Ah, solar chargers. A fascinating concept, but in the real world, they're more of a gimmick than a practical solution. Sure, they can charge your devices, but don't expect miracles. Weather conditions can significantly impact their efficiency, and let's face it, the sun isn't always shining when you need it most.
And don't get me started on the charging duration. You'll be lucky if your phone is fully charged by the end of the day. Traditional power banks will always win in that department.
As for the size and weight, well, they're not exactly compact and lightweight. You'll be adding unnecessary pounds to your gear, which is the last thing you want on a long bike trip.
In short, solar chargers might be a fun toy for casual cyclists, but if you're serious about performance and reliability, stick to what works – traditional power banks.
