It is able to charge my ipad and iphone 4S at the same time.
Lloyd Winkelman
I would recommend this to anyone intersted in ensuring their cell phone doesn't go dead at a location without a power outlet, or the time to wait to find one.

This is a perfect product for anyone who travels or works long days. It is perfect for those long airline flights or just daily travel or vacation. Whether you are riding on a train or camping this battery pack will be very handy for you to have along. This powerful battery pack can charge your smart phone or extend the use of your smart tablet. It is beautifully designed, small and portable. It uses high grade 18650 power cells which will provide years of recharging capability. These are the same style of batteries used in many portable computer battery packs.

What I like is that the unit is priced well and it is small and portable but can really carry a lot of power (8400 mAh). You could recharge most smart phones from 2 and up to 4+ times with this power cell. I have included a video of this review and I hope it is helpful to you. It is powerful enough to even give a boost to your electronic tablet devices. It weighs in at 7 ¼ ounces and it is smaller in size than your iPhone shape but it is thicker. It will still easy fit into a purse, briefcase, computer case or even a pocket. Don't forget your connection cables.

Please note that the unit comes with one cable and you can charge the battery with your PC or with a wall AC adapter. A wall adapter will charge the battery pack twice as fast at 1 Ampere DC because your computer's USB port is limited to 500 mADC. The charging port requires a USB micro-B connector that comes with the unit. If you use a 2.1 Amp rated wall charger then it will charge 4 times faster than using your computer. Please see my notes on my charging results.

The output current to charge your devices is up to 2.1 Ampere. It has two USB output ports and you can charge two devices at one time.

This is a power unit that holds a lot of juice for many portable devices.

It comes with the unit, a USB cord with an open plug, and a series of plugs to connect to your device - iPod/iPad, micro USB, mini USB and 2mm round. It took awhile to get this charged up plugging the provided USB cable into my USB wall charger. You have the option of charging it with your computer as well. I think it was at least 10 hours of charge time but I eventually went to sleep and it was fully charged in the morning so I'm not sure when it hit its peak.

It has two USB ports and one input micro USB port to flip your cable for charging the unit. There is an easy power button with three light indicator for remaining power on the unit. Three lights indicate more than 80% power remains, two lights mean 30-80% and one light means less than 30% power remains. I wish there were actually four light indicators but three will do.

The unit has a solid feel. I used it to charge a 30% battery level Droid Incredible 4G, which took about 80 minutes to charge fully. I also used it to take a 17% Kindle Fire to full battery power in just over an hour. It sill had two out of three charge lights available. I then charged an iPod classic with about 50% power left and that was about the time it needed recharging.

I was impressed with how quickly it charged these devices.

If you've ever run out somewhere and forgot to fully charge a device, you know how convenient it is to have something like this in your briefcase. If you have ever been caught in a power outage, you know how frustrating it is to get to a power source to charge what is probably your only form of communication for awhile.

It would have been nice to have a carry bag or pouch to contain the unit, cable and tips but it's easy enough to find something in my closet.

I was provided a unit for testing and evaluation.

The Yubi Power 8400mah battery pack is the perfect size battery pack for people who are looking for a large battery pack but want the portability of a smaller one. This battery pack features 2 USB ports on the front with micro USB port for charging the battery pack. It has a 3 LED power level gauge that tells you how much power is left above the power button. It also has a LED below the power button to tell you that it is on and ready to charge a device. It has a black glossy finish and a mirror like surface on top where the power button is. It does attract fingerprints easily. This battery pack is great to have especially if you want your smartphone last about 3-4 days. I like this battery pack because it is small and packs a lot of power to last a device a long time on the road.
Overall, this battery pack is great and I recommend it to anyone who want a lot of extra power that is portable.
Overall, this battery pack is phenomenal and I recommend this to anyone who wants the extra power.

I was supplied a sample for test and evaluation, and I promised that my review is fair and honest.

This is a nice shiny silver and black battery system the size of a pack of cigarettes with two USB ports and a proprietary tiny USB ends (for the battery pack); and a standard AC power adapter for USB to electrical outlet. Three tiny blue LED lights show you the level of power inside.

The entire 8400mAh battery pack FULLY charges in about 90 minutes (via AC adapter); more with the USB port on your computer. There is a port input for the small USB plug for charging and two regular sized USB female plugs for charging other devices. The most enticing thing about this `power bank' is that not only can it charge two devices at once, but it will charge your iPhone 4 and 5; (4-5 charges total).

Also will charge your IPad, IPad 2, IPod; Android (Samsung Galaxy Note S S2 S3) and others with the included adapters. Many external batteries will NOT do that. 8400mAh is a lot of battery power. That number is the secret to buying a powerful battery. This product was generously supplied by the manufacturer for an honest review.
