Recommended AC Adapters
For a 20,000 mAh battery pack like the PowerPack 20000, it is crucial that the battery gets electricity as fast as possible during recharge, so that it can be ready for the next use in no time. A more powerful charger with a higher rated wattage (18W+) is strongly recommended. The PowerPack 20000 is designed to recharge via USB PD or Quick Charge fast-charging power adapters as well as via conventional power plug. Here are some suggested power adapters for recharging the PowerPack:
- MacBook (2015 or later), MacBook Pro (2016 or later) stock Apple USB-C power adapter (29W, 61W, or 87W)
- Google Pixelbook USB-C power adapter (45W)
