Last time, we unboxed PowerWave, our new high-speed wireless charging series. This time, we’ll take a close look at PowerWave’s performance in comparison to other wireless chargers, as well as Apple’s conventional wired chargers. Let’s see how well PowerWave stacks up against the competition!
Mobile phone: iPhone X with iOS 11.2 or above, 0% power.
Wireless chargers: Anker PowerWave 7.5 Pad, Anker PowerWave 7.5 Stand, Belkin BOOST UP 7.5W Wireless Charger, and mophie Wireless Charge Pad.
Cable charger: Apple proprietary 5V 1A wall charger
Digital Multimeter: Tests input voltage of the wireless chargers.
True RMS Clamp Meter: Tests input current of the wireless chargers.
Power Z: Tests voltage and current at the same time—used to obtain data for the Apple wall charger.
We took 5 identical iPhone X devices and set them to charge in the same environment at room temperature, using one of each of the chargers above. Our goal was to find the full time required to charge iPhone X from 0 to 100%, and compare speed and progress incrementally during the charging cycle.
Below is a photo of the testing environment, with the current and voltage of the chargers visible on the meter displays.

We began the charging test at 3:25 PM, with iPhone X beginning at 0% battery life. At 3:55 PM, half an hour into charging, we observed the following:
There are few obvious differences this early in the charging cycle, though we see that the power output and input is higher for wireless chargers.
At 5:25 PM, after charging for 2 hours, the data are as follows:
We now begin to see some significant differences, with PowerWave pulling out ahead of the wireless charging pack, and keeping pace with Apple’s wall charger.
At 6:17 PM, after charging for 2 hours and 52 minutes:
At this point, we noticed that PowerWave’s current had dropped considerably, indicating that the charging cycle was almost over. Both PowerWave models, as well as Apple’s wall charger, had managed to charge iPhone X over 95%, with the other wireless chargers noticeably lagging behind as charging concluded.
This table shows the key charging data at each collection point:
When charging iPhone X, the PowerWave series keeps up with or surpasses the speed of Apple’s wall charger, while significantly outperforming the other wireless chargers in its class.
WaveBoost technology kicks the performance of wireless charging into high gear, letting it compete with conventional wall chargers for the first time ever.
