Best Portable Power Stations for Home Backup and Camping
An honest, spec-based comparison of the EcoFlow DELTA 2 Max, Jackery Explorer 2000 v2 and Goal Zero Yeti 1500X: capacity, output, battery chemistry, solar input and weight.

Short answer: for most households wanting outage backup that also camps well, a lithium iron phosphate (LFP) unit around 2,000 Wh is the keeper. The EcoFlow DELTA 2 Max leads on output and solar input; the Jackery Explorer 2000 v2 is the lightest of the three for similar capacity.
Side-by-side specs
Figures below are the makers' published specifications. We haven't bench-tested these units. Read the numbers as each brand's claims and compare them on the same terms.
| Spec | EcoFlow DELTA 2 Max | Jackery Explorer 2000 v2 | Goal Zero Yeti 1500X |
|---|---|---|---|
| Capacity | 2,048 Wh | 2,042 Wh | 1,516 Wh |

Our picks and who they suit
EcoFlow DELTA 2 Max
The highest output and the most solar input of the three. It suits anyone who wants to run a fridge, a sump pump or a microwave through an outage and recharge quickly from panels. Expansion batteries let it grow to just over 6 kWh, which matters if outages where you live last more than a day.
Why it stands out
- 2,400 W continuous, 4,800 W surge
- Up to 1,000 W solar input
- LFP chemistry, rated 3,000 cycles
Trade-offs
- Heaviest here at about 50 lb
- The most solar capacity in the group is wasted unless you buy enough panels
Jackery Explorer 2000 v2
Almost the same capacity as the EcoFlow at roughly 10 lb less. It has the longest rated cycle life (4,000 cycles to 70%) and Jackery publishes a UPS-style switchover of about 20 ms. That's handy for a modem or router, but Jackery itself says not to rely on it for servers or workstations.
Why it stands out
- About 17.9 kg / 39.5 lb for 2,042 Wh
- Three AC outlets at 2,200 W total
- Long published cycle life
Trade-offs
- Solar input tops out at 400 W, so solar recharges are slow
- No USB-C charging input, per Jackery's spec sheet
Goal Zero Yeti 1500X
A long-standing model with a broad accessory ecosystem and a 12 V high-power port that van and RV builders like. Its NMC battery is rated for far fewer cycles than the two LFP units. If you'll cycle it often, the LFP models are the better long-term value. For occasional backup, cycle count matters less.
Why it stands out
- 600 W solar input
- Regulated 12 V high-power port (up to 360 W)
Trade-offs
- Smallest capacity here
- NMC chemistry with a lower rated cycle life
- The included wall charger is slow (about 14 h, per Goal Zero)
How to choose
1. Size by watt-hours, not hype
Add up what you need to run and for how long. A fridge that averages about 60 W over a day uses about 1.4 kWh in 24 hours. Inverters lose some energy, so plan on roughly 85% of the rated capacity being usable.
2. Check surge, not only continuous output
Motors in fridges, pumps and power tools draw a short spike on start-up. Compare that spike with the station's surge rating.
3. Prefer LFP if you'll cycle it often
LFP (LiFePO4) cells are typically rated for thousands of cycles, against hundreds for NMC. For weekend camping plus outage backup, LFP is the safer long-term bet.
4. Match solar input to the panels you'll actually buy
A 1,000 W input only helps if you own about 1,000 W of panels. Rated panel watts are ideal-condition numbers, so expect less in real sun.
5. In Canada, check cold-weather limits
Most units won't charge below about 0 °C. Store and charge them indoors in winter, and check each model's published charging temperature range.
FAQ
Can a power station replace a gas generator?
For short outages and essential loads, often yes, and it runs indoors with no fumes. For multi-day whole-home loads, you'll need expansion batteries, solar, or a standby generator.
Can I run a space heater on one?
Technically yes, but a 1,500 W heater will empty a 2 kWh unit in about an hour. It isn't a practical use.
Are prices the same in Canada and the US?
No. Prices, bundles and warranty terms vary by country and retailer, so check the store for your country.
