DIY - Kawasaki USB Smartphone Charger Install

Many new models of motorcycles from Kawasaki now (finally!) come pre-setup for accepting a "bolt-on" charger. While installing a USB Charger (or 12v port) isn't all that complicated of an install on any motorcycle, it can be hard to locate a suitable location (including fairing cutting), as well as finding a switched 12v wire (which turns off when the vehicle is off) with sufficient current capability. Kawasaki now takes care of the electrical and location part of the equation for us. The only thing left is to install the thing, so let's do it!

Step 1: Which Bikes Does This DIY Apply To

Fitment

While this installation is being done on a 2017 Kawasaki Ninja 650 ABS, we can be presume that the process will be either identical or extremely similar for most of Kawasaki's new models accepting the same part. This includes, but is not limited to, the following models:

2017 Kawasaki Ninja 1000 ABS
2017 Kawasaki Ninja 650
2017 Kawasaki Ninja 650 ABS
2017 Kawasaki Ninja 650 ABS KRT Edition
2015-2017 Versys 650 ABS
2015-2017 Versys 1000 ABS
2015-2017 Versys 1000 LT
2015-2017 Versys 650 LT
2018 Kawasaki Ninja 400
2018 Kawasaki Ninja 400 ABS
2018 Kawasaki Ninja 400 ABS KRT

We can take for granted that future models of many of these bikes (and/or other models from Kawasaki) will also be compatible.

Step 2: What You'll Need

Main Parts:

12v Port - The hole in the motorcycle's fairing will fit most (if not all) standard 1-1/8" (2.85cm, roughly) dash panel mount devices. That's the diameter of your average "cigarette lighter" port. That will give you plenty of options regarding what to install there. That includes, but is not limited to, 12v direct ports/Cigarette lighter, USB Chargers, Battery Monitors, Switches, etc. Nonetheless, for the purpose of this DIY I think the two best options are:
- MICTUNING 4.2A Dual Port USB Charger with Voltmeter - These days, I wouldn't go with anything less than a Dual Port USB charger, with at least 2A per port, and an integrated voltmeter. The voltmeter can prove invaluable to let you know why the bike won't start, or if the voltage is so low you should charge it right away. It also helps out with alternator diagnosis, too. There just isn't really any benefit to not having one. If you want to see if Ebay has it cheaper, or other options, click here.
- BlueFire Waterproof Cigarette Lighter Socket + Charger - If you simply want a standard 12v cigarette port so you can plug in whatever device you like best, this is a decent option. One benefit is being able to use higher quality chargers, swap broken chargers, or being able to plug other devices in. However, since this wire is switched, you won't be able to charge your bike's battery through this port (which reduces the usefulness), and with the tiny 5A or under fuse, you won't be able to power devices like a tire air pump. Plus, you lose the waterproofness with the charger installed. I'd personally just pick the unit with the integrated USB ports, which is what you'll use most these days.
16 Gauge Speaker Wire - You can get away with less (thicker will probably be a bigger inconvenience), but 16 Gauge is a nice thickness for a project like this. Speaker wire is good since it's color coded and binded together. You probably already have some, somewhere, but if not a roll is great to have around.
Bullet Terminals - Another component that you probably have a few units of, somewhere, but if not an assortment is useful. Since I wasn't quite sure of the bullet connector size, I bought a connector set for this project. It ended up being your more or less standard, 4mm diameter bullet connector. You'll need one male, and one female to connect to the motorcycle.
Spade Connectors- Just about any DIYer with a garage has an assortment of these laying around. You'll need two female connectors of these for the charger side.
*Extra - Phone Mount Charger for Motorcycles- In this case I wired a second USB Charger plus phone mount for redundancy. Eventually all chargers end up failing, so this way I at least have a backup. Plus, these are just as good as the Ram Mounts in my experience.
*For Versys - Relay Kit- If you're installing on a Versys, you'll also need the Kawasaki Relay kit, too.

Tools and Supplies - (Within parenthesis means optional)

Since people tend to end up wondering what I used, I'll try to include links for everything just in case. Most of this you'll already have, or you won't want to use. But at least the list helps you find everything in your garage before starting the project.

