Push force of push / pull solinoids

Hi I am looking for a push pull solenoid they has a continuous rather than initial push force of 16N or above.

Has anyone had any experience with any of the adrftuit branded push pull solenoids do any have a force of 16n with the smallest about of power supply possibly as I would preffer my unit not need to be connected to a hard wired power source preferring a rechargeable interval battery and or able to have a small solar cell as a power source. All components need to ideally fit inside a 77mm diameter dome or cap
