I've had this for a few months now and have had no issues with it at all. I have ridden in heat, rain, and cold with it. It is easy to wire in and allows me to not have to disconnect my USB charger to prevent the battery from draining (many of them keep pulling some juice, especially if you have a wireless charging head on your bike. The unit will stay active for one hour after I turn off the bike (so I can still charge the phone for a bit) but automatically turns off after that. It also has a meter that gives you an idea of the battery condition. The end of the chord where you plug your device's USB cable into has a gasket around it that is easy to plug into but does a great job at keeping water and dirt out. Be aware that the unit is one continuous chord with the power box in the middle. Not a big deal, but good to be aware of when you are planning how to run the wire through your bike. Very pleased with this purchase. Review: Outstanding Equipment Upgrade!!! - Actually the cabling can be a bit longer than needed. Howe6, it is most definitely there for when you might actually need it. As in a jump another motorcycle situation, so the length of the cable is most likely shorter than you really are going to need it to be. This is definitely an add on that I have already recommended numerous times. It's on you to listen to that recommendation and do something about it. BTW why are you still reading this and NOT ordering...??? ## Features - Included battery lead allow this kit to work with any motorcycle battery. - 80" cable allows you to mount in the best location on your motorcycle. - Weatherproof. - Built in protection to turn off when not using. - Monitors battery status with easy to read led indicator. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07R1MKK4B | | Amperage | 3.3 Amps | | Best Sellers Rank | #524,057 in Automotive ( See Top 100 in Automotive ) #1,217 in Battery Chargers | | Brand | OptiMate | | Built-In Media | O108KIT | | Color | Black | | Connector Type Used on Cable | USB | | Current Rating | 3300 Milliamps | | Customer Reviews | 4.4 out of 5 stars 88 Reviews | | Input Voltage | 240 Volts | | Item Type Name | USB | | Item Weight | 160 Grams | | Manufacturer | TecMate International NV/SA | | Mfr Part Number | Tecmate-O108KIT-DE | | Model Number | O108KIT | | Number of Ports | 1 | | Output Voltage | 5 Volts | | Warranty Description | 3 year limited | ## Product Details - **Brand:** OptiMate - **Color:** Black - **Input Voltage:** 240 Volts - **Item Weight:** 160 Grams - **Output Voltage:** 5 Volts ## Images ![Tecmate USB O-108 KIT, Smart 3300mA in-Line USB Charger with Sleep Mode and Vehicle Battery Controller. - Image 1](https://m.media-amazon.com/images/I/51csy7W-obL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fast Charges and Automatically Turns Off *by D***X on February 12, 2021* This was a great purchase for my 2020 HD Breakout 114.
