Not every problem needs
the biggest battery
I've been running on solar power for years — in a van, through grid outages, and in 100°F New Mexico desert sun. This page is about helping you figure out what you actually need, so you don't overspend, underbuy, or end up with a station that bakes itself in your back seat.
The first question I ask anyone who reaches out about power gear: what happens if you run out of juice? Is it annoying, or is it dangerous? Are you keeping a laptop charged or keeping a CPAP running? That one answer shapes everything else.
Pick the situation closest to yours and I'll point you toward what I'd actually build — not what has the best margin.
Living in a van or doing serious overlanding
Daily solar recharge, a 12V fridge running 24/7, Starlink, maybe a diesel heater. You need something that handles desert heat and mountain cold — sometimes in the same week.
Van life power guide →Car camping, overlanding, or long weekends
Top up devices, run some lights, maybe keep a cooler cold. Portability matters. You don't need to spend $2,000 for three days in the Jemez Mountains.
See camping picks →Grid outages, medical equipment, or home backup
Power outages hit differently when someone in your house depends on medical equipment. UPS switchover speed, pure sine wave output, and runtime matter far more than peak wattage.
Medical backup guide →Building an off-grid or hybrid solar setup
One panel isn't a system. Compatible input ceilings, real-world desert output, and correctly sized wiring — this is where most people make expensive mistakes.

I've had all four brands in my setup at one point or another. Here's the real picture — including where each one has limits. Every serious unit here uses LiFePO4 chemistry, which means 3,000–5,000 charge cycles and cells that don't go into thermal runaway at 105°F. That matters more than the name on the side.
| Brand | Genuinely good at | Where it has limits |
|---|---|---|
| EcoFlow | Fast innovation, best app experience, widest accessory ecosystem. The Delta 2 Max is still my daily driver in the van. | Higher price for equivalent capacity compared to some competitors.Worth it if you're building around the EcoFlow ecosystem |
| Jackery | Most reliable for pure portability. The Explorer 1000 Plus is the easiest station I've ever recommended — great if you just want it to work without thinking about it. | Slower solar input ceiling than competitors. App is basic.Not the right fit for a serious built-in van setup |
| Anker SOLIX | Best cold-weather performance. The F3800's output is unmatched at its price. Self-heating cells are a real feature — not marketing. | Heavier units. Fewer accessories than EcoFlow's ecosystem.Right pick if cold weather or raw output is your priority |
| Bluetti | Best modular approach. The AC300 + B300 stack lets you grow the system over time without replacing the core unit. Smart for home backup. | Bulkier builds. App has lagged behind competitors.Better suited to home installs than van life portability |
Want to see these go head-to-head in real conditions? The heavy-duty battle and mid-range battle are the most thorough comparisons on the site — thermal tests, true capacity, and real desert performance.
These aren't sponsored bundles. They're the configurations I'd put together for a friend — with honest notes on the tradeoffs and roughly what you'd spend.
Just get out there without overthinking it
The Jackery Explorer 1000 Plus paired with the SolarSaga 100W panel. 26 lbs, charges fully in about 7 hours of New Mexico sun, handles lights, phones, a small fan, and a cheap 12V cooler all weekend.
If you want lighter and cheaper and you're really just charging devices — the Anker C800 at $449 is genuinely solid. Zero complaints in dusty conditions.
The setup I'd build if I were starting over today
EcoFlow Delta 2 Max with two of the 220W bifacial panels. Two panels wired together puts out ~440W on a good day — enough to fully recharge by early afternoon and run indefinitely in summer. Handles a 12V fridge, CPAP, laptop, and lighting without trouble. It's 50 lbs, manageable solo.
Doing serious mountain winters or need Starlink-level draw? Step up to the Anker F3800. The self-heating cells are worth it when you wake up in a frozen van in November.
When losing power isn't just inconvenient
EcoFlow Delta Pro paired with the 400W rigid panel on the roof. The 30ms UPS switchover means medical devices never notice the grid going down. 3.6kWh runs a CPAP for 4–5 nights, keeps an insulin fridge going for 40+ hours, and powers lights and devices through a multi-day outage.
Running an oxygen concentrator? That's 550W continuous draw — you need the Delta Pro Ultra or F3800, and a conversation with an electrician about a transfer switch.
