Keychain flashlights used to have one job: make enough light to find the keyhole without accidentally unlocking your neighbor's door. These days? They're practically miniature multitools.
The WUBEN E2 and WUBEN G5 take two noticeably different approaches to pocket-sized lighting. The E2 is ridiculously light at just 10.7g and packs three types of lighting into a coin-sized body. The G5, meanwhile, brings a much stronger 400-lumen beam, a rotating head, and a tougher metal construction.
So, Wuben E2 vs. Wuben G5: Which Keychain Flashlight Is Better? That depends less on which one has the bigger number on the box and more on what you actually expect your tiny flashlight to do.
Wuben E2 vs. Wuben G5: Which Flashlight Is Better for Everyday Carry?
For genuine keychain carry, the Wuben E2 has a pretty obvious trick up its sleeve: you barely notice it.
Measuring only 19 × 14.6 × 41.4 mm and weighing 10.7g with its battery, it's the sort of flashlight you can leave attached to your keys permanently. No bulky pocket, no jangling brick hanging from your keyring.
The G5 is still compact at roughly 37 × 15 × 62 mm, but its 52g weight makes it substantially more noticeable.
In simple terms:
- E2: Better for minimalist, forget-it's-there carry.
- G5: Better if you're happy carrying extra weight for considerably more lighting power.
If your keyring already looks like a janitor's starter pack, the E2 is probably the friendlier choice.
Brightness: The G5 Isn't Playing Around
Here's where things flip.
The Wuben E2 pulse reaches up to 150 lumens, with a beam distance of around 26 meters. That's plenty for checking under a car seat, walking through a dark hallway, finding something in a backpack, or dealing with a surprise blackout.
The Wuben G5 pushes output all the way to 400 lumens and reaches approximately 82 meters.
That's not a small difference.
For outdoor walking, campsite use, scanning a backyard, or simply wanting more visibility ahead, the G5 wins the brightness battle comfortably.
Wuben E2's Secret Weapon: Three Lights in One Tiny Body
Looking only at lumens would sell the E2 short.
Its 3-in-1 system includes:
- Main white light for normal illumination.
- Side white light for close-range tasks and area lighting.
- Red-and-blue signaling lights for attention-grabbing or warning situations.
The side lighting is especially interesting. Its dual COB LEDs produce up to 80 lumens with a high CRI of 90, while a lower 10-lumen setting works nicely when you don't need much light.
Then there's the heartbeat breathing mode. Instead of simply staying on, the light pulses rhythmically. Necessary? Probably not. Fun and distinctive? Yep!
The glow-in-the-dark body adds another neat touch. After absorbing light, it gives off a soft green glow, making the E2 easier to locate after the lights go out.
The G5 Fights Back With Flexibility
The G5 isn't exactly a one-trick lumen cannon.
Its 180° rotatable head lets you aim illumination where it's needed instead of repositioning the whole flashlight. Combine that with its adjustable clip, and it becomes surprisingly handy for hands-free work.
Clip it onto clothing or gear, rotate the head, and you've essentially got a tiny directional work light.
It also supports white light, RGB lighting, and beacon modes, giving it plenty of versatility for outdoor activities, emergencies, and everyday tinkering.
So while the E2 squeezes more lighting functions into an exceptionally tiny package, the G5 offers greater physical adjustability.
Magnets, Charging, and Durability
Both lights support USB-C charging, which means there's no need to keep some ancient mystery cable hidden in a drawer.
The E2 uses a built-in 120mAh Li-ion battery and includes a magnetic tail, letting it stick to compatible metal surfaces. That's useful when repairing something, digging through a cabinet, or improvising a hands-free work light.
Durability is another interesting comparison.
The E2 carries an IP66 rating and is rated for drops up to 1.5 meters. Its construction combines PC with an aluminum-alloy bezel.
The G5 uses a sturdier metal body and is designed to resist impacts and pressure, although its IP65 rating is technically a step below the E2's water-resistance rating.
Its bigger advantage is runtime: depending on the mode, the G5 can run for up to 65 hours.
Which One Should You Choose?
Think about how you'll actually carry the flashlight.
Choose the WUBEN E2 if you want:
- An extremely lightweight keychain light
- A tiny 10.7g body
- Main, side, and signaling illumination
- Magnetic mounting
- High-CRI close-range lighting
- A glow-in-the-dark body
- Something you'll genuinely keep on your keys every day
Choose the WUBEN G5 if you want:
- Much stronger 400-lumen output
- An 82-meter beam distance
- A 180° rotating head
- An adjustable clip
- Longer potential runtime
- A sturdier metal-bodied EDC light
Put another way, the E2 favors portability and functional density, while the G5 favors illumination performance and adjustability.
FAQs
Is the WUBEN G5 brighter than the E2?
Yes. The G5 produces up to 400 lumens, compared with the E2's maximum output of 150 lumens. Its beam also reaches much farther—around 82 meters versus 26 meters for the E2.
Which WUBEN flashlight is smaller?
The E2. At 41.4 mm long and only 10.7g, it's dramatically lighter and shorter than the 62 mm, 52g G5.
Does the WUBEN E2 have a magnetic base?
Yes. Its magnetic tail allows the flashlight to attach to suitable metal surfaces, which is especially convenient for hands-free close-range tasks.
Which one is better for outdoor use?
The G5 has the edge when you need to illuminate farther ahead thanks to its 400-lumen output and 82-meter throw. For lightweight emergency signaling or close-range campsite tasks, however, the E2's three-light system can be surprisingly useful.
Are both flashlights USB-C rechargeable?
Yes. Both use convenient Type-C/USB-C charging, so they're easy to top up alongside other modern EDC electronics.
Conclusion
Back to the big question: Wuben E2 vs. Wuben G5: Which Keychain Flashlight Better?
There's no universal winner because these little lights aren't really chasing the same goal.
The WUBEN E2 is the clever minimalist. It's tiny, featherweight, magnetic, glow-in-the-dark, and loaded with main, side, and signaling lights. If you want something that can live on your keychain 24/7 without becoming annoying, it's the more compelling design.
The WUBEN G5 is the miniature powerhouse. Its 400-lumen beam, longer throw, rotating head, adjustable clip, and extended runtime make it better suited to users who expect their compact EDC light to handle bigger jobs.
