Who should not buy the Jackery Explorer 240 v2?

Skip the Jackery Explorer 240 v2 if any of these describe you; each comes from its published specs.

  • You rely on solar. Even at its full 100 W solar input it needs about 2.6 hours of strong sun to refill, slower than most models its size. The EcoFlow RIVER 3 Plus needs about 1.3 hours at its limit.
  • You may want more battery later. The Jackery Explorer 240 v2 isn't listed as expandable. The EcoFlow RIVER 3 Plus (286 Wh) accepts extra batteries.
  • You want to run a kettle, microwave or space heater. Its 300 W inverter is below the 1,000 W or more our cited figures give for each of them. The BLUETTI Pioneer Na delivers 1,500 W.

How long does the Jackery Explorer 240 v2 last at different loads?

About 218 Wh reaches the AC outlets, so a steady 100 W load runs for about 2.2 h and a load at its full 300 W rating for about 44 minutes.

Steady AC loadRuntime from full
25 W8.7 h
50 W4.4 h
100 W2.2 h
200 W1.1 h
300 W44 min

What does the Jackery Explorer 240 v2 cost per kWh over its rated life?

About $0.24 per kWh of storage at list price, if you use all 4,000 rated cycles. The median for under 500 Wh models is $0.31 per kWh, so the Jackery Explorer 240 v2 is cheaper over its rated life.

Rated life energy = 256 Wh × 4,000 cycles ≈ 1,024 kWh. List price $249 ÷ 1,024 kWh ≈ $0.24.

How many hours of sun does the Jackery Explorer 240 v2 need to refill?

With panels delivering 75% of their rating (our calculator's default), the Jackery Explorer 240 v2 needs the hours of strong sun below. Its 100 W solar limit caps the charge rate, so panels beyond about 133 W add nothing in strong sun.
