Very much over the limit. The Limit is usually 25500 to 27000 mah depending on the voltage of the cells used aka 3.7 or 3.8 volts, etc.

This is a 148 watt hour device (48 watts hour over the 100 watt hour limit) and it has a 3.7v voltage (actually 4 x 10,000 mah batteries together in a series per the bottom of the device in the customer review pictures)
I have this power bank and it does pack a wallop of a charge. Be aware, this is NOT a small power bank but worth its size. I bought this AC outlet charger to keep it charged up. If you use a low-power AC outlet charger, it will take well overnight to charge this power bank up.
If you have a steam deck, you want 45w output. Good deal otherwise, but yeah, might get the attention of the TSA.

I am guessing this is technically over the TSA limit? YMMV on ever getting stopped, but i think technically you need airline permission for battery banks this big

It's almost embarrassing to click on all the links and Amazon says, "Last bought....."

With the deals on both, total was a little over $130. New toys for my laptop bag.

One of the reviews for this thing mentions that the port to charge this is the same as the port that it uses to send charge out. Is that accurate? Is that normal/safe?

is this allowed on a plane?
If you pay attention and read you would know. Don't comment if you're not willing to read. It was literally the very first comment.

Answer is NO. 26800mah is the highest approved.

Thank you for your comments, I did read that, but rules change all the time. Im reading in some places it might be allowed as long as it's a carry-on, but I don't know. There is always a grey area with all these rules. I wanted to hear if anyone here got it taken away at the airport, that's all.

Your question was a bit broad which made it sound like you didn't bother trying lol.

Anywho, time it takes to recharge this mammoth?
