Product review: NewNow 20000mAh Power Bank Portable















This external packs turned out to be larger than I imagined from the stock photos. Its size is 5.75" x 1.75" x 0.75" and it weighs slightly over a pound. The power pack has two ports, both of them are 1A. The external pack as a small built-in flashlight. It generates a very small beam of light and is not very bright.

The external battery performed very well charging with my Android phone. It did not perform at am optimal range for IPad Mini. My current monitor showed that neither of the ports delivers over 1A, which is required for an optimal charge for Apple devices.

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 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 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 does NOT supports charge through charging. It can not charge while being charged.

Samsung Nexus phone:
~~~~~~~~~~~~~~~~~~~
port 1: 1.02A/5.05V (excellent comparing the performance of the same device with other chargers)
port 2: 1.00A/5.04V (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)

iPad Mini tablet:
~~~~~~~~~~~~~~~~~~~
Neither of the ports delivers over 1A, which is required for optimal charge for Apple devices.
port 1: 0.93A / 5.08V (average for 1A port for the same device with other chargers)
port 2: 0.93A / 5.10V (average fpr 1A port for the same device with other chargers)
(for comparison the best charging monitor result for this tablet is 1.70A/5V)

Summary:
' size: 5.75" x 1.75" x 0.75"
' weight: 1 lb 7 oz
' number of ports: 2 - both ports are 1 Amp
' flashlight: yes
' pass through charging: NO (i.e. the battery CANNOT charge while being charged itself)
' cables: 1 charging cable

Since neither of the ports produced more than 1A this battery is best suited for Android devices, MP3 players, portable speakers etc. Just not devices that work best with 2A ports such as Apple devices.

This battery pack is provided by NewNew for testing and review. Getting a review product does not influence what I say, I run tests and report what I see purely based on a performance of the product.
