The Fenix E35R is our best camping flashlight pick, and it scored 84 out of 100 in our testing.

A compact 3,100 lumen camp and EDC light with clean USB-C charging and a wide mode range, whose big peak is again a brief burst that settles far lower.

A 4.72 inch 3,100 lumen light on a removable 21700 cell with side USB-C, earning the camping pick on its wide Eco-to-Turbo range and pocketable size.

Now:

We tested it head to head against the other top rechargeable flashlights, and below we break down how it did on Battery Life, Brightness, Beam Quality, Ease of Use, Durability, Features, where it falls short, and whether it is worth your money.

Bottom Line : A compact 3,100 lumen camp and EDC light with clean USB-C charging and a wide mode range, whose big peak is again a brief burst that settles far lower.

Pros

  • Wide Eco to 3,100 lumen range
  • Removable 21700 with spare-battery bundle
  • Standard USB-C charging
  • Compact 4.72 inch body

Cons

  • 3,100 lumen peak is a short burst
  • Cool tint, not warm for camp
  • USB-C flap can wear

Our Verdict: Fenix E35R

A compact 3,100 lumen camp and EDC light with clean USB-C charging and a wide mode range, whose big peak is again a brief burst that settles far lower.

A 4.72 inch 3,100 lumen light on a removable 21700 cell with side USB-C, earning the camping pick on its wide Eco-to-Turbo range and pocketable size.

So, is it any good?

The 3,100 lumen Turbo is a burst rating; High and Turbo are temperature-regulated and step down as the head heats.

An intelligent downshift lowers output as voltage drops, protecting runtime toward the end of a charge.

The Eco mode lasting nearly three days meant I barely thought about charging on a weekend trip, and the size disappears in a jacket pocket. Turbo is more of a quick look-over-there button than something you leave running.

Our Analysis, Comparisons, and Test Results

The Fenix E35R scored 84 out of 100 overall.

It is strongest on brightness and weakest on features.

Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.

Battery Life

Runs a removable ARB-L21-5000 21700 cell, and a dual-battery bundle exists so you can carry a spare for long trips.

Wide mode range from Eco at 30 lumens for 69 hours up to Turbo at 3,100 lumens.

Turbo is rated about 2.5 hours in total but that includes the step-down, not 3,100 lumens sustained.

USB-C recharge of a drained cell takes about 3 hours, with a battery level indicator.

Brightness

The 3,100 lumen Turbo is a burst rating; High and Turbo are temperature-regulated and step down as the head heats.

An intelligent downshift lowers output as voltage drops, protecting runtime toward the end of a charge.

But here is the catch:

For camp use the mid and Eco modes matter most, and Eco runs an honest 69 hours.

The low-battery reminder blinks the indicator red once you reach Low on a depleted cell.

Beam Quality

Throw rated to about 260m (853 ft), a balanced beam for a camp and EDC light.

Smooth beam with a usable hotspot and spill for close camp tasks and mid-range.

Cool white tint, output-focused rather than warm.

Ease of Use

Side e-switch controls the full mode range, simple one-hand operation.

Wide Eco-to-Turbo spread means one light covers a headlamp-level low and a search-level high.

The USB-C port under a rubber plug keeps charging simple with no extra cable.

Should You Buy the Fenix E35R?

A compact 3,100 lumen camp and EDC light with clean USB-C charging and a wide mode range, whose big peak is again a brief burst that settles far lower.

It is best suited to campers and edc users wanting one light from low glow to high output.

Bottom line?

The big win: Wide Eco to 3,100 lumen range.

The main compromise: 3,100 lumen peak is a short burst.

We scored it 84 out of 100.

What Other Rechargeable Flashlights Should You Consider?

Not sold on this one? A few others from our testing are worth a look.

The Fenix PD36R Pro is our best rechargeable flashlight overall. The most complete tactical EDC here, with a genuine 21700 cell, USB-C, and a beam that stays usable long after the turbo burst fades.

The Coast G60R is our best waterproof rechargeable flashlight. A rugged twist-focus light sold as a two-pack, with a sealed USB-C battery and a modest but honest 1,000 lumens that does not oversell a burst number.

The WUBEN C3 is our best budget rechargeable flashlight. A lot of features for the money, with USB-C, IP68 sealing and a removable 18650, let down mainly by weak runtime once you push it on High.
