Mega 1 Power Station 3072Wh Kit (1024Wh + 1×2048Wh B2 Battery) – 2000W Output, 36min Fast Charge, LiFePO4 Home Backup Generator with UPS & Solar for Blackouts

3/5/2026 - updating review to 5 stars due to service from Oupes. They sent me a new one, hopefully this one lasts longer than the last one. 2/2026 - I purchased this in October 2025, two months later the mega 1 just wouldn't turn on. Contacted Oupes and they said they would send a replacement once I sent mine using a provided shipping label. Two weeks later I got a replacement. Fast forward to Feb 2026, and now the replacement has stopped working. It does charge the b2 battery, so I assume it's also charging it's internal battery just fine, but the screen and outputs are not working. Oupes is sending another one to me once I send this one back again. I don't know what the issues, is it that it can't handle solar directly, or can't charge and output simultaneously, or something entirely else. Oupes won't tell me. Will update once I get replacement again.

I have many power stations but this one is my favorite, I used it to power my refrigerator, a small chest freezer, and my furnace at the same time.

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.

This is perfect for our camper van, but I can use it in the house for power outages. This was the best deal during Prime day. It works great, I will get another B2 battery next Prime day. I like that the units can be separated, makes it easier to move around. Charges quickly and works for days when boondocking. A must have for camping, powers my induction cooktop, so I can use it when or where I can't have a fire or it's raining. It makes camping easy, and the large capacity lasts for days. My wife loves using her electric blanket with it too.
