Manker E04 (E04) specifications

Rated 4/5 based on 1095 user votes.

The E04 flashlight enhance personal safety and security. It allows you to illuminate dark areas, identify potential hazards, or deter threats by shining light on them.


Weight34 g
Length55 mm
Head diameter22 mm
Materialaluminium alloy with HAIII hard-anodized finish

The E04 is small, compact, and designed for ultra-portability. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. The aluminium body of E04 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. The E04 flashlight is offered in a stylish black color.

Lenstoughtened AR coated glass
Switchelectronic front

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the E04 flashlight. The E04 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.

Throw28 m
CD/LM factor0.36

550 lm can provide a decent amount of brightness and be suitable for many everyday tasks, it may not be sufficient for certain scenarios or individuals with specific requirements. 200 cd can provide a reasonable level of luminous intensity for many everyday lighting tasks. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The E04 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The strobe function on the E04 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect. The E04 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

The power source of the E04 flashlight is 1 x 16340 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

The E04 cannot charge batteries directly. You may need an external charger to keep your battery going. When the E04 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. Flashlights without thermal protection may be more susceptible to overheating under extreme conditions, such as prolonged high-output use or exposure to high ambient temperatures.

The "8" in the IPx8 rating indicates the highest level of protection against water ingress. Auxiliary LEDs provide additional lighting options beyond the main beam of the E04 flashlight. This feature can be especially useful in situations where you need a stable and directed light source while keeping your hands available for work or other activities.


Package contents16340 battery with microUSB
spare o-ring

By including a battery with the flashlight, you avoid the additional expense of purchasing a battery separately. Attaching a lanyard to your E04 flashlight provides an additional layer of security, reducing the risk of accidental drops or loss. Instead of searching for compatible O-rings or waiting for replacements to arrive, having spare O-rings readily available allows for convenient and immediate repairs or replacements.

The performance of the Manker E04 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.

The specifications above are based on the official data published by the manufacturer, but we also take user reviews into consideration. If you found an error or something lacking in the specifications above for the Manker E04, then don’t hesite and signal the problem to us.
