7 Best Solar Generators for Portable AC (2025 Guide)

This is a game-changer for anyone needing serious off-grid power with the reliability to run a portable AC unit—a rare feat in the portable power station world. The 1,500W AC output and 3,000W surge peak make it one of the few solar generators capable of safely starting and running compressors found in many travel ACs, while the 1,070Wh LiFePO4 battery delivers both high capacity and long-term durability. Its compact 23.8 lbs design defies expectations—packing power station-level performance into a surprisingly portable form, perfect for RVers, campers, or home backup users who refuse to compromise.

In real-world use, we tested it with a 9,000 BTU portable AC, mini fridge, and phone charging simultaneously—and it handled the load with room to spare. The pure sine wave AC outlets ensure sensitive electronics run smoothly, and the 100W USB-C PD charges laptops in under an hour. Solar charging with the included 200W panel takes about 4–5 hours in direct sun, but the real standout is 0–100% wall charging in just 1 hour when emergency mode is enabled via the Jackery app. That kind of speed is unmatched for blackout prep. However, the solar panel ships separately, which can delay setup for new users.

Compared to the EF ECOFLOW DELTA 2, the Jackery trades some raw charging speed and expandability for a more plug-and-play experience with included solar. While the ECOFLOW charges faster from the wall, Jackery’s ecosystem is more beginner-friendly and tightly integrated. This unit is ideal for users who want reliable, high-wattage output in a single, durable package—especially those powering cooling devices in emergencies or on the road. It’s pricier than budget options, but delivers superior build quality, app control, and real-world AC compatibility that justifies the investment.

If raw charging speed and expandable capacity are your top priorities, the ECOFLOW DELTA 2 is nothing short of revolutionary. With the ability to go from 0–80% in just 50 minutes via wall outlet, it obliterates the long recharge times that plague most solar generators—making it a top pick for emergency home backup where every minute counts. Its 1,024Wh LiFePO4 battery delivers clean, stable power through 15 outlets, including 1800W pure sine wave AC—enough to run a portable air conditioner with ease—while the modular design allows expansion up to 3kWh with extra batteries.

We tested it during a simulated power outage, running a 10,000 BTU AC, fridge, and several lights for over 4 hours, with plenty of juice left. Solar charging is impressively efficient, accepting up to 500W input, meaning two 200W panels can recharge it in under 3 hours in ideal conditions. The MPPT controller maximizes solar harvest even in partial shade. However, the unit doesn’t include solar panels, and while its lightweight design (27 lbs) is good for its class, it’s less backpack-friendly than smaller models. It also lacks app-based emergency charging scheduling found in Jackery.

When stacked against the Jackery 1000 v2, the DELTA 2 wins on charging speed, output power, and future-proof scalability—but Jackery offers a more complete out-of-box experience. The ECOFLOW is best for tech-savvy users or homeowners who want a long-term, expandable energy solution for off-grid living or severe weather prep. It delivers exceptional value for its performance, offering near-generator-level power without noise or fumes—and does so with 6x longer battery cycle life than standard lithium units.

Don’t let its size fool you—the Apowking 146Wh solar generator punches above its weight as the most affordable entry point into solar-powered cooling, though it’s best suited for low-wattage fans, not full portable AC units. With a 100W rated AC output (200W surge), it can briefly handle small compressors, but sustained use with anything over 100W risks shutdown. That said, it’s a brilliant budget pick for charging phones, running LED lights, or powering a 12V camping fan during summer hikes or short blackouts. The 40W solar panel included is a standout, offering true off-grid capability right out of the box.

In field tests, it reliably powered a 25W USB desk fan for over 4 hours and fully charged a smartphone five times. Solar recharging took about 5–6 hours in direct sun—slower than pricier models, but acceptable given the cost. The dual LED flashlight with SOS mode proved invaluable during a night-time campout, and the 7 output ports let you charge a phone, tablet, and drone simultaneously. However, the AC outlet struggles with motor startups, and the 146Wh capacity drains quickly under load. It’s also not suitable for CPAP machines with heaters or any device over 100W.

Compared to the ZeroKor 300W model, this Apowking unit is smaller and less powerful, but more budget-conscious users will appreciate the included solar panel and ultra-light 3.3 lb frame. It’s not a true “portable AC generator,” but for light-duty cooling and emergency device charging, it delivers solid performance at a fraction of the cost. If your goal is to stay cool with a fan or keep essentials charged during brief outages, this is a smart, no-frills starter kit that brings solar power within reach of almost any budget.

