RovyVon has a really wide array of lights, though almost all of them belong to the keychain category. That can make things even more confusing because there are a lot of lights that look similar at first blush. Thankfully RovyVon recently posted a comparison chart of their Aurora series (that’s what they call the small, cylindrical keychain lights). As of the time of this writing, there are 7 different models, each of which comes in both cool white and neutral white. And a couple of the models (the A1 and A2) come in several body colors. Others (A5 – A8) come with different combinations of aux lights. Oh, and we’re now on the 3rd generation of Auroras – this one switches to USB-C charging and adds some other updates. So if you have trouble keeping them straight, you’re not alone. Just consult this handy chart.

The RovyVon that’s on the review docket today is the A2 model. It’s the stainless steel Aurora, which is what sets it apart from the others. This is the first one I’ve got my hands on from the new 3rd generation. So while I already really like the Aurora series, I’m anxious to see what updates have been made with this newest generation.

Package quality.

The packaging of this RovyVon A2 is the same as what I saw previously with the RovyVon A8x UV – a nice, plastic clamshell case. Only this time around, the plastic is black instead of clear. The A2 was held in place with a piece of cut-out paperboard, under which sat the accessories. In all, the package contained:

  • RovyVon A2
  • Pocket clip
  • Magnet tail base buckle
  • Split rings (two different ones)
  • Spare USB cover
  • Manual
  • Warranty card

Flashlight in use

Imagine you’re holding onto a AA battery, except it feels heavier than usual. That’s about what it feels like to hold the RovyVon A2. It is small, steel, round, and a bit heavy for its size. While there is no knurling, there are three slots on the sides that can be used for attaching the pocket clip – these slots help to add a decent amount of grip.

Speaking of the pocket clip, the included pocket clip fits into those aforementioned slots on the side. It looks like there are three possible placement options for the clip, but it really only makes sense to install it in the position closest to the tail. That said, the clip can be installed in either direction for your choice of tail-up or head-up carry. Oh, and one of the improvements for the 3rd generation of Auroras? The pocket clip has a slim magnet that runs the length of the clip.

Keeping on the topic of magnets, the 3rd generation of Auroras also introduced a new accessory: something RovyVon calls the “magnetic tail base bucket.” That’s a mouthful. It’s essentially a piece of plastic with a strong magnet in it that clips to the tail, making the light just a bit longer and giving you tail-magnet functionality. At first I thought “there’s no way that thing is staying clipped on for long.” I think I’m quite wrong about that. I tried to pry it back off and couldn’t do it with my fingers. I had to get a thin metal tool to carefully slide under it to pop it back off.

RovyVon threw in two different split-rings / keyrings. One is a bit larger and flat; the other is smaller and rounded. The light can tailstand, though it’s not very stable. The only switch is a single e-switch on the side of the head. This button is yet another item on RovyVon’s improvements list for the 3rd generation: they increased the button area by 50%, making it easier to press.

This is a keychain light, so keep your expectations in check. It boasts 650 lumens in a tiny package, so it’s good for either short bursts of bright light (like navigating to your car or door) or longer running low-light tasks (like reading a book).

Build Quality, and Warranty

Almost all flashlights that are sold are made of aluminum, at least most of the lights worth talking about. You know what material RovyVon doesn’t offer in the Aurora series? Aluminum. I’m not going to complain about that, I like to see things get switched up. The materials offered are polyamide, stainless steel, titanium, GITD (glow in the dark) polycarbonate, and clear polycarbonate. The A2 that I’m reviewing is the stainless model which means it’s the heaviest of the bunch – more than twice the weight of the lightest model , the polyamide A1. The A2 I have in my hand is the natural “silver” option, but it also comes in PVD Blue and PVD Matte Black.

Thanks in part to the heft of the stainless construction, the RovyVon A2 feels really solid. The machining is very clean and smooth. The unit is sealed up, which is ok since most people have no business opening this thing up. As a modder that might want to change LEDs, I’m not a huge fan of the glue, but I have been able to break through it in the past (warning – doing so will probably void your warranty!). Everything seems very well put together and well executed.

Warranty Policy (copied from RovyVon’s website):

  • Within 2 years of purchase, we will replace or repair it as long as the product is not working anymore because of the factory defects. This does not include obvious user wear or extreme damage.
  • After 2 years of purchase, if your product(s) got a defective or issues, we’ll offer a discount for purchasing new product(s) at a same or similar value.

