| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 256 Wh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP (upgraded from NCM) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | 3,000 life cycles. The capacity left at the end is not stated |
| ExpansionExtra battery units that add storage to the same system. | Not stated |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | Jackery says appliances should not exceed 300 W. 1 AC outlet |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | Not stated |
| USB-APorts for phones, tablets and small devices. | 1 port. The power is not stated |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 1 USB-C output port plus a USB-C input/output port with 100 W PD two-way fast charging |

| Time to charge from the mainsHow long a full charge takes from a wall socket. | 2 hours from the wall; 1 hour (0 to 100%) in emergency charging mode, activated in the app |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | A 100 W panel charges it in about 3.3 hours. The maximum input is not stated |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | About 5 hours. The charging cable is sold separately |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | 20 ms or less (IEC 62040 certified). Jackery says it supports some desktop computers and CPAP machines, and a 15 W router for up to 16 hours |

We do not show prices, because they change often and differ between sellers.

Common questions about Jackery Explorer 240 v2
What can the Explorer 240 v2 run?

Is the Explorer 240 v2 still sold?
Jackery's UK page marks it as sold out and discontinued. Check Jackery's current range for a successor.
Is the Explorer 240 v2 the same as a home battery?
