Ever arrived somewhere and realised your phone has a flat battery? It’s more than a little inconvenient. Especially if you use your phone for communicating, photos, directions and finding petrol stations. Or to wind up your mates at home by sharing pictures on Facebook. So the OptiMate USB 0-108 On-Bike Charger isn’t glamorous. But it is an easy way to add a useful USB charger to your motorcycle.
USB chargers aren’t rare. But you tend to get what you pay for. So the 0-108 comes with waterproofing as standard and has been built to stand up to the exposed conditions mounted on a motorcycle.
The USB charger delivers 3.3A, which will cope with new devices using USB-C connections, but also has a built-in microprocessor to stop you flattening your bike’s battery in the charging process. That’s also why charge is limited to a maximum of 3 hours (Are you likely to leave your phone on your bike for longer?) and the automatic cut-off will kick in when your bike battery drops below 12.3V which is roughly 50% charge.
It even has an LED display so you can see the charging voltage. Something to keep you entertained as you sit on your bike to prevent your phone being nicked while it powers up. The OptiMate 0-108 is 100% true power rated, and delivers a continuous, consistent charge. It also has a built-in Apple ‘handshake’, to make sure iPhones and iPads charge correctly.
The OptiMate USB 0-108 On-Bike Charger costs £32.99. As someone who lives by his phone (often doubling up for work and personal phones), it seems like a reasonable price. Nothing worse than missing out on your mates at a bike meet. Except bumping into a motorcycle legend and not being able to take a selfie for proof.
