BATIGE 4.8A Dual USB SAE to USB Adapter Motorcycle USB Charger, 3 Installation Options Waterproof for iPad GPS Smartphone Camera, with Voltmeter, ON/Off Switch and 3.6FT SAE Extension Cable

Has worked good for the riding season. We'll see if we can get a second season out of it.

Great mounting option for USB power on your motorcycle.Only wished the wire coding was all black with a small red pinstripe to dictate positive terminal.Other than that it works great , has a voltage meter built in and quick connects.

Does the job of keeping my phone charged on long rides. Don’t forget: unplug this or any other product like it when you’re not running your bike.

Plugged USB charger in and neither the volt meter or the USB charging sockets worked. I double checked to make sure my fuse was good and that I had voltage at the plug as well and that was fine. Disappointing since this was for my dirt bike and since it is the middle of winter, I was in no rush to install the charger. No I can't return it! Obviously, I can't recommend this charger.Update: I purchased another similar charger and had the same issue. I ended up figuring out that some of these cheap USB charger/volt meters have reversed polarity for some reason. It may be worth your time to re-wire your SAE plug to reverse the polarity (be sure to put the fuse on the positive side) or buy a more expensive charger.

This is not only a great product for your bike if you want a USB charging system, it's a great tool for anyone tinkering with 12v systems. In my car, I wanted to add a USB charging port that wasn't connected to my car's Android Auto system, for those moments that I just want to charge but not invoke AA. This can easily be connected to any 12V line (I spliced behind the DC port) and mounted it inside a storage bay. The LED display is a nice addition because it can tell you how the battery is doing (to avoid running it down) as well as help diagnose things like alternator issues and overall electrical health.

I'm using this on an Ender 3 V2 printer to drop the 24VDC power supply down to healthy 5VDC to power my Raspberry Pi 3 and some LED lighting. The installation was really simple and this box is easy to mount on the side of the 4040 railing base. The Pi 3 doesn't complain about low voltage with this provided it has the right cable.

I have mine hidden under my motorcycle seat and u have to turn it on every time you want to use it

Rain into rain on a ride. Charger got wet and stopped working. Even after a week in the garage still doesn't work. Display still turns on but puts nothing out. Even cut up a old charger so I could check it with a meter. No voltage found.
