Motorcycle USB Charger, Mroinge 6.8A SAE to USB Adapter Dual Port QC3.0/2.0 Fast Charge, with Voltmeter/Ammeter & ON/Off Switch & 10A Fuse, Perfect for Your Phone or Smart Device Charging

I bought the one with the two turbo 3.0 ports. Works very well so far, and this model features a built-in voltmeter, allowing you to monitor your battery. I have had similar devices, and you have to be careful if you have this on your motorcycle and go to a high-pressure car wash. It has a cap to protect the ports, but the power switch on the side is not able to handle high-pressure spray. For its price, it's a great choice, just take care at the car wash.

Works on a 2019 HD Road King. The plug slips into one of the several battery adapters. If you loosen the screw holding the tank cover on you can hide the wire under the seat and tank cover. Have the usb ports coming out the front by the handle bars. Two usb ports work great. The dust cover stays tight and keeps rain out. There’s a small switch on the side so you can turn the cord off so it isn’t using your battery when you don’t need it. It ain’t the prettiest thing but it works really well and ships quick and that’s all the matters.

Good works

Fast charging.ive had others with smaller wire and took forever to charge.this one is fast

Update: I posted my initial review after the product stopped working. The product company, Mroinge, read my review and provided a replacement without me contacting them and asking for a replacement. That tells me that they make a quality product and that my experience was not typical. They certainly are very customer focused and that speaks volumes about their expectations of their product. I have updated the review from 3 to 5 as a result of their stellar care and proactive engagement. Wow! ---------------------------------------------------------------------- I liked the product initially, for a few reasons. Easy to read display, on/off slider switch, compact size, SAE, etc. Used it in an outdoor setting. Connected to 12V battery and powering a WiFi security camera via USB. My configuration worked for a few months with no trouble but died this week. I tested all the components; this was the one that failed.

inexpensive but seems well made. Long wire to battery, but do a rough measurement along your desired path because it takes more to work around substructures and hot areas. Used it on a trip and once since, worked well, charged well. Nice to be able to turn it on and check voltage of my battery before start up or while on the road too. Charges rapidly, super charger.

If you do not have a existing battery cable you will need to purchase one that connects to your battery so you can plug it into your USB phone charger

Works great orientation of the LCD screen will be upside down if you want the USB plugs facing up.
