The Explorer 240 v2 in brief
Rated for 3,000 charge cycles to 80% capacity, the Explorer 240 v2 has the third-longest cycle life among the 13 stations under 300 Wh. It stores 256 Wh in LFP cells and weighs 7.94 lb, which works out to 32.2 Wh per pound. AC output is 300 W, with 600 W of surge allowed for short moments. A laptop runs 2.3 h to 6.2 h, a Starlink Mini 5.4 h to 8.7 h, and a Wi-Fi router 4.8 h to 25 h. A wall outlet refills it in 1.9 h. It carries UL 1778 certification, and Jackery backs it for 3 years, plus 2 more if you buy from Jackery. Anything drawing over 300 W is out of range, including an 875 W furnace blower and a 1,575 W space heater.
How long the Explorer 240 v2 runs things
Times use about 85% of the rated capacity, the part left after inverter and battery losses. The 256 Wh capacity and the 300 W output set the limit. A refrigerator running at 104 W lasts 2.4 h to 6.2 h, but its 1,305 W startup draw is beyond what this unit covers.
Work out your own mix of loads. A red bar means it draws more than the 300 W this station can supply.
How fast it refills
Solar time assumes panels reach 75% of their rating. Figure it for your state and panels.
Solar panels for the Explorer 240 v2
Solar goes in through its USB-C port, at 9 to 20 V and up to 100 W. Panels with barrel plugs need Jackery's DC8020-to-USB-C adapter, which settles the voltage with the station, so a plain panel voltage check does not apply. Confirm your panel on Jackery's list.
Who the Explorer 240 v2 suits
Pick it for a bag of small gear, such as a laptop, router and phones, where 7.94 lb matters more than output. Solar is limited to 100 W through its USB-C port, and panels need Jackery's DC8020-to-USB-C adapter, sold separately. Look elsewhere if solar is the main plan. The EcoFlow RIVER 2 holds 243 Wh, accepts 110 W of solar, recharges from the wall in 1 h and has a 5-year warranty. The BLUETTI EB3A offers 600 W of AC output at 268.8 Wh.

FAQ
Can the Jackery Explorer 240 v2 run a refrigerator?
A refrigerator drawing 104 W can run for 2.4 h to 6.2 h. Its 1,305 W startup draw is above what the 240 v2 covers, so it is a poor match for a compressor.
How long does the Explorer 240 v2 take to charge?
The wall outlet fills it in 1.9 h. Solar at the full 100 W input takes 3.4 h.
Does it switch over instantly during an outage?
Its switchover time is 20 ms. Jackery states that this product does not support 0ms switching.
What temperatures can it work in?
The rated range is 14 F to 113 F.
