This is an original TomTom accessory, is good value compared with some other sellers and works well. Bought as a spare for a TomTom Start 60, for which you have to use the additional micro usb adapter supplied with it. The lead is the same length as the original which came with the sat nav at about 1.5 metres including the usb plugs on either end (full size USB and mini USB - the separate micro USB adapter fits onto the mini USB plug). ACCORDING TO THE BOX in which it comes, this charger is compatible with the following TomToms as well as "MP3 players, mobile phones and more": "Start series; ONE New Edition; ONE 3rd Edition; ONE 30 series; ONE IQ Routes Edition; ONE XL; XL series; XXL series; Via Series; GO Series numbers 20, 30, 40, 50, 800, 1000"; BUT I note from a few other reviews that a few TomTom ONE and XL Live IQ owners have had problems. Hope all this helps someone, but please don't blame me if it doesn't fit your kit, I am only the messenger!!
