Product review: ROMOSS Sense 6 Plus 20000mAh Portable External Power Bank

' size: 6 1/4" x 3 1/8" x 7/8"
' weight: 16.85 oz
' number of ports: 2 ports
' flashlight: no
' cables: 1 charging cable

This external battery performed very well (1.36A/5.01V) on 2A port with my iPad Mini, the second port is 1A and it showed typical performance for this tablet on 1A drawing 0.93A/5.00V (this is below optimal, but normal for 1A port).
My Nexus phone drew only USB rate on 2A port (0.42A/5.00V), and below average on 1A (0.89A/5.01V).

To see how well different chargers and external batteries charge my mobile devices I use a Nexus phone and an iPadMini to test each of them. The current drawn from the battery depends on each device using the battery. The port rated with maximum capacity of 2A does not always deliver 2A, what is actually delivered is controlled by the device based on many factors such running apps, level of charge, and so forth. I always use the same two devices and I do my tests with the devices charged to the same level, running the same applications and using the same cables to keep everything the same. This allows me to do a relative comparison of each battery and identify the ones that do not perform well. Note that these tests are not testing for the maximum current each device can draw on each port as neither of my devices can max out the port.

I check if the cable that came with the battery is a charging cable (i.e. capable of charging at full AC rate or if charges at slower USB rate). This is easy to tell by using a current monitor and I happy to report that this package includes a charging cable that works at AC rate.

The best feature of this battery is the large capacity. Given that it is not a fast charger my main use for this battery is to have it power my my MP3 speaker with external speaker. I use it a lot and normally need to switch the external power pack every day, but using this battery I can go for several days without a swap.

You can find it on Amazon by following this link.
