The Power Pack 4000 allows you to charge two devices at the same time, which is great.
S. Brooks
I understand that to charge the Power Pack via USB would take longer, but I would really like to have the option to charge it that way.
T Austin
When it needed a recharge after several hours, the light and handy Belkin was there to do the job and still powered up and ready to go.

Gadgets are all around us today - from tiny music players to GPS navigators to cell phones to bluetooth headsets to the latest tablet computers... and the one thing they all have in common is they all need power. I know it's happened to me, and I'm sure it may have happened to you - you need to charge that phone or your bluetooth headset or you're on a plane and your shiny new tablet is running low on power and you don't have the charger or even if you do, you have no place to plug it in! Well, this may be a helpful item for you. This compact, lightweight battery pack carries 4000mAh of portable power. That's enough to fully charge my power hungry BlackBerry Bold 9700 over two times. It supplies it's power through two standard USB ports - and you can use them both simultaneously. I've already used it to charge both my Cowon S9 and my BlackBerry Bold 9700 at the same time! I also used it to power my HP TouchPad last night when it's battery was getting low - the Belkin didn't have enough power to flat out charge the TouchPad, but it could run off this external battery for hours. For most devices I use today, plugging into this portable battery is the same as plugging them into their charger. The important thing to consider is that this device supplies USB power. So if your phone or GPS or bluetooth or whatever has a mini or micro USB plug, you can likely power it or charge it from this battery.Read more ›

Vine Customer Review of Free Product ( What's this? )
This device proved itself to be very useful and showed that it works quite well. I charged it as the instructions say for 8 hours before first use, and then it takes about 3 hours to charge after that. It has 4 blue LEDs on it that blink and when all 4 are solid that indicates a full charge. As it decreases the amount of lit LEDs drop so you are always aware of how much charge the device is holding. This is a good indication function. It is charged by using the AC power cord that comes with it, and it also has 2 USB cables with different size ends on them for use on devices that have different sized charging inputs on them.
I took it with me when I was out with my 2 nephews when they visited. One of them has a Metro PCS phone that he texts constantly on, and the other has an iPod that is attached to him at all times. I was able to use the Belkin 4000 to not only recharge both those devices but my Kodak Easy Share M580 digital camera as well during our day out. Now the devices were not at total dead battery, but very low, and the Belkin boosted them all up for use for the entire day. Having this saved the trouble of needing 3 separate power cords and use of an AC outlet. Also the Belkin has 2 USB charging outputs so you can charge 2 separate devices at the same time, which is also a plus as this eliminated them fighting over who was gonna get their device charged first and who would have to wait. Not having to listen to 2 teenagers fighting is a blessing in itself.
Also the size of the device is good, it is small enough to travel easily yet not so small it can be misplaced by accident.

I was recently gifted an iPod Touch which I soon discovered drains its battery fairly quickly. So it was perfect timing when I was able to snag one of these a few days later. On the packaging it claims to provide 4 cell phone charges or 2 smart phone charges. Here are the results I got:

1) iPod Touch charged from 20%->100%
2) iPod Nano charged from 0%->100%
3) iPod Touch charged from 0%->100%
4) iPod Touch charged from 15%->50%

At that point the Power Pack finally ran out of juice. So it does deliver as promised.

It's very compact, only marginally bigger than an iPhone 4. That makes it ideal for tossing into a backpack and carrying around for spare power. It has a nice black matted finish. I forgot to time it exactly, but it took roughly 3 hours to fully charge. As another reviewer noted, the power adapter is pretty large. It has a simple 4 led display which displays the power level. It's usually best to press the reset button when plugging in a device for charging. Sometimes it starts charging as soon as I plug in a device, other times I need to press the button first.

The one downside is that it is rather expensive compared to the competition. I haven't tried other brands, but there are alternatives that have very high ratings and cost significantly less. If it were priced more competitively, I would definitely give it 5-stars.

Update 10/22
I've noticed that the LEDs which indicate battery power aren't real accurate when the device is in use. When I plug in my iPod I often get 3-4 bars, indicating it is mostly full. But then it dies relatively soon. When I plug it back in to recharge, it shows it is charging from 1 bar, indicating I had drained it completely. This doesn't affect the runtime as it still seems to be giving me the appropriate amount of charge, I just can't depend on the indicator to accurately reflect the amount of power left.
