BATIGE Motorcycle USB Charger SAE to USB Adapter Type C and Quick Charge USB 3.0 with Voltmeter, ON/Off Switch and 3.6FT SAE Extension Cable Waterproof 3 Install Options for GPS Smartphone Camera

This works perfectly for what I need, just re-routed my sae leads to the bars and connected the charge port. The beauty is that I can just disconnect the sae connection to plug in my optimiser. A 3ft lead is supplied if you don’t have an sae already on your bike it was just easier for me to just move my existing cable. Update, as of the 2nd May it’s totally packed up, Definitely not weather proof, it was mounted on the bars behind the screen and only been out in the rain a few times since it was purchased on 16th February, I definitely won’t be buying another!

la carga rapida funciona excelente facil de instalar y el medidor de voltaje muy buena adicion

I originally tried the SAE USB charger from Battery Tender, but I found out it was SLOW to charge my S23 Ultra. I decided to return that and buy this little device instead. Installation was easy and only required me to take out my seat and connect it to the existing SAE harness and it worked flawlessly. Using a USB-C to USB-C cable will give the fastest charge to most phones. If it was able to fast charge my Samsung, it'll easily do so for any iPhone as well. Plus the battery voltage meter is awesome for those who like more info about their bikes. Plus it has a button to easily turn off and on, and have never had it drain my battery to the point of not starting.

車のバッテリー上がりしない様に電圧の確認に使っています。

These have an on/off toggle switch. When connected to a switched source, the units reset after each power cycle and must be turned on again to allow power to flow. This is not ideal for most applications.

Works as stated. Happy either way purchase!
