Ahhh the Jackery “Generator.” Battery packs are NOT GENERATORS. They may advertise them as off grid power supplies, or falsely as battery generators, BUT generators create electricity and battery packs do not. A generator with gas or diesel will continue to create electricity as long as there is gas or diesel in it. The jackery or whatever other brand has a finite amount of stored power, usually enough to power a few lights for a few hours, but a 100ah battery pack only has enough juice to run a dryer or toaster or refrigerator for 1hr. Once the power is gone it needs electricity to be replenished
