Why The Mini Diving Tank Hand Pump Is a SCAM

They say you easily and effortlessly can fill a scuba diving tank with a hand pump, but how effortless is it actually?
I tested how long it actually takes to fill a scuba tank with a hand pump?

Download the manual from their site and here’s the parts they don’t tell you in these shorts 1. You should be scuba certified. 2. Max 3m (~9ft) 3. The tank can hold 200 bar or 2900 psi - you will be there all day hand pumping that

Kinda a scam. NO most people are not strong enough to fill the tank by hand pump. Pressure against the pump increases to the point (thousands of psi) that you'd have to be a power lifter.

What about using an air compressor instead of pumping?

[@mufuliramark]

Please excuse my ignorance but what difference does a scuba licence make, to make this dangerous if you don't have one....

Gets you in shape to go diving!

Seems like the issue is the pump. These are multi-stage pumps, they should have designed the final stage piston/chamber with a diameter of 5.6mm. This would give a reaction (pushback) force of just 50kg when the piston hits 200bar (200kg/cm2 acting on 0.25cm2). Looks like the central final stage piston is too big a diameter. Of course this would need even more pump strokes to fill!

I'm curious as to what other manual pump designs there are, this seems pretty inefficient but there must be a reason the design didn't change, maybe a geared bycicle would do great, it could adjust to the load and legs are quite good at hard continuous work.

Fun fact, using a cheaper pump may result in the air hose failing after heavy usage, I had a bubble form in the line and subsequently burst after we had to air up a truck tire in the middle of nowhere.
