EnginStar Solar Generator, 300W Portable Power Station, 296Wh Lithium Battery Backup w/Two 110V Pure Sine Wave AC Outlet for Camping Road Trip RV, 80000mAh Sufficient Power Supply for Blackout

Been working great so far. We haven’t had full sun since I bought it, but it still charges with the solar panels, just slower. I’m sure it’ll be much faster in direct sunlight. I was also surprised how big the solar panel was, and it easily folds up to a smaller size for storage and travel. It comes with lots of adapters. Has AC outlets, USB-A, USB-C, and other ports for charging different devices. Overall, very happy with it.

Works exactly like it should. Charges fast, lasts long, and powers all my small devices with no problem. Lightweight, quiet, and reliable. Definitely worth the price. And amazing customer service 😊 thank you for your assistance

fully charged an oxygen concentrator so our patient could stay out longer than the 2 hours the regular battery lasted

Nice, solid build I really like the little USB-Cord that is included but it is hard to remember that is not a carrying strap; it's just there so you don't lose it. But it does look and feel like a carrying strap. That's a "me" problem, ha ha. There is also an illumination source, kinda like a lantern or flashlight. A bright LED face that has a few modes. VERY bright is one, a little dimmer is one, and the last mode is flashing S O S in Morse code! It's so cool and according to the face it's only pulling 2 watts. That makes sense with modern LEDs. I love that you can see your power draw, too! It's neat! The unit is well built, and a bit bulky but I fit it in my backpack with my tablet and my laptop as well as my other items. So it's not prohibitively bulky, depending on how much stuff you think you need in your backpack. When I was in class and I saw that my laptop was at about 45% I decided to pull this monster out of the backpack and charge up. The other kids in class have to sit on the floor plugged in to one of the two or three available power receptacles when their batteries get low. Anyway, I used this power station to bring up the battery level of my laptop and it did the job. It restored my laptop to a full charge, which happened in about a half hour, give or take. In doing so it depleted its own charge down to nothing, so that was that with using the charger. For its bulky size I would have expected it to fully charge my laptop two or three times between needing to be charged. But all I got out of it was one half of a laptop top off. So, not as much power or usefulness as I expected from the product description.

In January 2025 three Portable Power Station were purchased for basic power needs. They are utilized to power small electronics like handheld and GoPro cameras. These stations are user friendly and convenient with the different ports. The design and weight, makes them suitable for use in confined and tight areas. This is a product that would be purchased again and is definitely recommend.

This EnginStar 300W power station has become my reliable companion for camping trips and emergency backup power. At 6.5 pounds and compact dimensions, it strikes an excellent balance between portability and capability that makes it genuinely useful for outdoor adventures. The pure sine wave AC outlets provide clean power that safely runs sensitive electronics like laptops and cameras without the compatibility issues found in modified sine wave units. I've successfully powered my laptop for several hours, charged multiple devices simultaneously, and run a small LED light setup without any performance issues or device problems. Battery capacity at 296 watt-hours proves adequate for weekend camping scenarios. Realistic runtime includes charging phones 15-20 times, running a laptop for 4-6 hours, or powering LED lights for multiple evenings. The LCD display clearly shows remaining capacity and power draw, helping with energy management in the field. The multiple charging options add real versatility. Wall charging takes about 7 hours as advertised, car charging works well during travel, and solar compatibility (panel sold separately) provides off-grid recharging capability. Having all three options covered means you're rarely stranded without power options. Build quality feels solid for the price range. The housing withstands typical camping abuse, and the various ports and switches operate smoothly. The integrated LED light serves as a useful emergency illumination source, though it's not particularly bright. The protection systems appear to function properly - the unit has safely handled various load scenarios without overheating or shutdowns. Battery management seems effective, maintaining consistent performance through numerous charge cycles. Limitations include the 300W power ceiling, which rules out higher-draw appliances like microwaves or space heaters. The cooling fan can be audible during heavy loads, and charging time is relatively long compared to some competitors. The maintenance requirements are clearly explained and reasonable - periodic charging prevents deep discharge damage, and proper storage guidelines help preserve battery longevity. Bottom Line: Excellent portable power solution for camping, emergency backup, and mobile electronics needs. The combination of capacity, portability, and multiple charging options makes it valuable for outdoor enthusiasts and emergency preparedness. Best for: Weekend camping, RV trips, emergency backup power, outdoor photography, remote work setups

Took a gamble on this as we were going off grid camping and needed something to power my Airsense 10 cpap. From reviews it was recommended to turn off humidifier, which I did. I have to say my worries were gone. After two nights of 7-8 hours per night, o ly one bar was used. Based on that I can go 3-4 nights wirh my cpap. I did try to see if it would power our single serve Keurig. Although coffee maker powered on, it shut off prior to brewing. We think it couldn't support the load. This doesn't impact my review as I bought it to support my cpap and it exceeded expectations.
