The PowerHouse II 400 has all the ports you might need, including several USB ports, a 300 watt AC inverter, and a DC-out port for car accessories.
Most importantly, the battery includes a USB-C PD port, meaning that you can charge your laptop or smartphone directly, without having to use the inefficient AC inverter.
Charging your laptop with the AC adapter may be inefficient, but having the options is critical. With a 300 watt inverter, you can (separately) power a fridge, air purifier, or a CPAP machine with ease.
There was really only one major pitfall that I could find with the PowerHouse II. It's a small complaint, but Anker's website says that you can charge the battery at 120 watts by using the wall adapter and a USB-C charger simultaneously, but I wasn't able to make this work.
It sounds like a nitpick, and it is, but when you're waiting for a battery this large to charge, you'll appreciate any way to pick up the pace.
When choosing one of these generators, you really need to figure out what your needs are.
For a compact battery like the PowerHouse II 400, the use cases are pretty varied; you could take it to a picnic with ease, or you could leave it charged in your apartment for backup power. And after the wildfires on the west coast earlier this year, I certainly enjoy having a couple of hours of real power standing by.
