The Fenix E-SPARK is an ultra-thin rechargeable keychain flashlight that is capable of a 100-lumen max, perfect for emergencies or everyday carry. The E-SPARK is only 8mm thick and is about half the size of a credit card, perfect for slipping into a pocket or carrying on a keychain.
The E-SPARK has a built-in 800mAh rechargeable battery that not only can power the flashlight but also double duty as a power bank. The parallel male and female USB-C ports provide fast USB charging of the E-SPARK or fast discharging to power other electronic devices. The flush fit when it is plugged into mobile devices looks great and feels secure. This little battery can power the E-SPARK for up to 52 hours.
The single side button controls the light and even has three settings for lighting control. The diffuser provides a nice even coverage almost like a mini lantern providing ample lighting for simple everyday tasks. Additionally, the E-SPARK features a red LED for low-light optics, or as an emergency signal.
