magbound try out

I have been lurking for a long time, not a lot of interesting things happened in my life.
As I like some pain creeping in, I try hogties,... Thing is, I'm frustrated I have to have release mechanism because of my soloplay. When I'm too bored, I'll escape, seems I just can't help myself 😟
Some time ago, while browsing etsy I came across selfbondage shop.
I ordered a wooden pillory with a magnetic lock, but it was no longer in production (but it is still on the site). The owner of the shop contacted me and asked if I would like a 3d-printed pillory instead and I accepted, it came with a automatic time lock and all.    
When it all arrived I tried toying around with it, but the time lock either stops drawing power from my power bank or doesn't draw enough power becaue it always opens after max 10 minutes when my bank powers down. Getting acces to the timer via phone is also hard, slow, prone to disconnects.
But who needs an automated timer when you have dice? I calculated that with my 20k powerbank 100% would be around 10 hours, so 20% about 2 hours. I rolled my d20 and got a 13, so I charged my powerbank to 13% and locked myself in. Nothing fancy, just this gag from Silencilicone     and a blindfold
So, I closed the pillory. The fun thing is, being in the pillory is not hard in the beginning. But ever so slowly you get uncomfortable. Because I was blindfolded there was no way to track time, but I think that after about 30 minutes my shoulders started to burn a bit. My cat also decided to keep me company and decided to lay down between my hands so I could pet her After an hour (I think) it was no longer burning, but my shoulders and back were hurting. And I loved every minute of it. I was hard from the very first minute. After about one hour and a half, I was released because my powerbank went empty and the electromagnet released the plate. I wanked and the orgasm was so hard it actually hurt. I can't remember coming so hard.
So, I'll will do this again, next time maybe 3 d10's and see where it ends.
If you are into selfbondage, the maglock is a very fun way to make it impossible to release yourself. Is it dangerous? Of course it is, but as I never found anyone to share my passion, it is a risk I'm willing to take.

I came across the selfbondage shop myself and I was wondering how do you prevent yourself from being able to just disconnect your power bank? I like to roll around and struggle in bondage and the scenarios I could think of with their electro gear where all scenarios where you lock yourself in place on a bed or chair.

1) I tape the cable to the pillory, every time I move, the cable moves with it.
2) I'm on my bed, the powerbank is on the floor, I can't get there without falling
3) Now you reminded me I can try and crawl a wee bit around, I'll either put multiple socks (pillory won't hurt my hands as much, that's a plus too) over my hands or use my bondage mittens with segufix locks

Sounds like a fun, if slightly uncomfortable arrangement. Not that you are going to go too far in a pillory, but could you attach the powerbank to the pillory? With a couple of holes drilled near the middle you could zip tie the powerbank to the side of the pillory facing you (opposite side from your hands.
