Charging the E28R Rechargeable Flashlight

  1. First switch off the light and plug the USB A socket of the charging cable into an electrical outlet, then connect the USB Type-C socket of the charging cable to the light.
  2. The indicator will display red while charging, and will turn to green when fully charged.
  3. Once charging is completed, be sure to close the anti-dust cover. (The light features inner waterproofing treatment, thus the performance won’t compromise even if there is water in the charging port).


  1. The normal charging time of the included Fenix ARB-L18-3400 rechargeable Li-ion battery is approximately 3 hours from depletion to full charging, with 5V/2A adapter.
  2. Recharge a stored light every four months to maintain optimum performance of the battery.
  3. The relatively Eco output is available while charging, but the charging time will be prolonged.

Battery Level Indication

With the light switched off, single click the side switch to check the battery status, the indicator will last for 3 seconds.

  • Green light on: saturated 100% – 85%
  • Green light flashes: sufficient 85% – 50%
  • Red light on: poor 50% – 25%
  • Red light flashes: critical 25% – 1%

Note: This only works with Fenix ARB-L18 Series 18650 rechargeable Li-ion battery.

Intelligent Downshift

Time-limited Downshift
The light will downshift to 900 lumens within 30 seconds when it has been used on Turbo for 1 minute.

Overheat Protection
The light will accumulate a lot of heat when used on Turbo or High output level for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down by 5% every 10 seconds to reduce the temperature, and until to 350 lumens. When the temperature is reduced below 60°C, the light will automatically step up by 5% every 10 seconds, and it will then allow the user for the reselection of Turbo mode.

Low-voltage Warning
When the voltage level drops below the preset level of 3V, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the battery level indicator blinks red to remind you to recharge the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery level runs out or the protection board activates.

Note: This only works with Fenix ARB-L18 18650 Li-ion battery.

Usage and Maintenance of the E28R Rechargeable Flashlight

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent quality battery.
  • If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
  • Lock the light or take out the battery to prevent accidental activation during storage or transportation. Recharge a stored battery every four months to maintain optimal battery performance.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the lamp’s performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:
    A: The battery needs replacing.
    Solution: Replace battery (Ensure battery is inserted according to the manufacturer’s   specifications).
    B: The threads, PCB board contact or other contacts are dirty.
    Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don’t work, please contact your authorized distributor.


  • This flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the flashlight directly into anyone’s eyes.
  • This flashlight will accumulate a lot of heat when used for extended periods, resulting in high temperature of the flashlight shell. Pay attention to safe use to avoid scalding.

    great gift

  2. Joyce G. (verified owner)

    Nice general purpose flashlight for my wife. Very bright and broad beam. Love the side button, like a conventional flashlite, but the button is too flush to find easily in the dark. USB-C charging is very nice convenience. All-in-All a great general purpose camping light for ladies and children.

    • Dianne

      One way to find the side switch in the dark is to line up the clip with the switch.

    great light

    Over the past year, I have visited your website site regularly to see the new products that are available. I have purchased “5” of the most sophisticated items you keep manufacturing. The E28R Model -Rechargeable has the power & ability to provide anyone with the
    protection at night or when you want to let anyone know that you are present.
    I must add that my best friends are
    ranking Officers on the New Jersey
    State Police, and each one only has
    Fenix Flashlights!!

    I’m really enjoying this little powerful light. The fact it can be charged by a USB type a plus, or throw some Cr123 batteries in it. The lock out feature is great so it doesn’t come on in my pocket.
    I ordered a diffuser, thinking it would fit, but it doesn’t. Luckily it fits another Fenix light I have. Hopefully they will have one soon for tail standing.
    Love the copper accents. Just the right size and my android phone charger will keep it charged. Well thought out design.

    Easy transaction, quick shipment, light works very well.

  8. Marcel (verified owner)

    Great fit and finish! It’s lightweight and very bright. It fits nicely in the hand. I only wish that the On button was easier to find by feel. Otherwise this light is fantastic.

