The best waterproof solar generator in 2026 is the Jackery Explorer 1500 Ultra, the only mainstream portable power station whose whole unit carries an IP65 rating: 1,536Wh, 1,800W, about $1,079. The runner-up is the Goal Zero Yeti 1500 at IPX4 (splash resistant). Most other units are unrated, or rate only the sealed battery pack inside, not the ports and inverter.
How we chose: Our picks are based on published specifications, pricing, warranty terms and owner reports. We only list water-resistance ratings the manufacturer publishes, and we say exactly what each rating covers.
What do IP ratings mean on a power station?
IP (Ingress Protection) codes follow the format IP[solids digit][liquids digit]. An "X" means that part was not rated.
| Rating | Solids | Water | Practical meaning |
|---|---|---|---|
| IPX4 | Not rated | Splashing from any direction | Light rain and splashes |
| IP54 | Dust protected | Splashing from any direction | Light rain, dusty sites |
| IP65 | Dust-tight | Low-pressure water jets | Heavy rain, hose spray nearby |
| IP67 | Dust-tight | Immersion to 1 m for 30 minutes | Brief dunking |
| No rating | Unknown | Unknown | Keep it covered and dry |
None of these ratings means a power station can sit in a puddle. Even on a rated unit, open ports and plugged-in cables are the weak point, so keep port covers closed when nothing is connected and keep plugs out of standing water.

| Jackery Explorer 1500 Ultra | IP65 | Whole unit | 1,536Wh | 1,800W | About $1,079 |
| Goal Zero Yeti 1500 | IPX4 | Whole unit, with port shields | 1,505Wh | 2,000W | About $1,500 |

Best overall: Jackery Explorer 1500 Ultra (IP65)
Jackery rates the Explorer 1500 Ultra IP65 dust-tight and water-jet resistant, and adds a drop-resistance claim (one meter), a bottom drainage design and an operating range of 5F to 113F. Specs from Jackery's Amazon listing:
- Capacity: 1,536Wh LiFePO4, 4,000+ cycles to 70%
- Output: 1,800W continuous, 3,600W peak for 5 seconds
- Solar input: 800W max, full in about 2.5 hours in ideal sun
- AC charging: full in about 1.5 hours
- Weight: 38.6 lb
- Warranty: 5 years (3 standard plus 2 extended)
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).
Runtime uses the formula runtime (hours) = rated Wh x 0.85 / average load (W), which leaves about 1,306Wh usable: roughly 29 hours for a 45W 12V cooler, 22 hours for a 60W laptop, 8.7 hours for a full-size fridge averaging 150W, or about 1.6 hours for an 800W pump. That suits boat decks, job sites, market stalls and rainy campsites where a unit has to sit outside.

Runner-up: Goal Zero Yeti 1500 (IPX4)
Goal Zero rates the current Yeti 1500 IPX4 for splashes and pairs it with an aluminum case, rubber bumpers and port shields to keep rain and mud out. It has 1,505Wh of LiFePO4 (4,000 cycles), a 2,000W inverter with 3,600W surge, four AC outlets and six USB ports including a 140W USB-C, and charges 0-80% from the wall in under an hour. IPX4 handles rain and splashes but not jets or immersion, so keep it off wet ground. At about 1,279Wh usable, it runs a 150W fridge for about 8.5 hours.

Best small unit: EcoFlow RIVER 3 (IP54 battery)
EcoFlow rates the RIVER 3's battery pack IP54 and describes the unit as fireproof and drop-resistant. The rating covers the battery, not the ports or electronics, so it is best described as more robust than most small stations rather than weatherproof. It has 245Wh, a 300W inverter (600W X-Boost), a 20 ms UPS and weighs 7.8 lb. With about 208Wh usable, it runs a 45W cooler for about 4.6 hours or charges phones and lights for a weekend.

Best 1kWh with a sealed battery: EcoFlow DELTA 3 Plus (IP65 battery)
EcoFlow says the DELTA 3 Plus battery pack is IP65 rated (splash, dust and oil resistant). As with the RIVER 3, that protects the cells, not the outlets and inverter, so the unit still needs cover in rain. It is a strong all-rounder otherwise: 1,024Wh, 1,800W (3,600W surge), 1,000W of solar input, a 10 ms UPS, 27 lb and expansion to 5kWh. About 870Wh usable runs a full-size fridge for roughly 5.8 hours.

How do you protect an unrated power station from rain?
Covers and placement
The cheapest fix is placement: under a table, awning, truck-bed cover or tarp, raised off wet ground on a board or rubber mat, with outlets facing away from wind-driven rain. Leave space around the vents, because power stations need airflow to stay cool.
Model-specific covers
Weather covers sized for popular models shed rain but do not seal ports. They extend outdoor use in drizzle; they are not a substitute for a rating.
Hard cases for boats and job sites
A hard case with a cable grommet protects a unit on a boat or work site, but it traps heat. Only run a station inside a case with ventilation, and never while charging at high power.
What should you look for?
A published rating, and what it applies to
Look for an IP code in the manufacturer's specifications, and read whether it applies to the whole unit or only the battery pack. Words like "rugged" or "weather resistant" without a code are not a rating.
Warranty terms
Warranties commonly exclude damage from misuse, and water exposure on an unrated unit can fall under that. Check the terms before you rely on any unit outdoors; our warranty comparison covers the main brands.
Your real use case
For home outages and weekend camping, keeping a station dry is easy and a rating matters little. For boats, markets, farms and construction sites, the Explorer 1500 Ultra's IP65 is worth paying for. See our boating and marine guide, best portable solar generators and van life and RV guide for more use-case picks.
For home outage backup rather than outdoor use, see our best solar generators for emergency preparedness, led by the 3,600Wh EcoFlow DELTA Pro.
Frequently Asked Questions
What IP rating should a solar generator have for outdoor use?
IP65 (dust-tight, resists water jets) is the strongest rating on a mainstream unit and suits boats, job sites and rainy camps. IPX4 or IP54 handles splashes and light rain. An unrated unit should be kept covered and off wet ground.
Is the Jackery Explorer 1500 Ultra really waterproof?
Jackery rates the whole unit IP65: dust-tight and resistant to low-pressure water jets. That is not submersion-proof, and open ports with cables plugged in are still vulnerable, but it tolerates rain and spray far better than unrated stations.
Are EcoFlow power stations waterproof?
Not as whole units. EcoFlow publishes IP ratings for some battery packs, such as IP65 on the DELTA 3 Plus pack and IP54 on the RIVER 3 battery, which protect the cells, not the outlets and inverter. Keep them covered in rain.
What does IP65 mean on a solar generator?
The 6 means dust-tight and the 5 means it withstands water from a 6.3 mm nozzle from any direction. It does not mean it can be submerged, which would need IP67 or IP68.
Is the Goal Zero Yeti 1500 weatherproof?
Goal Zero rates the current Yeti 1500 IPX4, meaning it resists splashing water from any direction, and adds port shields, an aluminum case and rubber bumpers. It is fine in light rain but should not sit in standing water or heavy downpours.
How do I protect my solar generator from rain while camping?
Put it under a table, awning, vestibule or tarp, raise it off the ground on a board or mat, face the outlets away from wind-driven rain and close unused port covers. Leave room around the vents so it can cool.
Can solar generators be used on boats?
Yes, with care. An IP65 unit like the Jackery Explorer 1500 Ultra tolerates spray best. Any unit needs ventilation, secure mounting and protection from standing water; IP ratings do not cover salt corrosion.
