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.
