Bicycle lights with Power Bank function for charging external gadgets
Power bank mode
— the flashlight's ability to function as a power bank — an external battery for various portable devices, primarily smartphones and tablets.The Powerbank mode allows you to charge portable gadgets from the bike flashlight's own battery. It can be a real lifesaver in the wild or on the road when there are no outlets or other power sources nearby, and the gadget needs to be charged urgently (for example, if it's a phone used as the main means of communication). Of course, such charging uses part of the battery's energy and reduces the device's own operating time. However, models with this feature typically use fairly powerful batteries with a good energy reserve, and their autonomy remains quite decent even after operating in Power Bank mode.