Screwdrivers
Multimeter
Hobby Knife
(Soldering Iron) - I really like this unit because of the long cable (great for working on vehicles), adjustable temperature, and On-Off switch.
(Rosin Core Solder)
(Adhesive Heat Shrink Assortment)
(Liquid Electrical Tape)
(Ratcheting Terminal Crimper) - This is a must-have for automotive electrical work. It's the only right way to crimp terminals. If you get one, make sure it includes multiple jaws. The one I use (albeit a little expensive - but worth it) is this crimper.
(Dielectric Grease)

Kawasaki Original Part - DC Power Outlet - 99994-0485

While we should definitely be grateful for Kawasaki to finally include an OEM location for the power outlet, their OEM part is ridiculously overpriced and should hardly be considered. Their component has an MSRP of 84.95$ and is no better than any outlet you can find in the discount bin of your local AutoZone. The only benefit is that it comes with the wiring harness pre-made, but that's a sub-1$ part with standard components that most of us will already have. Nonetheless, if you would like to see the part, this is it: Kawasaki 99994-0485 DC Power Outlet.

Step 3: Remove the Fairings

Sadly, you're not going to be able to install this with the fairings in place. The first step is to remove the side fairings. While you should be able to complete the project with just the side fairings removed, it's very little extra effort to remove the headlight. You might as well remove it too, if you have the time and patience to do so. It will make your life easier later on.

Step 4: Remove the Panel Blank and Test Fit the Charger

You'll need a phillips screwdriver to remove the single screw holding the dash panel blank in place. Remove it and push the blank out the front.

This would also be a great time to just confirm that the charger you have is the right size. Test fit it and make sure you're satisfied.

Step 5: Find the Wiring

Confirm that your bike has the wiring to power the socket. It's already fused upstream, so you shouldn't have to worry about adding a fuse here (but it wouldn't hurt, either). The connectors are 4mm diameter bullet connectors, which are the standard ones. The female bullet connector (pictured with the green sleeve) is the positive (+12v), whereas the male bullet connector is Ground (0v, or "connection to chasis). Do not connect them together! That would be a short circuit and a blown fuse.

Step 6: Make the Harness

You'll need a short stretch of wiring to connect the cables from the bike side (bullet connectors) to the spade connectors on your charger. The wire only needs to be 3-6 inches long, to your preference.

Personally, I tinned the wire before attaching the crimp connectors since it helps make a more mechanically secure connection, and I imagine would also help keep the wire from wicking up water (to a small degree). However, If you do this, strain relief is crucial. This is debatable however (and very controversial, oddly enough), so it's by no means obligatory. If you aren't familiar with the topic, I'd really recommend you check out this article on whether crimping or soldering is better on a vehicle.

In my case, I decided to wire two chargers in parallel. I don't intend to use them simultaneously (I doubt the bike's wiring is designed to take it), but since I have had plenty of motorcycle USB Chargers fail me in the past (water gets into the port, bend the connector, random spontaneous death) this time I decided to install a backup charger. That way I can use whichever one suits me better. Plus, to my surprise the X-Grip Phone holder that came with it is just as good (if not better) than Ram Mount's version. The ball connector arm is metal (Ram Mount's is plastic), the size of the X-Grip is better suited for my smartphone (it doesn't touch the power/volume buttons), and it doesn't wobble (When gripping something, Ram Mount's design wobbles due to poor design). After finishing the project, I'm glad I decided to do this. If you don't want to (which is fine), just don't add the white male connector.

You'll have to add a male and female bullet connector to the wire to connect to the bike. On the cable your making, the male connector will connect to the +12v female bullet connector on the bike side, and the female connector on the wire side will connect to the male ground 0v bullet connector on the bike side.

Once you're sure everything is right, crimp the connections.

Step 7: Test to Make Sure It Works

Wire it up, without yet installing everything in place, and make sure it works.

Step 8: Install Permanently

Once tested, install everything in place, organizing the wiring and tightening things up. I'd recommend putting a dab of dielectric grease on all the electrical connections to help with waterproofing.

Step 9: Extra - Current Test. So You Don't Have To.

