Fast charge, but a bit loud
Charging in under an hour to 80% is great, especially when combining solar and generator. However, when it's under heavy load, the cooling fans can get quite loud, which is noticeable in a quiet room.

I bought the DELTA 3 Ultra Plus with 2 x 400W Solar Panel bundle to power my tools for off-grid DIY projects. The 3600W output is more than enough for saws and drills. The charging from solar is efficient. It’s heavy to move between project sites, but the performance balances that out.
It has many ports, but some of the USB ports are a bit finicky and don't always connect immediately. For such a robust unit, I expected more reliable port functionality.
While powerful, this unit is simply too heavy and bulky for frequent transport.
This power station has incredible power output for its size.
