It does its job and does it well from what I've tried in the last 2 months, though with a bit of stress. The "short" plug for the SUP, the classic plug that corresponds to the one on its manual pump, and on an electric pump from another company, did not fit. So at first there was some disappointment. I tried swapping hoses between them and various such things (because due to its size, while it would go in, it couldn't lock) without any success.

However, the "long" one fit. It seems strange to me but since it works, I don't care further. The "problem" is the size of the plug's hose and the way it sits on the nozzle compared to the others I've tried, which is why the plug that should fit does not fit properly.

Anyone who has the same problem as me, I suggest trying my solution. Therefore 4/5 because it wasn't really plug n play, without wanting to diminish the product: Note that the job was really done very well and the pump is truly portable, something you don't easily find in the Greek market, just a shame that it had to give me a headache.

I haven't tried the deflate function.

one star for 2 reasons
1. none of the adapters had proper contact
2. The noise during inflation is... deafening when the pressure exceeds 1 PSI so up to the 15 that I want, I’ll probably get chased away with stones!
The battery is enough for one inflation/deflation
I expected more
To solve the adapter issue, I replaced the built-in rubber ring with the one from the pump that came with the sap. Temporary solution but it worked

We received it! In less than 3 minutes we inflated our board to 15psi with minimal battery consumption! We also had a power bank with us but we didn’t need it, even though we experimented 3 times until we understood the settings!
What we haven’t managed yet is the deflation function! If someone knows and can help, I would appreciate it, although with a little patience I imagine we’ll find the solution!
It would help if the instructions were more detailed and in the Greek language!
