USB O-108, 3300mA USB charger with battery auto protect off, weatherproof, SAE, in & out cables

Best I've seen on the market: - 3.3a: plenty of current to charge newer phones vs most are only 2.1a - auto shutoff to avoid draining your battery without having a manual switch, only one on the market I've seen that has auto shutoff - the circuitry / bulky part of the cable is in the middle of the cable so it can be easily hidden with a smaller wire that runs to the USB port, most of the rest put the bulky circuitry around the USB port which makes it harder to cleanly install and requires a larger cable run to your phone. - integrated slot to easily zip tie the USB port in place - well made / high quality / reputable company

I have this hooked up on my Himalayan and simply ran the line underneath the tank to the existing SAE adapter I have on my battery. When I need to charge my phone while riding, I simply plug this into my SAE plug and then plug the USB into my phone's cable - job done. It has worked very well and seems to be of a much higher quality construction than some of the cheaper Chinese ones that I tried before this that either never worked or broke soon after using. So far this one is going strong and it's definitely waterproof.

I cannot comment on it’s performance yet as I am still in the process of it’s custom installation it into the car. I purchased it because of the greater charge capabilities and the 3 hour cut-off feature that will preserve battery drain for extended periods of inactivity. Time will tell how well it performs but I have no reason to doubt this product before actually using it because over time I have totally switched over to other Optimate chargers and have been impressed and quite satisfied so far with the quality of their products.

I don't think I bought the right cord. It was built really well, but it didn't get enough power from the solar panel I have installed on my car to charge anything. I recommend it in any other case than that. lol

Worked as advertised. Easy to install. I have had it a month and so far so good!

This converter was a life saver for yearly motorcycle trip. I ran the power to the handlebar area and pulled my smart phone into it for GPS location. I was able to tuck the adaptor into the battery area. I definitely recommend unhooking the adaptor over a long period of none use. Key feature I like is the female plug in has a cover to prevent water from getting into it.

Worked great for a month or so, now it lights up but won't charge anything

Best USB cable for Motorcycle. It was installed in My BMW 1600GT and it bworks as my pramary charging source.

Die Zeiten sind vorbei, wo bei Motorrädern Zubehör über die 12 V-Steckdose angeschlossen wurde. Ein Garmin-Navi benötigt 5 V, genau so wie man bei längeren Ausfahrten dankbar für Ladestrom fürs Smartphone oder andere Geräte mit USB-Anschluß ist. Das Optimate 108 ist zwar als "Schnell-Ladegerät" beschrieben, da der Strom aber bekanntlich nicht vom Ladegerät gepumpt, sondern vom Verbraucher gesaugt wird, gibt es da keine Problem, insbesondere weil ein Fz.-Batterieschutz vorhanden ist. Dieser verhindert, daß die Fahrzeugbatterie untere ein bestimmtes Level entladen wird, wenn der Motor nicht läuft und ein Verbraucher eingestöpselt ist. Die wasserdichte USB-Steckdose kann ganz einfach mit einem Kabelbinder unauffällig am Lenker befestigt werden, das eigentliche Ladegerät irgendwo am Fahrzeug. Mit 200 cm ist das Kabel ausreichend lang (Ladegerät etwa mittig). Falls man noch ein älteres Batterieladekabel mit TM-Stecker hat, hilft das Adapterkabel 07, um das Ladegerät anschließen zu können, wenn man nicht gleich den Festanschluß an der Batterie umrüsten möchte - Adapter und Ringösenkabel kosten etwa gleich viel. Zwar sind USB-Ladegeräte für den Zigarettenanzünder wesentlich preiswerter, allerdings habe ich so meine Zweifel, was Wasserdichtigkeit und Vibrationsresistenz beim Einsatz auf dem Motorrad betrifft. Insofern denke ich, daß der Mehrpreis beim Optimate gerechtfertigt ist.

Perfecto, de buena calidad y se auto apaga a los 30 min de desuso. El único pero es que venía con 2 cables gratis para dispositivos móviles, gracias, pero los 2 sin de conectores iPhone y en mi caso y creo que de muchos tenemos Android...

Works great so far , doing what it's suppose to do. I like the fact this has the same plug as my trickle charger,so switching is easy.

Envoi très rapide, arrivé bien avant la date prévue. Du peu que je l'ai essayé il fonctionne parfaitement. A voir avec le temps mais pour le moment c'est parfait ! Très content globalement

Installato su BMW r1200r LC per disporre di una presa USB nella parte anteriore della moto. Chi lo acquista prima consideri bene le misure della moto in relazione alla lunghezza dei cavi del prodotto. Io ho lasciato sotto la sella pilota la parte elettronica del dispositivo ( quella con i led) e fatto passare sotto le coperture del serbatoio il cavo di 1mt con all'estremità la presa USB, che ho fissato al telaio sotto il navigatore. Prodotto di qualità che ne giustifica il costo.
