How fast can these recharge from a wall outlet?

Fast AC charging is a key differentiator. Several units here advertise roughly one-hour or sub-one-hour recharges from empty, with the Anker SOLIX C1000 Gen 2 claiming a full charge in about 49 minutes and the DJI Power 1000 V2 claiming 0-80% in around 37 minutes. Real-world times vary with charge settings, and faster charging can add fan noise.
