Set name: Mega 1
I received this battery in good order, well packaged, and in new condition. It didn't take long to arrive but it was shipped from my home state so it didn't have to travel far. Unboxing it, I found three power cables and a service manual. The manual is not very detailed and the English is sketchy so I'm assuming it was printed using a translation program. When I got it out of the box, read the manual, and turned it on, it had about 60% battery so I charged it on low input (there is a high input and low input). It charged quickly and came to 100%. I tried it to see how long the battery power would last. I gave it a draw of about 120-130 watts of power and it lasted almost 9 hours. Pretty impressive for the first run. When it was out of power, it gave an error code. I turned the unit off, then back on, and then plugged it in and it charged to 100% again without any problems. So far, this seems to be a reasonably good backup power supply. If you're using it for emergencies or for camping, outdoor activities, I think it would be good. However, if you're looking for something to keep you off grid or for everyday use, this is probably too lightweight with not enough KWH to do that. It is much lighter than I thought it would be. It's easy to move around, portable, but the plastic isn't really top quality. I wouldn't expect this to take a hard fall or nocking around too much. I seriously doubt it is water or weather, resistant. I haven't tried to use it as a UPS but the manual does say you can do that. There are two different settings for charging the unit, (high and low). It's a little complicated to change that setting but if you have a lower amp circuit and need to charge the unit without blowing a fuse or tripping a breaker, it can be helpful. It switches the input from about 1200 watts to around 600 watts but it takes longer to charge on lower power. My only gripe is that at low or high input the fan runs while it is charging... always runs while it is charging... the fan on low power charge isn't very strong or loud, but it is there, for two hours or more... so... it can get annoying. At some point I'll try some more features of this unit and add to this review, but for now, I'd say it's a good product and will do what I need.

Set name: Mega 1
This unit packs a powerful punch for the price and is very versatile. The Mega 1 is the smallest and lowest power unit in the series, but that doesn’t mean it isn’t a useful power backup or supplement. I ordered one on a friend’s recommendation, and I am happy with my purchase. The case is a sturdy, durable unit, heavy, but not to heavy to lift using the attached handles. Setup is easy, and the included cables are easy to connect. The recommendation is to fully drain the battery before the first full charge to balance the battery management system. I did that, , plugged it in, and it charged quickly. There is even a rapid charging option. I got hooked and bought a separate solar panel, and am able to easily charge in on sunny days using the included cable. The design layout on the front panel is done well providing access to usb, AC and DC port options. The app was a bit clunky, but there have been many updates to it in recent months. You can use the app to monitor and control the station, though you can also use the station totally offline without the app. I would like to see the brightness of the front screen being a little brighter in order to more easily read. Overall, I’m very happy with the Mega 1. I did research, and comparable units are much more expensive. The Mega 1 is now selling for even less than what I paid.

Reliable Power When You Need It – OUPES Mega 1 Review I purchased the OUPES Mega 1 Portable Power Station last month, and it has already proven to be one of the most reliable and user-friendly power stations I’ve used. With its 2000W continuous output (4500W peak) and 1024Wh LiFePO4 battery, it delivers dependable power for a variety of needs—from home backup during outages to powering devices while camping or using it with an RV. ✅ Key Highlights from My Experience: Easy Setup: Right out of the box, the setup was quick and intuitive. The user interface is simple and clear, and getting it running took only a few minutes. Solid Build & Expandable: The unit feels well-built and is expandable up to 5120Wh, which gives peace of mind for longer trips or extended outages. Solar Charging Compatibility: I’ve tested it with solar panels, and the 800W solar input is impressive. It’s compatible with standard MC4 solar connectors, making integration smooth with my existing gear. Fast AC Charging: The 1400W AC input recharges the battery quickly, which is a great feature if you need to top up the unit between uses. ⚠️ Minor Issue: The only hiccup I’ve encountered is with the Wi-Fi connectivity via the app. It struggles to connect consistently over Wi-Fi. However, Bluetooth works reliably, so I’ve been able to monitor and control the system effectively using that method. Final Thoughts: Overall, I’m very pleased with the OUPES Mega 1. It offers an excellent balance of power capacity, ease of use, and expandability, making it a smart investment for emergency preparedness and outdoor adventures. If OUPES improves the Wi-Fi functionality in a future firmware or app update, this would be a near-perfect solution for portable energy needs. Highly recommended for anyone looking for a powerful, solar-ready, and user-friendly power station.

