The best budget solar generator in 2026 is the BLUETTI Elite 100 V2 (about $499): a full 1,024Wh LiFePO4 battery, 1,800W output and 1,000W of solar input for under $500. The EcoFlow DELTA 3 Classic (about $499) is the alternative if you want faster wall charging and EcoFlow's app, and the EcoFlow RIVER 2 Pro (768Wh, about $389) and Jackery Explorer 300 (292Wh, about $259) cover tighter budgets.
Our picks are based on published specifications, pricing, warranty terms and owner reports. Specs are from each manufacturer's US product page or Amazon US listing, checked in September 2026. Prices change often.
What does under $600 get you in 2026?
Much more than it used to. A 1kWh LiFePO4 unit now costs about $500, which is enough to run a modern full-size refrigerator for roughly 11-14 hours (1,024Wh x 0.85 / 60-80W average) or a 40W CPAP for about 21 hours. What budget units still cannot do: run a space heater or window AC for more than an hour or two, or cover multi-day home backup without solar panels.
The figures here use planning draws: a conservative 150W average for a full-size fridge (a new ENERGY STAR model averages closer to 63W, so expect longer runtimes) and a conservative 40W for a CPAP (ResMed's battery guide lists about 8 to 20W for an AirSense 10 with its humidifier off, measured through ResMed's 12V DC converter, so expect longer CPAP runtimes than shown, especially from a 12V outlet, and up to about 55W with the humidifier at its highest setting, or about 67W with a heated tube as well).

BLUETTI Elite 100 V2: best overall value
For about $499 you get 1,024Wh, 1,800W continuous with 3,600W surge (Power Lifting runs heat-based appliances up to 2,700W at reduced power), 1,000W of solar input that BLUETTI rates at 70 minutes to full, a 140W USB-C port, a 10ms UPS switchover and a 4,000-cycle rating, in a 25 lb box. The trade-off is no expansion. See our Elite 100 V2 review.

EcoFlow DELTA 3 Classic: best for fast wall charging
The same 1,024Wh and 1,800W (3,600W surge) for about $499, with X-Boost to 2,600W, 1,400W wall charging (80% in 45 minutes), a 10ms switchover, 500W of solar input, 100W and 30W USB-C ports and a 5-year warranty with app registration. It has half the Elite 100 V2's solar input but EcoFlow's app and accessory range. See our DELTA 3 Classic review.

Jackery Explorer 1000 v2: lightest 1kWh
At 23.8 lb it is the lightest 1kWh unit here, with 1,070Wh, 1,500W (3,000W surge), three AC outlets and a 100W USB-C port. It has the lowest output and solar input (400W) of the 1kWh group. See our Explorer 1000 v2 review.

BLUETTI AC180: most capacity for the money
The AC180 has the most capacity here (1,152Wh) with 1,800W output (Power Lifting to 2,700W), 11 outlets including four AC, 1,440W wall charging (full in about an hour) and 500W of solar. Its UPS switchover is rated at 20ms, slower than the Elite 100 V2 and DELTA 3 Classic.

Anker SOLIX C800X: best starter solar kit
Sold with a 100W folding panel for about $430, the C800X has 768Wh, 1,200W (1,600W peak) across 10 ports, up to 300W of solar input and built-in camping lights. Add a second panel to use the full 300W input.

EcoFlow RIVER 2 Pro: best under $400
768Wh and 800W (X-Boost to 1,600W) for about $389 on Amazon, with a 70-minute full charge from the wall. The 220W solar input is the weak spot: a full solar charge takes most of a sunny day.

Jackery Explorer 300: best ultralight
At 7.5 lb and about $259, the Explorer 300 (292Wh, 300W, 600W surge) charges phones, laptops, cameras and lights, and runs a CPAP for part of a night. Jackery rates it at 80% in about 2.8 hours from a 100W panel. It will not run a refrigerator for long.

What happened to the Jackery 300 Plus, BLUETTI EB70S and Anker C800?
All three are discontinued. Jackery's Explorer 300 now fills the ultralight slot, the BLUETTI AC180 replaces the EB70S with far more capacity and output, and the Anker SOLIX C800X replaces the C800. The Jackery Explorer 300 Plus review and Anker C800 review remain on the site for owners of those models.
Which should you buy?
Most people: the BLUETTI Elite 100 V2, for 1kWh and 1,000W solar under $500. Fast wall charging and EcoFlow's ecosystem: the DELTA 3 Classic. Lightest 1kWh: the Jackery Explorer 1000 v2. Under $400: the RIVER 2 Pro. Backpacking or a second unit: the Jackery Explorer 300. If you need more than 1kWh, see our best portable solar generators, best solar generators under $500 and camping rankings.
Amazon-first brands go lower still: the STARYLINE 1000W sells 1,024Wh of LiFePO4 for about $330, and GRECELL's 2400W offers 1,843Wh for about $500. The STARYLINE review and GRECELL review cover what those prices leave out. For every budget brand side by side, see cheap Amazon power stations compared.

Frequently Asked Questions
What is the best solar generator under $500?
The BLUETTI Elite 100 V2 at about $499: 1,024Wh of LiFePO4, 1,800W output (3,600W surge), 1,000W of solar input and a 10ms UPS switchover. The EcoFlow DELTA 3 Classic (about $499) is the close alternative with faster wall charging.
Can a budget solar generator run a refrigerator?
A 1kWh unit can. It runs a modern full-size fridge averaging 60-80W for about 11-14 hours, or about 5.8 hours at a conservative 150W average. A 768Wh unit gives about 4.4 hours at 150W, and a 292Wh unit under 2 hours.
How long does the EcoFlow RIVER 2 Pro last on a charge?
About 10.9 hours on a 60W laptop, 16.3 hours on a 40W CPAP and 65 hours on a 10W router (768Wh x 0.85 / load). EcoFlow rates it at 70 minutes for a full charge from the wall.
Is the Jackery Explorer 300 worth buying?
For light, portable use, yes. At 7.5 lb and about $259 it charges phones, laptops and cameras and runs a 40W CPAP for about 6 hours. It is too small for refrigerators or anything over 300W.
What happened to the Jackery 300 Plus, BLUETTI EB70S and Anker C800?
All three are discontinued. The Jackery Explorer 300, BLUETTI AC180 and Anker SOLIX C800X are the current models in those slots.
How much solar input do budget solar generators have?
It ranges widely: 220W on the EcoFlow RIVER 2 Pro, 300W on the Anker SOLIX C800X, 400W on the Jackery Explorer 1000 v2, 500W on the EcoFlow DELTA 3 Classic and BLUETTI AC180, and 1,000W on the BLUETTI Elite 100 V2.
Can a budget solar generator power a CPAP machine?
Yes. At a conservative planning draw of 40W, a 768Wh unit runs a CPAP for about 16 hours (two nights) and a 1kWh unit about 22 hours. ResMed lists about 8 to 20W for an AirSense 10 without its humidifier, so expect longer; with the heated humidifier at its highest setting (about 55W), expect about 12 and 16 hours.
