When you’re off the grid, your gear matters. Whether you’re camping deep in the backcountry for the weekend or tackling a long overlanding adventure, dependable portable power can make or break your experience.
In 2025, one power solution that comes out swinging hard is the Sasquatch Outdoors 3000W Portable Power Station—a unit I saw first-hand at the recent California Overland Adventure and Power Sport Expo. With its rugged design, outstanding capacity, and tech-forward features, it’s built to meet the demands of modern explorers like you.
At the heart of this Sasquatch unit is a Lithium Iron Phosphate (LiFePO4) battery, which is known for safety, thermal stability, and longevity. This isn’t your average portable battery. It packs 2560Wh of capacity with a powerful 3000W inverter (5,000W peak), making it ideal for running everything from high-powered appliances to sensitive electronics. Thanks to its 4,000+ life cycles, you can rely on this station trip after trip, season after season.
Its performance in extreme conditions is another notable feature. The operating temperature range of -4°F to 113°F ensures reliable use in all kinds of environments, whether you’re winter camping in the mountains, chasing summer sunsets in the desert, or points in between.
One of the most impressive aspects of the Sasquatch 3000W is its wide array of output options that are tailored for real-world utility. It offers:

- Two DC outputs
- Four USB-A ports (two quick charge, two standard)
- Two 100W USB-C ports
- Anderson terminal and car port
- DC5521 ports for specialty equipment
Whether you’re charging a drone, powering a portable fridge, or setting up a full camp kitchen, this power station has the connections to support it all!
The Sasquatch 3000W Portable Power Station is as smart as it is tough. The LCD screen gives you all the details you need at a glance—battery percentage, remaining charge time, input/output wattage, temperature warnings, fan status, and more. You’ll never be in the dark about your power usage, even at night, thanks to its four screen brightness settings.
If you prefer to manage your gear from your phone, the Sasquatch has you covered. With Wi-Fi and Bluetooth connectivity and an available mobile app, you can monitor battery levels, track usage, and manage settings remotely. This level of control is especially helpful when your power station is stashed in a trailer or tucked under a gear bench.
Charging a big battery doesn’t have to take all day, either…
With 1800W max AC input, you can fully recharge the Sasquatch 3000W from the wall in just 90 minutes. But what makes this power station ideal for overlanders and campers is its dual solar panel compatibility—you can charge via PV up to 800W or combine wall and solar charging for a blazing 2560W max input. It also supports car charging while you drive, making it easy to keep topped up between stops.
Safety is non-negotiable when you’re overlanding, and Sasquatch Outdoors takes it seriously. The power station includes overload, short-circuit, temperature, overcurrent, and over-discharge protection, ensuring both you and your equipment are protected.
Meanwhile, its Emergency Backup Power function means you’ll always have juice when it matters most—ideal for keeping a heater or medical equipment running in the event of an outage. Plus, it automatically shuts down after one hour of inactivity on the AC ports, helping to conserve energy when not in use. Not bad, right?!
Weighing in at 75 lbs, the Sasquatch 3000W is undeniably a beast—but that’s the tradeoff for serious capacity and performance. Its compact design (21″ x 12″ x 13.5″) still fits easily into most overlanding rigs, camper trailers, or truck beds, and the durable build means it’s ready to tackle whatever terrain you travel. Plus, the integrated handle and wheels make moving this portable power station around much easier.
Bottom line? If you’re looking for a fantastic portable power system for your outdoor adventures in 2025, the Sasquatch Outdoors 3000W Portable Power Station is a prime option. With high-end performance, unmatched versatility, and the durability to go wherever you do, it’s more than just a battery—it’s the power lifeline for your adventures!

Best Portable Batteries of 2025: EcoFlow Delta 2 Max
When you’re off the grid—whether it’s camping, overlanding, or riding out a power outage—having a dependable power source is critical. After a full year of real-world use, I can confidently say that the EcoFlow Delta 2 Max stands out as one of the best portable power stations of 2025. It’s more than just numbers on a spec sheet—it’s a dependable workhorse that’s become a core part of my off-grid setup.
At the heart of the Delta 2 Max is a 2048Wh Lithium Iron Phosphate (LFP) battery that can be expanded up to 6144Wh. That’s enough capacity to power everything from a portable fridge and Starlink dish to laptops, lights, and a coffee maker.
It features six 2400W AC outlets (with a 4800W surge), two fast-charging USB-C ports, four USB-A ports, and a 12V car port. Whether you’re running sensitive electronics or high-draw appliances, this power station handles it all.
Even more impressive is its X-Stream charging technology—you can go from 0 to 80% in under 45 minutes with combined solar and AC input. Purely on AC, you’re still looking at just over an hour. And with up to 1000W of solar input, it recharges fast even in the field.
At 50 lbs, the Delta 2 Max isn’t featherlight, but it’s manageable thanks to its ergonomic handles and compact form factor (19.6 x 9.5 x 12 inches). Its rugged build—featuring a solid metal chassis and reinforced plastic edges—makes it ideal for camping and off-road use. I’ve tossed it in the back of my rig countless times without issue.
The interface is intuitive, with a bright display that shows input/output stats, battery percentage, and active ports at a glance. It’s clear EcoFlow put serious thought into user experience.
What sets the Delta 2 Max apart is how seamlessly it integrates into your daily routine. The EcoFlow app offers Bluetooth and Wi-Fi control, so you can monitor usage, control outlets, and adjust settings from your phone. It even lets you set charge thresholds to extend battery life.
The Delta 2 Max also includes UPS functionality, meaning it automatically kicks in if your home loses power—perfect for keeping essential electronics like routers and modems online without interruption.
Are there downsides? Sure. It’s not cheap, especially if you add solar panels or expansion batteries. And I’ve had minor glitches like random USB shutdowns and a finicky 12V port. But these were easily resolved and don’t outweigh the overall reliability.
After 12 months of use, the EcoFlow Delta 2 Max has proven itself as a reliable, powerful, and flexible solution for off-grid energy. Whether you’re a weekend camper, full-time van lifer, or just prepping for the unexpected, this unit delivers serious performance in a compact package. For me, it’s not just a battery—it’s peace of mind.

