About 2.5 hours to fully recharge a Core from a standard 15A wall outlet. Recharging begins automatically when grid power returns — no action needed on your part.
CS Note: If a high load is being bypassed, charge time may be longer as to NOT trip the wall circuit breaker.
Also - if other loads are on the same circuit break but NOT plugged into backup, this may trip the breaker and backup will enter into battery discharge operation.
