TSST TB100PA Portable Charger Review

To test the TB100PA's charging performance, we charged two phones and an iPad using the portable charger.

We charged each device on both USB ports included within the TB100PA (1.0A and 2.4A), as well as a third test using a mains AC adapter to allow a comparison between mains charging and the TB100PA.

For each of the three tests per device, we drained the device in question until the battery was completely flat, and then charged it for 30 minutes.

Using that information, we could then calculate the approximate time for a full charge (to 100%). This is not an exact figure, as charging is not a linear sequence.

That said, this methodology does allow a fair comparison between all the devices, as all started with batteries at 0%, and were charged for the same amount of time.
