Portable Power Station EnginStar 300W Solar Generator 110V 296Wh Power Bank Two Pure Sine Wave AC Outlet 80000mAh Lithium Battery Pack for Camping Outdoors Trip RV Hunting Vans Emergency Backup

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.

I order from Amazon all the time, but almost never write product reviews. But I felt the need to write a review after having this machine for a little more than a month. I did quite a bit of research before purchasing this. Over the course of a few weeks, I probably looked at somewhere around 100 of these. I had very specific requirements when it came to what I needed this for. This has exceeded my expectations and then some. It takes a little while to charge. I haven’t tried it with solar panels but I have use the cigarette lighter charger and the wall charger. It comes with both of those cables it does not come with solar panels just to be clear.you have to buy those separately. But I must say I use a hair straightener with it. As well as various other devices. I like how you can see in real time exactly what the wattage being used is of each device like on my straightener it tells me in real time what why did just being used. It shows the surge when you first turn it on and it starts heating up. And then immediately starts to fall down to the 25 walks that it says on the straightener. I can use my hair straightener. Can it can charge my phone and my car vacuum and the battery only goes down like a bar. You can use it while it’s charging as long as the wattage that you’re trying to output is less than the wattage that is being taken in. Meaning it will tell you how many watts is going into charge it which is about 60 so as long as you are using less than that, it will charge as you’re using it which was one of my requirements actually when I was looking at these things. I could go on and on about the different features but all in all I’ve been using this for about a month now almost daily and I must say I am so glad I bought it each time I use it I know I made the right choice. It is only 300 W so you’re looking for something to power a lot of stuff this isn’t the thing for you but on a day-to-day basis to do the things that I needed to do it does effortlessly I hit a home run with this little machine.

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

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 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.
