1kWh in 1 Hour: Emergency Super Charge Explained

1kWh in 1 Hour: Emergency Super Charge Explained

Most power stations its size take half a day to refill. The Jackery Explorer 1000 v2 does it in about one hour. That speed has a name — Emergency Super Charge — and it changes how you use a backup battery. Here's what it is and when to use it.

The two charge speeds

On a standard wall outlet the 1000 v2 charges 0–100% in about 1.7 hours. Switch on Emergency Super Charge and it pulls more power to hit full in roughly 1 hour — ideal when a storm is coming and you want it topped off fast.

Why “an hour” actually matters

Backup power only helps if it's charged when you need it. A unit that takes 8–10 hours to refill is often half-empty at the worst moment. A one-hour refill means you can:

  • Top it off the moment an outage warning hits.
  • Recharge between uses on a camping trip during a quick stop.
  • Run it down powering tools or a cooler, then refill over a lunch break.

One owner reported their unit recharged in under 30 minutes after a trip left it at 60% — fast enough that it's always ready for the next use.

Other ways to recharge

Method Time to full
Emergency Super Charge (AC) ~1 hour
Standard wall (AC) ~1.7 hours
Solar, 2× SolarSaga 200W ~3.8 hours
Solar, 1× SolarSaga 200W ~7.5 hours
12V car outlet ~12 hours

Is fast charging hard on the battery?

No — the LiFePO₄ pack is rated for 4,000 charge cycles (10+ years), and ChargeShield 2.0 manages temperature and current to keep fast charging safe. Use Super Charge when you need speed; use standard charging day to day if you prefer.
