The mophie Powerstation USB-C XXL is now sold through the Apple Store so let's see how it charges the 13" MacBook Pro (2017) using USB Power Delivery 2.0 technology.

With the 13" MacBook Pro (2017)'s battery fully discharged, we connected the Mac to the mophie Powerstation USB-C XXL which itself was about 20% charged. In this dead battery situation, the 13" MacBook Pro (2017) was not able to pull any current from the mophie Powerstation USB-C XXL and thus not able to properly charge. Click here to download the trace captured by the GRL-A1 power analyzer to see more details on how the mophie  Powerstation USB-C XXL at 20% battery, charged the 13" MacBook Pro (2017) at 0% battery charge.

After we charged the 13" MacBook Pro (2017) with the Apple 61W USB-C Power Adapter to 45%, we then reconnected the mophie Powerstation USB-C XXL at the same 20% charge level on the charger. This time we could see that the 13" MacBook Pro (2017) pulled up to 30 watts from the mophie  Powerstation USB-C XXL. While 30 watts provides a slower charging speed compared to the 61 watts that you can get from Apple's 61W AC wall charger, the mophie Powerstation USB-C XXL is still useful when you are on the road and need to keep your battery charge from going to zero. Click here to download the trace captured by the GRL-A1 power analyzer to see more details on how the mophie Powerstation USB-C XXL at 20% battery, charges the 13" MacBook Pro (2017) at 0% battery charge.
