It really is powerful. But no, you can't charge a 288wh battery bank at 140w, or even 100w, as sustained output of this device, de-rates and overheats it. It's built well, but as an example, I can't fully charge my anker solix C300. Theoretically, it should charge at 250w using both 140w outputs. reality is. it stops around 40%..... because heat. Same at 100w. Sooooo I consider this device a miss, depending on your needed use case. I don't suspect it's that efficient, if that also matters to you.also, wifi stuff? no clue why, and I don't like that I can't just turn that off.This should have been a home run. But it isn't, in my book. I did however still keep it.

I'm thrilled with this charger. It's incredibly powerful, and charges all of my families devices at once really quickly. Its extensive features also help me to maintain the health of our batteries. Highly recommended.

Good hardware, terrible configuration options. I should not need an app to configure my charging brick, and even worse need to connect it to the internet on top of that. Really a step towards to the dark ages instead of a step forward for Anker.

Multiple C outs (4) and A outs (2) provide a variety of options for charging devices.

Nicely made - and HEAVY and stays in place. Instrumentation is interesting in a geeky way (i.e. particulars of each item charging). BUT... even if THE charging hub for ALL your stuff, it's a lot of $$$. Clock display is small and hard to read. Wifi connection drops frequently (although you don't need wifi day-to-day). App is crazy detailed but again just if you have a geeky fascination with charging dynamics.
