Product review: Jackery Crew 5-Port High Speed USB Charging Hub
' size: 2 1/2" x 3 3/4" x 1 1/8"
' weight: 6 oz
' number of ports: 5 ports
' cables: AC port is 54.5"
The best chargers have a smart chip in them which charges all devices to their optimal charge on every port. This charger does not have this chip. This charger performs very well for my Apple iPadMini tablet. For Android phone it works, but does not charge the phone as fast as other chargers. I captured results of the tests in attached photos for those who are interested in the details of the tests.
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 charger 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 none of my devices can max out the ports.
In addition to testing the devices individually, I tested to see if the charger is capable of charging 5 devices at the same time (2 phones and 3 tablets). I monitored each device with the current monitor and I saw that each devices was drawing the same amount of current when it was the only device charging as when it was one of 5 devices charging. This is good.
