Camping Battery and Portable Power Stations
Camping Battery & Portable Power Stations for Overlanding & Off Road
A camping battery is a portable power station, lithium battery pack, or solar generator that keeps your fridge running, lights on, devices charged, and CPAP working when you're camping, overlanding, or driving off road for days without grid power. We carry camping batteries and portable power stations from EcoFlow and National Luna, plus a bifacial solar panel that turns any unit into an indefinite-runtime off grid power system. Prices start at $299 for the EcoFlow RIVER 3 Plus and run up to $3,699 for the EcoFlow DELTA Pro 3 flagship. Every unit on this page uses lithium iron phosphate (LiFePO4) chemistry, ships with a real warranty, and is sized for genuine camping and overlanding use, not just emergency home backup. Call us at 844-200-3979 to talk through capacity sizing for your fridge, lights, and other camp loads.

Why You Need a Camping Battery on Off-Grid Trips
A camping battery solves a specific problem that grows more painful the longer you camp: keeping electrical loads running without idling your truck. Modern overland setups have real power requirements (a 12v fridge draws 1-2 amp-hours per hour, LED lighting adds another 1-3 amp-hours, charging phones and cameras adds 0.5-1 amp-hour daily, a CPAP machine adds 5-8 amp-hours per night). Running these off your starter battery for more than a day risks leaving you stranded with a dead battery and a 40-mile walk. This is exactly the problem portable batteries and dedicated camping batteries are designed to solve.
A dedicated portable power station or camping battery handles all that load without touching your vehicle's electrical system. The RIVER 3 Plus handles a weekend; the RIVER 2 Pro handles 2-3 days; the RIVER 3 Max Plus with extra battery handles 3-4 days; the DELTA Pro 3 handles a week or more. Add a portable solar panel like the 220W bifacial and runtime becomes indefinite as long as you're getting decent sun. The right camping battery for your build is whichever capacity matches your real loads with 25% headroom on top.
Why LiFePO4 chemistry matters: Every EcoFlow unit on this page uses lithium iron phosphate (LiFePO4) batteries instead of the older lithium-ion or lead-acid chemistries. LiFePO4 cells survive 3,000-6,500+ charge cycles (vs 500-1,000 for older lithium-ion), tolerate higher temperatures without thermal runaway, hold capacity better in cold weather, and don't lose significant capacity over the first few years of ownership. The trade-off is slightly higher up-front cost and slightly heavier weight, but for off road and camping use the longer lifespan is worth it.
How to Size Your Camping Battery
Sizing a portable power station for camping comes down to one calculation: total watt-hours per day of all your loads multiplied by your trip length in days.
Typical camp loads (daily watt-hour consumption):
12v portable fridge: 25-50 Wh per day depending on ambient temperature and how often you open it. ~35 Wh average for a 50-quart fridge in moderate conditions.
LED lighting: 5-15 Wh per day for typical camp lighting (string lights, headlamps charged via USB, area lights).
Phone and camera charging: 30-50 Wh per day for 2-3 phones and a camera body.
Laptop work: 50-80 Wh per day for 2-3 hours of laptop use.
CPAP machine: 50-100 Wh per night without humidifier; 100-200 Wh per night with humidifier.
Sum your daily loads, multiply by trip length, then add 25% headroom for inefficiency and unexpected loads. A typical couple's overland trip with fridge, lights, two phones, and a camera runs about 100-150 Wh per day. A 768Wh RIVER 2 Pro handles 5+ days of that load profile without recharging; the 4,096Wh DELTA Pro 3 handles 25+ days.
Portable Solar Generators: Pairing a Power Station With Solar
A portable solar generator is just the combination of a portable power station and a solar panel. The panel captures sunlight, sends DC power to the station, the station stores it in the lithium battery, and you draw it out through AC outlets, USB ports, or 12v connections as needed. This is the standard off grid power configuration for serious overlanders and expedition users.
The EcoFlow 220W bifacial solar panel on this page pairs with any RIVER or DELTA series unit. In full sun (4-6 productive hours per day depending on latitude and season), it generates roughly 800-1,200 Wh per day. That's enough to recharge a RIVER 2 Pro from empty to full in one day, or to keep a DELTA Pro 3 topped up indefinitely under normal overland power loads.
For owners wanting maximum solar capacity, the DELTA Pro 3 accepts up to 2600W solar input simultaneously, which means you can run three or four bifacial panels in parallel for serious off-grid living scenarios. Most overlanders find one or two panels is enough for typical use, with the second panel adding redundancy more than capacity.
EcoFlow vs National Luna: Which Should You Pick?
EcoFlow is the modern consumer power station leader. The RIVER and DELTA series win on capacity-per-dollar, fast charging, USB-C and AC output flexibility, app integration, and the modular expandable battery system in the DELTA series. The downside is that EcoFlow units are built for consumer use and home backup as much as overlanding, so they're less rugged than purpose-built expedition gear. For 80% of overland and camping users, an EcoFlow is the right call.
National Luna builds the National Luna Portable Power Pack specifically for off road and expedition use. The case takes vibration that consumer units don't tolerate well, the battery management is optimized for the 12v overland load profile (especially National Luna fridge integration), and the South African expedition design heritage shows in every detail. Choose National Luna if you're running National Luna fridges, doing genuinely rough overland expeditions where vibration and shock matter, or simply prefer the overlanding-specific build philosophy.
Frequently Asked Questions
What size camping battery do I need for a portable fridge?
A 12v portable fridge typically draws 25-50 watt-hours per day depending on ambient temperature, size, and how often you open it. For a 1-2 night trip with just the fridge running, the EcoFlow RIVER 3 Plus (286Wh) is sufficient. For 2-3 days, step up to the RIVER 2 Pro (768Wh). For 3-4 days, the RIVER 3 Max Plus + Extra Battery (600Wh + expansion). For a week or more, the DELTA Pro 3 (4096Wh). Add 25% buffer if you also need to charge devices, run lights, or use a CPAP.
Can I use these portable power stations at home for backup?
Yes, every EcoFlow unit on this page doubles as home emergency backup. The DELTA Pro 3 in particular is built for both off road camping use and home backup, with the modular battery expansion system letting you scale capacity for whole-home backup during power outages. The RIVER series is sized more for camping but still handles refrigerator, lights, and critical electronics during shorter outages.
How long does it take to charge a portable power station from solar?
Depends on the panel and the station. The EcoFlow 220W bifacial panel generates roughly 800-1,200 Wh per day in full sun (4-6 productive solar hours). That's enough to fully charge a RIVER 2 Pro (768Wh) in one solar day, or to keep a DELTA Pro 3 topped up against normal overland loads. For faster charging, run multiple panels in parallel; the DELTA Pro 3 accepts up to 2600W solar input.
Are portable power stations safe to use inside a tent or RV?
Yes. Unlike gas generators, portable power stations produce zero emissions, zero noise, and no combustion. They're safe to run inside tents, rooftop tents, RVs, and any enclosed space. The LiFePO4 battery chemistry used in every unit on this page is also significantly safer than older lithium-ion chemistries, with much higher thermal stability and resistance to fire risk.
Can I charge a portable power station while driving?
Yes. Every EcoFlow unit on this page includes a 12V car charging port that draws from your vehicle's accessory outlet while driving. Charge rate depends on the unit and the outlet, typically 100-200W of input, which adds roughly 100-200 Wh per hour of driving. The most efficient charging strategy on a multi-day trip is to charge from the vehicle while driving between camp sites, then top off with solar at camp.
