Product review: Jackery Titan Premium Travel Charger 18000mAh

















' size: 5 7/8" x 3 1/4" x 3/4"
' weight: 15.65 oz
' number of ports: 2 ports
' flashlight: no
' cables: 1 charging cable

This external battery performed pretty well for charging both my Android phone and Apple iPadMini tablet. iPad Mini performed in line with the best external batteries I have tried, and Nexus phone did very well on one port and slightly worse on the second port.

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.

Samsung Nexus phone:
~~~~~~~~~~~~~~~~~~~
port 1: 1.00A / 5.05V (excellent comparing the performance of the same device with other chargers)
port 2: 0.84A / 5.01V (below the best, but above USB rate)
(for comparison the best charging monitor result for this phone is 1.00A/5V)

As noted above these tests are not designed to test the maximum capacity of the port, so 2A port not showing 2A is not an indication of a problem

iPad Mini tablet:
~~~~~~~~~~~~~~~~~~~
port 1: 0.83A / 5.00V (typical for 1 A port)
port 2: 1.43A / 5.09V (excellent comparing the performance of the same device with other chargers)
(for comparison the best charging monitor result for this tablet is 1.70A/5V)

The battery has a nice capacity and fast charging rate for both Android and Apple devices
