Works great in a back pocket due to its shape and outputs 3 amps through the USBC port. 10000 mAh and my session took it from 4 dots to 2 dots. Quest Pro was full-ish (the battery indicator appeared 100% in the Quest when I quit, I didn't drill down to the exact percentage, but it still charged for 15 minutes when I put it back on the dock).
