Has to be combined to be effective, but works great
Had to combine this with the Optimate O1 and the O110 so it wasn't bloody cheap, but it performed excellent and I've little doubt that it'll stand up to a lot of use.

Good quality lead but lacks 5 stars
This is an excellent product and comes with a long lead to charge USB devices. There's also a 'free cable' with it which connects to the battery and can be used with both the USB charging lead and Optimate chargers. This free lead can be permanently connected to the bike and has a weather-proof cover on the open end but (here goes...) sadly the USB charging lead doesn't have a similar cover at the corresponding SAE end, hence only 4 stars. There is a cover on the USB socket though. While I'm sure the USB to battery lead provides a good seal when connected, it does mean that the open end is at the mercy of the elements and for that reason I don't now want to risk connecting this USB lead permanently to my bike (that's what I'd intended). For the sake of an extra end cover (see picture of Optimate O1 which actually includes 3 of these in different colours) this would've been a 5 star product and had I known this before purchase I'd have bought the stubby USB charger instead (O100). With regard to charging though, the charger holds power for a while after the bike has been switched off and cuts out below a certain level so it doesn't keep draining the battery which is a good thing. UPDATE - I've decided to return this and buy the O100 charger instead - there's no point in carrying a pocket full of cable around as well as the charger.

Works well
Does the job and won’t flatten your battery. Only downside is finding where to hide the extra hardware.

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

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
