RovyVon Aurora A5 Keychain Flashlight Review
The RovyVon Aurora A5 keychain flashlight is another in the long line of Auroras, but it offers USB-C charging and more! Read on for testing!
Official Specs and Features
Here’s a link to the RovyVon Aurora A5 Keychain flashlight product page.
Versions
There are so many Aurora lights! Specifically, the RovyVon Aurora A5 keychain flashlight comes in some emitter option versions. The front emitter is available as Nichia 219c (seen here) in 5000K with 90CRI, but also a higher-output Luminus SST-20 at 6500K. The side emitters can be UV/warm white, or white/red(as seen here) (as seen here).
Price
The RovyVon Aurora A5 keychain flashlight is selling for $36.95 right now at RovyVon.com.
Short Review
It’s no secret that I love these little Aurora keychain lights. I’m pleased that this version offers two warm white side output levels as well as red. The other one I tested (which is the same except for red vs UV) had UV. I’m very sensitive to UV, so red is much better! USB-C charging is a great update, too.

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.
What’s Included

- Split rings (two types)
- Manual
Package and Manual
Build Quality and Disassembly
The RovyVon Aurora A5 keychain flashlight is nicely built. The body is fully plastic aside from the bezel, which appears to be stainless steel.
The body is also clear and glow in the dark, which means the internals may be viewed through the body.
Size and Comps
60.5mm x 15.6mm and 17g.
If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
Also above is the light beside my custom-engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats.
Retention and Carry
As with other Auroras, the RovyVon Aurora A5 keychain flashlight has a pocket clip. This does not ship attached to the light, and it has a new magnetic side feature! The magnet is perfectly strong for holding the light in any orientation.
RovyVon includes a couple of split rings of various sizes.
Not just the pocket clip, but the tailcap also has an attachment and that attachment also has a magnet!
This magnet too is strong enough to hold the light.
Power and Runtime
The battery is built-in and not removable or replaceable.
The light shuts off when the cell voltage is low, but I’m not able to test at what voltage it shuts off. RovyVon has confirmed that the shutoff voltage is 2.8V.
Charging
The RovyVon Aurora A5 keychain flashlight is charged via USB-C, which has a push-in rubber cover. This cover stays attached. The plug is a little harder to manipulate than most I’ve used, but it works just fine.
C to C charging works on my other similar models, but I haven’t tested it on the A5. Here’s a graph from testing of the A8!
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens |
|---|---|---|---|
| High | 420 | 1m+90m | 382 (0s) 259 (30s) |
| Medium | 150 | 1m+2h | 115 |
| Low | 20 | 8h | 18 |
| Moon | 0.5 | 72h | 0.23 |
| White Side Low | 10 | 6.5h | 7.88 |
| White Side High | 50 | 100m | 32 |
| Red | 25 | 100m | 11.2 |
Pulse Width Modulation
The order below is as follows: Four front white modes then two side white modes (low then high), then red. That’ll be the order for the rest of the images in sequence, too. Many of the modes use PWM. Most of the PWM is so fast that you’ll never be able to notice it.
Here you can see a “baseline” – a chart with almost no light hitting the sensor. Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.
User Interface and Operation
There’s a single side switch for operating the RovyVon Aurora A5 keychain flashlight. It’s a clicky e-switch.
The user interface is fairly versatile. Here’s a user interface table!
| State | Action | Result |
|---|---|---|
| Off | Click | No action |
| Off | Hold | No action |
| Off | Double Click | Front (main) light on in memorized mode |
| Front Light On | Click | Mode Advance (L, M, H, Moon) |
| On | Hold | Off |
| Off | Triple Click | Side White On |
| Side Lights on | Click | Off |
^ After a certain amount of time being “on” the next click turns the side light off.
LED and Beam
The main emitter here is a Nichia 219c with 5000K and 90CRI. That’s great! The tiny optic makes the beam very usable, too.
LED Color Report (CRI and CCT)
The order is as above. It’s nice to note that RovyVon gives accurate data on the 5000K emitter, and the CRI (at 92) is a bit better than the specification!

Beamshots
These beamshots always have the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left and the BLF-348 reference flashlight on the right.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
Conclusion
What I like
- USB-C charging is a nice update
- C to C charging works!
- Nichia 219c emitter at 5000K and 90CRI is a great choice
- Side emitter options are robust
- Magnets on the pocket clip and tailcap are useful
What I don’t like
- Output falls below specification
