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! Review: Works fantastic for the purpose I purchased it for! - 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. ## Features - PORTABLE BUT POWERFUL: EnginStar Portable Power Station with ETL Certification, and the portable size of 9 x 5.5 x 7.5 inches, weights only 6.5 pounds, but armed with 296wh capacity and 300W AC output, EnginStar portable power station can provide enough juice to charge your phones, laptop, camera, cpap, drone, etc. Designed with 8 output ports can charge several devices at the same time, which make it a perfect emergency battery, outdoor and camping backup battery - 110V PURE SINE WAVE & MULTIPORT: Built with two 110V pure sine wave AC outlets to make sure the solar generator (solar panel not included) works quieter, more efficient and more stable, which can protect your sensitive devices from damage such as laptop. 2 Regulated DC outputs (12V/24V) can provide a stable power output for DC appliances such as mini-fridge or car vacuum cleaner.

Started changing it immediately, after about 20 minutes it stopped charging, wouldn’t turn on or finish charging. Just got a dud, I guess. Maybe the ones that work do. **Q: Can it charge my gateway Xfinity router? How long?** A: It depends on the wattage. It is 296 watt hours. It can power a fridge that I have that is about 60 watts for about 5 hours on a full charge. It has a limit of 300 watts but I think the surge wattage is about 450. Hope that helps. I really like it! **Q: Can i order another 110 vac charger? Lost original** A: Dear Customer, please contact our after sale support mailbox: support@enginstar.com, we will arrange a replacement charger for you **Q: anyone use this for a small music PA set up?** A: Yes. I use a Yamaha Stagepas 600 and it seems to be okay for a solo gig. Beware that when you plug multiple inputs (other than a mic and an instrument) into your PA system, you might experience times when the battery shuts off momentarily. I'm considering switching to a unit with higher wattage. Best of luck on your choice. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing Generator *by B***T on July 23, 2026* This EnginStar 300W power station has become my reliable companion for camping, ballgames and outdoor activities..

Whether I’m camping, road tripping, or facing a power outage, this device provides reliable and consistent power for all my essentials. Key Features I Loved: Power Capacity: The battery size is more than enough to charge my phone multiple times, keep my laptop running, and even power small appliances like a mini-fridge. It has a solid capacity, and I never worry about running out of juice. Also I used it for my husband's Cpap machine! Lasted for 3 days! Multiple Outputs: It offers a variety of output ports, including USB, AC, and DC options, allowing me to charge multiple devices simultaneously. The addition of a fast-charging port is a great bonus. Compact & Lightweight: Despite its impressive power, the unit is surprisingly compact and lightweight. It’s easy to carry around and fits nicely in my car or backpack without taking up too much space. Durable Build: The design is rugged, and it feels sturdy. I’ve taken it on a few trips now, and it has held up well to the elements, including a bit of rain and rough handling. Solar Charging Compatibility: I love that it’s compatible with solar panels (sold separately). It’s great for long camping trips or emergencies when there’s no access to an outlet. Areas for Improvement: The only minor downside is that it takes a bit of time to recharge fully if you’re using a standard wall outlet, but this is typical for larger capacity units. The solar recharge is a fantastic option but depends on sunlight availability. Overall Verdict: This portable power station is a fantastic investment for anyone who needs reliable power on the go. It’s versatile, well-designed, and offers great peace of mind, whether you’re off the grid or just need a reliable backup power source. Highly recommend! ## Frequently Bought Together - 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 - ENGINSTAR 60W Foldable Solar Panel Charger with 18V DC Outlet for Portable Power Stations EnginStar/Jackery/Rockpals/Flashfish, Portable Solar Generator with QC 3.0 for Outdoor Camping Van RV Trip - EnginStar Carrying Case Storage box Travel Business Lunch Bag Shockproof Universal Compatible for Jackery Portable Power Station, picnic camping wild fishing hunting - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/535120032-enginstar-portable-power-station-300w-296wh-solar-generator](https://www.desertcart.jp/products/535120032-enginstar-portable-power-station-300w-296wh-solar-generator) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-31*
