It's not weird behavior, it's a feature to save power, it charges earbuds and low power devices fine and cuts power when done. This doesn't have a ups switchover so idk why anyone would think this DC only (no AC plug) powerststion could be used that way.

And zero security is fake news. The button on the top left allows you to disable BT and save a little power. Similarly sized Ecoflow units don't have this capability.

I have this and think this form factor is ideal. No AC inverter makes it very efficient to top off electronics. I'll even use it to charge my larger AC powerbanks to give them longer runtime.

Quote from jongasse :
You can buy the "Hyper Tough 20V Power Inverter 150-Watt, 3-USB Ports" for $45 - $55 depending on which version Walmart has it in store any day and slap on a 21v battery. It's a fantastic piece of hardware and has PD, PPS - everything this has with the benefit that you can actually change the battery anytime. It's your choice what the battery will be.

Temu has the same Inverter for half the price. There are even cheaper and more powerful setups you can do for the same price. The current best is an EcoWorthy bundle that's 5x the capacity with a 1kW pure sinewave inverter for the same price.

The only reason to get this $100+ item is you don't have to do any of this work, it's all done for you and if the unit fails, either Anker or costco will, hopefully help.

Your example has a single usb c port with a 65 watt max input and output, no 12 volt out, and no solar charge port (xt60i). This thing has 4 usb c, with 2 having 140w output and 288 Wh of LiFePO4 batteries rated for thousands of charge cycles.

Can you show me some combination of parts in a list that can actually compete with this on price, even if a lot of them are generic? cause I buy a lot of this stuff individually and i cant
