Product review: Bolse® M3 6600mAh Dual Port External Battery Pack

I tested Bolse M3 (6600 mAh) Power Pack with Samsung Galaxy 7.7 Tablet (running ICS 4.0.4) and iPad Mini. It showed exceptionally good behavior with iPad Mini and average performance with Galaxy Tablet.

I received this power bank from the manufacturer 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.

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.
