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

I purchased this Power Station to power my CPAP while camping. I tested other out with my CPAP. I have a Resmed Airsense 11 CPAP with Humidity and heated hose. I plugged in my CPAP using the 110v outlet on the power pack. Turned on the power pack and then the CPAP. I disabled the Humidity and heated hose on the CPAP and the display on the power pack read 37v. When I put the face mask on and the volt display didn't give any volts reading. The CPAP was still working so I went to sleep with 5 power bars on the display. Woke up 8 hours later, still showing 5 power bars with CPAP still working! Day 2, started with 5 power bars and did the same test again, same results again, only the power bank had 3 power bars showing! Day 3, same test, started with 3 power bars BUT 4 hours into my sleep the power bank shut down. The display showed 0 power bars. I then fully charged the power pack and performed the same test as above with the same results!!!! In conclusion, I was able to power my CPAP for approximately 20 hours on 1 charge!!!! O have to assume that others who left reviews stating that they only got 5 hours of run time from the power pack while using their CPAP, were probably using the Humidity or tube heater options on their CPAP which would explain the lower run time. Charge time was about 6 hours when plugged into my house 110v outlet. Haven't used the cigarette lighter power cord for 12v charging. This power pack looks like it will fulfill my needs while camping. I can recharge this power pack using the 12v cord while traveling from location to location. I will update when possible.

Used for a 63 quart cooler. Battery lasts 8-10 hours. Compact and works perfectly.

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

This little guy is perfect! The charge lasts quite awhile. Ideal for camping and short term needs. I have hooked up fan's phone's, radio's, lights. For the price it's a great find!

This product is worth it. I had a power outage and I was unable to use some lights and other sleeping devices that I needed for the household for my family. It worked like a champ. Lasted a long time was able to get a good night sleep. I use it to power other devices like portable Wi-Fi systems when I’m at kids baseball games. Well worth it I would definitely recommend it. However one downside is that it takes forever to charge. It’s not very fast so definitely an overnight charge. May be able to get a full charge.

Bought for those sometimes summer power outages in So Cal. Not for refrigerator as a gas powered generator would be needed for that, and if 24 hours w/out power "de GRUB" $ value would be hundreds less to replace than many $'s for a generator!! { then the gas and noise and cords etc etc.} No! For me it is all about OTA TV that this can power for many hours. A 32" TV {uses 35 wattts?} can be plugged in and run for maybe 12, to 15 hrs. My 19" {uses 10 watts} maybe 20 plus hrs. Already tested for 3+ hrs and works like a charm! Can run a 40 watt lamp {9 watt led} for matbe 25 hrs, and both TV and lamp can be plugged in and used at same time! But, splitting power! Have plenty of batteries for radios and small camping lamps, plus flashlights. So again... for me its about "watchin' de boob tube" with local TV stations via Rabbit Ears waiting for the power to come back on! I could read some Emerson by camp lights but I ain't 20 years old any longer:} Bon chance!

I bought this generator for dry camping to power my CPAP in the RV. I have only used it once so far and it failed slightly. I think it was my fault however so another test of its charging will be needed. I think i left it powered on after charging so it didn't last the whole night when the CPAP was plugged in. Again, my mistake. Charging takes a while. I'm still a newbie with the solar, so that no doubt contributed to the lack of sufficient charging. I started at 8am charging with the 60w solar panel and by about 6:30pm it had charged 60%. I was not watching it the whole time so it got shaded a couple of times. Not sure if that contributed to only charging 60%, but I will continue to attempt a better charge in the future. It does charge relatively quickly when plugged in. I got it at 20% and took less than 2 hours to fully charge.

This seems to be a great sturdy generator. I have only used it a couple of times but there are a couple of issues with it. I tried to run a string of Christmas lights at a craft fair. The generator kept shutting off after just an hour or so of use (I didn't really time it). The battery was still charged, it just decided to shut off for no reason. I had to keep turning the lights back on. I bought this mostly to run my cpap on a camping trip, or if the power goes out. It worked ok for 7 hours (thankfully it didn't shut off, but I may have to try it again). When camping, I don't sleep well anyway so I can deal with 7 hours It would be nice If it ran a bit longer. I haven't tried charging it from a solar panel yet. Now it's winter and we have less light I want to do that to see how it actually does. Overall it's easy to use and pretty self explanatory. The size is great I can place it under the table in our small truck bed camper and it doesn't take up any extra room. I just wish it would run longer at night.
