How we test

Determining whether a power bank satisfies an organization’s guarantee involves more than basically associating it to a telephone and charging. Testing battery packs is done over weeks, not days, and requires additional hardware to guarantee the batteries fill in as expected.


1. After accepting every battery pack, it’s completely energized, utilizing marker lights as a way to follow charge level.



As we utilize the DROK load analyzer to deplete the pack of power, we can test against a battery’s expressed most extreme current, and check that legitimate closure components are set up should something turn out badly during a charging meeting, (for example, a gadget drawing over the greatest amps).


By utilizing the AVHzY USB Power Meter, we can screen volts and amps, all out power throughput, and aggregate sum of time to drain a battery from full to discharge. The meter can make an Excel bookkeeping page of the whole interaction for future reference. 


3. Then, we re-energized the battery, this time utilizing the AVHzY to follow it and diagram the measure of time it takes to arrive at full charge. 


The AVHzY meter addresses a deficiency we had with our past technique with the PortaPow. Beforehand we needed to utilize a GoPro camera to follow every battery through its charge cycle, as the PortaPow screen would keep on gathering information after the battery was completely energized (stream charging is typical, and sadly meddles with our testing). 


If a battery was fit for charging through USB-C, we utilize that rather than Micro-USB.


4. The AVHzY additionally has an element inherent that checks a charging port for the entirety of its upheld charging principles. We can run that test and get a moment readout to affirm uphold for QC 3.0, for instance, without expecting to have viable telephones or gadgets on hand. 

Power source and cables
All of our tests were led utilizing a similar divider connector and, whenever the situation allows, USB-C or Micro-USB link. This was done to kill any disparities with divider connectors and link throughput.

What to search for in a convenient power bank

Without extravagant testing gear, you never really know whether you’re getting what you paid for with a battery pack. Sellers, particularly in Amazon postings, as to toss around a great deal of terms and certifications.

  • Don’t put 100% trust in an organization’s cases of a pack having the option to charge, say, a Galaxy S8 or iPhone X multiple times over. Battery limit and effectiveness differs dependent on various variables. Understand this Macworld report on USB-C packs to study batteries and capacity.
