5.0 out of 5 stars Works to power our smoker!
Reviewed in the United States on February 12, 2024
My initial reasoning for this battery was to power my Traeger pellet grill / smoker. I was gifted the smoker a few years ago but we found we don't have any outlets outdoors. We would have to run an extension cord out the slider door into the kitchen for a few hours, so naturally we hadn't used it. I couldn't find any reviews that would suggest this battery would work for us, so I figured I'd write out my findings and hopefully it'll help out someone in a similar situation.

I read that the smoker uses about 300W for 4 minutes, then 50W after that. The page for this battery shows it can handle 300W, but I read further in the user manual and found that the AC ports only support 200W and would power off if they exceed that.
In powering on the smoker, the display showed it was pulling 257W initially and about 45W after a few minutes. I ran it for about 40 minutes as a test and the battery finished with 85% remaining.

This past Sunday I smoked some turkey sausages for 2 hours (plus 20 minutes for preheat and shutdown cycle) and the battery had 45% remaining at the end. The display said it could have kept going for about 2.5 hours. It lasts long enough for our uses (sausage, burgers, hot dogs, chicken), but for something like a brisket or ribs it probably won't last long enough.

5.0 out of 5 stars Every thing I need
Reviewed in the United States on September 6, 2022
I read the reviews on this, and yes, it does have some minor flaws, but none of these deterred me from buying. It has two AC outlets but only one can be a three-prong grounded cord. I have an adapter with three outlet plugs: problem solved. The USB-C connector is PD3 compliant, so my phone charges rapidly. The description of the Power Saving mode is not complete. Here is the response from Customer Service:

"For your information first: The power saving mode is mainly for the AC outlets and the car socket. It will not control the USB ports.
The AC outlets on the 521 Powerhouse will turn off automatically in power-saving mode when the output from the AC port is continuously less than 10W within an hour. So the threshold for "lower power" is less than 10W."

I like the display which shows power input or output in watts, the percentage of battery remaining, and the time to charge/discharge.

I bought this unit based on Anker's reputation and my satisfaction with many of its other products. My primary use will be to power my fiber gateway during power outages (a recent three-day outage prompted my purchase), but I'm sure it will be used often for other portable power needs.
