  • Amazing Generator
This EnginStar 300W power station has become my reliable companion for camping, ballgames and outdoor activities.. It's lightweight and very versatile. We take it with us to power the iphone chargers and inflate air mattresses and rafts. All outdoor adventures would not be complete without it. I don't think we could do without it. I have run electronics like laptops and cameras without any issues. 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. I even ran a blender for on the beach smoothies. The battery will last 2-3 days with the occasional charge up of devices and the use of fans. We can power a fan all day if need be. It charges in about 7 hours and even will charge in your car or by solar. It even has a bright flashlight if need be. There is a convenient switch from AC to DC power as well as ports for USB and USB-C. Our family would be lost without this Enginstar Power Charger. We highly recommend it. And think it would be a great addition to any family! ... show more

  • Great buy!
Color: Green Grey
This is an awesome battery pack!!! I just got home from showing at our local 4h fair and I am truly impressed, for the money it is well worth it. It stayed charged 5 days and was well used for charging phones until I had to pull out the solar panels. I only gave 4 stars because it is slow charging with the solar panels but I expected that anyway! ... show more

  • Awesome portable battery
Color: Black
Like many others, I ordered this so I could use my cpap while camping and it works very well! One question I had prior to ordering, was how much noise it made, since my husband is a light sleeper. For anyone else wondering this same thing, it's pretty quiet. It does seem to cycle on and off, (maybe to cool it?) at which point there is a blowing type sound. My husband was not very happy at this point, but it doesn't last very long, so he was able to go sleep. Very happy with my purchase! ... show more

  • Super Lightweight and Great for Car Camping!
Color: Green
Great little generator!! So small and lightweight. Absolutely love that it just fits in any little space with all my other car-camping gear. Came over 1/2 charged out of the box. Took only about 3 hours to finish charging it up. Used it only to pump about a couple of river raft tubes and it was amazing! Didn't drain the power at all. Best little thing I purchased in a long time to make my camping life easier. Love the color too and got it at a great price!!! ... show more

  • Ok for phones not so much for laptops 😔
Color: Black
It'll last a couple days if you're charging small appliances only like cell phones or tablets but won't last long with laptops. Power station dies after about 2 to 3 hours charging a laptop so I'm gonna buy a v12 400w inverter instead

  • 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 ... show more

  • Decent for basic use, but has some limitations.
Color: Yellow
The power station works as advertised for charging phones, tablets, and other small devices, and it's fairly compact and easy to carry. However, the battery life wasn't as long as I expected when powering larger devices, and the charging speed could be better. It's a reasonable option for light camping or emergency backup, but if you need longer runtime or more power, you may want to consider a higher-capacity model. Overall, it's okay for the price but not outstanding. ... show more
