Be sure to check out my video review in the video section above!If you’re shopping for one of these you’re going to find another one called the “Powerhouse 100.” I think the “90” is the new version of this product with a slightly smaller battery. This may have been required so it can be under the minimum for airline carry-ons, or they were looking so shave some cost. The difference between the two is about 10 watt hours.The Powerhouse 90 advertises about 87 watt hours – meaning if you had a 1 watt draw it could run (theoretically) for 87 hours. The real-world longevity you’ll get out of the battery will vary but I think if you had a full load of 87 watts through its AC outlet you’ll likely see far less than an hour due to overhead of the inverter, etc.The powerbank can deliver a maximum of about 160 watts simultaneously budgeted as follows: 12 watts for the USB-A ports, 45 watts for the USB-C port and 100 watts for the AC outlet. In my testing I plugged in a large video LED light that draws 36 watts via the AC outlet, had a Steam Deck drawing about 33 watts out of the USB-C, and plugged in two smart phones to the USB-A ports. It was able to provide consistent power to each device.The power bank charges via the USB-C port at a rate of 45 watts. A full charge from empty will take about 3 hours via a 45 watt USB-C power adapter.So what’s the use case here? For me it’s about charging the devices I have in my production bag that can’t charge over USB. For example my Canon and Sony camcorders I use for remote productions need to be charged using their AC adapters. This pack will allow me to keep things topped off (or even fully powered) as we walk from one location to another when shooting a dispatch video.I've already deployed this several times in the field and it has been flawless. A great device that travels with me everywhere I need some added backup power at the ready.
