[Review] Rofis MR30 (XHP35 CW , 21700 , Rechargeable) Outdoor Beamshots, Output Measurement, Charge / Discharge Tests

bilakos10 · 2018-11-18T11:36:00.000Z

The flashlight was sent to me by Rofis for review.
Here's the product's link: Rofis MR30

The flashlight arrived in a typical Rofis branded cardboard box.

Rofis has been consistent across its MR-line and always includes a carrying pouch and the required cables.
+1 for the fact that both cables (micro USB & OTG) are braided.

The pouch is made out of nylon and it's overall quality is on point.

The pouch integrates both a permanent belt loop as well as a button secured one.

Since I was at it, I went ahead and measured the resistance of the USB cable.
It turns out that the resistance is around 0.28Ω.

Additionally, the accessories list also includes an adjustable lanyard, 2 spare o-rings and a replacement charging rubber plug.

The MR30 comes with a flat black anodization.
It's side switch operated and is running on an 21700 cell.

The side e-switch is covered by a rubber boot and is surrounded by a gun-metal grey metallic ring.
Having reviewed quite a lot of ROFIS lights, I am quite confident to state that their switch design and feel / feedback
is my favorite among all the other lights I have used.

The e-switch includes an indicator LED which is used for night beacon as well as to report the battery's charge level.

Opposite to the switch, there is the integrated charging interface.
The regular microUSB port is protected by a rubber plug which creates a tight seal.

The body is full of the excellent knurling that ROFIS applies on their flashlights.

The tailcap incorporates a double spring design.
A thing that caught my attention is that the springs' surface are exceptionally polished.

The threads are cleanly cut and arrived nicely lubricated.
Due to them being anodized, the user can mechanically lock out the flashlight.

The head houses the orange peel reflector and the XHP35 CW emitter.
Of course, the emitter is accurately centered.

An 21700 Rofis branded cell is included into the light.
The rated capacity of the battery is 5000mAh and it seems to include a protection circuit.

The positive contact of the cell is flat, though the whole metal piece is protruding from the wrapper.

The negative contact on the other hand sits below the wrapper's height.
You can also easily see that that's where the protection circuit is installed.

Thanks to the USB interface, the flashlight can be both charged as well as used a go-to powerbank.
With a fairly discharged battery, I measured 1.93A of peak charging current.
To get my discharge figures, I utilized my RDTech UM34C meter and LD25 electronic load.

Here's a plot for the V/I curve of the powerbank function of the MR30.
As you can see, the flashlight's circuit is good for up to 2.1A of discharge.

The flashlight weights 74g, which is quite light for its dimensions.

The cell adds another 72g of weight.

User Interface

As always, Rofis chooses very neat user interfaces for its lights.
Here's all the operations supported:

Turn on/off: Single press.
Mode cycle: Long press ( Low > Mid > High > Low > ... )
Turbo: Double press from anywhere.
Strobe: Triple press from anywhere.
SOS: Long press while in Strobe.
Lock / Unlock: Long press while off until two flashes occur (4 seconds).
Location beacon: Long press while off until the indicator Led flashes in red (2 seconds)

It's worth noting that both in charge/discharge function, as well as during normal usage the indicator LED will shine in different colors to indicate the battery's power level.

Performance

In order to get my measurements I used the include 21700 cell.
Here's each level's current draw along with my measured lumens.

And here's Turbo compared to my other lights.

So we are looking at 1600 'bilakos10' Lumens :)
The standby drain was measured at 150μΑ with spikes to 210μΑ at constant intervals.

Overall we got another great EDC light by Rofis.
It provides a nice flood / throw combination and thanks to massive 5000mAh 21700 you should be getting great runtimes.

Nice review . Sorry I missed the Amazon deal on this light. Next time.

At what battery voltage does the light stop outputting USB power?

Unfortunately, I wasn't able to test that due to the head being stuck to the body.
Otherwise I would have powered the flashlight with my bench PSU and would have provided a greater deal of info ( regulation, lvp and so on).

I have ordered some strap wrenches from eBay, but they are on the slow ship from China.

Black Friday is about to arrive.
I am pretty sure than one way or another, a deal for the MR30 will definitely pop up.

The Vipon deal is still active. I just ordered two more MR30 lights for just under $30 each. I love this light. Since these lights come with protected cells, I figure I can just leave them plugged into a USB charger and they will always be ready to go- no need to lock out the tailcap and no worries about the parasitic drain.

Oh wow, that’s an excellent deal.
Also, no need to worry about the parasitic drain.
According to my calculations, it would take around 3 years for the battery to be discharged!

The Vipon/Amazon deal for the MR30 is even better right now. Amazon has an additional 5% coupon for this light that stacks with the Vipon code.

Haha, it’s getting even better by the day.

The MR30 has been my goto flashlight for the last week and I am more than pleased by it.
Definitely loving the minimal UI that Rofis chose.

Here are the measurements of my MR30 in the Texas_Ace Lumen Tube. These are the only 21700 cells I have right now, but I have a couple more high current cells on the way.
