Differences Jackery Explorer 240 vs Jackery Explorer 300 Plus
Below is a summary of the specifications:
Battery Capacity, Expandability, and Battery Lifespan
The Anker 521 PowerHouse offers a slight edge in raw battery capacity at 256Wh, compared to the 240Wh capacity of the Jackery Explorer 240. Although the difference in capacity is marginal, Anker’s true strength lies in its LiFePO₄ (LFP) battery chemistry, which drastically extends its usable life.
The Anker 521 is rated for over 3,000 charge cycles to 80% capacity, giving it a lifespan that could stretch beyond 8–10 years with regular use. In contrast, the Jackery Explorer 240 uses NMC cells, which provide only 500 cycles to 80%. This means frequent users may experience battery degradation in less than two years with Jackery, while the Anker unit will maintain a high performance level for many times longer.
Neither unit supports battery expansion, so buyers must select based on the included internal capacity and long-term performance expectations.
Winner: Anker 521 PowerHouse
Superior battery chemistry and significantly longer cycle life make the Anker 521 a much more durable and future-proof power station.
Power Output and Appliance Compatibility
Both the Jackery Explorer 240 and the Anker 521 deliver 200W of continuous AC output, with the Jackery offering 400W surge capacity, while the Anker provides a slightly higher 450W surge. These specifications are appropriate for powering low-wattage devices like phones, cameras, routers, projectors, small fans, LED lights, and some mini-fridges with inverter technology.
The Anker 521 includes two AC outlets, allowing for more flexible device usage, while the Jackery Explorer 240 only features one AC outlet. This limitation can be a concern if you need to power more than one AC device at a time.
Both units include pure sine wave inverters, ensuring safe use with sensitive electronics. However, the Anker 521 also offers surge support with slightly better stability, reducing the likelihood of accidental shutdowns under fluctuating loads.
Winner: Anker 521 PowerHouse
More AC ports and higher surge capacity give it a meaningful advantage in versatility and appliance support.
Charging Speed and Solar Input
When recharging through AC power, the Jackery Explorer 240 accepts only 42W input, taking approximately 5.5 hours to fully recharge. By comparison, the Anker 521 PowerHouse charges via 65W AC input, reducing the full charge time to around 4.5 hours, making it more convenient for users who need shorter turnaround times.
Both models support solar charging with MPPT controllers, offering a maximum solar input of 65W and accepting voltages between 11–28V. Charging times under direct sunlight typically range from 5 to 8 hours with compatible panels.
For car charging, both support 12V input, but not 24V systems. In mobile environments or RV setups, recharge times via DC will depend on driving duration and battery condition.
Winner: Anker 521 PowerHouse
Faster wall charging and equivalent solar performance make the Anker 521 more time-efficient and practical for mobile users.
Portability and Design
The Jackery Explorer 240 weighs 3.1 kg, making it slightly lighter than the Anker 521, which comes in at 3.7 kg. This weight difference is negligible for most users, but for ultralight campers or travelers counting grams, the Jackery may be the better option.
Design-wise, the Anker 521 adopts a vertical form factor, providing a compact footprint and a top-mounted handle for stable carrying. It also includes rubber feet for added stability on slick surfaces. The unit has a clean interface with an easy-to-read display.
The Jackery Explorer 240 has a horizontal layout, classic orange-and-grey aesthetics, and a slightly slimmer profile, which can fit neatly into narrower storage compartments. However, it lacks the polished visual appeal and layout convenience of the Anker unit.
Winner: Jackery Explorer 240
Slightly lighter and more compact in width, it holds a small advantage for pure portability, though Anker is more ergonomic in hand.
Smart Features and User Interface
Neither the Jackery Explorer 240 nor the Anker 521 includes smart app connectivity, Wi-Fi, or Bluetooth control. All operations are manual, via physical buttons and integrated LCD displays that show battery percentage, input/output wattage, and port status.
The Anker display is more modern and visually refined, with a clear layout that includes estimated remaining runtime and charging time. The Jackery display is functional but more basic in comparison, lacking advanced feedback or visual sophistication.
Winner: Anker 521 PowerHouse
A better-designed display and clearer readouts give it an edge in real-time usability, despite no app features in either model.
Ports and Output Variety
The Anker 521 PowerHouse includes two AC outlets, two USB-A ports, one USB-C port at 60W, and a 12V car port. The addition of USB-C PD enables fast charging for laptops, tablets, drones, and other USB-C powered gear without relying on adapters.
The Jackery Explorer 240 lacks USB-C entirely. It includes one AC outlet, two USB-A ports, and a 12V car port, limiting its compatibility with newer electronics and making it dependent on external power bricks for devices like MacBooks or USB-C charging cameras.
Winner: Anker 521 PowerHouse
With USB-C and dual AC outlets, it clearly offers more modern and useful output options for today’s electronics.
