Product review: iPowerBuddy 10000mah Dual Port USB Portable Charger External Battery Pack

video

This is a 10,000 mAh external battery with two ports and a flashlight. The flashlight is fairly bright but generates a narrow beam (see video). The power pack has a very nice and clear charge level indicator - a digital display with the amount of remaining power. The charger performed well with my Android phone but charged iPad Mini at 1 amp rate on both ports including the port rated as 2.1 amps.

Size: 5 3/8" x 2 1/2" x 3/4"
Weight: 7.9 oz
Capacity: 10,000 mAh
Charge through charging: no (i.e. can charge while being charged)

To see how well different external batteries charge my mobile devices I use a Nexus phone and an iPadMini to test each of them. The current drawn on each port depends on each device using the charger. The port rated with a 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 various chargers 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 because I do not own devices that can max out the current draw.

I am including the details of the tests below for those who like to see the technical details.

★ Test Results:
======================

✔ Samsung Galaxy Nexus Phone
--------------------------
port 1: 0.94A / 5.01V (good)
port 2: 1.04A / 5.01V (excellent)
(for comparison the best charging monitor result for this phone is 1.00A/5V)

✔ iPadMini
--------------------------
port 1: 0.93A / 5.01V (typical for 1A port)
port 2: 0.94A / 5.01V (typical for 1A port)
(for comparison the best charging monitor result for this tablet is 1.70A/5V)

★ Summary
------------------
This battery performed best with Android devices.