LED, Lens, Bezel, Beam, and Reflector

Throughout the entire Aurora line-up, RovyVon offers two emitter options: a cool white, 70-CRI Luminus SST20 and a neutral white, 90-CRI Nichia 219C. Like most LED choices, it’s a trade off between quantity (lumens) and quality (color rendering). I have the cool white SST20 version. All of the Aurora series (except for the A4 pro) use a TIR lens.

Like most TIR lenses, there is a defined hotspot with a light spill. The hotspot has some small tint variation throughout, which is pretty normal. The transition to spill has some slight variation in the form of rings as well – I’d describe them but I’m not good with colors.

Driver & User Interface:

RovyVon’s UI is a bit unique. At first, I was turned off by it. But after carrying the A8x UV in my pocket for the past month or so, I’ve gotten quite used to it. The UI is certainly different, but it seems purpose-built for pocket carry with a focus on preventing accidental activations without making you use the lockout mode.

Available modes: Moonlight, Low, Medium, High

Available blinky modes: Strobe

User interface:

From OFF:

  • Press and Hold 5 seconds: lockout 
  • Double click:  turn on
  • 3 clicks: Strobe

From ON:

  • Press and Hold 0.5 seconds: turn off
  • 1 click: change modes
  • 3 clicks: Strobe

Mode memory:

  • Yes, after you stay in a mode for 3 minutes, it will remember that mode
  • This sort of mode memory takes some getting used to, but since there is no shortcut to Moonlight, I try to make sure I keep the mode memory locked in on Moonlight. It’s a little annoying, but it works.


  • To Strobe: triple click from Off or On

Low voltage warning:

  • N/A


  • Strobe: triple click from off or on

Lock-out mode: 

  • Previous Auroras did not have a lockout mode, but RovyVon added that in this 3rd generation of lights
  • Hold the button for 5 seconds to activate lockout – it’ll flash twice to let you know you’ve done so
  • Once locked out, hold the button for 3 seconds to unlock it


  • Yes, I’ve measured 23.4 kHz PWM which is fast enough to not be noticed by most people

Additional info on the UI: 

  • This UI is pretty similar to other Auroras that I’ve used. It adds a lockout mode, which is nice. But one thing seems to be removed – a momentary High mode. I’m not sure why that is gone. And even though I don’t use it too much, I do miss it a bit.

Batteries & Charging

RovyVon lights have pretty much all used micro-USB charging, and that was a big turn-off for me.  While I appreciate the built-in charging, I swore off any more flashlight purchases that used micro-USB. Well, that makes the 3rd Generation Auroras a breath of fresh air because they’ve finally converted over to USB-C charging.

The built-in LiPo battery is rated at 300 mAh. The charge rate is stated as 350 mA and should be able to complete a full charge in 60 minutes. When plugged into my USB meter, I saw a 0.37 amp / 1.96 watt charge rate that completed in 1 hour and 7 minutes. The indicator LED next to the charging port lights up “breathing” blue when the A2 is charging and turns green when the charge cycle is complete.

Performance test

Lux was measured by a UNI-T UT383 BT at 5 meters. Lumens were measured in a homemade lumen tube using a TSL2591 sensor, calibrated with a Maukka calibration light. The temperature was monitored with a MLX90614 IR temperature sensor.

Medium200 lm21318290
High650 lm633394118

Parasitic drain:

  • N/A (can’t measure due to internal battery)

Overall, my measurements are pretty close to what RovyVon says they should be.  But not if you follow the ANSI rating which measures the output at 30 seconds. The turn-on values match specs, but with High and Medium mode, output starts dropping immediately as soon as you turn the light on.

Battery Life: Runtime graphs

ModeSpecified runtimeMeasured runtime (ANSI)Time till shut off

Low6 hr5 hr 47 min5 hr 47 min
Med1 min + 1 hr 30 min1 hr 26 min1 hr 28 min
High1 min + 1 hr 15 min1 hr 4 min1 hr 7 min

The runtimes more or less are in line with what RovyVon claims.

ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

4.5 stars: ★★★★⋆

For a long time, I’ve loved the RovyVon Aurora series from a distance. But after reviewing the A8x a while ago, it just never left my pocket at night (having replaced my Sofirn C01S). It still bothered me that it used micro-USB, but it never kept me from charging it when I needed to. Now that RovyVon Aurora 3rd generation has been released, my list of complaints with these little lights has been reduced to a couple nit-pick items about the UI (could we get a shortcut to Moonlight and/or High?). From my understanding, RovyVon was the pioneer of this keychain form-factor and is often imitated. With the release of the 3rd generation of Auroras, I think RovyVon still reigns supreme.
