I am using this on my moped bike - Honda RS150R v2 (known as Winner in Vietnam for your reference). I want to install a dashcam and a USB-C charger on board and i want a reliable power source without tapping directly into the battery. The daytona WR 3 is very good, each line is fused at 5A, and a pair of 7.5A. It is waterproof as well but i installed it behind my headlight so there's minimum risk of water exposure.

**Keep the terminal connections away from water.
*PTC thermistors manage the current flowing through them by heat and resistance values.When the current exceeds the specified current, the resistance value becomes high (high temperature) and it will shut down.If an electronic device is left connected in this state, the temperature will not drop and there is a possibility that the body will melt.If the connected equipment stops working, disconnect it as soon as possible.
*Because the unit itself generates heat, it is not recommended to install the unit under the seat or in other places where heat is likely to accumulate.
*Please do the wiring processing separately for the connection to each electric equipment.
*There may be changes in product specifications due to the manufacturer's reasons..

I purchased this for charging my phone and for navigation power. I chose this one because the power supply around the handlebar is messy, and I installed it under the Seat, even though the body is supposed to be waterproof. It works fine. I recommend it because it is inexpensive.

For future electrical equipment.
I installed it while servicing my ZOOMER. I had previously installed D-UNIT, a different version of this product, on my ZX-10R, but was attracted by the waterproof specification and compactness of this product, so I installed it on my ZOOMER as well.
I installed it in the position shown in the picture, and the ACC power is supplied from BlinkerWiring. The work itself is not difficult, but if you do not have basic knowledge of electrical systems, it would be safer to ask a shop to do it for you. After installation, check the power with an energizing tester. We are planning to install Fog light etc. in the future.

After installing the driver's license camera, I will also install ETC in the future and may buy electric heating wire next season, so I installed it to facilitate wiring.
I was torn between other products in the Series, but I didn't need a constant power supply and I was worried about the shape of the product.
Select this one, which is the simplest, smallest, waterproof, and lowest price.
Since it was after installing the driver's camera, I redid the wiring from the middle of the process and installed it and Refreshing it.
If multiple power distribution is required, it is good because once it is attached, the rest is easy.
