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

Great power source. Easy to charge.
Great plan B for power outages or road trips requiring charging phones and small appliances. Can be recharged in the wall outlet, solar or car charger. Time lasts according to how much is plugged in. Works well.

Amazing tool, Mobile Adjuster Approved!!!
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

Just what I needed
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.
