As first-world problems go, there aren't many that cyclists will be more familiar with than kitting up for a ride, only to find that your bike computer's battery is flat just as you're about to head out the door. If not that, then it's the anxiety of an old computer's battery draining from full to flat while you're following a route, hoping you'll hit familiar territory before being plunged into digital darkness. 

It's one of the biggest complaints I had with the Hammerhead Karoo 2, whose battery lasts somewhere in the region of 8-10 hours, and though it's my go-to computer at home, it was forced to sit on the sidelines when I tackled the Chasing Cancellara 275km sportive in 2022.
