I’ve been looking at that one, or thepopsockets popgrip magsafe but haven’t decided yet Please update if you’ve bought the magGo!
It's the official popsocket grip for magsafe. I have yet to run into an issue where it disconnected when I didn't want it to. I have to make an effort to remove it, and would guess it's roughly as strong as the one you posted.
Never tested with a drop though. Pretty sure you can stop by your local target or best buy and test it out to be sure.
Also have one of these and it sticks on very strongly https://www.amazon.com/dp/B098DWZ4Z9/ref=cm_sw_r_apan_glt_i_J8QPFZXNHV55YNMB765A?_encoding=UTF8&psc=1

There are tons of magsafe accessories available. Almost all will say for iPhone because magsafe is an Apple term an not officially available for android.

I have been using the Peak Design case, Popsocket, and a Magsafe car mount for over a year with my P6P. I also charge every night on the Pixel Stand 2. Just keep the case on and pop off any magsafe accessories.
