To test the Luxa 2 TX-P1 powerbank, we decided to put wireless charging against the more traditional wired method. We measured how long it took for a Samsung Galaxy SIII to charge from 0-100% from the wall, from the power bank running off of its in-built battery and then once again with the power bank plugged straight in to the wall without using its in-built battery.
As you can see, wireless charging from the power bank certainly takes its time, coming in at 330 minutes, which is a hefty two hours longer than charging straight from the wall.
Having the power bank plugged in did help speed things up considerably, however, it did cause both the bank and the phone to heat up, so we wouldn't recommend leaving it plugged in all of the time.
We also ran a test on how long it takes to charge the 5000mAh battery inside of the TX-P1:
It takes just over seven hours to charge the 5000mAh battery inside the TX-P1, which wouldn't be so bad if it could charge the Samsung Galaxy SIII multiple times on a single charge. Unfortunately, we only managed to get one charge out of the power bank before having to plug it in again, meaning you will have to charge the bank itself almost as often as you would your phone.