  9. jpoun7

    Love the E28R, just wish they had a diffuser tip for this tail stander.

  10. Joseph Haupt (verified owner)

    It’s a great light but the side button makes it a little too easy to turn on in my pocket. But it’s super bright I just wish it had a tail switch.

  11. Bonnie H. (verified owner)

    Very happy with this light. I live in the country and when I take my dogs out before bedtime, it is so dark you cannot see anything. We have bear and coyotes here and I can light up the whole area to make sure my dogs will be safe. Love it!

  12. Garry P. (verified owner)

    Awesome EDC flashlight.

  13. Guy R. (verified owner)

    I really like the E28R but there is a learning curve. A tail button would be an improvement as the side button can be difficult to locate by feel. The charging port is excellent.

  14. david strilich (verified owner)

    Love the light
    But the light keeps coming on in my Engineers pocket. Gets hot quick in your pocket

    • Dianne

      Please note this light does have a lockout feature to prevent this from happening. If you no longer have the operating instructions, this information can be found on our product page.

      Lock: with the light switched off, double click the switch within 0.5 seconds to lock the light, the light will blink twice on Eco to indicate locked status.

    Amazing light from a tiny edc. I had a PD 35 for the last 7 years I carried everyday at my job in building maintenance and loved. It turned up missing and I immediately went to Fenix for a replacement and selected this E28R. I’m blown away by the brightness and battery life. I live in Alaska and flashlights are a part of life, especially all winter when the days are only a few hours long. I’m recommending Fenix lights to everyone I know and even to strangers who are noticing and being impressed by the power this little, affordable light. If it is half as durable as my last light it’s going to survive freezing temperatures, complete immersion in water regularly, and quite a few bangs and bumps without any issues.

    Simple one button operation opens up from “off” in your choice of lowest level output, or from memory of your last output level used. No tactical button on the end required. No “special” rechargeable battery needed, just common & powerful 1860 or CR123’s. Charge in the flashlight or in a separate charger. Wide spill and lights up the area ahead bright as you want. Very small and pocketable. Very happy camper here and I suspect you would be, too!

    Great EDC Flashlight, powerful compact, nice gadget, perfect size for your pocket

  18. Craig C. (verified owner)

    Excellent light for the price and size!

  19. Clifford (verified owner)

    I prefer the tail switches on my other 2 Fenix flashlights as I think they guard against accidental ON situations a little better. That said, it is still a very nice flashlight for the money. These Fenix lights are very rugged and I use them daily for work. I would rate as a 4.5 if I could!

    • Dianne

      Hi Clifford – this light does have a lock out function to guard against accidental activation:

      Lock: with the light switched off, double click the switch within 0.5 seconds to lock the light, the light will blink twice on Eco to indicate locked status.

      Unlock: with the light locked, double click the switch within 0.5 seconds, the light will be unlocked and activated on Eco.

      *In locked status, clicking or pressing the switch will activate 2 one-second blinks on Eco to indicate locked status.

    Best flashlight so far

  21. Frank (verified owner)

    This is something I keep in my jacket pocket for when I take the dog out. The first three levels are good for general use and the last two are for, “What IS the dog barking at?” The answer is usually, one or more deer passing through the empty lot next door.

  22. Alan (verified owner)

    I love it – small bright and works everytime

  23. sang ki l. (verified owner)

    This is powerful light!!

  24. Willard Baldwin (verified owner)

    Very reasonable price for a flashlight of this quality. This is a pocket size flashlight has high lumens usually found in a large size or others costing much more.

  25. Duane B. (verified owner)

    Predict charge port cover will be a weak spot. Otherwise a good light

  26. Bo S. (verified owner)

    Should have tail switch

    • Dianne

      We have many lights that have a tail switch, but also have several that are side switch only. The description of the lights will tell you if there is a tail switch.

    Excellent BRIGHT flashlight!