Whether you’re on a snowy ridgeline or deep in the desert, this power station is built to keep going.
What really makes the FLEX 1500 Tactical a standout for year-round use is its integrated battery heater, which allows it to function in temperatures as low as -22°F. This is a critical feature for winter campers, overlanders, and emergency responders who operate in sub-zero conditions. No more worrying about a dead battery when the mercury drops—this power station is built to thrive in the cold.
Security is also a key feature. In a time where electromagnetic pulse (EMP) protection is a growing concern, the FLEX 1500 Tactical steps up with enhanced EMP shielding, developed in collaboration with EMP SHIELD Inc. This gives users an extra layer of confidence that their gear will stay functional even in the face of rare but potentially devastating threats.
Despite its rugged design and robust performance, the FLEX 1500 Tactical remains portable. Weighing just 41 pounds and measuring 14″ x 8″ x 8.9″, it’s compact enough to fit in your vehicle or gear trailer without taking up unnecessary space.

The 1800W model uses a LiFePO4 (lithium iron phosphate) battery, which is known for its safety, stability, and long life. With a lifespan of over 3,000 cycles, this power station is ready to handle years of use in rugged environments. It holds a capacity of 1229Wh (operating at 51.2V and 24Ah), making it efficient and long-lasting even when drawing substantial power.
The front-mounted LCD screen keeps you informed with real-time data on battery percentage, remaining charge time, power input/output, and system temperatures.

Best Portable Batteries of 2025: Lion Energy Safari Portable Power Station Bundle
A while back, I tested the Lion Energy Safari Portable Power Station Bundle that includes six 24-volt, 100-watt solar panels. I also tested the Lion Energy Safari XP Expansion Pack, giving the system a serious boost in energy storage capability. I’ll say this right up front—it’s been extremely impressive.
Not only does this bundle provide a ton of power, but it’s also easy to use and highly portable. When you’re relying on a power station in the middle of nowhere, that kind of usability is a must.
The Lion Energy Safari is a heavy hitter in the portable power game. It weighs 57.3 lbs and measures 20″ x 13.3″ x 13.3″, so it’s not exactly compact—but with the amount of power you get, the tradeoff in size is well worth it.
You get four Pure Sine Wave AC outlets for clean, stable power, plus two USB-A ports (5V @ 3A each) and two USB-C ports (20V @ 3A, 60W max), giving you plenty of flexibility for charging everything from smartphones to laptops.
For 12V needs, it includes both a 12V output at 15A and a 12V Anderson-compatible port at 25A—perfect for powering a variety of gear when you’re off-grid or in an emergency.
The heart of the system is a 1612Wh LifePO4 battery, offering 3000W of continuous output and up to 6000W surge. It’s built to handle heavy-duty tasks while delivering reliable power over the long haul.
This unit also features 3500+ life cycles, meaning it’s built for years of use whether you’re camping, working outdoors, or preparing for emergencies. Charging options are flexible, too, with AC, DC, and solar capabilities. The AC input handles 102–130V at 45–65Hz, while solar and DC charging max out at 600W using MPPT tech.
And if you’re like me and don’t want to worry about frequent top-offs, you’ll appreciate the one-year charge retention and quick recharge times—just 2 hours and 35 minutes under ideal conditions.
The 24-volt, 100-watt solar panels are the perfect match for the Safari. Not only are they efficient, but they’re also built tough and designed with sustainability in mind.
The eco-conscious design produces zero emissions, helping you reduce your carbon footprint without sacrificing performance. Each panel is housed in a double-walled, anti-corrosive aluminum frame, making them rugged enough to handle unpredictable weather and rough outdoor conditions.
With each panel delivering 100 watts, and my system running six of them, I have plenty of solar capacity to keep my devices powered and my power station charged. This flexibility is great—you can run just one or link up to six panels depending on your energy needs.
The Safari XP Expansion Pack takes everything to the next level. When you need more power than the Safari alone can provide, the XP delivers.
With 3,000W of output and a 4,300Wh LifePO4 battery, it multiplies your energy storage by three. Connecting it is as simple as plugging it into the back of the Safari. No complicated wiring, no tech headaches—just more power, instantly.
It shares many of the Safari’s features, like maintenance-free operation and one-year charge retention, and it’s just as easy to transport and set up.
I’ve used this expanded system to power everything from Starlink internet to laptops, phones, camera batteries, and even lighting. But it’s capable of much more—think power tools, mini-fridges, CPAP machines, blenders, drones, and even TVs.
Whether you’re at a campsite, tackling a DIY project, or riding out a power outage, the Safari+XP setup is ready to go!
