Jackery Explorer 240 v2 Review UK
The Jackery Explorer 240 v2 is a pocket-sized portable power station built for the sort of lightweight trips where weight and pack size matter more than raw output. At 256Wh and just 3.6 kg, it slots neatly into a daypack or glovebox — and with LiFePO4 chemistry rated to 3,000+ cycles, it should still be holding charge long after most camping gear has worn out.
This isn’t about powering a full campsite. It’s about keeping phones, cameras, a laptop, LED lights and a small 12 V coolbox running without hunting for a mains socket. If that’s your use case, the 240 v2 delivers exactly what it promises — reliably and quietly.

What the 240 v2 does well
The standout feature is charge speed. Jackery’s fast-charge system fills the battery from flat in around an hour via mains — genuinely useful when you’re packing the night before a trip and realise it’s sitting at 20%. The 100 W USB-C port is bidirectional, so it doubles as a laptop charger without needing the AC inverter, which saves energy and runs silently.
LiFePO4 chemistry is the real upgrade over the original Explorer 240. The older NMC cells were rated at around 500 cycles; the v2’s LFP cells should manage 3,000+ to 80% capacity. For something that might sit in a car boot between trips, that longevity matters.
At 3.6 kg, it’s light enough to carry one-handed. The fold-down handle is comfortable and the footprint is small enough to slip alongside a cool bag in a boot.
Honest limitations
300 W continuous output means no kettles, no hair dryers, no heaters — anything with a heating element is off the table. It’s a charging and lighting station, not a campsite generator.
256 Wh goes quickly if you’re running an AC device. A 50 W laptop would drain it in around four hours through the inverter. Switch to USB-C direct and you’ll stretch that considerably, but it’s still a compact unit with compact capacity.
There’s no expansion battery port. What you see is what you get — if you need more capacity later, you’re buying a second unit or stepping up to a larger model.
Who should consider it
Weekend campers who need phone/laptop/light power without the weight of a larger unit.
Festival-goers — small enough to carry, enough capacity for a weekend of device charging.
Day-trip photographers or drone pilots needing a field charging station.
Van lifers who already have a main system and want a grab-and-go backup for overnight stops.
Anyone wanting a bedside UPS for a router and phone charger during power cuts.
Who should look elsewhere
If you need to run a fridge, CPAP machine, or any appliance above 300 W — step up to the EcoFlow RIVER 2 Pro (768 Wh, 800 W) or similar.
If you want expandable capacity for multi-day trips — the 240 v2 is a sealed, single-battery unit.
If you need a home backup solution — 256 Wh isn’t enough for meaningful power-cut cover.
