Published: August 2026 — Three portable power stations, three price tiers, three very different use cases. Here's how they actually stack up after months of vanlife testing.
Every vanlifer eventually asks the same question: how much battery do I actually need, and which one is worth the money? Marketing pages make it look simple — bigger Wh number equals better — but the reality is that watts-per-dollar, chemistry, inverter size, charging speed, weight, and warranty all matter more than a raw capacity spec.
This guide compares three of the most-recommended portable power stations for 2026 builds: Goal Zero's Yeti 500X (compact LiFePO4 for weekend rigs), Jackery's Explorer 1000 Plus (the do-everything mid-tier), and EcoFlow's Delta 2 Max (the fast-charging heavyweight). By the end you'll know which one belongs under your bench — and whether you're overspending or underspending for your actual use case.
30-second answer
Weekender or Starlink-and-laptop only: Goal Zero Yeti 500X. Full-time vanlife with a fridge and occasional AC: Jackery Explorer 1000 Plus. Multi-day boondocking with induction cooking, a portable AC, or CPAP + fridge + laptops: EcoFlow Delta 2 Max.

Goal Zero Yeti 500X: the compact specialist
The Yeti 500X is the smallest of the three and the most focused. 505Wh of LiFePO4 storage, a modest 300W pure sine inverter, weighs less than a full water jug at 12.9 lb, and fits under a passenger seat.
What it's good for: Starlink Mini plus laptop plus phone charging for a full day. Small 12V fridge overnight (Dometic CFX3 45 will drain it in about 14-18 hours). CPAP overnight. Camera batteries. Basically, the electronics side of a weekend van build without any heating, cooking, or air conditioning.
What it can't do: run a coffee maker (most pull 1000W+), an induction cooktop, a hair dryer, or a portable AC. The 300W inverter caps you. If you need more than a laptop-scale AC load, look at the Jackery.
Real-use notes: the LiFePO4 chemistry means 3,000+ cycles to 80% capacity, so this thing will still be at 80% health after 8 years of daily use. Goal Zero's build quality remains excellent — metal handle, quiet fans, real 12V regulated output. The app connectivity is minimal but the display is clear.
Jackery Explorer 1000 Plus: the sweet spot for full-timers
The Jackery 1000 Plus is the one most full-time vanlifers actually end up with. 1,264Wh gets you two days of laptop plus fridge plus Starlink without stress. The 2,000W pure sine inverter runs everything short of an air conditioner — you can plug in a $60 microwave, a coffee maker, a heat gun for repairs, or a small induction cooktop.
Charging is where Jackery caught up in the last two years. The 1000 Plus recharges from AC in about 1.7 hours — useful at a friend's house or overnight at a paid campsite. It accepts up to 400W of solar input, which pairs well with a 200W foldable panel plus a small rooftop panel for daytime top-ups.
The modular expansion (up to 5kWh with add-on packs) is the underrated feature. Start with the base unit; add a battery pack a year later when you know your usage. Beats buying a bigger unit twice.
EcoFlow Delta 2 Max: the heavy hitter
The Delta 2 Max is the biggest of the three at 2,048Wh with a 2,400W inverter (3,100W with X-Boost). It's the only one that will comfortably run a small window AC unit, a full-size microwave, or a 1500W induction cooktop for a real meal.
Where it really separates is the X-Stream fast charging: 0-80% in about 43 minutes from a wall outlet. Plug it in for a lunch stop and drive off nearly full. Solar input tops out at 1,000W (500W per port), so a large solar suitcase can meaningfully recharge it in a day.
The tradeoff is weight and cost. 51 pounds is a lot. It lives in one place in your build — you're not moving this between the van and a picnic table. And at $1,700-1,900 it's the most expensive of the three, though the cost-per-watt-hour math ($0.88/Wh) is actually similar to the Jackery.
Cost-per-watt-hour: the real value math
The Goal Zero looks great until you divide dollars by watt-hours: $1.39/Wh. That's 60% more expensive per unit of storage than the Jackery or EcoFlow. You're paying for portability, not capacity.
Jackery 1000 Plus and EcoFlow Delta 2 Max come out nearly identical at $0.87 vs $0.88 per Wh. At that point the choice is about inverter size (Jackery 2000W vs EcoFlow 2400W with 3100W boost), weight tolerance (32 lb vs 51 lb), and charging speed (1.7hr vs 1.1hr).
Monitoring the whole system
Whichever power station you choose, if you also have a house battery bank, you should monitor state of charge and daily draw with a shunt-based monitor like the Victron BMV-712. Portable power stations do the monitoring for their own internal cells, but if you have a lithium house bank feeding your fridge and lights separately, you need real-time SoC to avoid deep discharges. Bluetooth logging over weeks tells you exactly where your amp hours are going.
Which one should you buy?
Buy the Goal Zero Yeti 500X if: you weekend, you want a portable unit you can grab and carry, your loads are laptop/phone/Starlink only, or it's a supplement to a bigger fixed house bank.
Buy the Jackery 1000 Plus if: you live in the van, you want to run a fridge overnight plus laptops plus occasional 1500W appliances, you value the expansion path to 5kWh later, or you want the best cost-per-Wh with reasonable weight.
Buy the EcoFlow Delta 2 Max if: you run an AC unit, you cook on induction, you have 500W+ of solar to feed it, or you want the fastest possible AC recharge for house-to-house transit.
Frequently asked questions
Can I run a portable AC on any of these?
The Yeti 500X: no. The Jackery 1000 Plus: a 5,000 BTU window unit on ECO mode for about 90 minutes. The EcoFlow Delta 2 Max: same 5,000 BTU unit for 3-4 hours, or an 8,000 BTU on ECO for about 2 hours. For actual overnight AC you need a 3kWh+ setup and probably an efficient DC-powered unit.
Are these safe to leave charging overnight?
Yes — all three have overcharge, overheat, and short-circuit protection built in. LiFePO4 chemistry is the safest lithium chemistry for consumer use (much lower thermal runaway risk than NMC). You can leave any of them plugged in indefinitely without damage.
How long will they last before capacity degrades?
All three use LiFePO4 with 3,000-4,000 cycle ratings to 80% of original capacity. If you fully cycle once per day, that's 8-11 years before you're at 80%. Practically speaking, the electronics will fail before the battery does.
What about pairing with solar?
The Yeti 500X caps at 120W of solar — enough for a 200W panel bled down. The Jackery accepts up to 400W. The EcoFlow accepts up to 1,000W across two ports. Match your solar suitcase to your unit: don't buy a 400W panel for a Yeti 500X, and don't buy a 100W panel for a Delta 2 Max.
Can I use these to charge from my alternator while driving?
All three accept 12V input, but stock car chargers only deliver 60-100W (roughly 8A). To meaningfully recharge from your alternator, add a DC-DC charger like the Renogy 40A that pushes 40 amps directly into the station's DC input — that gets you a full recharge on a half-day of driving.
