    • Outstanding Power Station – Reliable, Fast Charging, and Built to Last!
Style: Mega 1+100W Panel
I’m extremely happy with this solar generator! The shipping was fast, and everything arrived in perfect condition with secure packaging. Setup was simple and straightforward — I had it running within minutes. The build quality is excellent; it feels sturdy and durable, with a solid design that inspires confidence. The performance is impressive — it powers all my devices and small appliances effortlessly, and the LiFePO4 battery gives me peace of mind knowing it’s long-lasting and safe. The 100W solar panel charges efficiently, even on cloudy days, and the app control feature is a great bonus for monitoring everything in real time. This has become my go-to for camping trips and home backup power. It’s quiet, reliable, and holds a charge for a long time. If you’re looking for a high-quality, dependable power station, this OUPES Mega 1 is absolutely worth it! ... show more

This solar generator is very convenient. With a high power of 2000W, it can supply power to many electronic products in my home without worrying about not being powerful enough. The AC charging is very fast. I like it very much.

    • Well made. Great features.
Style: Mega 1+100W Panel
Well made. Very impressive for what you get. When purchased, I was only thinking about mobile power tool use and bringing power out to a shed (lighting, music, fixing items). But realized the advantage will have during/after hurricanes.
