★★★★☆
Fast charging is a plus
The rapid recharge rate is a definite advantage, especially when preparing for unexpected outages. It's been very dependable so far. I just wish the accessory port options were a bit more varied.

Customer reviews
What customers say: Powerful output, fast charging, and robust build quality are praised. Its considerable weight and size are noted as potential drawbacks for portability.
★★★★☆
Charges quickly, a bit pricey
The 89-minute charge time from wall power is really convenient. It feels solidly built and handles multiple appliances well. My only minor gripe is the cost, but for the features, it's generally good.
★★★☆☆
Great features, but heavy
The power output and battery capacity are exactly what I needed for my workshop. Running power tools with the X-Boost feature works well. However, moving the 70.5 lbs power station around is a significant workout, and I wish it had wheels or a built-in trolley system like some others. It’s a good product if it stays put, but not very portable.
★★★★☆
Good power, a bit heavy
This power station delivers on its promise for powering appliances, even using the X-Boost for my electric kettle. The 3072Wh capacity with the 400W solar panel setup keeps things going for a good while. However, at 70.5 lbs, it's quite a haul to move around, even with the handles. If you plan on frequent relocation, consider its weight.
★★★★★
Powers our whole setup
Bought the DELTA 3 Ultra with 2 x 400W Solar Panel and it powers everything we need.
