♦ size: 4.25" x 7.125" x 0.375"
♦ weight: 11.3 oz
♦ number of ports: 2
♦ flashlight: no
♦ pass through charging: yes (i.e. the battery can charge while being charged itself)
♦ cables: 1 charging cable
♦ Special note: to turn on this power bank you need to swipe your finger from left to right over the two lock icons
This a nice looking battery, its finish makes it look like a leather bound notebook. To turn it on you need to swipe a finger left to right over the charger level indicator. This battery's capacity is 15000 mAh. I charged a totally discharged Hyperion 3800mAh Extended Battery to 100% in less than 3 hours and the charge indicator went from 4 lights to 3 lights.
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. 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 one that do not perform well. Note that these tests are not testing for the maximum current each device can draw on each port.
I also tested to see if the battery supports pass-through charging (i.e. whether the battery can charge mobile devices while it is being charged). This battery supports charge through charging. It can not charge while being charged.
Samsung Nexus phone:
~~~~~~~~~~~~~~~~~~~
port 1: 0.98A/5.05V (excellent comparing the performance of the same device with other chargers)
port 2: 1.00A/5.06V (excellent comparing the performance of the same device with other chargers)
(for comparison the best charging monitor result for this phone is 1.00A/5V)
Note: these tests are not designed to test the maximum capacity of the port
iPad Mini tablet:
~~~~~~~~~~~~~~~~~~~
port 1: 0.93/5.08V (average for 1A port for the same device with other chargers)
port 2: 1.23A/5.10V (good 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, some of the battery capacity is always lost to heat, voltage conversion, and operation of the power bank itself. I always estimate that 30% of the capacity will not be available for the charging of the device.
