identical Anker 8400 has been out for 1+ year with few Amazon review gripes. Mine had a bad cable (which i didn't plan to use anyway -- see Note 3).
- 2 outputs: 0.6 Amps and 2 Amps (markings are hard to read)
- Comes with a 7-piece interconnect system for most devices. I'd leave it in the box and use regular cables instead (see Note 3).

I had been looking for an external/additional battery pack that was hefty enough to power/charge multiple devices from a single charge. I had seen some of the other more bulky versions (usually catering to the mobile computing crowd), but I didnt want to spend an arm and a leg and I definitely didnt want to carry around a huge brick. After weighing my options I decided to take a look at the PowerGen 8400mah High Capacity Power Bank.

Looking at the images, I liked the size. It was definitely smaller than I had anticipated for something that offered so much capacity. The fact that it was 8400mah and not something around 5000-6000mah was also a major selling point for me. The cost was right as well. I had previously bought the 2900mah Mobile Juice Pack (which is smaller, but at only 1/3 of the capacity) and that worked great for my personal use and keeping my Samsung Galaxy S II powered all day. But to keep a couple iPads, an iPhone, and my S II powered up? I definitely needed the 8400mah.

My order arrived quickly and well on time for a trip to New York. I coupled the Power Bank with a PowerGen Dual Port USB wall charger PowerGen Dual Port USB 2.1A 10W AC / Travel / Wall Charger for Apple iPad 2, New iPad 3, iPhone 4 4s 3Gs 3G, iPod Touch And More Devices (USB Cable not included) - Black. I wanted a dual port to cut down on the number of wall plugs I was packing. Another one of the reviewers also mentioned that using a 2A wall plug allowed the 8400mah Power Bank to charge quicker. So that was an added bonus (although I never compared the wall plug it came with versus the 2A wall plug).

If you travel or are a power user of electronic devices you know how frustrating it can be when your mobile phone or tablet is done for the day and your work isn't. This powerful but compact battery pack is ideal to completely recharge your phone or extend your working time on your tablet. It is small enough to slip into your pocket or drop into your purse or briefcase. Weighing only 6 3/8 ounces you will not even notice that you are carrying it. It is powerful enough to recharge your iPhone (for example) up to 4 times or extend the operating time of your iPad for 40 to 80 percent depending on the model you are using. Flying in a plane, riding on the train or bus or sitting in the park you can plug in and power up.

The Juice Pack has an LED flashlight for emergencies, use in a hotel room or simply finding a seat in a dark theater. The LED flashlight can operate for up to 380 hours on a full charge. When my unit arrived it was charged to 3 LED's or about 75%. Using the included AC wall adapter I charged the unit and in about 2 hours I was ready to begin my testing. You can also use your other AC wall chargers like the one that came with your iPad 3 which has a 2 Amp output and it will charge the battery pack much faster than the 1 amp AC wall charger that comes with the unit. You can also charge the Juice Pack with your computer's USB port but just remember that most computers can only output USB currents up to 500 mA. That is 1/2 of the power of the supplied AC wall adapter and ¼ of the amperage of an iPad wall adapter which is rated at 2.1 Amps. Using your computer may take up to 18 to 20 hours.

The battery pack is beautifully designed and solid. With 2 USB ports you can actually charge two devices simultaneously.
