Best Overall
EcoFlow DELTA 2
The best all-round portable solar generator at this price — fast charging, solid output, and a genuinely useful app.
Capacity
1024Wh
AC Output
1800W
Surge
2700W (X-Boost)
Weight
12kg / 26.5lbs
Pros
- ✓0–80% AC charge in 80 minutes — fastest in class at this capacity
- ✓X-Boost handles appliances up to 2700W by managing power draw
- ✓LiFePO4 battery with 3000+ cycles to 80% capacity
- ✓140W USB-C port covers fast charging for laptops and phones simultaneously
- ✓EcoFlow app is the best in the category — energy monitoring, scheduling, remote control
Cons
- ✗500W solar input means 4–8 hours for a full solar recharge depending on conditions
- ✗Not expandable — if you outgrow 1024Wh you'll need a different unit
The DELTA 2 runs a full-size fridge (150W) for about 5.8 hours, a CPAP at 45W for around 19 hours without a humidifier, or a laptop for 13–15 hours. Those aren't marketing numbers — that's the runtime formula: 1024Wh × 0.85 efficiency ÷ load watts. The X-Boost feature is genuinely useful: it lets the unit power devices rated up to 2700W (a microwave, coffee maker, or small power tool) by slightly reducing their performance, which is better than the alternative of just not running them at all.
The one real limitation is solar recharge speed. At 500W max solar input, you need a full day of good sun to recharge from flat. For camping or occasional outages that's fine. For van life where solar is your primary source, step up to the DELTA 2 Max (1000W solar input) or the Bluetti AC200L (1200W).

Jackery Explorer 1000 Plus
More capacity and higher surge wattage than the DELTA 2 at the same price — the better choice if you're running power-hungry appliances.
Capacity
1264Wh
AC Output
2000W
Surge
4000W
Weight
14.1kg / 31.1lbs
Pros
- ✓1264Wh capacity beats the DELTA 2 by 240Wh at the same MSRP
- ✓4000W surge wattage is best-in-class at this tier
- ✓LiFePO4 with 4000+ cycles — better longevity than the DELTA 2
- ✓Expandable up to 5kWh with additional battery packs
Cons
- ✗AC charge time (~1.8 hrs full) is slower than EcoFlow's 80-minute fast charge
- ✗Jackery app is functional but significantly less polished than EcoFlow
- ✗400W solar input is lower than the DELTA 2's 500W
At the same $999 MSRP, the Jackery Explorer 1000 Plus offers 240Wh more capacity and a much higher surge rating (4000W vs 2700W). That surge matters if you're running appliances with compressor motors — fridges, AC units, power tools — where the startup draw spikes well above steady-state. If you're not AC fast-charging daily and the app quality doesn't matter to you, the Jackery is arguably the better value. Full breakdown in our Jackery Explorer 1000 Plus review and head-to-head comparison.
Best Compact
EcoFlow RIVER 2 Pro
The best compact solar generator under $500 — light enough to carry one-handed, with enough capacity for a weekend of serious use.
Capacity
768Wh
AC Output
800W
Surge
1600W (X-Boost)
Weight
7.8kg / 17.2lbs
Pros
- ✓7.8kg makes it genuinely portable for one person
- ✓X-Boost runs devices up to 1600W despite the 800W nameplate

You can't run a microwave or space heater for long, but for electronics, medical devices, and small appliances it covers a full weekend easily. See our full EcoFlow RIVER 2 Pro review.
Best Mid-Range
Bluetti EB70S
A solid mid-range option with 4 AC outlets — but only worth buying on sale, since the EcoFlow RIVER 2 Pro beats it at full price.
Capacity
716Wh
AC Output
800W
Surge
1400W
Weight
9.7kg / 21.4lbs
Pros
- ✓4 AC outlets — more than any competitor in this size class

Jackery Explorer 300 Plus
The lightest unit with real AC output — right for day trips, car camping weekends, and phone/laptop charging.
Capacity
288Wh
AC Output
300W
Surge
600W
Weight
3.75kg / 8.3lbs
Pros
- ✓3.75kg — lightest LiFePO4 unit with AC output on the market

