I don’t use the battery indicating feature, I just use it as the power supply for my Quad-lock for which it works very well.Works as advertised, though I have not tested the the weather-proof capabilities as yet. Able to keep my phone charged and not have to worry about a dead phone OR a dead motorcycle.thank youLove it works great on my bike the USB is a nice featureAwesome charger and a perfect fit for my R1200 GSA. It’s compact and streamlined and tethers nicely to the frame with a tie strap. The auto shut off function has already saved my battery several times.Very easy to use, charges as expected. I have a '21 Ducati SFV4S and the unit unfortunately interferes with the transponder in the key. Constantly asking to enter the Pin code to start the bike. When I remove the unit everything starts as expected. Pretty frustrating.Keeps the phone charged while using it for GPS and not to worry about it running the motorcycle battery down when parked.Works as expected.Easy hack for charging your device while on the road.. definitely recommended..Highly recommended, with one caveat...make sure it is properly attached!! Other than that I can't fault it.It's designed to be compatible with the Optimate charger leads and so is very easy to install.. You could literally do it with your eyes closed.I've docked it one star because it came undone and I lost it. Maybe I should have checked it regularly but I obviously didn't expect that to happen.I would give it five stars if it had some sort of clip to hold it in place. That said, I will be buying another and will be more careful in future.Didnt work for me.Questa azienda produce molte combinazioni spina/presa/accessori che consentono il collegamento e l'uso di accessori per la moto, sono ben realizzati e ben confezionati.
