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 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:

“One other neat feature: USB battery power is clean. If your audio gear buzzes when you connect it together and power it from a regular USB charger, try using this battery pack instead. I find it eliminates buzz, while still keeping everything charged.” —  This is the handiest travel battery you can buy [Review]