When using a smartphone on a motorcycle as a GPS (brightness maxed out for sun glare) and music player (for the Sena bluetooth Intercom), your phone's current draw is going to be as high as it can be. With most budget chargers, you'll be lucky if you can maintain battery charge. Not all chargers will actually be able to charge your phone while you're using it this way. And the same applies to charging cables, which is why I test my chargers and cables before putting them in use to make sure I have a properly working pair.

Here I used a DROK LCD Pocket Digital Multimeter USB and a DROK Micro Load Tester Board along with a high quality Anker PowerLine+ Micro USB (3ft) to make sure that both chargers lived up to their claims of 2 Amp charging current. The X-Grip charger passed flawlesly (though I wouldn't recommend even a bit over 2 Amps, as it was getting toasty), whereas the MicTuning went in to over-current protection mode and would not power up the test board. It may have been due to some USB protocol issue, since it didn't want to turn on even when the test board was set to lower current draw.

The conclusion is that the X-Grip charger is probably a more brutish charger with less self protection, but it will put out the 2 Amps. I guess the MicTuning might be able to put out 2 Amps on a single port, if your lucky, but I think it's designed to go into protection mode at around that amperage. Whether or not that matters in the real world is up to debate. The most my Samsung Galaxy S5 wanted to take in was 1.20 Amps, which is a decent charging current. I would have liked to see more, but it's hard to know if that's due to the charger not being able to output more, or my phone simply not wanting or needing to charge faster. In any case, in the real world an output above 1 Amp is pretty acceptable.

Note:

While the quality of a charger (read output) is more important than the quality of a cable, it's also easier to pick out the good chargers then it is to pick out good charging cables. Not all USB cables can put out 2 amperes.

In my experience, half the time my phone isn't charging quick enough, it's because of a free, no name charging cable. I definitely recommend testing any cables before putting them in to use for high current draw applications like this. You'd be surprised how many cables are out there that won't go above .7 amps even when the charger can perfectly output it.

Step 10: Enjoy!

Well that's it!

I hope it was helpful, and that the setup will last you plenty of miles to come. If you pulled off the project, please indulge me and post a picture below (at least so I know my time writing this up wasn't a waste).

Good afternoon,
Just wrapped up the double USB/Volt Meter installation on a 2019 Versys 650 LT. Dummy opening needed minor sanding to fit the gauge in,no big deal. After removing the side fairings and then windshield and top front cowling cover I realized it was not necessary to remove any side fairings at all.
Also the relay was already factory installed and the wires were already in place.
It works beautifully.
I already installed a GPS and that needed a relay and the blank connector is there and ready for the relay.
Thanks

I'm confused about the relay. I want to install a regular "hollow" cigarette socket on my wife's Versys 650 for an Anker charger, like you do in a car. Does the relay plug in somewhere else to get 12v? Are the 12v wires available? Do those factory bullet connectors not carry full current? I haven't torn any fairings off yet because she's gonna be pissed if I start experimenting on her bike. Is it the option of a) using the relay or b) running wires straight to the battery?

Question 2 years ago

Hi!
Was able to remove dummy plug using an offset ratchet with a #1 Philips in it - no need to remove any fairings or anything else (re: 2018 Ninja 400 KRT).
BUT - I'm not getting any current thru the Ninja's accessory wires - tested them with three voltmeters.
SO- I'd like to check the fuse that is supposed to be in the accessory wires, but I don't know where it is. It's called "fuse box 2", but I don't know where it is, though I've located the main fuse box.
Please advise the location and how to access it.
Many thanks!
Kawasaki Kid (who'll be 75 tomorrow)

Question 4 years ago

I've noticed the Versys needs a relay kit. Does anyone have any further info on this. Interested in why this bike requires it and others don't.
Thanks Michael

Anyone wishing to do this same mod on the new kawasaki z900 the two wires are located next to the parking light bulb behind the front light.

Question 4 years ago on Step 5

For the 2017 Ninja 650, I have a GPS hard-wired to my battery currently, which I'm not a fan of. I want to instead hardwire it to the accessory outlet/connection. How were you able to find the wires to the accessory outlet, and were those wires just there with capped for the optional 12v from factory or did you have to tap in from somewhere else? Other question, does the 12v charger turn off with the key?

Thanks!
