OUPES Mega 2 2500W Portable Power Station with 2048Wh Extra B2 Battery, Up to 4096Wh Lifepo4 Home Battery Backup with Expandable Capacity, Solar Generator for Home Use, Blackout, Camping, RV

When turned off will not turn back on by switch. Updated oupes replace the unit. Thanks you oupes.

This is an extremely useful product that is very price competitive. We use it to power our camper via the 30 AMP outlet. It's like having an RV park electrical pedestal with us at all times. Awesome!!

I will start by stating I like the overall functions of the unit. It performs well as a power station. You can watch numerous YouTube videos of the pros for this unit.However, my primary use is for solar charging. This unit fails terribly. Oupes uses a low quality mppt charge controller. This results in bad solar performance. It takes 5 to 10 minutes to get to full charging rate. The second any clouds or changes in sun occur, the unit "resets" and begins to start the charge cycle from 0 watts. The 5 to 10 minute ramp up to full charging rate begins again. This continually occurs during the charge cycle. Therefore, solar charging is incredibly inefficient and does not capture all available sun light.This unit will probably work well during full sun and cloudless days. Otherwise, look elsewhere for a unit that will primarily charge by solar.

Got my Mega 2 just before Christmas and solar panel a few days later.Have done a quick checking with solar panel and AC charging. It charge well with each of the two methods, the noise is low and the response is good. Both product seems to be well built and well thought out. MC4 to various adapters are provided and come in handy. Cable seems to be thick and good. Overall, my impression is good and glad that I decided on this brand. Mega 2 for me is a "multi-use generator" where I can use it for camping and at home as well. This is the main reason I choose Mega 2. If you are concern about the weight, you could use a light duty hand truck to carry it to your vehicle and just lift it. It is more liftable than Mega 3 for sure even though Mega 3 has wheels.

I like that the price of LiFePo batteries is dropping. Hoping for the next generation. I use this for camping and just toying around. Love that it comes with various connector types that make it easy to combine with other panels or powering sources. Charges VERY fast if you can provide all the wattage. So far it looks good. Ran my Macbook Pro for 20 /- hours, can run a small seed starter indoor light for about 14-16 hours.Over all I am happy with it, support was excellent which is a huge factor when dealing with anything this pricey. The original order went someone where else or they ran out. Anyhow they recommended this and offered additional discount on top of Amazon Prime specials.
