It works and keeps working even in 90 degree temp
Color: Black
This is a great tool. It works and it is very versatile. I have a large portable fridge/freezer. 80qts (75 liters). It is plugged into my truck’s 120v inverter while I am driving. However when I stop and turn off the engine I lose the power to the fridge/freezer. So I plug it into the EnginStar power station and it keeps the fridge/freezer working. I tested it outside in Florida 90 deg heat and the EnginStar kept it working for 9 hours!!! Buying another to keep around the house!! ... 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

Works fantastic for the purpose I purchased it for!
Color: Green
I drive UBER about 12 hrs a day and I wanted to have a way to keep sandwiches and water cool and fresh here in the Arizona Desert Heat (sometimes over 110 degrees). So, I purchased a small 16 qt (VIVOR Car Refrigerator) cooler for my car that runs off of the cigarette lighter outlet in the back. However, when I turn off the ignition the cooler would turn off so I would have to unload everything overnight. My solution was to purchase this 300 W Portable Power Station to run the cooler and then when the ignition was on the unit would recharge. Over this weekend the unit kept the cooler running at 35 degrees for 24 hrs with the car sitting in the sun during the day and after 24 hrs it was still at that temp. The unit did finally go dead after about 32 hrs and the cooler was at 50 degrees but I am very happy and impressed with the unit. One of the favorite things about it is that it will charge while running the cooler, and it tells me the power going into the charger from the lighter plug (~ 34Watts) and the power being drawn by the cooler (~32Watts) so I can monitor where it is at along with the battery charged state. At the end of my day/night of driving it is completely charged and the cooler is ice cold. I would definitely buy it again, in fact I would buy 10 more if I hade a need for them. Very Happy Customer and would recommend it for anyone with similar needs. As a bonus I can monitor the temp from my phone as I am driving and adjust it if I so desire with the temp slide bar in the app. ... show more

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

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

Just what I needed
Color: Green Grey
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. ... show more

