Mega 1 Portable Power Station 2000W (Surge 4500W), 1024Wh LiFePO4 Battery Generator, Expandable to 5kWh, UPS, for Home Backup Power, Camping, Road Trips

This power station is impressive. It has plenty of power to run multiple devices and works great for emergencies, travel, or outdoor use. The build quality feels solid, and it’s easy to use with clear controls. Charging is efficient, and the battery lasts a long time. Definitely worth the investment!

This was a great purchase. The OUPES Mega 1 has been very useful and performs really well. It has plenty of power for different devices, and I like that it can handle higher-demand items without issues. The battery life is solid, and it feels reliable during use, which gives peace of mind, especially during outages or when traveling. It’s also fairly easy to set up and use, even if you’re not very technical. Overall, I’m very happy with it and would definitely recommend it for anyone needing a strong portable power source.

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.

The OUPES Mega 1 Portable Power Station 2000W is a powerful and reliable energy solution, ideal for emergencies, camping, or home backup. With its strong 2000W output and 1024Wh capacity, it can easily run most essential devices. It features fast charging, multiple output ports, and a durable long-life battery, making it both practical and efficient. Overall, it’s a great choice for anyone needing dependable portable power.

Well pleased with this power station, best price in this size range. Solidly built, weight is light enough most should be able to pickup and move around. Battery life is as expected for this size range. The display is easily visible in most conditions and blanks after a period of time. The only minor complaint that I have is the door for the bay with the input ports can be a little hard to open, having to pry it a little with a pointed implement as my finger nails are not that strong. I am currently using it in EPS mode. The app was easy to connect to the unit once downloaded providing basic information on the various states, have not explored it alot at this time.Overall I would highly recommend this unit, plenty of lifting power at 4500 watts surge and 2000 watts running with 1024 ah of battery.

only had it for a few months but so far so good, works well and charges quickly

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.

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.

I have it only for a few weeks, it's a helpful thing, reliable, delivering the power i need for my induction cooktop 🍳 and Airfryer an the road in the truck 🚚 i like it 👍👍👍

Très bon service après vente

Works great but loud fans when charging up fast

cette batterie est totalement inutile . se décharge trop rapidement. très bruyante prend beaucoup de place . je peu pratiquement pas m'en servir
