Regular maintenance is not needed daily; lights don't break daily. Charging a light is not a "problem". Buy a few lights and then charge them all at once in one weekly charging session or something.

"Not robust enough"... for what activity are they not robust enough?

"Safe & usable mapping system"... Cyclists shouldn't be looking at maps while riding. Stop and use your phone if you get lost. Also.. most cyclists don't need maps unless they're tourists, who will happily stop and use phone because tourists ride slowly and stop frequently.

Sounds like you're over cycling. Get yourself a motorbike or car or electric bike!