good so far
March 16, 2026 Update: Been using this power station on and off including with 100w solar panels ... still performing very well and no complaints so far. One item to note, it's not really built rugged and it will require a large weatherproof electric-box or equivalent, to use in an outside dusty, wet work environment, otherwise you run the risk of damaging it or worse shorting something on it since all ports are wide open. This dawned on me recently when I got caught in torrential rain while using it and had to rush it back to the truck and dry everything off carefully. ======================================================================================= This is the third brand I'm trying ahead of a planned semi-off-the-grid trip on a budget, and as a permanent UPS system (Uninterrupted Power Supply) replacement to ensure power continuity for my Internet service, sump pumps and various other sub 240w surge devices as part of my periodic swapping of current UPS devices which are no longer viable. As such I have purchased 3 of these 300w EnginStar units and as it turns out they are far more cost effective and powerful, then some of my most expensive UPS units NOT attached to my computers which now after many years require very expensive non-standard battery replacements (e.g. APC units NOT attached to my computers which can run from $113 to $320 per battery configuration). I also plan on taking a variety of other standard non-solar charging batteries on the trip, and I'll have the car lighter/battery connection as a last resort, but absolutely don't plan on actually using it as I've read too many horror stories where people run down or damage their car batteries and electric systems with all kinds of experimenting that doesn't make sense to me considering that the car battery is meant for a select and specific type of usage, recharging from your alternator, slow trickle with a controlled system or jump start when depleted and in a very controlled fashion. So far I'm cautiously optimistic that this unit may be the answer to what I'm looking for in a total sub $200 configuration including the solar panels for light duty work and ready standby UPS electricity availability. I will update more in a couple of weeks after I use it on a daily basis with various loads and under various scenarios. I'm evaluating this unit as compared to an: Apowking Portable Power Station 300W, Outdoor Solar Generator and an Anker Portable Power Station SOLIX C300 300w which was the most expensive of the three and my least likely to recommend for overall price/performance/design/outlets and inputs, or solar panels. Just so we all know I'm doing apples to apples, all are rated for 300w and about the same Wh give or take as follows: 220Wh for the Apowking; 288Wh for the Anker and 296Wh for this unit EnginStar Solar Generator. All have the option for solar charging; AC charging plug-in to outlet and DC charging via a cigarette lighter port from your car or equivalent. -On sale (Amazon flash) this EnginStar is the least expensive unit, the most power, best design and best overall performance and flexibility. -Right out of the box this unit had 2 bars of standby charge and funny enough so did the other two units - exactly 2 bars. -Design wise, this unit far outperforms the other two for what you'd reasonably expect in types and numbers of outputs and inputs. In fact, you would have to combine both the other 2 units to get most of what you get on this one unit and you may still be missing some. -Of specific note, this unit has the very best display with the most comprehensive information and built in intelligence on data that you actually need to know about and monitor in the field. It doesn't require any ancillary app or connectivity complications to your phone like the Anker which also doesn't give you the full spectrum of data that this unit displays. The Apowking was better than Anker, but still nowhere near this EnginStar. -This unit will show you which connections are getting what power both input and output, and you can adjust what devices you hook up accordingly to maximize what you need fastest which makes it very clever and useful. -This unit comes with a power attachment which looks like a laptop power unit (2 pieces) and delivers a strong 59W input making recharging via AC a breeze. It also has a cigarette lighter attachment which of course will be limited to output from your car and which I didn't test at all. It compares well with the Apowking which has a similar set of attachments but charges much, much slower on AC and also with the Anker which I found actually charged relatively fast, but was lacking ANY attachments other than for the solar panel and a lone USB-C cable. Very strange that it's advertised as an off the grid unit when it doesn't even include a basic POWER BRICK which you have to pay a lot more for because of the power requirement. -This unit allows passthrough charging, meaning it allows you to hook up your outputs and use them/charge them while you're plugged into an outlet making it very clever and convenient that you don't have to que up stuff while the unit charges. The Apowking had a similar feature albeit much less power in and out. The Anker was glitchy at best and downright unreliable at worst, as it frequently freaked out with full outputs loaded and plugged in -- yet another reason not to recommend it. -I tried three versions of solar panels, Anker 60w, Apowking 60w mono-crystalline and Voominhtec 100w mono-crystalline. Of specific note - the Anker supplied solar panels ABSOLUTELY DID NOT charge at all unless in full blown sunlight therefore I can't recommend them - they had not even a trickle of power in just plain daylight, or when exposed to other sources of light. The Apowking and Voominhtec both performed with limited sunlight and other sources of light. Of course the output was lessened accordingly, but still charged as long as there was sufficient daylight or other sources of light. -I performed separate tests over 3 days with the solar panels to make sure I had repeatable test scores (approximations) for each unit. As expected the 100w charged quicker across all units, but both of the 60w panels in the other brands also performed very well with the specific note that the Anker requires full blown sunlight or it will simply not work at all. Price wise the Apowking 60w and the Vominhtec 100w were extremely competitive and have a nice on panel direct connections for USB-A and USB-C that did an awesome fast double duty without any problems with additional devices connected in addition to the power station. The Anker has more convoluted connection and no additional output for anything except the power station. The Anker panels are also much more expensive without any notable differences in build, power, or convenience and the pitfall of only working in direct sunlight - for this reason once again I can't recommend the panels at all. -Of the three units, only EnginStar and Apowking can perform well as a UPS replacement primarily because of the 2 prong/3 prong outlets they have readily designed into the units and also because both can provide uninterrupted passthrough power even when there is an electric outage without blinking (i.e. doesn't need to switch off and on like other UPS units) therefore my devices don't reset or lose power unexpectedly - these make them a multi use device in my configuration and extremely flexible traveling, around the house and around the yard without needing to run extension cords to various locations at the pool, gazebo or shed. That's it for now ... more to follow in a week or two ... ... show more

This is a great little portable power station. Bought for power outages and camping with my CPAP machine. 5 hours to charge, ran CPAP with full humidity on and it lasted 7.5 hours. Next test I took humidity setting to 2 and it used slightly more than half power. Probably good for 3 days with humidity turned off. Only negative and thus less one star the lights showing hare status and us are very bright and they cannot be dimmed. I had to buy 80% light blocking stickers now it’s readable and doesn’t light up the whole room. ... show more
