What Jackery Publishes for the Explorer 240 v2
- Capacity: 256Wh (20Ah at 12.8V DC), per the user manual
- Chemistry and life: LiFePO4, rated at 3000 cycles to 80%+ capacity
- AC output: one outlet, 300W rated, 600W surge peak, 120V 60Hz
- USB-C: one 100W max in/out port (5V3A, 9V3A, 12V3A, 15V3A, 20V5A) and one 15W output
- USB-A: one 15W port; the 15W USB-C output and the USB-A port share a 24W combined limit
- DC: 12V 10A car port
- AC charging: 100-120V, 10A max; about 2 hours for a full charge per Jackery’s product page
- Solar and car charging: 100W max through the USB-C in/out port with a separately sold DC8020-to-USB-C adapter; a 12V car charger takes about 5 hours (page claim)
- Weight and size: about 7.94 lb (3.6 kg) per the manual, 9.1 x 6.0 x 6.6 in
- Operating range: discharge -10 to 45C (14-113F), charge 0 to 45C (32-113F)
- Warranty: 3 years standard plus 2 years extended with registration on official-site purchases
Two small conflicts in Jackery’s own material are worth knowing. The manual gives the weight as about 7.94 lb, while marketing text on the US product page says 7.7 lbs. The manual gives the discharge range as -10 to 45C, while a notice on the product page says -10 to 40C. We use the manual figures above and treat the page figures as rounder marketing numbers.
What LFP Changes on Paper
LFP (lithium iron phosphate) cells trade some energy density for longer cycle life and better thermal stability than the NMC cells used in many older power stations. Jackery rates this pack at 3000 cycles to 80%+ capacity. If that claim holds, a weekly full cycle would take many years to reach it, so for a unit that mostly sits in a closet or a vehicle the calendar age of the cells is likely to matter before the cycle count does. We have no way to confirm the cycle figure; it is a manufacturer rating.
Weight is the other half of the trade. At 256Wh and 3.6 kg, the pack works out to about 71Wh per kilogram of whole unit, which includes the case, inverter and electronics. That is a simple division of two published numbers, not a measured energy density.
Runtime Estimates From the Numbers
Jackery publishes no runtime table we could verify, so these are our own estimates. They assume about 85% of the 256Wh is delivered through the AC inverter, which gives roughly 218Wh of usable energy. The real figure depends on inverter efficiency, temperature and load.
- A 30W load, such as a small fan, would run roughly 7 hours (218 / 30).
- A 50W load, such as a small TV or a string of lights plus a charger, would run roughly 4 hours (218 / 50).
- A 100W laptop-class load through the 100W USB-C port avoids the inverter, so the ceiling is about 2.5 hours (256 / 100) before losses.
- At the full 300W rating the unit would be empty in well under an hour.
The takeaway is that 256Wh is a small tank. It suits phones, tablets, a laptop and LED lighting for short periods. Check your device’s wattage label and divide.
Ports and What They Imply
One AC outlet is the clearest limit. A second AC device needs a power strip, and the combined draw must stay under 300W. On the DC side, the 100W USB-C in/out port is the most useful connector: it can charge a laptop directly, and it is also the solar input. The 15W USB-C and 15W USB-A outputs are phone-speed ports, and the 24W combined limit means using both at once will not give each its full rated power. The 12V car port covers 12V accessories.
Charging and Solar
Jackery lists a full AC recharge in about 2 hours, with an app-activated emergency mode that it says cuts that to about 1 hour. Solar goes through the same 100W USB-C port, so a larger panel will not charge it faster than 100W. Jackery’s page claims about 11 hours with a 40W panel and about 3.3 hours with a 100W panel. The adapter is sold separately, and the unit accepts a 12V car charger only, not 24V, so it will not charge from a 24V truck system.
Pass-Through, UPS and Cold Weather
Jackery’s manual describes a UPS function that switches to battery within 20ms and states that it does not support 0ms switching; the product page cites UL1778. Bypass AC output is limited to 300W. For a modem and router that is fine. It is not a good fit for a desktop PC or a server. Charging is allowed only from 0 to 45C, so a unit that has been sitting in a freezing car should be warmed before plugging in. Jackery’s manual lists a storage range of -10 to 25C for storage up to 6 months.
Who It Suits and Who Should Skip It
On paper it suits campers who need to top up phones, a tablet and a laptop, people who want a small blackout kit for a router and lights, and anyone who values low weight over capacity. We would pick it where 3.6 kg matters and where the loads stay well under 300W.
Skip it if you need to run a microwave, a coffee maker, a space heater or power tools, if you want to expand capacity later (Jackery publishes no expansion option), or if you want a 24V vehicle charging input. For bigger loads, look at a larger station.
Frequently Asked Questions
Is the Jackery Explorer 240 v2 an LFP battery?
Yes. Jackery’s manual lists LiFePO4 chemistry and a rating of 3000 cycles to 80%+ capacity. That is a manufacturer claim, not a measured result.
How much power can it output?
Jackery rates the single AC outlet at 300W continuous with a 600W surge peak at 120V. Anything that needs more than that, such as most space heaters, kettles or hair dryers, is outside its design. Jackery publishes no boost mode and no expansion battery support.
Can it run as a UPS?
Jackery’s manual says it switches to battery within 20ms and does not support 0ms switching, so it is suited to routers, modems and similar gear rather than servers or workstations that cannot tolerate any gap.
How fast does it charge?
Jackery lists a full AC charge in about 2 hours, or about 1 hour in an app-activated emergency mode. On solar, the page claims 11 hours with a 40W panel and 3.3 hours with a 100W panel, through a USB-C port and a separately sold adapter.
Is the Explorer 240 v2 still sold?
It was still listed on jackery.com on 2026-10-06, and Jackery lists no discontinuation or replacement notice. Stock status was not verified.
Bottom Line
The Explorer 240 v2 is a light, small LFP power station with a 300W inverter, a useful 100W USB-C port and a five-year total warranty if bought from Jackery and registered. Its limits are equally clear: 256Wh of capacity, one AC outlet, no expansion and a UPS switch time of 20ms. Match it to loads under 300W and short runtimes and the specifications make sense; for anything larger, a bigger unit is the safer choice.
