Spare Lezyne branded Micro-USB to USB (Universal Serial Bus) charging cable. Fits all Year 6 to current Lezyne LED lights & GPS units that require a cable to charge. Keep a spare cable at the office so you can top up the charge on your lights after your commute in. You never know when you might fancy taking the long way home. Please Note: We recommend you use Lezyne Micro USB (Universal Serial Bus) cables to charge your light. Often other brand cables have inadequate pin length to reach the contacts inside the light body & they will fail to charge your light.
