Good USB socket w/ one flaw
This USB socket works great and the waterproof cap definitely keeps the seal.

I have one complaint about this socket. It has blue LED lights that are always on when the device is powered on! This is a problem if you plan to do a direct connection to the battery because it will drain your battery (albeit slowly).

I ended up splicing the wires from this device onto my options plug wires under my seat so that this socket only powers on when my ignition is on. This keeps my battery safe from draining. The downside of this solution, though, is I have to have my ignition on to charge/power anything via USB.

If those LED lights were gone, it'd be better. Otherwise, this socket seems to be great quality.

Works good, looks good, hate blue light
Although I like having USB power on my bike, I really dislike having a blue light staring at me whilst I ride at night. I keep thinking my brights are on! The other complaint I have on this was that the wires were not long enough to reach the fuse block near my battery on my 2001 Yamaha FZ1, so I extended them to add the reach needed for a proper install. Also of note, there was not enough charging power to keep my phone (Samsung S3) charging faster than it was using power while I was using GPS and Pandora on a road trip. Still way better than nothing though!
Despite a few shortfalls , I would still recommend this product.

great product
Great product. I decided to take the USB socket off of the bar clamp it comes with and very carefully cut a big hole (big) in the plastic on my dash! Fits very nicely and looks part of the bike. The socket even glows blue!! Seems a much better idea than a cigarette lighter as smoking and riding kills!! Seriously though everything is USB these days so cut out the cigarette lighter socket and just have one off these?

Best Bang for the buck for Bike USB power
I live in Northern Japan and planned on doing a long camping ride across the entire northern half of Japan. Most of the time I would not have access to electrical power so this was a best bet to keep my cell phone and GPS powered up. It did a great job of it. I also ran an extra long USB cable back to my road pack where I keep a powerbank for in the evenings if I want to power my tablet or anything of the sort. The power output of the two sockets combined is only 2A but on a longer ride this is not an issue. However, don't expect to ride down the street to the 7-11 and have your iPhone charged by the time you get there. It is decently waterproof with the cap on, I had no issues with this. I do wipe it down on the inside with a tiny bit of silicone grease and I think that helps. So in the best for your money category I would say this one wins.

Does the job!
Installed this in the plastic fairing of my bike so that my Garmin Monterra would have power and I'd have a USB for other purposes as needed. The result has been spectacular.

I hooked the device up to a relay that also switches my heated grips, so power goes on and off with the ignition. I removed the fuse and rely on the larger fuse that I put on the relay.

Installation is simple. Just hook up the 2 wires and either use the included handlebar clamp or create a mounting hole. The unit is sealed, so as long as the cap is in place, it won't get wet. With the cap off, water can get into the ports, but that too can be helped with careful selection of cable ends. I mounted my unit out of the main airstream, so even in the wet, the water is not driving at the ports.

The blue glow lets me know that power is on which is a nice feature. It is bright, so be careful where you mount it. I have mine under my handlebars so that most times I don't see the light unless I move. In the attached photo, I've turned my bars fully to the right so that I could take the photo.

The output is 2 amps total. So, if you have more than one device plugged in, you can't charge them both at full power.

The cap is a nice flexible rubber, so when you have it off the ports, you don't need to worry about things hitting it. For example when I turn my bars all the way to the right, my fork can hit the cap. But it just crushes with no resistance.

All in all, I think this is a great MC port if you have a need for handy USB power. While there are cheaper ways to do it, having the piece of mind that it's weather proof is worth the extra money.

works well
Works well but it should have a longer harness! I had to cut, splice and shrink tube 6" on to it just to get it to my battery. And that was from the bars supposedly you can attach it to your mirror but I would have been about a foot short.

Just in time...
Bought this a some time ago. It came in earlier than expected. The install was easy. It took more time to put the bike back together. Which was two days before my trip. Over 1400 miles and charged the phone, GPS, and Sena SMH10 (also a Revzilla purchase) perfectly. With the cover in place I had no reason to worry about all the rain I encountered on or since this trip.

Works Great
Works just as stated. I use this daily to charge my phone while driving. I have had no issue with the 2,000 miles I have ridden with it. Blue light is always on when it has power. Not really a downside or anything. Also waterproof door works great.

love this, if i had to find something, it would be the rubber cover ,when you have cords plugged in. the cover hangs down and flys around in the wind. wish there was something to snap it onto, or something. but really thats the only thing i can come up with.

Long road trips on the FZ-09 and the powerlet option was insanely expensive. $150 plus 50 for a droid charging cord? That's ridiculous.

The dual USB ports will allow me to charge both my phone and GPS from a single power source. I like simplicity:)

Kaci L on Feb 8, 2015
I like that the power available is 2A. You find many usb ports but tbey are rated at only 1A which won't charge phone or tablet devices. This is also a double usb port which is even better!

Looked like a good way to keep my phone turned on. We 'll see.

mike m on Aug 7, 2014
Need dual-USB capability on my Tiger 800. The inclusion of power outlets on many bikes is nice, but the "powerlet" type socket usually inclouded is pretty useless for powering the most common devices, which are all phone-based these days. Ideally somebody would make a compact powerlet-to-USB adaptor, but the only existing one is both backordered and rather large. This will mount easily to the bike's frame next to the existing powerlet and I'll splice into the existing wiring.

Carina S on Sep 18, 2016
Is this an SAE connection?
Yamaha_Panda on Feb 16, 2014
BEST ANSWER: I did not purchase this bar mounted socket however understanding is purely a duel USB outlet and will require hard wiring to a power source direct or switched.
will this draw current when not connected to a USB device and drain the battery?
A shopper on Feb 15, 2014
BEST ANSWER: Yes. The blue light/panel is on when it's connected. It will charged devices when the bike is off, since it's connected directly to the battery (unless you've installed an on/off switch between it and the batter).

So, be wary, it will draw a small amount of current due to the blue light. I'm not sure how much that is though, unfortunately.
Does this come with the cables necessary to connect to the power source?
Luke D on Mar 1, 2014
BEST ANSWER: As indicated in the description it comes with all the wires to connect to battery including an inline fuse.
I'd like to know if its 2.0 amps each outlet or total for both ??????
A shopper on Jun 6, 2014
BEST ANSWER: Each outlet is 2.0 and works great. I have had my iPhone and ipad charging at the same time no issues.
Does this provide 2 Amps total, or 2 Amps for each port?
Patrick T on Mar 27, 2014
BEST ANSWER: the fact that it will charge an iPad I am guessing 2amps per port.
Can it be mounted on handlebars?
Yousuf S on Feb 1, 2014
BEST ANSWER: "Fits 7/8" to 1" handlebars"
Has anyone put this on a drz400? Can the wires reach from the handle bars to battery? Looks like it would be really close.
