Optimate Tecmate USB O-108 KIT, Smart 3300mA in-Line USB Charger with Sleep Mode and Vehicle Battery Controller.

I used this for my cell phone while running deliveries for DoorDash. So and go connect and disconnect frequently. Yet the optimate kept my phone charged and above 80% all day. The ordering, delivery,and packaging 📦 were exalting what I'd expected. I am very pleased.Thank YouExcellent Service!

This was a great purchase for my 2020 HD Breakout 114. 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.

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...???

Very nice charger to have installed for an all day ride. Was easy to install and I’ve enjoyed using the product. Arrived fast and no issues so far.

These SAE/USB chargers are excellent. However, I noticed my phone would frequently quit charging on a 2019 KTM 300xc that was running an aftermarket headlight which basically used up ALL the available wattage from the stator. Puzzled, I ordered another and quickly had the same problem. Turns out the protection circuitry was cutting off the power when the bike charging voltage was low at low RPM. I had to go back to a lower quality "dumb" charger for that bike. However on bikes with larger stators and more useable excess power, these are absolutely fantastic. They will definitely turn off below a certain voltage though, so keep that in mind.

Easy install

This product is well constructed and works as a USB charger but had to deduct 2 stars because within a week of installation it drained my battery and my motorcycle wouldn't start. I left it on but disconnect it after every ride and it hasn't been an issue since. Annoying to have to do this but it is what it is.

Bought this one year ago for powering my wireless charger for my phone on my 2021 Road Glide Limited. I installed it last July, 2021 and now it has stopped working. Lights come on but there’s now power coming out of the USB end. Never really got to use it. Was part of my setup for this summers touring.