The OUPES Mega 1 is kind of a no-brainer if you actually look at what it delivers for the price. It’s got a 1024Wh LiFePO4 battery (3,500+ cycles), a 2000W inverter with 4500W surge, UPS mode, app control, and solar expansion. Basically, everything the high-end brands brag about—just without the inflated price tag. Yeah, it’s a little heavy at around 30 pounds, but I only use it for truck camping and shoots, so it’s fine. It sits behind the seat or in the bed and doesn’t move much anyway. The handles make it easy enough to haul when needed. Battery life’s solid—I can run my fridge, laptop, drone chargers, lights, and espresso maker for days, then plug into solar and keep it going. It charges stupid fast too—about 80% in an hour if I need to top off between drives. Once I add the solar panels, I’ll basically have unlimited power wherever I park. Design-wise, it’s clean and functional. The display’s bright, ports are actually where you want them, and the build feels premium without being overdesigned. For me, it hits both worlds: power for long video shoots (charging cameras, lights, and editing gear) and comfort for overlanding (running camp lights, Starlink, and the fridge). I’ve used plenty of overpriced power stations, and this one just makes sense. Can’t wait to get the solar setup dialed in—it’s about to make my truck a full-on mobile studio.

Set name: Mega 1 +B2 Battery
What an incredible power backup system. I've been using it to run my Dometic Fridge and other goodies camping. The battery backup outside of main unit will run my fridge for over a week. Really impressed with how simple and intuitive this battery system is. The cool part in my scenario is running the fridge directly from the 2000W backup battery - it has the DC car plug! When cross shopping i didn't see other systems that had this option. My buddy runs a top competitor that is a bit more expensive for the same type of setup; he finds my system a much better value and was a bit jealous that you can run things off the backup battery. The main battery must be used to charge the backup battery is the only caveat. So they can't be apart for too long. It is the perfect camping setup for my week long trips to the beach. The cords, plugs and buttons are all really beefy. It feels like a solid unit overall. The connecting plug between batteries is massive! I tested 400W of solar input and it charged the main battery in a couple hrs. Faster than either of us expected as we were only getting 250W total from panels/sun. The system picked up the charge right away. I researched whether a charge controller that i have would be needed. After some research it is recommended to NOT use a solar charge controller as the main unit already has it built in. Just an FYI. House charger got everything topped off quickly. You will see the charge on batteries as they are charging together. It has checked all the boxes. I don't have any complaints. I got it on a Prime Day special. The next day it was $400 more! I got lucky b/c this system has exceeded my expectations.

I really like this little power station, especially at the heavily discounted sale price available when I purchased, and the excellent sales service. The sale price on Amazon was considerably higher than the sale price on the Oupes website; I discovered this after my purchase, but when I contacted them they refunded me the difference by the next day. Awesome sales service! Mine purchase was scheduled for delivery in 9 days, but it arrived in 3! Note that this product is NOT RETURNABLE through Amazon. The power station is compact and lightweight, perfect for my camping needs; it delivers enough power to run a small heater, electric blanket, electric hotplate, run lights, charge electronics, etc. However mine did NOT have the advertised surge capacity (details below). Charging speed is excellent: full charge from a wall AC outlet on high setting took <45 minutes (I wasn't standing by when it topped off) and on the battery-friendly slow charge rate took 91 minutes from 0 to 100%. Manufacturer recommended practice is to leave it charging after it reaches 100% until the fans kick off; for me this took another 24 minutes. The manual says do not charge from a non-pure-sine wave source, so if you use a generator, only use an inverter generator. I have not tested solar charging. The only negatives I found are: 1. the advertised 4500w surge rating is grossly optimistic; mine consistently trips between 2050-2200w. I've contacted the manufacturer to inquire if this is a defect or just bad advertising; to be honest I didn't expect (or need) that much surge capacity. 2. the CleanEnergy bluetooth app is really basic, providing a only couple of simple configuration settings and wireless control, but no info on the state of the cells, temperature, or such. Overall I'm glad I purchased this power station and can't wait to get it into the field. If I figure out why the surge capacity is so low and get it fixed, I'll upgrade the product rating to 5++ stars. Even without the extra surge capacity, if you get one on a deep discount sale it is a 5 star value. I would buy it again.

Works great but I didn’t know it would come in two packages. I called on Sunday and they got back to me the next day. No problem. Fast charge with shore power; slow charge with the single solar panel. Works great for camping.

After five months of using this power station in a variety of locations, scenarios, and countries, I can say with full confidence that this unit performs on par with other more well-known or premium brands, but at a significantly more competitive price. Over these five months, the unit has provided us with the energy we needed during the expeditions carried out with our camping club, ranging from Denali and Sequoia National Parks, as well as BLM camping sites in the Cargo Muchacho Mountains in the United States (where we explored old mining settlements) to visits to archaeological sites in Baja, Mexico (Cataviña and the rock paintings in the Sierra de San Francisco), and Yaxhá National Park in Guatemala. We used this power station to charge mobile devices and power small electric coolers, but primarily to keep our Starlink satellite internet system running at our base camp. The unit was recharged using generic 200-watt solar panels, which under clear-sky conditions charged the unit in an average of approximately six hours, a performance I consider very acceptable for an entry-level power station. Additionally, I have used this unit on two occasions during power outages in the area where we live. During interruptions lasting a couple of hours (common in certain semi-rural and rural areas of California) the power station was able to keep a full-size refrigerator running, along with our internet modem, both operating simultaneously without any issues. Overall, to this date, this unit has not only met but exceeded my expectations, and I can confidently recommend it.
