Product review: iFlash 5600mAh Backup External Battery Source

I tested iFlash® 5600mAh External Battery Pack with Samsung Galaxy 7.7 Tablet (running ICS 4.0.4) and iPad Mini.

I received this power bank from the manufacture for an honest review be it positive or negative. Top reviewers are often asked to review new battery packs and one of the benefits of being asked to test different power banks is that it gives me an opportunity to compare them to each other using the same charging test, so I can compare them using "apples to apples" comparison. This set of tests allows me to provide unbiased results as the numbers speak for the performance of each unit.

I received two identical units black and blue, having two of them allows me to test for consistency in manufacturing. Ideally I want to see the same performance numbers for both units when testing the same device, and this was the case with these two units.

My methodology is to charge each mobile device on each port of the unit for 10 minutes and measuring how much each unit was charge in that 10 minute period. In addition I tested charging two mobile devices at the same time. Each line in the table below represents a separate 10 minute test. I use Battery App by Elvison to determine how each device recognized the charging source. 'AC' status means the charging is at full charging rate. 'USB' status indicates charging at a lower charging rate. 'Discharging' status means that the charging rate is below the power that the device is consuming so it slows down the discharge rate but does not re-charge.

➨ General features:

iFlash® 5600mAh external battery weighs 4.4 oz. Its size is 3.75" x1.75" x 0.875". The pack has one USB output port. It comes with a pouch which fits the power pack, cables and tips. It has a built-in flashlight.

The external battery comes with a charging cable and 5 tips - micro USB, mini USB and iPad (and two others I don't recognize). It did not have tips for Samsung Galaxy Tab or lightening connector for iPad Mini and I used my own charging cables during the tests. I am attaching a photo of Flash® 5600mAh during one of the test next to my tablet for size reference. You can find this photo by following 'customer photos' link under the main photo in this listing.

➨ Test Results:

✔ Samsung Galaxy 7.7 tablet (using my own Galaxy tab connector cable)
Blue unit: AC ~~~~~~ 2% change in charge in 10 minutes
Black unit: AC ~~~~~ 2% change in charge in 10 minutes

✔ iPad Mini tablet (using my own lightening connector cable)
Blue unit: AC ~~~~~~ -1% change in charge in 10 minutes (discharged)
Black unit: AC ~~~~~ -1% change in charge in 10 minutes (discharged)

➨ Key finding:
✔ It works well with the Galaxy 7.7 Tablet, although charging rate is not the fastest I have tested. This power pack does not work with iPad Mini. I observed the same performance for both the black and blue model, which is good and reflects consistency in the manufacturing process. Overall rating: OK.
