The DELTA 2 Max has completely changed the way I prepare for power outages and road trips. I’ve tested a lot of portable power stations, but this one delivers on every promise. The speed alone is impressive—going from 0% to 80% in under an hour (just 43 minutes with solar + AC) feels like a game-changer. No more waiting half a day for a usable charge.
The 10-year LFP battery life is what sold me. I use it weekly, and knowing it’s rated for 3000 cycles gives me confidence I won’t be replacing it anytime soon. It feels like a serious long-term investment.

This thing powers everything—fridge, microwave, air fryer, even my power tools—without breaking a sweat. And with 15 outlets, I never feel like I’m sacrificing one device for another. It’s more than a backup—it’s a whole-home solution in a box with up to 2400W.
You can also get the optional solar combo, which is great in case you have an emergency outage this winter.
Despite all that power, it’s surprisingly quiet, making it ideal for overnight indoor use.