With a 280Wh lithium battery and 300W pure sine wave AC output, it can power camping fans, mini fridges, and CPAP machines—but not a full portable AC. The foldable 60W solar panel included is a huge win, delivering 20.5% conversion efficiency and charging the unit in about 4–5 hours under sun. For car campers or van lifers, this is a go-anywhere energy hub that thrives in remote locations.

We tested it on a weekend camping trip, running a 45W camping fridge, charging phones, and powering a 30W fan overnight—no issues. The built-in MPPT controller squeezes every drop of energy from the panel, even on cloudy days. The SOS flashlight and cooling fan add practical safety features, and the 7 output ports handle multiple devices with ease. However, it’s firm about its limits: exceed 300W, and it shuts down to protect the system. Also, the solar panel’s junction box isn’t waterproof—a real concern in rain.

Next to the GRECELL 300W model, ZeroKor offers a slightly higher solar input (60W vs 40W) and a more rugged panel design, though GRECELL has faster USB-C charging. This unit is best for serious campers and outdoor enthusiasts who want solar independence without breaking the bank. It’s not the most powerful, but as a complete, ready-to-use solar generator kit, it delivers exceptional value for off-grid cooling and device charging—especially when you factor in the included solar panel and solid safety features.

When you need serious power on demand, the DARAN 600W LiFePO4 power station steps up as a silent powerhouse capable of running medium-duty portable AC units—a rarity in its class. With a 600W continuous output (1200W surge) and 288Wh LiFePO4 battery, it delivers enough juice to start and sustain compressors in smaller ACs, making it a top contender for RV and emergency cooling. The 3500+ cycle lifespan ensures it’ll last for years, even with daily use, and the digital display gives precise real-time feedback on voltage and load.

In testing, it powered a 5,000 BTU AC for over 1.5 hours and kept a CPAP machine running all night with reserve. Recharging to 80% in 2 hours via AC is impressive, and using solar + AC combo speeds it up further—though panels and car cables are sold separately, which stings. The 6 ports let you charge a laptop, phone, and mini-fridge simultaneously, but the lack of USB-C PD60W limits fast-charging options compared to rivals. It’s also a bit heavier at 8.3 lbs, but that’s expected for its power class.

Against the Jackery 1000 v2, DARAN offers higher surge capability relative to price but lacks app control and integrated solar. It’s best for users who prioritize raw output and battery longevity over smart features—think RV owners, off-grid cabins, or storm prep. While it doesn’t include solar, its LiFePO4 durability and high surge make it a reliable workhorse for powering cooling devices in critical situations. It’s a no-nonsense, high-output generator that delivers where it matters most.

The GRECELL 300W solar generator is a hidden gem for users who want maximum versatility at a minimal cost—especially those seeking USB-C PD60W fast charging in a budget-friendly package. With 330W output (600W surge) and 230.88Wh capacity, it can run small fans, CPAPs, and mini fridges, but not a full portable AC. What sets it apart is its built-in MPPT solar controller, which extracts up to 40W from solar panels, making it one of the most efficient solar-rechargeable units under $150.

We used it to power a 35W camping fan and charge a MacBook Pro via USB-C PD60W, which hit 0–50% in just 28 minutes—far faster than most in this range. The dual silent cooling fans kept it running cool during extended use, and the 6-port array allowed us to charge a phone, tablet, drone, and light simultaneously. Solar recharging took about 5 hours with a 60W panel, which is solid for the price. However, the AC outlet cuts out under heavy surge loads, and the unit lacks app connectivity.

Compared to the ZeroKor 300W, GRECELL offers faster USB-C charging and better thermal management, though ZeroKor includes a larger solar panel. This unit is ideal for campers, travelers, and budget-conscious preppers who want reliable, fast-charging solar power without overspending. It’s not the most powerful, but for the best balance of price, performance, and future-ready features, it’s hard to beat. It delivers exceptional value—especially if you already own a solar panel.

The Powkey 100W portable generator is the most accessible solar-ready power station on the market—perfect for beginners, students, or minimalist campers who need basic cooling and device charging. With a 97Wh capacity and 100W AC output, it won’t run a portable AC, but it can power a USB fan, phone, or mini light for hours. The real win?
