I received this power bank from the manufacture for an honest review be it positive or negative. One of the benefits of being requested 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.
These comparison tests reveal that Sendy power bank works very well with Android devices (particularly the Galaxy Tab which is often the worst performer), but did NOT work with my iPad Mini.
The size of the power bank is 4" x 1.75" x 0.75". It weight 4.5 oz on my digital scale. In addition to being a charge it also has a built-in LED light. The light is not very bright, but better than nothing in an emergency situation.
My methodology for testing power banks is to charge each mobile device for 10 minutes and measuring how much each unit was charged in that 10 minute period. 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.
✔ Nexus 7 Tablet
--------------
Charging cable -- AC ............. 1% change in charge in 10 minutes
✔ Samsung Galaxy Nexus Phone
--------------------------
Charging cable -- AC ............. 4% change in charge in 10 minutes
Data cable ------ AC ............. 1% change in charge in 10 minutes
✔ Samsung Galaxy Tablet 7.7
--------------------------
Charging cable -- AC ............. 5% change in charge in 10 minutes
✔ iPad Mini
--------------------------
iPad Mini cable -- power source not recognized ............. 1% dischage in 10 minutes
✔ Sansa Clip+ MP3
--------------------------
When I charge Sansa MP3 with a standard AC charger, the MP3 player goes into charging mode, displaying the charging animated icon. When it is plugged into the Sendy power bank the MP3 continued to play the content. This is a great benefit for MP3 player with built-in battery, this means I charge and listen at the same time and I do not have to wait for the battery to recharge.
I am attaching a collage of 4 photos, which can be located by following 'customer photos' link under the main photo:
Photo #1 shows everything that came in the package, USB cable with interchangeable tips and a small bag for carrying the power bank.
Photo #2 shows the power bank next to Sansa MP3 player for size reference
Photo #3 shows Galaxy Tab with the battery app showing results
Photo #4 shows iPad Mini which did not recognize the power shot (when it does a white plug icon is displayed on the app screen)
Overall:
------------------
Excellent performance for Android devices, does not work with iPad Mini. Nice size for travel.