288Wh handles about 4.5 hours of laptop use, 6 phone charges, or a 100W fan for 2.5 hours. It won't run a fridge overnight or a microwave for more than a few minutes. Be clear-eyed about what you're buying here: it's a capable travel battery, not a backup power system. See our full Jackery Explorer 300 Plus review.
Best High-Capacity
Jackery Explorer 2000 Plus
The best high-capacity portable generator for serious home backup and RV use — 3000W continuous handles nearly any appliance.
Capacity
2042Wh
AC Output
3000W
Surge
6000W
Weight
28kg / 61.7lbs
Pros
- ✓3000W continuous output — runs power tools, window AC, microwave without issue
- ✓6000W surge covers most compressor-motor startup spikes
- ✓LiFePO4 with 4000+ cycles
- ✓Expandable to higher capacity with additional packs
Cons
- ✗28kg requires two people or a cart to move
- ✗800W solar input takes a full day to recharge from flat (multiple panels needed)
- ✗Not truly portable — this is a home/RV unit
At 2042Wh and 3000W output, this handles a full-size fridge for ~11.5 hours, a window AC for 3–4 hours, or a sump pump through most short flooding events. On sale at $1,299 it's exceptional value for home backup. Don't buy it expecting to carry it to a campsite — 28kg is a two-person job. Full details in our Jackery Explorer 2000 Plus review.

The single most important number is capacity in watt-hours (Wh). This tells you how much total energy the unit stores. To estimate what you need, add up the wattage of every device you plan to run, multiply by the hours you'd run them, and divide by 0.85 (efficiency factor). That's your minimum capacity.
Capacity tiers and what they actually power
Under 500Wh: Phones, laptops, LED lights, small fans. Not for fridges or cooking appliances. Right for day trips and weekend car camping.
500Wh–1200Wh: The most useful tier. Covers a CPAP for multiple nights, a mini fridge for a day, most electronics simultaneously. Right for camping, travel, and short outages.
1200Wh–2500Wh: Serious home backup. Keeps a full-size fridge running for 8–13 hours, runs a window AC for a few hours, handles power tools. Right for extended outages and full RV setups.
Battery chemistry: always choose LiFePO4
Every pick on this list uses LiFePO4 (lithium iron phosphate) chemistry. It lasts 2,000–4,000+ cycles to 80% capacity vs 300–500 for older NMC (lithium-ion) batteries. At one cycle per day, a LiFePO4 unit lasts a decade or more before significant degradation. An NMC unit at the same usage rate can degrade noticeably within 2–3 years.
Solar input matters if you're off-grid
For camping or home backup, solar recharge speed may not matter — you'll charge over AC most of the time. For van life or off-grid, the solar input wattage is critical. The DELTA 2's 500W input means 2–4 hours of recharge per peak sun hour. The Bluetti AC200L's 1200W input means 5–6 hours of sun can fully recharge 2048Wh on a good day.
Frequently Asked Questions
What is the best portable solar generator?
The EcoFlow DELTA 2 is the best portable solar generator for most buyers in 2026. It offers 1024Wh capacity, 1800W AC output, and charges from 0–80% in 80 minutes. It goes on sale regularly for $749–849, making it the best value at its tier.
How long will a 1000Wh solar generator run a refrigerator?
A 1000Wh solar generator runs a full-size refrigerator (100–150W draw) for approximately 5.7–8.5 hours, accounting for ~85% inverter efficiency. A mini fridge or 12V cooler drawing 40–60W will last 14–21 hours on a full charge.
Can a portable solar generator power a house?
A portable solar generator can power essential appliances during an outage — fridge, lights, phone charging, CPAP, small TV — but not a whole house. Whole-home backup requires units like the EcoFlow DELTA Pro (3600Wh, expandable to 25kWh) paired with the Smart Home Panel, or a dedicated home battery system.
Are solar generators worth it?
Yes, for most use cases. A $750–999 LiFePO4 solar generator covers camping, short outages, travel, and medical device backup with zero fuel cost and no maintenance. For long outages (48+ hours) where you need to run heavy loads continuously, a gas generator or a large home battery system is still more practical.
What is the difference between a solar generator and a power station?
They're the same thing — the terms are interchangeable. Both refer to a rechargeable battery unit with AC outlets, USB ports, and DC outputs. 'Solar generator' typically implies the unit can be charged from solar panels; 'portable power station' is the more technical term. All units on this list accept solar panel input.
How many solar panels do I need to charge a portable solar generator?
To recharge a 1000Wh unit in 4–5 peak sun hours, you need roughly 250–300W of solar panels (accounting for real-world MPPT efficiency of around 75% of rated output). Two 200W panels will recharge a 1024Wh EcoFlow DELTA 2 in a good sunny day. See our guide on how many solar panels you need for more detail.
What is the best solar generator for emergency backup?
The EcoFlow DELTA Pro (3600Wh, expandable) is the best solar generator for home emergency backup. It can run a fridge, lights, and device charging for 24+ hours, supports 240V with two units in split-phase, and connects to the EcoFlow Smart Home Panel for automatic switchover when the grid goes down.
