[Review] Rovyvon Aurora A33 || Penlight, Nichia 219C, 600mAh Li-Po , Type-C || Output and Power Regulation Tests

The flashlight was sent to me by Rovyvon for review.
Here's the product's link: Rovyvon Aurora A33 

The A33 comes a black cardboard box.



Other than the flashlight, the following accessories are included in the package:

  • Type-C charging cable.
  • User manual.
  • Warranty card.



Here's a photo of the included manual that showcases the mode spacing and expected runtimes.



The Aurora A33 is part of Rovyvon's penlight collection.



The flashlight is available in a variety of colors (Black, Gunmetal, Red, Dark Green) and emitters (Cree XP-G2, Nichia 219C).
I chose to go with Gunmetal and Nichia 219C.



The body of the flashlight contains some horizontal and spiral knurling for added grip.



The A33 is operated via an e-switch.
The metallic e-switch is mounted on the tail of the flashlight.



The switch is completely flat and doesn't protrude, which allows the flashlight to tailstand.



The front bezel is very subtle and flat.



The Nichia 219C is perfectly centered into the TIR lens.



The Rovyvon logo and model are displayed in the front of the flashlight.



Of course, the A33 wouldn't be a proper penlight unless it arrived with a proper pocket clip.
Its pocket clip is very robust and it allows for a deep pocket carry.



The penlight comes with a 600mAh integrated LiPo battery.
Twisting its tail piece reveals its USB TYPE-C charging port.



Thanks to the rotating tail piece, the charging port is completely sealed when not in use.
Here's a pic of the threads and o-ring of the rotating tail.



Once plugged in, an indicator LED will shine to indicate the battery's charge level.
Breathing Blue = Charging - Solid Blue = Full.



According to the manufacturer, a full charge requires ~ 70 mins.
While charging the A33, I recorded a maximum input current of 480mA.



User Interface

Here's a list of all the supported actions of the Rovyvon's A33 firmware.

Turn on/off: Long press ( 0.33s)
Mode cycle: Single press ( Moonlight > Low > Mid > High > Moonlight > .. ) 
Strobe: Triple press.
Turn of at last used mode: Double press.

As you can see, mode memory is present, but the user has the ability to choose to either turn the flashlight on at the default mode (Long press) or at the last memorized mode (Double press).
Low Voltage Warning is set at 2.8V.
Low Voltage Protection is set at 2.6V.

Output

Here's my output measurements for the Rovyvvon Aurora A33 w/ Nichia 219C per each output level.
Since the A33's battery is integrated, I wasn't able to also record the corresponding power draws.



The penlight is able to produce 161 lumen at High.
The A33 is not indented to be a performance monster. Instead, it's a subtle EDC penlight, and its maximum output is more than enough for day-to-day tasks.

Power Regulation

Here's a power regulation graph that I created for the High mode of the A33 on a 15min run.


The flashlight shows signs of great regulation.
The full output is held steady during the whole test.
As a side note, it's worth noting that the A33 got warm but never too hot to touch / operate.

Bottom line

The Rovyvon Aurora A33 is a neat little EDC penlight.
Its build quality is on point, its charging interface and design is great and it produces an adequate amount of output for daily tasks.
Extra points given for the great mode spacing and the ability to get it with a High CRI Nichia 219C emitter.

The one thing I would like to see improved is having a more advanced UI.
For example having quick access to Turbo and Electronic Lockout would certainly be desirable.
